Sleep-related issues:

Insomnia: Difficulty falling asleep or staying asleep can lead to chronic fatigue.

Restless leg syndrome: Uncontrollable urge to move legs, especially at night, can disrupt sleep.


Poor sleep hygiene:

  • Irregular sleep schedule

  • Excessive caffeine or alcohol consumption


Medical conditions:

Anaemia: A lack of red blood cells can lead to fatigue.

Thyroid disorders: Hypothyroidism (underactive thyroid) can cause fatigue.

Chronic fatigue syndrome: A complex disorder characterised by extreme fatigue that doesn't improve with rest.

Fibromyalgia: A condition associated with widespread pain, fatigue, and sleep disturbances.

Diabetes: Poorly managed diabetes can lead to fatigue.

Chronic pain: Conditions like arthritis or migraines can cause persistent tiredness.


Psychological factors:

Anxiety: Constant worry and tension can lead to exhaustion.

Stress: High levels of stress can wear you out over time.


Lifestyle factors:

Poor diet: Nutrient deficiencies can contribute to fatigue.

Lack of exercise: Sedentary lifestyles can lead to a lack of energy.

Excessive alcohol or drug use: These substances can affect sleep and overall well-being.

Overworking: Burnout from excessive work can result in chronic tiredness.


Medications:

Some medications, including antihistamines, antidepressants, and certain blood pressure drugs, may cause fatigue as a side effect.


Infections:

Chronic infections like mononucleosis, Lyme disease, or viral hepatitis can lead to persistent fatigue.


Allergies:

Seasonal or chronic allergies can disrupt sleep and lead to tiredness.


Hormonal changes:

Menopause, pregnancy, and conditions like polycystic ovary syndrome (PCOS) can cause fatigue due to hormonal fluctuations.
