Feeling sleepy all the time can be a symptom of hypersomnia, a group of conditions that cause extreme daytime sleepiness. Hypersomniacs may sleep for 11 hours or more at night but still feel the need to nap during the day. Other causes of excessive sleepiness include poor sleep quality, pain, mental and physical health problems, medication, lifestyle habits, and sleep disorders such as sleep apnea, restless leg syndrome, insomnia, and narcolepsy. If you feel tired all the time, it's important to talk to a healthcare provider to rule out any underlying conditions and make any necessary lifestyle adjustments to improve your sleep quality.

What You'll Learn
Hypersomnia and its causes
Hypersomnia is a condition that makes people feel extremely sleepy during the day, even after a full night's rest. People with hypersomnia may fall asleep several times during the day without intending to. This can interfere with their daily lives, affecting their work, education, and personal relationships. It can also increase the risk of accidents and injuries.
There are two main types of hypersomnia: idiopathic hypersomnia and secondary hypersomnia. Idiopathic hypersomnia, the most common type, occurs without any known cause. People with this type of hypersomnia experience excessive night-time sleeping and a need for daytime naps. They may sleep for 11 hours or more but still feel sleepy during the day, and napping may not make them feel more alert or rested. Kleine-Levin syndrome (KLS) is a rare form of idiopathic hypersomnia, where people sleep for 16 to 20 hours a day during an episode.
Secondary hypersomnia, on the other hand, is caused by an underlying health condition or other factors. These factors can include alcohol or recreational drug use, certain medications, physical health issues, mental health conditions, or injuries such as head trauma. Shift work, family demands, study, and social life can also contribute to secondary hypersomnia by disrupting sleep patterns.
In addition to these specific causes, hypersomnia can also be related to poor sleep quality or insufficient sleep. This can be due to pain, sleep disorders such as sleep apnea, or interruptions during sleep caused by light, noise, or other disturbances.
The treatment for hypersomnia depends on the underlying cause and may involve lifestyle adjustments, medication, changing sleep habits, or therapy. While there is currently no cure for hypersomnia, managing the condition can reduce its impact on daily life.

Sleep disorders and treatments
Sleep is essential for our well-being, and when our sleep patterns are disrupted, it can have a significant impact on our lives. Sleep disorders can affect our energy levels, mood, concentration, and overall health. They can also impair our ability to perform daily activities, cause issues at work, and strain personal relationships.
There are several sleep disorders that can cause excessive sleepiness during the day, even after a full night's rest. One such disorder is hypersomnia, which includes conditions like narcolepsy and idiopathic hypersomnia. People with hypersomnia may sleep for extended periods, such as 11 hours or more, yet still feel the need to nap throughout the day. They may fall asleep suddenly and unintentionally, even while engaged in activities that require concentration, such as driving or operating machinery, leading to a higher risk of accidents and injuries.
Another common sleep disorder is insomnia, which makes it difficult to fall asleep or stay asleep for a satisfying duration. This can lead to excessive sleepiness during the day, impacting an individual's productivity and mood. Obstructive Sleep Apnea (OSA) is a breathing disorder that causes brief pauses in breathing during sleep, resulting in fragmented sleep and daytime drowsiness. Restless Leg Syndrome (RLS) is a condition that creates a compelling urge to move the legs, disrupting total sleep time and quality.
Circadian rhythm sleep-wake disorders occur when an individual's sleep schedule is misaligned with their body's internal clock and the local day-night cycle. This can be a problem for shift workers or those experiencing jet lag. Mental health issues, such as anxiety and depression, can also contribute to sleep disorders, with anxiety causing sleepless nights and depression sapping energy levels.
The treatment for sleep disorders depends on the specific disorder and its underlying causes. It often involves a combination of medical treatments and lifestyle changes. Continuous Positive Airway Pressure (CPAP) therapy and orofacial therapy are recommended for sleep apnea, while Cognitive Behavioral Therapy for Insomnia (CBT-I) is a common treatment for insomnia. Medications, such as melatonin receptor agonists and orexin receptor antagonists, may be prescribed for insomnia or narcolepsy, respectively, but these should be discussed with a healthcare provider due to potential side effects.
Lifestyle adjustments, often referred to as good "sleep hygiene," can significantly improve sleep quality. This includes maintaining a regular sleep schedule, sleeping in a cool, quiet, and dark environment, and avoiding electronic devices before bed. Other recommendations include exercising regularly, maintaining a balanced diet, and reducing the consumption of substances like cigarettes, alcohol, and caffeinated drinks, especially close to bedtime.

Lifestyle habits and their impact
Excessive daytime sleepiness (EDS) or hypersomnia is not a condition in itself but a symptom caused by an underlying problem or a combination of factors. It is important to discuss your current medications and potential side effects with your doctor. They can offer guidance on timing and dosage of your medications and make adjustments as needed. Do not make any changes to your medication without consulting your doctor.
Shift work can make it very difficult to get good sleep, especially night shifts. This is due to the effect of being out of sync with the body's internal clock (the circadian rhythm). Mental states such as anxiety can keep a person awake at night, which makes them prone to sleepiness during the day. Depression saps energy and can also cause changes in sleep patterns, such as sleeping much more or much less than usual. Medications such as alcohol, caffeinated drinks, tranquillisers, sleeping pills and antihistamines can disrupt sleeping patterns.
Medical conditions such as hypothyroidism (underactive thyroid gland), oesophageal reflux, nocturnal asthma, chronic pain, heart disease, diabetes, and depression can all disrupt sleep. Changes to time zones, such as jet lag, can also affect the internal biological clock, which regulates sleep.
Sleep disorders such as sleep apnea, restless legs syndrome, sleep walking, narcolepsy, idiopathic hypersomnia, and insomnia may all cause sleep disruption or fragmented sleep. Sleep apnea, for example, is a breathing disorder characterized by brief pauses in breathing during the night, which creates fragmented sleep that typically causes daytime drowsiness. Restless legs syndrome causes a strong sensation of needing to move one's extremities, particularly the legs, and is a known risk for disrupting total sleep time and sleep quality.
Ageing may also be a factor, as older adults may experience changes in biological cycles leading to less time in the deep sleep part of the cycle and waking up more often in the middle of the night.
Lifestyle habits such as smoking cigarettes, drinking alcohol, and consuming caffeinated drinks near bedtime can negatively impact sleep quality. Not following a relaxation routine to prevent night-time anxiety, a lack of regular exercise, an unhealthy diet, and disturbances in one's environment (e.g. watching television in the bedroom) can also contribute to poor sleep.
On the other hand, maintaining a regular sleeping routine, taking brief 'power' naps during the day, exercising regularly, eating a well-balanced diet, and reducing disturbances in one's environment can all help to improve sleep quality.

Mental and physical health factors
Excessive daytime sleepiness (EDS) can be a symptom of underlying mental or physical health issues. It is important to discuss your sleep patterns with your doctor to identify the cause and improve your sleep habits. Seeking advice from a sleep disorder clinic can also help address excessive sleepiness.
Mental Health Factors
Mental health conditions such as anxiety, depression, and stress can contribute to EDS. Anxiety can keep people awake at night, making them prone to sleepiness during the day. Depression saps energy and can cause changes in sleep patterns, such as sleeping more or less than usual. Untreated depression may worsen or prolong these symptoms. Additionally, a noticeable change in sleep routine can be an early sign of depression.
Physical Health Factors
Physical health conditions, including chronic pain, arthritis, fibromyalgia, hypothyroidism, oesophageal reflux, nocturnal asthma, and chronic pain syndromes, can disrupt sleep and lead to EDS. Age-related changes in biological cycles can also result in less deep sleep and more frequent awakenings. Older adults may be more susceptible to EDS due to these biological changes.
Furthermore, certain medications, alcohol consumption, and substance use can contribute to EDS. It is crucial to discuss your medication and potential side effects with your doctor, as they can guide you on timing and dosage adjustments.

When to seek professional help
While sleeping more than usual may be harmless, it could also indicate an underlying medical condition. If you are concerned about the amount of sleep you are getting, it is a good idea to talk to your healthcare provider. They may recommend a sleep study to rule out any sleep disorders or other medical conditions.
You should seek professional help if you are experiencing any of the following:
- You regularly need more than eight or nine hours of sleep per night to feel rested. This could be a sign of a sleep disorder or another medical problem.
- You are experiencing disrupted sleep or poor sleep quality due to conditions such as sleep apnea, restless leg syndrome, or bruxism.
- You are experiencing hypersomnia, which is characterised by excessive daytime sleepiness and the inability to stay awake during the day, even after getting a full night's sleep. Hypersomnia can be caused by various factors, including inadequate sleep, shift work, environmental factors, and mental states such as anxiety.
- You are consistently struggling to fall asleep, stay asleep, or wake up feeling unrested. This may indicate underlying issues such as insomnia, anxiety, depression, or a sleep-related breathing disorder.
- You rely on over-the-counter sleep aids or substances like alcohol to fall asleep.
- You suspect you may have a sleep disorder, such as insomnia, sleep apnea, or restless leg syndrome.
- Your sleep issues are affecting your mood, energy levels, focus, or daily functioning.
It is important to note that sleep needs can vary from person to person, and there are also natural changes in sleep needs throughout life. However, if you are concerned about your sleep habits or they are impacting your daily life, it is always best to consult with a healthcare professional for personalised advice and guidance.
