Understanding how your thyroid medication works is key to feeling your best. Common advice usually points towards taking it on an empty stomach, often first thing in the morning. This is because your body’s absorption process for thyroid hormones is pretty specific, and certain things can really mess with how well they get into your system. Factors like what you eat, other supplements you’re taking, and even your sleep patterns can seriously influence whether your medication is hitting the mark.
Understanding Thyroid Medication Timing

The question of when to take thyroid medication is a common one, and for good reason. Proper timing is crucial for ensuring your body can effectively absorb and utilize these vital hormones. While individual circumstances can vary, understanding the general principles and influencing factors can empower you to optimize your treatment.Thyroid hormone replacement medications, most commonly levothyroxine, are designed to mimic the natural hormones your thyroid gland produces.
The body’s ability to absorb these medications is highly sensitive to various substances and physiological states. Therefore, understanding the absorption process and the factors that can interfere with it is paramount to achieving therapeutic success.
Common Recommendations for Thyroid Medication Intake
The prevailing advice for taking thyroid medication centers on consistency and maximizing absorption. This typically involves taking the medication on an empty stomach.The most frequently recommended schedule for thyroid hormone replacement therapy is to take it first thing in the morning, at least 30 to 60 minutes before breakfast. This allows for optimal absorption before food, beverages (other than water), and other medications are introduced, which can impede the hormone’s uptake.
Another acceptable, though less common, recommendation is to take the medication at bedtime, at least 3 to 4 hours after the last meal. This also ensures an empty stomach. The key is consistency; whichever timing is chosen, it should be maintained daily.
Thyroid Hormone Absorption Process
The absorption of thyroid hormones is a complex physiological process that primarily occurs in the small intestine. Once ingested, the medication needs to dissolve and then be transported across the intestinal wall into the bloodstream. This process is influenced by several factors, including the presence of food, other medications, and certain medical conditions.Levothyroxine, the synthetic form of thyroxine (T4), is absorbed efficiently when the gastrointestinal tract is clear.
The absorption rate can be as high as 80%, but this can be significantly reduced by interfering substances. The hormone then binds to transport proteins in the blood, such as thyroxine-binding globulin (TBG), and is distributed to tissues throughout the body, where it is converted to the more active form, triiodothyronine (T3).
Factors Influencing Thyroid Medication Effectiveness Based on Timing
Several elements can impact how well your thyroid medication works, particularly concerning the timing of its administration. These factors range from dietary choices to other medical conditions and medications you may be taking. Recognizing and managing these can significantly improve treatment outcomes.The effectiveness of thyroid medication is profoundly influenced by what else is present in your digestive system when you take it.
- Food and Beverages: Many common foods and drinks can interfere with thyroid hormone absorption. These include high-fiber foods, soy products, walnuts, and calcium-rich foods or supplements. Coffee, in particular, is known to reduce absorption if consumed too close to taking the medication.
- Other Medications: A wide array of medications can bind to thyroid hormones in the gut, preventing their absorption. This includes antacids, iron supplements, calcium supplements, bile acid sequestrants, and certain proton pump inhibitors. It is crucial to discuss all medications and supplements with your doctor.
- Medical Conditions: Certain gastrointestinal conditions can affect the absorption of thyroid hormones. Conditions like celiac disease, Crohn’s disease, and atrophic gastritis can lead to malabsorption, necessitating dose adjustments or alternative administration methods.
- Age and Health Status: Absorption can also be influenced by age and overall health. Older individuals may have slightly reduced absorption, and those with significant weight fluctuations might require dose adjustments that indirectly relate to how effectively the medication is being utilized.
“Consistency in taking thyroid medication, ideally on an empty stomach and at the same time each day, is the cornerstone of effective management.”
The “Nighttime” Question for Thyroid Medication

The perennial query surrounding thyroid medication timing often circles back to the potential of a nighttime regimen. While morning ingestion is the widely accepted standard, exploring the feasibility and implications of taking thyroid medication before sleep warrants a closer look, considering both the physiological underpinnings and practical considerations. This delves into the nuances of this alternative timing.The human body operates on a complex circadian rhythm, influencing hormone secretion and metabolic processes.
Thyroid hormone, critical for regulating metabolism, is also subject to these natural fluctuations. Understanding how medication interacts with these rhythms is key to optimizing treatment.
Potential Benefits of Nighttime Thyroid Medication
Shifting thyroid medication to the evening may offer several advantages for certain individuals, primarily revolving around convenience and potential physiological alignment. The idea is to harness the body’s natural cycles rather than disrupt them.Some patients find that taking their medication at night simplifies their daily routine, particularly if they have complex morning medication schedules or tend to forget their dose amidst the morning rush.
This improved adherence can be a significant benefit, ensuring consistent therapeutic levels.Furthermore, there is a theoretical basis for nighttime administration relating to the body’s natural hormonal fluctuations. While research is ongoing and not definitively conclusive, some hypotheses suggest that taking thyroid hormone when endogenous production might be lower could potentially lead to more stable serum levels throughout the day. This could theoretically reduce the peaks and troughs sometimes associated with morning dosing, although this remains a subject of ongoing investigation and clinical observation.
Potential Drawbacks and Risks of Nighttime Thyroid Medication
Despite potential benefits, a nighttime thyroid medication schedule is not without its risks and drawbacks, which must be carefully weighed against any perceived advantages. The body’s physiological state during sleep differs significantly from wakefulness, impacting absorption and utilization.One of the primary concerns is potential gastrointestinal upset. Some individuals may experience nausea or discomfort when taking medication on an empty stomach before bed, which could disrupt sleep.
Additionally, the absorption of thyroid hormone can be affected by food and other medications, and the unique digestive environment during sleep might alter this absorption profile unpredictably for some.Another significant risk involves interference with sleep quality. While rare, some individuals report experiencing insomnia or restlessness after taking thyroid medication in the evening. This could be due to the stimulating effects of thyroid hormone on the body’s metabolism, even at therapeutic doses, leading to an inability to relax and fall asleep.Moreover, the established guidelines for thyroid medication timing are based on extensive research and clinical experience, emphasizing morning dosing to maximize absorption and minimize interactions.
Deviating from this standard without thorough medical consultation could lead to suboptimal therapeutic outcomes or unforeseen side effects.
The goal of thyroid medication timing is to achieve stable and effective hormone levels with minimal disruption to the body’s natural processes and the patient’s quality of life.
Comparison of Morning Versus Nighttime Thyroid Medication Effects
The comparison between morning and nighttime thyroid medication intake highlights distinct patterns in absorption, potential side effects, and overall therapeutic efficacy, though individual responses can vary significantly. The prevailing medical consensus leans towards morning administration for well-defined reasons.Morning dosing, typically on an empty stomach at least 30-60 minutes before breakfast, is the standard recommendation. This timing is believed to optimize absorption by minimizing interference from food, beverages (especially coffee), and other medications that can bind to thyroid hormone and reduce its uptake.
The body’s metabolic rate is generally higher during waking hours, potentially aligning better with the medication’s action.
| Timing | Potential Benefits | Potential Drawbacks | Primary Rationale |
|---|---|---|---|
| Morning (Empty Stomach) | Optimized absorption, reduced interactions with food/meds, aligns with active hours. | May require strict adherence to pre-breakfast timing, potential for morning nausea in some. | Maximizes bioavailability and predictable therapeutic effect. |
| Nighttime (Before Bed) | Convenience for some, potential for improved adherence, theoretical alignment with natural hormone cycles (less established). | Risk of GI upset, potential sleep disruption, variable absorption due to digestive state, potential for interactions with late-night snacks/meds. | Convenience and adherence for select individuals, with careful monitoring. |
While some individuals report success with nighttime dosing, often after consulting their physician and experiencing no adverse effects, the potential for diminished absorption and sleep disturbance remains a significant consideration. The lack of robust scientific evidence supporting superior efficacy or safety for nighttime use, compared to the well-established benefits of morning dosing, means it remains an off-label consideration for specific patient profiles under close medical supervision.
Factors Influencing Medication Timing Decisions

Understanding when to take your thyroid medication is not a one-size-fits-all proposition. Several external and internal factors can significantly influence how effectively your body absorbs and utilizes these crucial hormones. Ignoring these variables can lead to suboptimal treatment outcomes, even if you’re diligently taking your pills. It’s about creating a synergy between your medication and your daily rhythm, ensuring maximum benefit.
Interactions with Other Medications and Supplements
The digestive tract is a busy place, and when you introduce thyroid medication, it needs a clear path to absorption. Many common medications and dietary supplements can act as unwelcome guests, interfering with this process. These substances can bind to thyroid hormones, preventing them from entering your bloodstream or altering their absorption rate. This is why a careful review of all ingestibles is paramount.Here are some common culprits that can interfere with thyroid medication absorption:
- Calcium Supplements: Calcium carbonate, in particular, is notorious for its ability to bind with thyroid hormones. It’s generally advised to separate calcium intake by at least four hours from your thyroid medication.
- Iron Supplements: Similar to calcium, iron, especially ferrous sulfate, can significantly reduce thyroid hormone absorption. Maintain a similar four-hour separation.
- Antacids: Many over-the-counter antacids contain calcium or magnesium, which can also impede absorption. Check the active ingredients and consult your doctor or pharmacist.
- Proton Pump Inhibitors (PPIs) and H2 Blockers: Medications like omeprazole, lansoprazole, and ranitidine, used to reduce stomach acid, can alter the gut environment and potentially affect thyroid hormone absorption, although the evidence is less consistent than with calcium and iron.
- Certain Cholesterol-Lowering Drugs: Some bile acid sequestrants, such as cholestyramine, can bind to thyroid hormones.
- Multivitamins: Many multivitamins contain calcium, iron, or magnesium, necessitating a separation period.
Impact of Food Intake on Medication Timing
Food, while essential for life, can be a formidable barrier to optimal thyroid medication absorption. The presence of food in the stomach can dilute the medication, slow down gastric emptying, or chemically interact with the hormone, all of which can lead to decreased bioavailability. This is the primary reason for the common recommendation to take thyroid medication on an empty stomach.The type and timing of your meals play a critical role:
- High-Fiber Foods: While beneficial for overall health, very high-fiber meals consumed close to your medication can slow digestion and potentially affect absorption.
- Soy Products: Soy has been shown in some studies to interfere with thyroid hormone absorption. It’s advisable to avoid consuming significant amounts of soy products around the time you take your medication.
- Walnuts: Like soy, walnuts can also potentially impact thyroid hormone absorption.
- Coffee: The caffeine in coffee can affect gut motility and may even slightly reduce absorption if consumed too close to your medication.
The general consensus is to allow at least 30 to 60 minutes between taking your thyroid medication and consuming any food or beverages other than plain water.
Influence of Sleep Patterns and Disruptions
Your body operates on a complex circadian rhythm, and sleep is a fundamental component of this cycle. Disruptions to your sleep patterns, whether due to insomnia, shift work, or jet lag, can subtly influence your body’s hormonal balance and its response to medication. While the direct impact on thyroid hormone absorption from a single night of poor sleep might be minimal, chronic sleep disturbances can lead to systemic changes that may indirectly affect medication efficacy.The body’s natural hormonal fluctuations, often tied to the sleep-wake cycle, can influence how medications are processed.
For instance, stress hormones, which are often elevated during periods of sleep deprivation, can sometimes interact with other hormonal systems. While research specifically linking sleep disruption toreduced* thyroid medication absorption is limited, maintaining a consistent sleep schedule supports overall endocrine health, which is beneficial for managing any chronic condition, including hypothyroidism. A well-rested body is generally more efficient at processing and responding to treatments.
Sample Daily Schedule for Optimal Thyroid Medication Timing
To illustrate how to integrate thyroid medication into a daily routine while accounting for the factors discussed, here is a sample schedule. This is a general guideline and should be personalized based on your specific meal times, work schedule, and other medications.
| Time | Activity | Notes |
|---|---|---|
| 7:00 AM | Wake Up and Take Thyroid Medication | Take with a full glass of plain water. Ensure at least 30-60 minutes before breakfast. |
| 7:30 AM – 8:00 AM | Breakfast | Enjoy your first meal. If you take calcium or iron supplements, take them with this meal if it’s at least 4 hours after your thyroid medication. |
| 10:00 AM | Optional: Mid-morning Snack / Other Supplements | If taking other supplements (e.g., Vitamin D, magnesium), ensure they are not on the interaction list or separate them from thyroid medication by at least 2-4 hours. |
| 12:00 PM – 1:00 PM | Lunch | A balanced meal. |
| 3:00 PM – 4:00 PM | Optional: Mid-afternoon Snack | |
| 6:00 PM – 7:00 PM | Dinner | If taking calcium or iron, ensure it’s at least 4 hours after your morning thyroid dose. |
| 9:00 PM | Optional: Evening Supplement (e.g., Calcium/Iron if not taken with meals) | Ensure at least 4 hours have passed since your morning thyroid medication. |
| 10:00 PM – 11:00 PM | Bedtime | Aim for consistent sleep to support overall health. |
The cardinal rule for thyroid medication absorption is to allow ample time between ingestion and other substances, particularly food, calcium, and iron.

Food Type Interactions with Nighttime Thyroid Medication
The absorption of thyroid hormone replacement therapy can be significantly influenced by the types of food consumed, especially when considering nighttime intake. Certain food components can bind to the medication, hindering its journey into the bloodstream.When thyroid medication is taken at night, the presence of specific food types in the stomach or digestive tract can interfere with optimal absorption. This interference can manifest as reduced efficacy of the medication, leading to suboptimal thyroid hormone levels.
- High-Fiber Foods: Foods rich in fiber, such as whole grains, bran, and certain vegetables, can increase gastrointestinal transit time and potentially bind to thyroid hormones, slowing down or reducing their absorption. Consuming a meal heavy in fiber close to bedtime might compromise the medication’s effectiveness.
- Calcium-Rich Foods and Supplements: Dairy products, fortified plant milks, and calcium supplements are well-known inhibitors of thyroid hormone absorption. If a late-night snack involves yogurt, cheese, or a calcium supplement, it can significantly impair the medication’s uptake.
- Iron-Rich Foods and Supplements: Foods like red meat, spinach, and iron supplements can also interfere with thyroid hormone absorption. A late-night meal or supplement containing iron needs careful consideration to avoid this interaction.
- Soy-Based Products: Soy products, including tofu and soy milk, have been shown to interfere with thyroid hormone absorption. Consuming these close to bedtime, especially if the medication is taken without adequate separation, can lead to reduced efficacy.
- Walnuts and Other Nuts: While generally healthy, walnuts and other nuts can also contain compounds that may affect thyroid hormone absorption. A late-night handful of nuts, if not timed properly, could pose a minor interference.
Physiological Changes During Sleep and Thyroid Hormone Absorption
The body undergoes a series of profound physiological transformations during sleep, many of which are relevant to how thyroid hormones are processed and absorbed. Understanding these changes can shed light on the potential implications of nighttime medication intake.During the sleep cycle, the body enters a state of reduced metabolic activity and increased rest and repair. This period is characterized by a slowing down of various bodily functions, including digestion.
The gastrointestinal tract’s motility typically decreases during sleep, leading to slower transit times for ingested substances. This can potentially prolong the contact time between thyroid medication and any residual food particles or digestive juices in the stomach and intestines.
Furthermore, the body’s hormonal milieu shifts during sleep. For instance, cortisol levels, which are naturally high in the morning, are at their lowest during the early hours of sleep. While not directly impacting absorption, these hormonal fluctuations are part of the body’s intricate regulatory system that is influenced by thyroid hormones. The reduced physical activity and metabolic rate during sleep might also influence the rate at which the body utilizes the absorbed thyroid hormone.
Therefore, while the absorption itself might not be drastically altered by the sleep state alone, the subsequent utilization and the potential for interactions with late-night food intake become more critical considerations.
Navigating your health journey, understanding when to take thyroid medicine is crucial for your well-being. Just as you seek clarity on medication timing, remember that your primary care physician guides your overall health, and yes, can an internal medicine doctor be a pcp , offering comprehensive care. This expertise can also inform decisions like whether you can take thyroid medicine at night.
Specific Thyroid Medication Types and Timing: Can I Take Thyroid Medicine At Night

The choice of thyroid medication, whether synthetic or natural, significantly influences the optimal timing for its administration. Understanding these nuances is crucial for maximizing efficacy and minimizing potential side effects. This section delves into the specific timing considerations for various thyroid hormone formulations.The body’s natural thyroid hormone production follows a circadian rhythm, with peak levels typically occurring in the early morning.
Mimicking this pattern with medication can enhance therapeutic outcomes. However, the absorption and metabolism of different thyroid hormone preparations can vary, necessitating tailored timing strategies.
Synthetic Thyroid Hormones: Levothyroxine Timing
Levothyroxine, the synthetic form of thyroxine (T4), is the most commonly prescribed thyroid hormone medication. Its absorption is highly sensitive to the presence of food and other substances in the gastrointestinal tract. Therefore, precise timing is paramount to ensure consistent and adequate absorption.The gold standard for levothyroxine administration is on an empty stomach, ideally first thing in the morning, at least 30 to 60 minutes before breakfast.
This allows for unimpeded absorption. If taken with food, particularly calcium, iron, or fiber-rich foods, levothyroxine absorption can be significantly reduced. Similarly, certain medications, such as antacids and proton pump inhibitors, can interfere with its absorption.
Consistent morning administration of levothyroxine on an empty stomach is the cornerstone of effective thyroid hormone replacement therapy.
Some individuals find it challenging to adhere to the strict morning regimen due to work schedules, early morning appointments, or simply forgetfulness. In such cases, taking levothyroxine at bedtime, at least 3 to 4 hours after the last meal, can be a viable alternative. This allows for a sufficiently long period of gastric emptying, thereby promoting optimal absorption. It is essential to consult with a healthcare provider before making any changes to the medication schedule.
Natural Desiccated Thyroid Hormone Medications: Unique Timing Recommendations
Natural desiccated thyroid (NDT) medications are derived from animal thyroid glands and contain a mixture of T4 and T3 (triiodothyronine), along with other thyroid hormones and proteins. The presence of T3, which is more rapidly absorbed and has a shorter half-life than T4, can lead to unique timing considerations.While many NDT users also take their medication in the morning on an empty stomach, some find that splitting the dose into two or even three smaller doses throughout the day can help maintain more stable hormone levels and mitigate potential side effects like palpitations or anxiety, which can sometimes occur with a single large dose due to the rapid absorption of T3.The rationale behind splitting doses is to provide a more consistent supply of thyroid hormones to the body, smoothing out the peaks and troughs that might occur with a single daily dose.
This approach can be particularly beneficial for individuals who experience symptom fluctuations or who are more sensitive to hormonal changes.
Absorption Profiles and Formulation Timing Implications
The formulation of a thyroid medication can significantly impact its absorption kinetics, thereby influencing the optimal timing for administration.A comparative look at common formulations reveals:
- Levothyroxine Tablets: These are the most prevalent. Absorption is best on an empty stomach. Variability in dissolution rates between brands can occur, though most generic levothyroxine products are bioequivalent.
- Liquid Levothyroxine: This formulation may offer more consistent absorption for some individuals, particularly those with malabsorption issues or difficulty swallowing pills. It can still be taken on an empty stomach or at bedtime.
- Natural Desiccated Thyroid (NDT): Contains both T4 and T3. The presence of T3 necessitates careful consideration of dosing frequency to manage its faster absorption and shorter half-life.
- Liothyronine (Synthetic T3): If prescribed as a standalone medication, liothyronine has a very rapid onset and short duration of action. It is often taken in divided doses throughout the day to maintain therapeutic levels.
The physical form of the medication, such as tablets versus liquids, and the presence of excipients can all play a role. For instance, some individuals might find that certain tablet formulations cause gastrointestinal upset, leading them to explore alternative formulations or timing strategies.It is imperative for patients to discuss their specific medication, formulation, and any experienced side effects with their healthcare provider.
Adjustments to timing, dosage, or even formulation may be necessary to achieve optimal thyroid hormone replacement and symptom relief.
When to Seek Professional Guidance

Navigating thyroid medication, particularly its optimal timing, is a nuanced endeavor. While general guidelines offer a starting point, individual responses and specific medical conditions necessitate a personalized approach. This is where the expertise of a healthcare professional becomes paramount, ensuring your treatment plan remains safe, effective, and aligned with your unique health profile. Altering your medication schedule without proper consultation can lead to suboptimal treatment outcomes or, more critically, adverse health effects.The decision to adjust when you take your thyroid medication should never be made in isolation.
Your doctor or endocrinologist possesses the in-depth knowledge of your medical history, current health status, and the specific properties of your prescribed thyroid medication to guide you safely. They can assess potential interactions with other medications, consider your lifestyle, and monitor your thyroid hormone levels to determine the most appropriate timing for your individual needs.
Importance of Consulting a Healthcare Professional Before Altering Medication Schedules
The human body is a complex system, and introducing changes to medication timing can have cascading effects. Thyroid hormones play a crucial role in regulating metabolism, energy levels, and numerous bodily functions. Inconsistent absorption or fluctuating levels due to improper timing can disrupt these processes. A healthcare provider ensures that any proposed changes are based on scientific understanding and your specific physiological responses, thereby minimizing the risk of unintended consequences.
“Self-adjusting thyroid medication timing without medical supervision can undermine treatment efficacy and potentially lead to a worsening of symptoms or the development of new health issues.”
This statement underscores the critical need for professional oversight. Your doctor can evaluate the pharmacokinetic profile of your specific thyroid medication, which details how the drug is absorbed, distributed, metabolized, and excreted by the body. This understanding is vital for establishing an effective and consistent dosing schedule.
Signs and Symptoms Indicating a Need to Re-evaluate Thyroid Medication Timing
While some individuals may experience no discernible issues when adjusting their medication timing slightly, others might encounter subtle or overt signs that their current schedule is not optimal. Recognizing these indicators is the first step toward seeking the necessary professional advice. These signs often reflect a disruption in the stable thyroid hormone levels your body requires to function optimally.Pay close attention to the following symptoms, as they may suggest a need to discuss your medication timing with your doctor:

These symptoms are not exhaustive but represent common indicators that your thyroid hormone levels might be experiencing undue variability due to medication timing.
Communicating Concerns About Medication Effectiveness or Side Effects Related to Timing
When you decide to discuss your thyroid medication timing with your doctor, preparation can ensure a productive and informative consultation. Clearly articulating your concerns will help your healthcare provider understand your experience and offer the most relevant guidance. Before your appointment, it is beneficial to keep a log of your symptoms, noting when they occur in relation to your medication intake.When you speak with your doctor, consider the following points to effectively communicate your concerns:
- Describe your symptoms precisely: Instead of saying “I feel tired,” be more specific. For instance, “I experience profound fatigue between 2 PM and 4 PM daily, which is about 6-8 hours after taking my morning medication.”
- Detail your current medication schedule: Clearly state when you take your thyroid medication, along with any other medications or supplements you are taking, and at what times.
- Mention any recent changes: Have you recently changed your diet, sleep schedule, or introduced new supplements? These can sometimes interact with thyroid medication absorption.
- Discuss your lifestyle: Your daily routine, including meal times and exercise, can influence medication absorption.
- Express your expectations: Clearly state what you hope to achieve by adjusting your medication timing, such as improved energy or reduced symptom severity.
Your doctor will likely review your recent thyroid function tests (TSH, T3, T4) and may order new ones to assess your current hormone levels. They will also inquire about your overall health, other medical conditions, and any other medications you are taking. This comprehensive approach allows them to make an informed decision about whether adjusting your medication timing is appropriate and, if so, what the best schedule might be.
“Open and honest communication with your healthcare provider is the cornerstone of effective thyroid management.”
This principle is especially true when dealing with the intricacies of medication timing. By working collaboratively, you and your doctor can fine-tune your treatment plan to optimize your well-being.

Can taking thyroid medicine at night cause sleep issues?
Some people report feeling a bit wired or experiencing insomnia if they take their thyroid medication too close to bedtime, though this isn’t universal. It’s often about individual sensitivity and how your body processes the hormone overnight.
What if I accidentally take my thyroid medicine at night instead of the morning?
Don’t stress too much! For a single missed morning dose or an accidental nighttime dose, it’s usually okay. Just resume your normal schedule the next morning. However, if this becomes a pattern, it’s best to discuss it with your doctor to avoid potential impacts on your thyroid levels.
Are there any specific thyroid medications that are definitely not okay to take at night?
While generally, the advice is to take thyroid medication in the morning due to absorption, specific formulations or natural desiccated thyroid hormones might have slightly different considerations. Always check with your prescribing doctor or pharmacist for personalized advice on your specific medication.
Will taking my thyroid medicine at night affect my weight or energy levels differently than taking it in the morning?
The primary goal of thyroid medication is to regulate hormone levels, which indirectly impacts weight and energy. While the timing

Can I take my thyroid medicine at night if I have GERD or acid reflux?
GERD and acid reflux can significantly interfere with thyroid medication absorption, regardless of the time of day.
