Perimenopause Fatigue: Why You're So Exhausted

Perimenopause fatigue comes from disrupted sleep (night sweats, insomnia), fluctuating hormones, and often overlapping thyroid issues. Prioritizing sleep, screening for thyroid problems, exercising, and managing stress help restore energy.

Fighting perimenopause exhaustion

Fatigue has multiple drivers that are all worth addressing.

  • Prioritize sleep and address night sweats if they wake you.
  • Screen for thyroid issues, which are common in perimenopause.
  • Exercise even when tired—it builds energy over time.
  • Manage stress and set boundaries to prevent burnout.
