Cold showers or ice baths can release norepinephrine and epinephrine, potentially relieving aspects of depression related to low levels of these neurotransmitters.

“exposing oneself to cold water of various kinds can in fact increase our levels of dopamine as well as the neuromodulator norepinephrine.”

“And I do believe that these documented effects in humans explain much of the enhancement of attention and of feelings of wellbeing and mood that people typically experience after doing deliberate cold exposure.”

“deliberate cold exposure can increase in norepinephrine and dopamine, which is that they observed no significant increases in the stress hormone cortisol and that is both surprising, interesting, and important because what it means is that the quality of stress that deliberate cold exposure is creating in the body is likely to be one of what we call use stress.”

“today you'll learn how deliberate cold exposure can be used to cause increases in the release of several, if not, all of these in ways that can improve your levels of attention and your mood.”

“these elevations in norepinephrine and dopamine are very long lasting in ways that people report feeling vast improvements in mood and vast improvements in levels of cognitive attention and energy. So by my read of the literature, these seem to be healthy increases in our baseline levels of these chemicals in ways that can really support us”

“Because I talk all about the science. I'm familiar with all the science, and the norepinephrine or noradrenaline, it's affecting brain and mood. You know way more about that than I do. I know how I feel, and I know it's a neurotransmitter, and it is released, at least, in rats, they've shown. Or was it mice? I think it might've been rats. But multiple studies showing that it's released from the cold in the brain. - And now, in humans as well.”

“There have been beautiful studies showing that if people get into a very cold body of water, four degrees Celsius for 20 seconds. As I mentioned earlier, that will cause the a 200 to 300% increase in norepinephrine. Norepinephrine is also called noradrenaline. And norepinephrine and other so-called catacholamines like dopamine increased dramatically in this very brief cold water exposure. And those increases in norepinephrine and dopamine are known to have long-lasting effects that generally lead to improvements in mood, focus, and alertness.”

“If you get into a very cold shower or you take an ice bath, you will release norepinephrine and epinephrine in your brain and body. There's no question about that. If some aspects of depression are related to low levels of norepinephrine, will taking cold showers relieve your depression? Perhaps. It might even relieve certain aspects of that depression.”

“Getting into cold showers, taking ice baths, exposing oneself to cold water of various kinds can in fact increase our levels of dopamine as well as the neurom modulator neuroepinephrine.”

“we can boost levels of norepinephrine in the brain so for that focus and acuity”

“people that have been down regulated significantly maybe that looks like chronic depression get into the ice bath and they're like holy [ __ ] i feel really good well it's because your norepinephrine just got increased 500 percent after only three minutes of cold exposure maybe like 40 degrees and it stays”

“on the cold front the norepinephrine your it's that's been shown so animal studies have shown or norepinephrine released in the locus coleus treason or the brain after cold exposure and a variety of cold water exposure cryotherapy if you're doing a cold water 50 degree you know if it's like 50 degrees Fahrenheit you gotta stay in a little longer than like a couple of minutes in a really cold cryotherapy chamber but in humans plasma norepinephrine has been looked at which does seem to sort of correlate with the release”

“Cold shock (cryo or cold water) can induce norepinephrine for focus/attention.”

“And I know that's norepinephrine is being released. It's been shown with cryo and cold-water immersion.”

“Please send me that because I've been theorizing that that would be the case based on the fact that cold, if you're, I think it's around 60, anything below 62 or 63 degrees Fahrenheit, 17 degrees Celsius, whatever that is. It increases norepinephrine and that's...”

“So, if you just think about the cold itself increases norepinephrine, which is used to treat ADHD, it's used to treat depression, they're giving norepinephrine reuptake inhibitors to treat that, which have all sorts of side effects. And then the breathing increases the epinephrine, which then causes all the anti-inflammatory response.”

“how it's important for norepinephrine how norepinephrine helps you focus it helps you um feel good and also helps with anxiety as well and it causes the production of new mitochondria both in your adapost tisue and cold uh causes the production of your mitochondria in your muscle tissue”

“increasing norepinephrine through cold exposure while not completely risk-free shows promise as a way of addressing these aspects of mental health”

“you can you could do your HIT protocol, which is my fave, or you can do your your 2 minutes at 50° Fahrenheit and get that norepinephrine boost.”
