Fighting Fatigue: Sleeping All Day, Still Tired

Feeling sleepy during the day can be a symptom of hypersomnia, a condition characterised by excessive sleepiness and the inability to stay awake and alert during the day, despite getting adequate sleep at night. Hypersomnia can be caused by a variety of factors, including sleep disorders, medications, and medical or psychiatric illnesses. It can also be a result of lifestyle factors such as shift work, family demands, and social life. If you are experiencing hypersomnia, it is important to seek advice from a doctor or a sleep disorder clinic as it can be treated with medication or lifestyle adjustments.

Hypersomnia, a condition characterised by excessive sleepiness during the day

Hypersomnia is a condition characterised by excessive sleepiness during the day. It is a neurological disorder that affects a person's ability to stay awake and alert during the day, despite getting more than enough sleep at night. People with hypersomnia may sleep for long hours at night and still feel the need to nap during the day. These daytime naps are often unrefreshing and nonrestorative, and individuals may experience "sleep drunkenness", or difficulty transitioning from sleep to wakefulness.

The main symptom of hypersomnia is excessive daytime sleepiness (EDS), which has occurred for at least 3 months prior to diagnosis. Other symptoms include:

• Regular napping during the day
• Sleeping longer than average (10 or more hours) and still feeling sleepy
• "Sleep drunkenness", or difficulty waking up in the morning or after daytime naps, sometimes with confusion or irritability
• Daytime naps do not lead to improved alertness
• Anxiety and irritability
• Slow thinking, slow speech, difficulty concentrating, and memory problems

Hypersomnia can have a significant impact on a person's quality of life, affecting their ability to function at work and socially, and increasing the risk of accidents, especially vehicle accidents. It is more common in females and is usually diagnosed in adolescence or young adulthood (average age 17 to 24 years).

The exact cause of hypersomnia is often unknown, but it can be primary (of central/brain origin) or secondary to another medical condition. Secondary hypersomnia can be caused by various medical conditions, medications, alcohol or substance use, genetic predispositions, or physical problems such as a tumour or head trauma. Primary hypersomnias include narcolepsy, idiopathic hypersomnia, and recurrent hypersomnias like Kleine-Levin syndrome.

Treatment for hypersomnia depends on the underlying cause and may include medications or lifestyle changes. Medications used to promote wakefulness include modafinil, armodafinil, and psychostimulants like amphetamine and methylphenidate. Lifestyle changes may involve improving sleep hygiene, such as maintaining a regular sleeping schedule, creating a comfortable and peaceful sleeping environment, limiting caffeine and alcohol, and avoiding working late into the night.

Sleep disorders, such as sleep apnea, restless leg syndrome, and insomnia

Feeling tired despite sleeping all day could be due to a variety of factors, including sleep disorders such as sleep apnea, restless leg syndrome, and insomnia.

Sleep apnea is a condition where your breathing repeatedly stops and starts during sleep, disrupting your sleep quality. It is often associated with obesity and can lead to daytime fatigue. Obstructive sleep apnea is a common form of the condition, and maintaining a healthy body weight can help manage it.

Restless leg syndrome (RLS) is a movement disorder causing an irresistible urge to move your legs while resting, along with uncomfortable sensations like itching, pulling, or throbbing. RLS can affect your ability to fall asleep and cause fatigue during the day. While there is no cure, treatments such as iron supplements, antiseizure medications, and dopamine agonists can help manage symptoms.

Insomnia is a condition that causes difficulty falling or staying asleep. It can be triggered by various factors, including menopause, medical conditions, psychological stress, poor sleeping environments, and excessive mental stimulation. Treatments for insomnia may include natural supplements, medications, and addressing underlying medical conditions.

If you are experiencing persistent fatigue, it is important to consult a healthcare professional to identify any underlying causes and determine an appropriate treatment plan.

Lifestyle factors, including diet, exercise, and shift work

Diet:

The foods and drinks you consume can affect your sleep quality and energy levels. A diet rich in nutrient-dense foods like fruits, vegetables, legumes, and healthy protein sources can reduce fatigue and promote healthy sleep. Ultra-processed foods and added sugars can impair energy levels and disrupt sleep. Caffeine, a stimulant commonly found in coffee and energy drinks, can disrupt your sleep cycles, leading to fatigue. While moderate caffeine consumption is generally fine, excessive intake can lead to sleep issues and increased fatigue. It is recommended to limit caffeine intake, especially in the evening, to improve sleep and reduce tiredness. Additionally, staying hydrated is crucial for maintaining energy levels. Dehydration can lead to lower energy and decreased concentration, so ensuring adequate fluid intake is essential.

Exercise:

Regular exercise is beneficial for improving sleep quality and reducing fatigue. Both aerobic exercises, such as cardio and running, and resistance exercises, such as weightlifting, can enhance sleep quality. Any amount of movement or physical activity can be beneficial, with younger individuals typically requiring more exercise than older adults to achieve similar benefits. However, the timing of exercise is also important. Exercising too close to bedtime may interfere with sleep for some people due to increased endorphin levels and elevated body temperature, which can make it challenging to fall asleep. Therefore, it is recommended to exercise earlier in the day, allowing enough time for the body to wind down before bed.

Shift Work:

Shift work, or working outside the traditional daytime hours, can cause sleep disruption and lead to fatigue. This disruption may be due to the misalignment between your work schedule and your body's natural sleep-wake cycles, resulting in insufficient or poor-quality sleep. If you work shifts, prioritising sleep and creating a conducive sleep environment are crucial. Maintaining a consistent sleep schedule, even on days off, can help regulate your body clock and improve sleep quality. Additionally, practising good sleep hygiene, such as limiting caffeine and electronic device usage before bed, can enhance sleep.

Medical conditions, like hypothyroidism, diabetes, and congestive heart failure

If you're sleeping all day and still feel tired, it could be a sign of an underlying medical condition. While there are many potential causes of chronic fatigue, some medical conditions are known to cause or contribute to it. These include:

Hypothyroidism

An underactive thyroid gland can disrupt sleep and cause daytime sleepiness. This is a common cause of secondary hypersomnia, a condition characterised by excessive daytime sleepiness.

Diabetes

Living with diabetes can impact your energy levels and cause fatigue. Managing blood sugar levels through diet and medication can help reduce fatigue.

Congestive Heart Failure

This condition can affect your sleep quality and leave you feeling tired during the day. It's important to manage congestive heart failure with the help of a healthcare professional and make any necessary lifestyle changes.

Other medical conditions that can cause fatigue include:

• Chronic kidney disease
• Chronic obstructive pulmonary disease (COPD)
• Multiple sclerosis (MS)
• Rheumatoid arthritis (RA)
• Chronic fatigue syndrome
• Obstructive sleep apnea
• Depression
• Anxiety
• Bipolar disorder
• Seasonal depression
• Head trauma
• Tumours
• Central nervous system diseases
• Obesity
• Alzheimer's disease
• Ulcerative colitis
• Crohn's disease
• Geographic atrophy
• Bipolar disorder
• Menopause
• Poor sleeping environments
• Excessive mental stimulation

If you're experiencing chronic fatigue, it's important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.

Mental health, including stress, anxiety, and depression

Mental Health

Mental health issues such as stress, anxiety, and depression are closely linked to sleep problems. Sleep difficulties can be both a cause and a symptom of mental health issues.

Stress

Chronic stress can lead to structural and functional changes in the brain, causing chronic inflammation and contributing to fatigue. It can also affect sleep by making the body aroused, awake, and alert, leading to sleep problems. Addressing stress through therapy or other means can help improve sleep.

Anxiety

Anxiety disorders are often associated with sleep difficulties. Anxiety increases agitation and arousal, making it challenging to fall asleep and maintain restful sleep. Studies have found that people with insomnia are more likely to develop anxiety disorders. Addressing anxiety through treatment or therapy can help improve sleep quality.

Depression

Depression and sleep problems have a bidirectional relationship, meaning that they influence each other. People with insomnia have an increased risk of developing depression, and those with depression often experience sleep difficulties. Depression is associated with a reduction in restorative slow-wave sleep, which can further impact mood and emotional regulation. Treating sleep problems can help alleviate depressive symptoms, and addressing depression through therapy or medication can improve sleep quality.

In summary, mental health issues such as stress, anxiety, and depression are closely tied to sleep. They can contribute to sleep disturbances, and sleep problems can, in turn, exacerbate or trigger the onset of these mental health conditions. Addressing mental health concerns and improving sleep habits can help alleviate symptoms and improve overall well-being.
