Never drink drinks that are too cold. And this for several reasons, not only for the possibility of congestion if we were in the digestive phase. Drinking too cold drinks can suddenly also cause you severe headaches. But because?

The explanation is simpler than one might think and is yet another demonstration of how perfect we are as we are delicate. Our balance is a so sophisticated mechanism to go into "alarm" very easily.

Drinking an ice cold drink, especially if we do it all of a sudden, ours blood vessels they tend to shrink, for entirely mechanical reasons, referring to basic physics principles: the cold "shrinks", the heat "expands". And all the vases do it, even those behind the neck.

However, as soon as the "frost" effect vanishes, the heat of the blood expands everything again and this "pulsation" interferes with the nervous system, particularly affecting the trigeminal nerve, because of even terrible headaches.

Now the question is: why do we undergo this stress knowing that the result can be this? The answer is often not there. Or rather, it's called instinct: when it does a lot hot we naturally drink cold drinks. We can't do much about it.
