Is it true that ... a cold shower is the best way to cool down on a hot night?
Want to lower your temperature and drift off to sleep quicker? An ice-cold shower might seem the best solution, but the truth is more complicated

TL;DR
- Ice-cold showers can stimulate the release of adrenaline and cortisol, hormones that promote alertness, making it harder to sleep.
- Very cold water causes blood vessels near the skin to constrict, reducing circulation and trapping heat inside the body.
- A tepid shower, ideally in the mid to high 20s Celsius, is more effective for cooling down before bed by allowing heat to dissipate through the skin.
