This is such a story that if the temperature difference is too large, then from the rapid cooling of the pharynx and blood vessels around it with ice, a reflex will work, and the heart will stop. Therefore, in the heat, you need to drink some water at room temperature. Moreover, cold water is less well absorbed. Like water at room temperature, dehydration can be corrected faster.
It’s not like that. The reflex really works, and even the heart slightly slows down the frequency of its contractions, but these are all small things compared to the harm that overheating will cause you.
That is, I have never heard that someone had a blow from swallowing ice.
When these grandmothers walk down the street with ice cream, do they run the risk of dying from ice cream? I do not think…
In short, things are even worse here than you might imagine. People constantly overheat and constantly die from it somewhere. Therefore, no one ever hesitates to shove such a victim into an ice bath, give him liquid ice to drink, and even cover them with ice bubbles.
The sooner such a person cools down, the less he will damage his head and everything else with a high temperature.
Aren't you afraid of ice cream?
Heat capacity
Athletes have this concept of body heat. When applied to a living organism, this means that you can only survive a certain amount of heat put into your body.
If you are going to cross the desert on foot, then very soon your heat capacity will run out, and the next portion of heat will finish you off.
What do you think, is it possible to increase this heat capacity in any way? Right! You need to cool yourself down in advance. Did everyone get the point?
To start cooling the body, you do not have to wait for that overheating when your brain and heart fail. You need to cool down in advance. That is, even before going out in hellish weather, you need to give up hot drinks and soups, eat cool salad, drink ice water, apply (I seriously!) to the head and favorite parts of the body an ice pack, cool down well and then, with short dashes along the vampire's route, go where you need to It was.
Do not hesitate, brothers, to freeze yourself with ice from the outside or from the inside. This increases your heat capacity and you can handle one more heat wave than other people.
Well, that is, when the others are already overheated and faint, then you will still have enough cold space inside to start another portion of heat there. Is it clear now?
And yes, the icy water can cause headaches and throat pains. The head aches because it is a cold headache. Many had it in childhood from that very quickly eaten ice cream.
And the throat hurts not from infection or from a cold, but from cooling. In the same way as ears chilled in the cold hurt. Nothing bad happens from this. Will hurt and stop.
Liquid ice
Have you tried liquid ice? This piece is produced on an industrial scale by the fish processing industry. It is finely crushed ice in half with sea water. It instantly cools fresh fish to minus 2 degrees and does not spoil its skin.
About the same thing, but with sweet syrup instead of sea water, it is used to quickly cool your insides in the heat. So if you come across such a muck, I highly recommend it.
