Ever feel like you could sleep for days, but wonder why you suddenly find yourself snoozing longer than a hibernating bear? In this blog, we uncover why you might be hitting the snooze button more often than usual, and discover some simple yet effective ways to bounce back into your lively, well-rested self!

Let’s dive in!

11 Reasons For Excessive Sleepiness

Here are 11 detailed reasons why you might be sleeping too much all of a sudden:

1. Changes in Routine

Changes in your daily schedule, such as starting a new job with different hours or adjusting to a new semester at school, can disrupt your sleep patterns. Your body may need time to adapt to the new schedule, leading to excessive sleepiness.

2. Stress or Anxiety

Stress and anxiety can have a profound impact on sleep. When you’re stressed or anxious, your body may produce more cortisol, a hormone that can interfere with your ability to fall asleep and stay asleep. Additionally, racing thoughts and worries can keep you awake at night, leading to daytime fatigue and a desire to sleep more.

3. Depression

Depression often manifests as changes in sleep patterns, with some people experiencing hypersomnia, or excessive sleepiness. Feelings of sadness, hopelessness, and low energy can make it difficult to get out of bed in the morning and lead to prolonged periods of sleep.

4. Sleep Disorders

Sleep disorders such as sleep apnea, narcolepsy, and restless legs syndrome can disrupt your sleep and cause excessive daytime sleepiness. These conditions often go undiagnosed, so it's important to consult a healthcare professional if you suspect you may have a sleep disorder.

5. Medications

Certain medications, including antidepressants, antihistamines, and muscle relaxants, can cause drowsiness as a side effect. If you’ve recently started taking a new medication and noticed an increase in sleepiness, it may be worth discussing with your doctor.

6. Medical Conditions

Underlying medical conditions such as hypothyroidism, anemia, and fibromyalgia can cause fatigue and excessive sleepiness. If you’re experiencing other symptoms in addition to increased sleepiness, see a healthcare professional for a proper evaluation.

7. Poor Sleep Hygiene

Sleep hygiene refers to a set of practices that promote healthy sleep, such as maintaining a consistent sleep schedule, creating a comfortable sleep environment, and avoiding stimulants like caffeine and electronic devices before bedtime. Poor sleep hygiene can lead to difficulty falling asleep and staying asleep, resulting in excessive daytime sleepiness.

8. Substance Abuse

Excessive alcohol consumption or drug use can disrupt your sleep patterns and lead to increased sleepiness during the day. Alcohol may help you fall asleep initially, but it can interfere with the quality of your sleep and lead to waking up feeling unrefreshed.

9. Lack of Physical Activity

Regular physical activity is crucial for maintaining healthy sleep patterns. If you’re not getting enough exercise during the day, you may have difficulty falling asleep at night and feel more tired during the day.

10. Poor Diet

The relationship between nutrition and sleep is such that a diet high in processed foods, sugar, and caffeine can negatively impact your sleep quality. Consuming these foods close to bedtime can interfere with your ability to fall asleep and stay asleep, leading to daytime fatigue.

11. Age-related Changes

As we age, our sleep patterns often change. Older adults may experience lighter sleep, more frequent awakenings during the night, and increased daytime sleepiness. Additionally, older adults may need more sleep than younger adults to feel rested due to age-related changes in sleep architecture.

It’s essential to consider these factors and consult with a healthcare professional if you’re experiencing persistent excessive sleepiness to rule out any underlying medical conditions and receive appropriate treatment.

Next, let’s look at things you can try to tackle excessive sleepiness from the comfort of your home!

How to Address Sudden Excessive Sleepiness

How to Address Sudden Excessive Sleepiness

Here are several strategies you can try:

1. Evaluate Your Sleep Routine: Assess your current sleep habits, including your bedtime routine, sleep environment, and sleep schedule. Aim for 7-9 hours of quality sleep per night and try to maintain a consistent sleep-wake schedule, even on weekends.

2. Improve Sleep Hygiene: Practice good sleep hygiene by creating a comfortable sleep environment that is cool, dark, and quiet. Limit exposure to screens (phones, computers, TVs) before bedtime and avoid caffeine and heavy meals close to bedtime.

3. Manage Stress and Anxiety: Practice relaxation techniques such as deep breathing, meditation, or progressive muscle relaxation to help reduce stress and promote better sleep. Consider using calming sleep aids like our Cotton weighted blanket, the Napper, whose gentle weight reduces the production of Cortisol, the stress hormone.

4. Limit Napping: While short naps can be beneficial, excessive daytime napping can disrupt your sleep-wake cycle and contribute to feeling more tired. Limit naps to 20-30 minutes earlier in the day if you feel the need to nap.

5. Stay Active: Engage in regular physical activity during the day, but avoid vigorous exercise close to bedtime as it can interfere with sleep. Aim for at least 30 minutes of moderate exercise most days of the week.

6. Evaluate Medications: If you suspect that a medication you’re taking is causing excessive sleepiness, discuss your concerns with your healthcare provider. They may be able to adjust your dosage or switch you to a different medication with fewer sedating effects.

7. Address Underlying Medical Conditions: If you suspect an underlying medical condition such as sleep apnea, depression, or thyroid disorder is contributing to your excessive sleepiness, seek medical evaluation and treatment from a healthcare professional.

8. Limit Alcohol and Stimulants: Reduce or eliminate alcohol and stimulant intake, such as caffeine and nicotine, particularly in the hours leading up to bedtime. These substances can disrupt your sleep and contribute to daytime sleepiness.

9. Practice Mindfulness: Mindfulness practices, such as yoga or tai chi, can help improve sleep quality and reduce daytime sleepiness by promoting relaxation and stress reduction.

10. Seek Exposure to Natural Light: Exposure to natural light during the day can help regulate your sleep-wake cycle and improve daytime alertness. Spend time outdoors during daylight hours or consider using a light therapy box if natural light exposure is limited.

11. Consider Cognitive Behavioral Therapy for Insomnia (CBT-I): CBT-I is a structured program that helps address underlying issues contributing to insomnia and other sleep disturbances. It focuses on changing thoughts and behaviors related to sleep and can be highly effective in improving sleep quality and reducing daytime sleepiness.

12. Stay Hydrated: Dehydration can contribute to feelings of fatigue and sleepiness. Make sure you're drinking enough water throughout the day to stay hydrated and alert.

13. Take Breaks During the Day: If you’re feeling excessively sleepy during the day, take short breaks to stretch, walk around, or engage in activities that help you stay alert. Avoid prolonged periods of sitting or inactivity.

14. Limit Exposure to Blue Light at Night: Blue light from screens can interfere with your body’s natural sleep-wake cycle by suppressing the production of melatonin, a hormone that regulates sleep. Use blue light filters on electronic devices or consider wearing blue light-blocking glasses in the evening to minimize exposure.

If you’ve tried these strategies and are still experiencing excessive sleepiness, seek advice from a healthcare professional. This is because sudden excessive sleepiness can have great consequences on your health. Let’s talk about this more in the next section!

The Impact of Sudden Increase in Sleep Duration on Health

A sudden increase in sleep duration can have various impacts on health, both positive and negative. Here’s how:

1. Cognitive Function:

Positive Impact: Adequate sleep is crucial for cognitive function, including memory, concentration, and decision-making. A sudden increase in sleep duration may enhance cognitive performance by allowing the brain to consolidate memories and process information more effectively.

Negative Impact: However, excessive sleepiness or oversleeping can lead to cognitive impairment, including difficulty concentrating, memory problems, and slower reaction times. This can negatively impact daily activities and overall cognitive function.

2. Mood and Mental Health:

Positive Impact: Quality sleep is essential for emotional well-being, and a sudden increase in sleep duration may improve mood and reduce feelings of stress, anxiety, and irritability. Adequate sleep can also help regulate emotions and contribute to a more positive outlook on life.

Negative Impact: On the other hand, oversleeping has been associated with an increased risk of depression and other mood disorders. While it's not clear whether oversleeping causes depression or is a symptom of it, excessive sleepiness can worsen depressive symptoms and impair overall mental health.

3. Physical Health:

Positive Impact: Adequate sleep plays a vital role in supporting physical health and immune function. A sudden increase in sleep duration may enhance immune function, reduce inflammation, and promote overall well-being. It can also support the body's ability to repair and regenerate tissues, leading to improved recovery from illness or injury.

Negative Impact: However, excessive sleepiness or oversleeping has been linked to various negative health outcomes, including obesity, diabetes, cardiovascular disease, and mortality. Oversleeping may disrupt metabolic processes, lead to weight gain, and increase the risk of developing chronic health conditions.

4. Energy Levels and Fatigue:

Positive Impact: Getting enough sleep can increase energy levels, reduce fatigue, and improve overall physical stamina. A sudden increase in sleep duration may help replenish energy stores, enhance alertness, and promote a more active lifestyle.

Negative Impact: Paradoxically, oversleeping can lead to feelings of grogginess, lethargy, and persistent fatigue. Excessive sleepiness may interfere with daytime functioning, decrease motivation, and impair physical performance.

5. Hormonal Balance:

Positive Impact: Adequate sleep is essential for maintaining hormonal balance, including hormones that regulate appetite, metabolism, stress response, and reproductive function. A sudden increase in sleep duration may help restore hormonal equilibrium and support overall health and well-being.

Negative Impact: However, oversleeping can disrupt hormonal rhythms and lead to dysregulation of hormone production and secretion. This can have various negative effects on metabolism, appetite control, and reproductive health.

6. Quality of Life:

Positive Impact: Quality sleep is closely linked to overall quality of life, and a sudden increase in sleep duration may improve various aspects of well-being, including physical health, mental health, social functioning, and productivity. Adequate sleep can enhance resilience, improve coping skills, and promote a more fulfilling and satisfying life.

Negative Impact: Conversely, oversleeping can negatively impact quality of life by contributing to daytime dysfunction, social withdrawal, and reduced productivity. Excessive sleepiness may impair social relationships, limit participation in activities, and decrease overall life satisfaction.

Overall, while a sudden increase in sleep duration may have some positive effects on health, it’s essential to strike a balance and avoid excessive sleepiness or oversleeping, which can lead to various negative health outcomes.

Next, let’s look at some tell-tale signs that you should speak to a medical professional about the excessive sleepiness you’re experiencing.

 Impact of Sudden Increase in Sleep Duration on Health

When To See A Doctor

Here are some signs and symptoms that may indicate it's time to seek medical advice:

1. Persistent Changes in Sleep Patterns: If you’ve noticed a sudden and persistent increase in the amount of time you're sleeping, especially if it’s significantly more than your usual sleep duration, discuss this with a doctor.

2. Excessive Daytime Sleepiness: If you’re constantly feeling excessively sleepy during the day, despite getting what you believe to be sufficient sleep at night, it could be a sign of an underlying sleep disorder or other health issue that requires evaluation.

3. Difficulty Functioning: If your increased sleep duration is interfering with your ability to function normally during the day, impacting your work, school, relationships, or daily activities, seek medical attention.

4. Mood Changes: Changes in sleep patterns can often affect mood, and if you’re experiencing mood swings, irritability, depression, or anxiety along with changes in sleep duration, discuss these symptoms with a healthcare professional.

5. Other Symptoms: If you’re experiencing other symptoms along with changes in sleep patterns, such as headaches, weight changes, changes in appetite, or difficulty concentrating, it may indicate an underlying medical condition that requires evaluation.

6. Medication Side Effects: If you suspect that a medication you’re taking may be causing changes in your sleep patterns, such as excessive sleepiness or oversleeping, bring these concerns up with your doctor.

7. Chronic Health Conditions: If you have pre-existing medical conditions such as depression, anxiety, sleep apnea, or thyroid disorders, changes in sleep patterns may be a sign that your condition is not well-managed and requires adjustment to your treatment plan.


Feeling excessively sleepy all of a sudden can disrupt your life and affect your well-being. By understanding the reasons behind it, implementing strategies to address it, and knowing when to seek medical advice, you can regain control over your sleep patterns and improve your overall health and quality of life.
