Dr. Andrew Huberman loves deliberate cold exposure as a tool for increasing baseline levels of [[Dopamine]], spiking your [[Adrenaline]] and [[Noradrenaline]], and increasing discipline. Forcing this upon yourself also is a way to train your top-down control, increasing your ability to maintain discipline and do other hard things.
Googling this and reading around will find you **mixed recommendations** on whether or not Cold exposure is beneficial... but many sources point toward health benefits.
# Benefits
- Activates [[Brown Fat]]
- May help with sleep
- May increase [[Insulin]] sensitivity (which is good)
- May help the [[Immune System]] and regulate [[Inflammation]]
- Increases baseline levels of [[Dopamine]], per Huberman
# Recommendations
- Huberman recommends **11 minutes per week** for maximum benefit
- At the end of your shower, turn the water cold for ~2 minutes (or work your way up to 2 minutes)
- I saw this referred to as the "James Bond Shower" for some reason
- For those who are more extreme: Ice baths, dips in frigid lakes or pools can work
