Hot flashes and night sweats

Stop hot flashes and night sweats from breaking up your night. These guides rank remedies, bedding and treatments by what the trials measured.

• Breathable bedding for night sweats: which fibres help?

  For night sweats, pick fibres that absorb moisture: cotton, linen, lyocell or wool. Cotton holds 7-8% of its dry weight in moisture, polyester 0.2-0.4%. The only cooling-sheet study in people with night sweats, 64 adults in 2025, was uncontrolled, with fewer symptoms reported. Use the label checklist; see a GP if sheets are regularly soaked.

• Why are hot flashes worse at night, and how to sleep through

  Hot flashes feel worse at night because they cut into sleep, and women who get them have almost no comfort range for core temperature: 0.0 °C in a 1999 lab study, against 0.4 °C without flashes (American Journal of Obstetrics and Gynecology). If flashes wake you most nights, hormone therapy, fezolinetant, gabapentin and CBT beat placebo in trials.
