Battling The Urge To Sleep: Reclaiming Your Day

Feeling sleepy all day can be a symptom of hypersomnia, a condition characterised by extreme sleepiness during the day despite getting adequate or more than adequate sleep at night. People with hypersomnia may nap during the day, fall asleep during the day, and still sleep for long hours at night. Other symptoms include difficulty waking up in the morning, daytime naps that don't improve alertness, anxiety, irritability, slow thinking, and memory problems. Hypersomnia can be caused by a variety of factors, including sleep disorders, medications, medical or psychiatric illnesses, lifestyle factors, and environmental factors. If you are experiencing hypersomnia, it is important to consult a healthcare professional for diagnosis and treatment.

Hypersomnia and its causes

Hypersomnia is a condition characterised by excessive daytime sleepiness and oversleeping. People with hypersomnia often struggle to stay awake during the day, which can significantly impact their daily life and overall well-being. Hypersomnia can affect a person's ability to function at work and socially, and it can also increase the chance of accidents.

The causes of hypersomnia vary and are often unknown. However, some potential causes include:

• Underlying medical conditions, such as epilepsy, hypothyroidism, encephalitis, multiple sclerosis, Parkinson's disease, obesity, obstructive sleep apnea, delayed sleep phase syndrome, and mood disorders (including depression, bipolar disorder, and seasonal depression).
• Medications and substance use, including sedatives, anti-hypertensive drugs, anti-epileptic drugs, anti-parkinsonian agents, skeletal muscle relaxants, antipsychotics, opiates, cannabis, alcohol, and stimulant drugs.
• Lifestyle factors, such as insufficient sleep, poor sleep habits, shift work, and environmental factors (e.g., a snoring partner, a baby that wakes up frequently, noisy neighbours, uncomfortable mattress, etc.).
• Genetic factors: A family history is present in up to 39% of people with idiopathic hypersomnia, suggesting a possible genetic link. Researchers are also exploring the role of certain genes in the circadian rhythm that may be different in people with idiopathic hypersomnia.

It is important to note that hypersomnia is a chronic illness without a cure, and it is more common in females than males, usually diagnosed in adolescence or young adulthood. Treatment options include medications, non-drug therapies, and lifestyle changes to improve sleep quality.

Lifestyle factors that cause tiredness

There are several lifestyle factors that can cause tiredness. These include:

• Diet: An unbalanced diet or skipping meals can leave you feeling tired. Diet-related causes of fatigue include deficiencies in zinc, vitamin B12, or vitamin D, blood sugar fluctuations, excessive alcohol, and too much caffeine.
• Dehydration: Dehydration occurs when you lose more fluids than you take in, and it can quickly deplete your hydration levels. Water makes up 50% to 60% of your body weight, so it's important to stay hydrated to maintain energy levels.
• Poor sleep habits: Sleeping in a noisy or uncomfortable environment, skipping a bedtime routine, exercising too close to bedtime, or napping late in the day can all disrupt your rest. Not getting enough sleep for your age (7 to 9 hours for adults) can also leave you feeling tired.
• Inactive lifestyle: A sedentary lifestyle can lead to restless, poor-quality sleep. Regular physical activity has been shown to improve sleep quality and mental health.
• Overexertion: Overexerting yourself through excessive exercise or other activities can deplete your body's energy reserves, leading to fatigue, poor sleep, and low motivation.
• Stress: Psychological stress can disrupt your sleep, and poor sleep can, in turn, increase stress and fatigue. Managing stress through therapy or other techniques can help improve sleep quality.

Making lifestyle changes, such as improving sleep habits, increasing physical activity, and managing stress, can help reduce tiredness and improve overall energy levels.

Medical conditions that cause tiredness

Feeling sleepy all day can be a symptom of hypersomnia, a condition where you feel extreme daytime sleepiness despite getting more than enough sleep at night. It can be caused by a variety of factors, including insufficient or inadequate sleep, sleep disorders, medications, and medical or psychiatric illnesses.

• Sleep Disorders — These include sleep apnoea, insomnia, restless legs syndrome, sleep walking, narcolepsy, idiopathic hypersomnia, and Kleine-Levin syndrome.
• Chronic Conditions — Certain chronic conditions can cause severe and long-lasting fatigue. These include chronic fatigue syndrome, anemia, vitamin deficiencies (such as vitamin D or vitamin B12), dehydration, and hypothyroidism.
• Infections — Various infections can lead to fatigue, including viral or bacterial infections such as the flu, mononucleosis, and COVID-19.
• Mental Health Conditions — Fatigue is a common symptom of mental health disorders such as depression, anxiety, bipolar disorder, and seasonal affective disorder.
• Autoimmune Disorders — Autoimmune diseases like multiple sclerosis, rheumatoid arthritis, and Sjögren's syndrome often have fatigue as a symptom.
• Heart and Lung Problems — Cardiovascular and lung conditions, such as postural orthostatic tachycardia syndrome (POTS), chronic obstructive pulmonary disease (COPD), and congestive heart failure, can cause fatigue.
• Other Conditions — Conditions like fibromyalgia, cancer, diabetes, and obesity can also lead to tiredness and fatigue.

Sleep disorders that cause tiredness

Sleep disorders can be a major cause of tiredness and fatigue. There are over 80 different types of sleep disorders, and they can affect your quality of life, work life, and social life. Here are some sleep disorders that can cause tiredness:

Insomnia

Insomnia is a common sleep disorder that involves difficulty falling or staying asleep. It can be caused by various factors, such as menopause, medical conditions, psychological stress, poor sleeping environments, and excessive mental stimulation. Insomnia can lead to chronic fatigue and tiredness throughout the day.

Sleep Apnea

Obstructive sleep apnea is a disorder characterised by snoring and moments during sleep when breathing stops or becomes shallow, disrupting sleep. This results in low blood oxygen levels and can affect the heart and brain. Sleep apnea often leads to chronic fatigue and can increase the risk of stroke or heart attack if left untreated.

Restless Legs Syndrome

Restless legs syndrome is a sleep disorder that causes an urge to move the legs when trying to fall asleep. It can make it challenging to fall asleep and stay asleep, leading to tiredness during the day.

Narcolepsy

Narcolepsy is a sleep disorder that affects the ability to regulate sleep and wakefulness. People with narcolepsy experience extreme sleepiness during the day and may fall asleep suddenly. They may also have vivid dreams, sleep paralysis, and muscle weakness triggered by emotions.

Shift Work Sleep Disorder

This disorder is common among those who work night shifts or irregular hours. It can disrupt the sleep-wake cycle, leading to difficulty falling asleep, staying asleep, and increased sleepiness at unwanted times.

Hypersomnia

Hypersomnia is characterised by extreme daytime sleepiness despite getting adequate or more than adequate nighttime sleep. People with hypersomnia may sleep longer than average but still feel sleepy during the day. They may experience "sleep drunkenness," where they have difficulty waking up and appear confused or combative. Hypersomnia can affect work, social life, and overall quality of life.

If you suspect you may have a sleep disorder, it is important to consult a healthcare professional for proper diagnosis and treatment. They can help identify the specific disorder and provide personalised advice and interventions to improve your sleep and reduce tiredness.

Mental health issues that cause tiredness

Feeling sleepy all day can be a symptom of hypersomnia, a condition where you feel extreme daytime sleepiness despite getting more than enough nighttime sleep. Hypersomnia can be caused by a variety of factors, including sleep disorders, medications, and medical or psychiatric illnesses. Mental health issues that can cause hypersomnia or tiredness include:

• Depression: Depression can sap your energy and make it difficult to fall asleep or stay asleep, leading to hypersomnia.
• Anxiety: Anxiety can keep you awake at night, making you prone to sleepiness during the day.
• Bereavement and grief: Grief can disrupt your sleep and cause mental and physical exhaustion.
• Emotional exhaustion or burnout: Feeling overwhelmed and exhausted due to prolonged stress or demanding responsibilities can lead to hypersomnia.
• Life events: Major life changes or stressful events, such as moving home, getting a divorce, or experiencing financial problems, can impact your sleep and contribute to hypersomnia.
• Neuroticism: Individuals with neurotic personality traits tend to worry and experience negative emotions more frequently, which can disrupt sleep and lead to tiredness.

It is important to note that while these mental health issues can contribute to tiredness, there may also be other factors at play, such as lifestyle choices, medical conditions, or sleep disorders. If you are experiencing persistent tiredness, it is always a good idea to consult with a healthcare professional for a proper diagnosis and treatment plan.
