I've been swimming in Lake Superior. Didn't last long.

is one way to shock your heart into normal rhythm if you have arrhythmia.

Doesn't work all the time, but if you suffered from WPW like me, try it before getting on the more serious drugs or ( like me ) having the surgery to correct it.

Wolff-Parkinson-White (WPW) syndrome is a heart condition present at birth. That means it's a congenital heart defect. People with WPW syndrome have an extra pathway for signals to travel between the heart's upper and lower chambers. This causes a fast heartbeat. Changes in the heartbeat can make it harder for the heart to work as it should.

WPW syndrome is fairly rare. Another name for it is preexcitation syndrome.

The episodes of fast heartbeats seen in Wolff-Parkinson-White syndrome usually aren't life-threatening. But serious heart problems can occur. Rarely, the syndrome may lead to sudden cardiac death in children and young adults.

Treatment of WPW syndrome may include special actions, medicines, a shock to the heart or a procedure to stop the irregular heartbeats.

someday it will likely kill me. I was born "dead" so... every day I cheat death is a good day.
I was lucky that I survived until there were drugs to treat it, then I survived the trips to the ER to use the shock paddles... and then the new drugs... and finally the SECOND type of corrective surgery ( microwave instead of laser from inside the heart )... and now waiting on the scar tissue formed by the microwave to sluff off and finally kill me... could be anytime now. who knows, maybe I will live long enough for a decent artificial heart.

Even thinking about doing so is anxiety inducing.

me famished.

I've been emotionally wiped out lately due to grief. I'm surpised it hasn't left me physically cold. Probably need another ECG.

I'll try cold water therapy again. I've been running hot recently. Maybe it'll help me "reset" somehow.

And there are always those who do the "polar plunge".

but i like it on the face and forearms esp. wrists. It cools you off. Also luckily i live in the whites (mountains) so when its really hot the cold brooks warm up enough for me. Brushing your skin activates the same system/

Closest I’ve come is ‘cool’ showers if there’s no AC and it’s hotter than a popcorn fart outside.

I guess my health comes first.

It wakes me up better than caffeine.

Early morning summers here in west central Florida are about 77º-80º. After my walk I jump/saunter into the shower and just use the cold tap on the shower. I'd say the water temp is about ? 74-75º ?
Not really that cold but it's totally refreshing and cools me off right quick.. The first blast is the worst but I get use to it quickly...
YMMV

I just know I like my showers warm.

I take a coolish shower in the evening. Cold with a little bit of warm water mixed in. I don't think my heart could handle a cold shower.

We lived on a Navy base and one of the requirements for using the pool was you had to take a shower before entering the swimming pool. There was an outdoor shower by the entrance and when you stepped onto the wood platform the shower would begin. Of course, it was cold water and we'd stand under for about 30 - 45 seconds and then jump into the pool. The pool's water was much warmer than the shower's water so we'd immediately feel a rise in temperature of about 20 or more degrees. I'll admit, that warm feeling made me feel good.

Can't handle it for very long, but it's supposed to help with spinal pain. Not really sure if it helps, but tiny relief is still relief I suppose

Hot flashes and night sweats have had me taking cold showers for a few years. The summer heat and hot showers make me nauseous.

I feel like a kid again
