Note

Freeze, then sauna, same hour

Covers off. Covers on. The loop is the night, not a bad pillow.

The thermostat is broken. Covers off. Covers on. Sheets soaked. Pants and bra bands can hurt because everything touches wrong.

A cooling pillow or a fan helps until the wave hits. Then it does not. Estrogen moved to the morning can leave the night heat. A small dose can let it return.

The useful distinction is bed versus room. A fan cools the air. The wave is on the body. People who failed pillows and fans name airflow on the body — BedJet is the device they name, Chilipad the mattress pad.

Track when the wave hits so you are not guessing. One change, then watch a week.

Not a diagnosis. Not medical advice. The quiz names whether heat, sleep, or something else is loudest right now.
