What it’s for
- Comfort and preparing for sleep
A shower with comfortably warm water, sometimes used to unwind before bed.
Purpose, evidence and practical considerations.
Studies of pre-bedtime warming suggest possible improvements in sleep onset. They do not establish a special recovery effect after a sauna or cold plunge.
Confidence: weak
Water that is too hot can burn skin or cause dizziness and fainting through vasodilation. Use caution with impaired sensation, mobility limitations or unstable blood pressure.
Warm water raises skin temperature and can support relaxation. Before bed, passive heating may promote later heat loss, but shower-specific evidence is limited and depends on timing and temperature.
