SAUNA + WOMEN’S HORMONES
Sauna isn’t just sweating. For women in peri and menopause, heat directly influences cortisol, estrogen, insulin and mood.
The rise in core temperature creates a brief cortisol bump, followed by a deeper drop, leaving you calmer and more resilient. Increased circulation supports the thyroid, adrenals and ovaries, helping metabolism and energy. Dopamine and norepinephrine rise too, improving mood and focus.
Heat activates heat-shock proteins, which make your cells more sensitive to estrogen and insulin. This supports blood sugar, metabolism and more stable hormonal signalling as estrogen naturally declines.
With consistent use, sauna improves insulin sensitivity, supports thyroid and adrenal balance, reduces fatigue and mood swings, eases hot flushes and improves sleep. As you cool, your parasympathetic system switches on, creating deep relaxation and hormonal reset.
Important: It’s best to avoid wearing HRT patches in the sauna. Heat can increase transdermal absorption and cause a higher hormone release than intended.
The sauna isn’t just a sweat. It’s a science-backed tool for hormonal balance and midlife longevity.
