Cold exposure, especially at around 50 degrees or longer durations, significantly increases dopamine, norepinephrine, and epinephrine levels, which are collectively called catecholamines. These increases are two to three times above baseline and can last for several hours, unlike most drugs that spike dopamine briefly. The amplitude and duration of dopamine release through cold exposure are unparalleled, leading to enhanced mood and energy levels throughout the day. This physiological response is superior to any drug or conventional form of exercise in terms of catecholamine elevation and duration, making it a beneficial practice, especially for athletes who utilize cold exposure before their workouts.
