Sleeping All Day: The Negative Impact On Your Health

what happens if you sleep all day

Sleeping all day is known as oversleeping or long sleeping. While the amount of sleep one needs varies from person to person, sleeping for an extended period of time is generally associated with several health risks and could indicate an underlying health condition. For example, people who sleep for nine or ten hours every night are 21% more likely to become obese over a six-year period than those who sleep between seven and eight hours. Oversleeping is also linked to an increased risk of heart disease and depression. If you find yourself sleeping all day, it may be beneficial to consult a healthcare professional to rule out any potential sleep disorders or underlying health issues.

Potential underlying health conditions

Oversleeping, or "long sleeping," is typically defined as regularly sleeping for more than nine hours per night. While the amount of sleep one needs can vary based on age, activity level, general health, and lifestyle habits, chronic oversleeping may be a symptom of exhaustion or a sign of an underlying health condition.

Sleep Disorders

There are over 80 types of sleep disorders, and they can significantly affect the quality and duration of sleep. Some common sleep disorders include:

  • Sleep apnea: A breathing disorder characterised by brief pauses in breathing during sleep.
  • Restless legs syndrome: A brain disorder causing an urge to move the legs while at rest.
  • Bruxism: Involuntary teeth grinding or clenching during sleep.
  • Narcolepsy: A condition where the brain can't control sleep and wakefulness, leading to sudden sleep attacks.
  • Hypersomnia: A group of conditions causing excessive daytime sleepiness, even after a full night's sleep. Kleine-Levin Syndrome (KLS) is a rare form of hypersomnia, where people sleep for 16 to 20 hours a day during an episode.

Mental Health Conditions

Mental health disorders can impact sleep patterns and contribute to oversleeping. These include:

  • Depression: About 15% of people with depression sleep too much, and the condition can sap energy levels, leading to increased sleep.
  • Anxiety: While often associated with insomnia, anxiety can also cause excessive sleepiness during the day as a result of disrupted nighttime sleep.

Physical Health Conditions

Several physical health issues can interfere with sleep quality and duration, including:

  • Hypothyroidism (underactive thyroid gland)
  • Oesophageal reflux
  • Nocturnal asthma
  • Chronic pain conditions
  • Obesity: Longer sleep durations are associated with a higher risk of obesity, even when factors like food intake and exercise are controlled.
  • Heart disease: Research suggests that women sleeping nine to 11 hours per night are more likely to develop coronary heart disease.

If you or someone you know is struggling with chronic oversleeping, it is important to consult a healthcare professional. They can help diagnose any underlying conditions and develop a treatment plan to improve sleep habits and overall well-being.

Obesity

Sleep plays a significant role in maintaining a healthy body weight. Sleep deprivation has been linked to an increased risk of becoming overweight or obese. Getting fewer than seven hours of sleep can lead to weight gain, either by increasing food intake or decreasing energy burned. Sleep loss creates a hormone imbalance in the body, promoting overeating and weight gain. Specifically, sleep deprivation decreases leptin levels, making you feel hungrier, while simultaneously increasing ghrelin levels, further enhancing feelings of hunger. This can lead to increased snacking and consumption of high-calorie, fatty, and carbohydrate-rich foods, resulting in weight gain.

The relationship between sleep and obesity operates in a bidirectional manner. Just as sleep loss contributes to weight gain, obesity can also cause sleep issues. Individuals with obesity experience more insomnia and sleep difficulties than those with normal weight. Obesity may alter metabolism and sleep-wake cycles, known as circadian cycles, leading to sleep quality deterioration. The physical effects of carrying excess weight can also impact sleep, increasing the risk of sleep disorders such as obstructive sleep apnea (OSA). Excess fat can put pressure on airways, making breathing difficult, especially when lying down.

The cycle of sleep loss and weight gain can be challenging to break. However, addressing sleep issues and improving sleep quality can be beneficial in managing weight. Maintaining proper sleep hygiene is essential, which includes adhering to a consistent sleep schedule, creating a bedtime routine, and engaging in healthy habits during the day. Incorporating physical activity into your daily routine can also promote better sleep and contribute to weight management.

Additionally, it is important to pay attention to your diet and make conscious food choices. Limiting junk food and opting for healthy snacks can help reduce binge eating and the intake of high-calorie foods. Managing stress through techniques such as journaling, meditation, and deep breathing can also positively impact sleep and overall well-being. Seeking guidance from a doctor or sleep specialist can be beneficial in addressing sleep concerns related to weight.

In summary, the link between sleep and obesity is complex and multifaceted. Sleep loss can lead to weight gain through hormonal imbalances and increased food intake, while obesity can disrupt sleep quality and contribute to sleep disorders. Breaking the cycle requires a comprehensive approach that includes improving sleep hygiene, engaging in physical activity, making healthy food choices, and managing stress. By addressing both sleep and weight management, individuals can improve their overall health and well-being.

Headaches

Oversleeping can cause headaches, and it is one of the most common reasons for them. While the reasons are not always clear, researchers have found several links between oversleeping and headaches. One theory suggests that oversleeping impacts certain neurotransmitters in the brain, including serotonin. Another theory suggests that it is due to interruptions in the natural sleep cycle.

Hypnic headaches are a rare type of headache that develops while sleeping, waking people up with a dull, throbbing pain at the same time every night. They occur during REM sleep and are believed to be caused by a disruption to the circadian rhythm. They are more common in people over 50, but can affect anyone, including children.

If you are experiencing frequent headaches, it is recommended to maintain a consistent sleep schedule, avoid blue light before bed, and create a relaxing bedtime routine. If headaches persist, it may be advisable to consult a healthcare professional to rule out any underlying conditions.

Depression

Sleep and depression are closely linked. Poor sleep can negatively impact mental health and increase the risk of depression, while depression can cause sleep difficulties, creating a cycle that can be challenging to break.

Sleep difficulties are a core symptom of depression. Insomnia, the inability to fall asleep or maintain sleep, is a common sleep issue associated with depression. It can lead to daytime fatigue, concentration problems, and increased risk of accidents. Hypersomnia, or excessive sleepiness, is another sleep disorder linked to atypical depression. This subtype of depression may manifest as sleeping and eating too much, and it can be harder to identify as it may not involve classic depressive symptoms. Those with hypersomnia may sleep as much as 14 to 18 hours a day.

The relationship between sleep and depression is complex and bidirectional. On the one hand, sleep issues can be a risk factor for developing depression. On the other hand, depression can cause sleep problems, with many individuals experiencing both insomnia and hypersomnia during a depressive episode. Additionally, the quality of sleep matters; interrupted sleep can interfere with restorative slow-wave sleep, leading to a reduction in positive moods the following day.

Treating sleep disorders and improving sleep quality can help manage depression. Exercise, sunlight exposure, and cognitive behavioural therapy (CBT) are some strategies to enhance sleep and mental health. While treatments for depression can improve mood and outlook, they may not be sufficient to resolve sleep issues. Therefore, addressing both the depression and sleep problems is crucial for effective management.

Hypersomnia

The main symptom of hypersomnia is excessive daytime sleepiness, which has occurred for at least three months prior to diagnosis. People with hypersomnia may also experience "sleep drunkenness", a difficulty transitioning from sleep to wakefulness. This can manifest as confusion, disorientation, slowness, and repeated returns to sleep. Sleep drunkenness also appears in non-hypersomniacs after a night of insufficient sleep or as a result of fatigue or alcohol consumption.

Secondary hypersomnia can be caused by various medical conditions, including clinical depression, multiple sclerosis, encephalitis, epilepsy, obesity, and sleep apnea. It can also be caused by certain medications, withdrawal from medications, or substance use, such as alcohol or recreational drugs.

If you suspect you may have hypersomnia, it is important to consult a healthcare professional. They can help provide a proper diagnosis and develop a treatment plan, which may include medications, changes to sleep habits, and therapy.
