Feeling sleepy all day and fatigued can be caused by a variety of factors, including lifestyle choices, medical conditions, sleep disorders, and mental health issues. Inadequate sleep, sleep disorders, medication, and medical or psychiatric illnesses are all possible causes of excessive sleepiness. Physiological fatigue can be caused by a lack of sleep, dietary choices, or too much or too little exercise. Secondary fatigue can be caused by underlying health conditions, whereas chronic fatigue can last longer than six months and is not alleviated by rest or sleep.

What You'll Learn
Sleep disorders
- Insomnia: This is the most common sleep disorder, characterised by difficulty falling or staying asleep.
- Sleep apnea: A breathing disorder where breathing stops for 10 seconds or more during sleep, often causing loud snoring.
- Restless leg syndrome (RLS): This disorder causes tingling or prickly sensations in the legs, along with a powerful urge to move them.
- Hypersomnia: People with hypersomnia are unable to stay awake during the day and may fall asleep suddenly.
- Circadian rhythm disorders: These are problems with the sleep-wake cycle, making it difficult to sleep and wake at the right times.
- Parasomnia: This disorder involves acting in unusual ways while falling asleep, sleeping, or waking from sleep, such as walking, talking, or eating.
If you suspect you may have a sleep disorder, it is important to consult a healthcare professional for a proper diagnosis and treatment plan. They may recommend lifestyle changes, such as improving sleep habits, or they may suggest cognitive behavioural therapy or relaxation techniques to reduce anxiety about sleep. In some cases, medication or medical devices may be prescribed to help manage the sleep disorder.

Lifestyle factors
Sleep Habits
Poor sleep habits, such as not getting enough sleep or having irregular sleep patterns, can lead to daytime sleepiness and fatigue. Aim for 7-9 hours of sleep per night and maintain a consistent sleep schedule, even on weekends. Create a bedtime routine and optimize your bedroom environment by keeping it dark, quiet, and at a comfortable temperature. Limit screen time and avoid caffeine and large meals before bed.
Diet and Nutrition
A well-balanced diet that includes fruits, vegetables, and lean protein is essential for maintaining energy levels. Eat frequent small meals and choose snacks with low sugar content. Avoid highly processed foods and excessive caffeine or alcohol consumption, especially close to bedtime.
Physical Activity
Regular physical activity and exercise can help reduce fatigue and improve sleep quality. However, a lack of exercise can contribute to fatigue and deconditioning, making physical tasks more tiring. It is important to gradually introduce exercise and consult with a healthcare professional if needed.
Mental Health
Mental health issues, such as depression, anxiety, and emotional exhaustion, are often associated with fatigue. If you are experiencing symptoms of mental health disorders, it is important to seek professional help. Talk therapy and medication can be effective treatments for managing mental health and reducing fatigue.
Substance Use
The use of certain substances can disrupt sleep and contribute to fatigue. This includes the consumption of caffeinated and alcoholic beverages, especially close to bedtime. Nicotine use can also impact sleep quality.

Mental health issues
Anxiety is another mental health issue that can lead to fatigue. Feeling worried, stressed, scared, or tense can be a normal response to certain situations, but if these feelings occur frequently or without a clear cause, you may be experiencing anxiety.
Additionally, psychological factors such as depression and grief can be common causes of fatigue. Prolonged feelings of sadness, dejection, and hopelessness may indicate depression, while losing a loved one can cause a range of emotions, including shock, guilt, depression, despair, and loneliness.
Chronic stress can also lead to fatigue and, in some cases, stress-related exhaustion disorder (ED). Chronic stress can cause structural and functional changes in the brain and contribute to chronic inflammation, which can result in symptoms like fatigue.
If you are experiencing mental health issues and fatigue, it is important to seek help from a healthcare professional, such as a therapist or counsellor, who can provide support and guidance.

Environmental factors
Your sleep schedule and fatigue can be heavily influenced by your surroundings and the environment you're in. Here are some environmental factors that could be contributing to your daytime sleepiness and fatigue:
Light Exposure: Exposure to natural light during the day and limiting blue light from screens close to bedtime are crucial for regulating your sleep-wake cycle. Not getting enough sunlight during the day or overexposure to artificial light at night can disrupt your body's natural sleep patterns, leading to fatigue and daytime sleepiness.
Noise Pollution: Excessive noise, whether during the day or at night, can interrupt your sleep quality. If you're exposed to loud or persistent noises in your environment, it can cause sleep disturbances and leave you feeling tired during the day.
Temperature and Comfort: The temperature and comfort of your sleeping environment are essential. A bedroom that is too hot or too cold can disrupt your sleep. Additionally, an uncomfortable mattress, pillows, or bedding can impact your sleep quality, contributing to daytime fatigue.
Work and Home Environment: The places where you spend most of your time, such as your workplace or home, can significantly impact your sleep and energy levels. Poor air quality, uncomfortable temperatures, or ergonomic issues at your workplace can contribute to fatigue. Similarly, clutter, inadequate lighting, or a lack of comfortable spaces at home can affect your sleep and overall energy levels.
Social Factors: Social factors, such as your work schedule, social activities, and family responsibilities, can influence your sleep. If your daily schedule is packed with commitments and activities, it may leave you with insufficient time for quality sleep, resulting in daytime fatigue.
Addressing these environmental factors and creating a comfortable, peaceful, and consistent sleep environment can improve your sleep quality and reduce daytime fatigue. Making adjustments to your surroundings and daily routines can positively affect your overall energy levels and well-being.
