Daytime Sleep: What Your Body Is Telling You

what happens when you sleep a lot during the day

Sleeping a lot during the day can be a symptom of hypersomnia, a condition characterized by excessive sleepiness during the day, even after a full night's rest. People with hypersomnia may experience difficulty staying awake during the day and may fall asleep repeatedly. This condition can be primary, occurring without an underlying cause, or secondary, resulting from other factors such as substance use, health conditions, or insufficient sleep. While occasional oversleeping is not uncommon, consistently sleeping more than nine hours is considered oversleeping and may indicate underlying health issues such as depression, sleep disorders, or chronic illnesses. It can also increase the risk for certain health problems, including diabetes, obesity, and heart disease. If you are concerned about sleeping a lot during the day, it is recommended to consult a healthcare professional and make necessary lifestyle changes to improve sleep hygiene and regulate sleep.

Potential causes: sleep deprivation, medication, alcohol, drugs, or underlying health issues

Oversleeping and excessive daytime sleepiness can be caused by a variety of factors, including sleep deprivation, medication, alcohol, drugs, or underlying health issues.

Sleep deprivation

Sleep deprivation occurs when an individual does not get enough sleep at night, leading to a build-up of sleep debt. This can cause individuals to sleep longer than usual to compensate for the lost sleep. Temporary oversleeping can be a result of recovering from sleep deprivation. However, consistently sleeping longer than the recommended seven to nine hours for adults can indicate chronic sleep deprivation and lead to negative health consequences.

Medication

Certain medications can cause oversleeping due to their sedating effects or drowsiness as side effects. If you suspect that your medication is causing you to sleep too much, it is important to consult a healthcare professional. They can advise on modifying your treatment plan or provide alternative options.

Alcohol and drugs

Alcohol consumption can affect sleep patterns and contribute to excessive daytime sleepiness. It has sedating effects, making individuals feel drowsy and sleepy. Additionally, the use of recreational drugs, such as cannabis or opiates, can impact sleep and lead to hypersomnia. Stopping the use of stimulating illegal drugs, such as amphetamines or cocaine, can also result in a period of excessive sleepiness.

Underlying health issues

Chronic oversleeping may be a symptom of underlying health issues, including mental and physical conditions. Mental health conditions such as depression, anxiety, and chronic pain can contribute to sleepiness and hypersomnia. Physical health conditions like diabetes, fibromyalgia, and hypothyroidism can also make it challenging for individuals to stay awake for extended periods. Additionally, sleeping too much has been linked to an increased risk of obesity, heart disease, and mortality rates.

Side effects: headaches, low energy, and increased risk of diabetes and obesity

Oversleeping, or long sleeping, is typically defined as sleeping for more than nine hours in a 24-hour period. While occasional oversleeping is not usually a cause for concern, consistent oversleeping can be linked to underlying health issues, such as depression, anxiety, sleep disorders, or chronic illnesses. It can also lead to daytime grogginess and low energy.

Headaches

For some people prone to headaches, sleeping longer than usual can trigger head pain. Researchers believe this is due to the effect oversleeping has on certain neurotransmitters in the brain, including serotonin. People who sleep too much during the day and disrupt their nighttime sleep may also experience headaches in the morning.

Low Energy

Oversleeping can cause daytime grogginess and low energy. This can lead to feelings of fatigue and a lack of motivation throughout the day. It can also impact an individual's ability to concentrate and perform tasks effectively.

Increased Risk of Diabetes and Obesity

Studies have shown that sleeping too long or not enough each night can increase the risk of diabetes. Additionally, sleeping too much or too little has been linked to weight gain and a higher risk of obesity. One study found that individuals who slept for nine or ten hours every night were 21% more likely to become obese over a six-year period compared to those who slept between seven and eight hours.

Hypersomnia: a condition characterised by excessive daytime sleepiness

Hypersomnia is a condition characterised by excessive daytime sleepiness. People with hypersomnia experience extreme sleepiness during the day, even after getting a full night's rest. This can make it difficult or impossible to stay awake, impacting an individual's work and social life. Hypersomnia can be caused by various factors, including primary and secondary influences.

Primary hypersomnia occurs without any known cause or underlying condition. The most common type is idiopathic hypersomnia, where individuals sleep for long periods and wake up feeling confused, irritable, and unrefreshed. There is also Kleine-Levin syndrome (KLS), a rare condition that causes people to sleep for 16 to 20 hours a day during an episode. Lastly, narcolepsy is a type of primary hypersomnia where the brain cannot control sleep and wakefulness.

Secondary hypersomnia, on the other hand, is triggered by another health condition, substance use, or insufficient sleep. Health conditions affecting the muscles, brain, or central nervous system can cause secondary hypersomnia. Mental health disorders, such as depression, anxiety, and chronic pain, are also associated with this type of hypersomnia. Additionally, substances like alcohol, cannabis, opiates, and certain medications can contribute to secondary hypersomnia.

The treatment for hypersomnia depends on the underlying cause. It may include medications to promote wakefulness, changes to sleep habits, and therapy. Lifestyle changes, such as maintaining a consistent sleep schedule, avoiding caffeine and alcohol close to bedtime, and improving sleep hygiene, can also help manage hypersomnia. However, changing sleep habits may not be a cure, but it can improve overall well-being.

If you suspect you may have hypersomnia, it is important to consult a healthcare professional. They can help determine the underlying cause and provide appropriate treatment options. Keeping a sleep diary before your appointment can also aid in diagnosing the condition and understanding your sleep patterns. Hypersomnia can significantly impact daily functioning, and seeking professional help is essential for managing the condition effectively.

Treatment: medication, therapy, and improving sleep habits

Treatment for hypersomnia, a condition that makes you feel extremely sleepy during the day, includes medication, therapy, and improving sleep habits.

Medication

Medications can help you stay awake during the day. Your healthcare provider will suggest the right kind of medicine based on the type of hypersomnia you have. For example, if your hypersomnia is caused by side effects from other medications, your doctor may change or adjust your dosage of those medications.

Therapy

Therapy can be an effective treatment for hypersomnia, especially if it is caused by or accompanied by mental health issues such as anxiety, stress, or depression. Cognitive-behavioral therapy (CBT) is a common type of therapy that can help you manage your sleep habits and address any underlying thoughts and behaviors that may be contributing to your sleepiness during the day.

Improving Sleep Habits

Improving your sleep habits, also known as sleep hygiene, can be an important part of treating hypersomnia. This includes establishing a consistent bedtime routine and sleep environment, avoiding alcohol and caffeine, and refraining from exercising a few hours before bedtime. Keeping a sleep journal or using an actigraphy sensor, a device that looks like a smartwatch, can help you and your healthcare provider track your sleep patterns and identify any disruptions in your sleep-wake cycle.

When to seek help: if you regularly sleep for 12 hours, keep a sleep diary, and consult a doctor

If you're regularly sleeping for 12 hours and still feel tired, it's important to consult a doctor. Sleeping for 12 hours is above the National Sleep Foundation's recommendations for people ages 6 years and older. While occasional oversleeping may be due to recovering from a period of intense physical activity or short sleep duration, chronic oversleeping may indicate an underlying health condition.

Before seeking medical advice, it's recommended to record your sleeping habits in a sleep diary. This will help the doctor understand your sleeping patterns and make a proper diagnosis. They may also ask you to wear a wrist actigraph to monitor your sleep-wake cycles.

When you visit the doctor, they will likely ask questions about your medical history and perform a physical examination. They may also recommend a sleep study to test for conditions such as sleep apnea, which is a breathing disorder that causes brief pauses in breathing during sleep.

Treatment for oversleeping will depend on the underlying cause. If an underlying health issue is the cause, treating it may help regulate your sleep. Your treatment plan may include a combination of lifestyle changes, at-home remedies, and medications.

It's important to address chronic oversleeping as it has been associated with an increased risk of several health conditions, including type 2 diabetes, stroke, sleep apnea, idiopathic hypersomnia, and more. Additionally, frequent oversleeping may indicate hypersomnia, a condition characterized by excessive daytime sleepiness, even after a full night's rest.
