High levels of stress lead to a poor night’s sleep. Stress activates the hypothalamic-pituitary-adrenal (HPA) axis, a system of tissues and organs that helps your body respond to stress by increasing energy and decreasing tiredness.

Signs of stress

Stress can sometimes lead to unexpected symptoms, such as:

  • Tiredness
  • Headaches
  • Stiff or painful muscles and joints
  • Digestive changes like indigestion, diarrhea, or constipation
  • Weight changes
  • Sexual problems
  • Memory problems
  • Trouble concentrating
  • Increased use of drugs or alcohol
