In our last Q and A episode, we covered a lot of ground on improving sleep quality, especially REM and Deep sleep for those using tracking devices.
Since then, I’ve gotten more questions and had several conversations with some listeners who are using cold showers before bed to improve sleep quality.
In this episode, we’ll explore why this works, what the research says, and how you can use cold exposure to possibly improve subjective quality of life, fall asleep faster, and get better sleep.

- Research Cited in the BHP Short:
- Both too hot and too cold can have negative impacts on sleep quality:
- REM sleep negatively impacted by elevated temperatures (35 C vs 20 C):
- Median quality of life (subjective) was higher after 30 days of cold showers – but anxiety, sleep, and other secondary results were not impacted.
- CAUTION: Cold exposure might increase the risk of sleep-related cardiovascular events in prehypertensives.
