Thermostat wars: how hot is this getting?

Hot flashes and night sweats (the official term is vasomotor symptoms) are some of the most common and most disruptive parts of perimenopause. As estrogen falls, the part of your brain that regulates temperature gets twitchy, so a tiny change reads as a full heat emergency. It is genuinely physiological, not a personality quirk, even if it has turned you into someone who guards a window. Find out how hot this is getting.

How Phaes helps after the quiz

Hot flashes and night sweats are not just uncomfortable, they raise the cost of every workout and quietly steal the sleep you recover on. Phaes does not just track your cycle and symptoms, it reads a short daily check-in, including how hot and how rested you are, and turns it into a running and strength plan that eases when the heat is winning and pushes when you are genuinely ready.

Questions women ask about this

Why am I suddenly so hot all the time in perimenopause?

Falling and fluctuating estrogen disrupts the part of your brain that regulates temperature, narrowing the comfortable zone so small changes trigger a flush of heat. That is what hot flashes and night sweats are. They often begin before periods become irregular, can be set off by stress, alcohol, caffeine, or warmth, and can range from occasional to many times a day.

Can I still exercise with hot flashes?

Yes, and you should, exercise has big benefits in midlife, but a few tweaks help. Train in cooler conditions, hydrate well, wear breathable layers, and ease the intensity on days the heat is intense rather than pushing through it. Exercise can temporarily trigger a flash because it raises your core temperature, so timing harder efforts for cooler windows makes a real difference.
