## Quick answers
Q: Why do I sleep so hot even with the AC on?
A: Air conditioning cools the air, but if your mattress, bedding or partner is holding heat against your body, your skin can still overheat. The fix is usually at the sleep surface: breathable layers and, for persistent hot sleepers, active bed cooling.

Q: Why do I sleep hot but my partner is cold?
A: People differ in body size, muscle mass, hormones and how much they move at night. Separate blankets help; a dual-zone cooling and heating system lets each side choose its own temperature.

Q: Is it normal to sleep hot?
A: Running a little warm at night is common, and most causes are about your environment and habits. If you also sweat heavily, it started suddenly, or you have other symptoms, check with a doctor.

Q: Why do I sleep hot after drinking?
A: Alcohol widens blood vessels near the skin so you feel warm and flushed, and as it wears off it disrupts sleep, which is when many people wake up hot.

Q: Why do I sleep hot before my period?
A: After ovulation, progesterone rises and nudges your body temperature up slightly until your period starts, according to Cleveland Clinic. Many people notice warmer nights in that window.

Q: What temperature should my bedroom be to stop sleeping hot?
A: Cleveland Clinic suggests roughly 60 to 67°F for most adults. Hot sleepers often do best at the lower end, with light bedding.

Q: Do cooling sheets fix sleeping hot?
A: They can help a little. Passive cooling fabrics feel cool at first but warm up as they absorb your heat. Active cooling, such as a water-based topper, keeps removing heat all night.

Q: When is sleeping hot a medical problem?
A: When it's new and unexplained, when you're soaking the sheets, or when it comes with fever, weight loss, a racing heart or other symptoms. Then it's worth seeing a doctor.
