But did anybody check their shower water temperatures before they croaked?
“Solution: pre-warm your shower.”
...I’m always reminded of the shower scene from Psycho. She gets into the shower, then turns it on. Insanity.
They must be dropping like flies in Sweden and all the other places where they run out of the sauna and jump into the snow.
Explains why French have fewer heart attacks.
!!!!!
This is one of the reasons snow shoveling can be dangerous.
Blood pressure is the product of cardiac output (the amount of blood your heart pumps per minute) times the peripheral resistance (the resistance to blood flow - usually controlled by the constriction or relaxation of the small blood vessels - e.g. arterioles).
Blood pressure = Cardiac Output x Vascular Resistance
Usually, when you exert yourself there is an increase in heart rate and contractility of the heart - leading to increased cardiac output which will increase your blood pressure in accordance with the above relationship.
At the same time, as you exercise, you produce heat and also specific metabolites. This leads to dilation of the resistance blood vessels, and thus decreases vascular resistance. This blunts the rise in blood pressure.
In the winter your peripheral resistance vessels (e.g. in skin, your extremities, any body surface exposed to the cold) will contract, decreasing blood flow to those tissues. This helps to preserve body heat by decreasing the amount of warm blood being exposed to tissues that are exposed to the cold.
The problem is that if you start shoveling in the cold outside in the winter you will have an increase in cardiac output while at the same time having an increase in vascular resistance. This leads to a significant increase in blood pressure, and thus stress on larger blood vessels and on the heart. Eventually, as you shovel, you will generate metabolites and body heat that will blunt this vasoconstriction - but until you do you are at increased risk.
I post this because the principles are similar to those operative in the shower scenario.
I think that’s common in some Scandinavian countries.
If anyone’s wondering, it’s because of cold water quickly shrinking the smaller blood vessels in the body which increases cardiovascular pressure temporarily. Solution: pre-warm your shower.
It’d Darwinian there. The one’s that died didn’t live to reproduce!
“thanks for giving the concise version, rarestia!”
Agree, you have to read a thousand words in that fluff of an article to get to that simple piece of info. And how many people take cold showers??
I guess it’s all on purpose to make you scroll through a hundred ads to get to the bottom line.
Many were worried it was about peeing in the shower...................

Peeing not a problem as it goes on down the exit tube. It’s
the poop that causes problems as it has to be stomped on to
get it into and thru the drain.
My cardiologist recommends people wait at least thirty minutes after they eat before taking a shower. I should have asked why, but I just do it.
The American Heart Association cites research showing that “plunging into cold water during hot weather can cause heart attacks even in young, fit and healthy individuals”.
So...No more jumping in a pool on a hot day. This getting ridiculous
Sure a lot of PR out there lately trying to convince you everyone, no matter the age, was ALWAYS dropping dead (en masse) of heart attacks, blood clots, “natural causes”, etc.
Yeah, but how often do those threads show up?
I have to click on a UK newsrag to find out what this bad habit is?

Finland - sauna capitol of the world
If anyone’s wondering...
Thanks!
Terrible writing of burying the lede. Get with it for God’s sake.
This is just story one of getting the public out of the habit of daily showering.
Y’know...
For the planet...
