It's normal to feel tired sometimes. But if you're tired all the time and do not know why, it could be a sign of a problem.

Causes of tiredness and fatigue

Common causes of tiredness and fatigue include:

  • not getting enough sleep or finding it hard to get to sleep (insomnia)

  • hormonal changes (such as during puberty, pregnancy or the menopause)
  • some illnesses, like glandular fever and COVID-19
