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 **** ## Source - [[Huberman Labs]] - [[Good Energy (book)]] - [[Simple Science Fitness]] ## Related - [[Adrenaline]]
