Cold water shock

Cold water shock

What is hydrocution?

Hydrocution (more commonly known as cold water shock) happens when we suddenly transition from a very hot place to a very cold one.

The temperature difference between the warm body and cold water causes a thermal shock. The heart starts beating more slowly, leading to dizziness, vomiting, and even fainting.


Having a full stomach doesn't help, but you don't need to wait long before swimming, as long as you don't submerge suddenly. You need to gradually enter the cold water so that your body has time to adjust to the water temperature.

And remember, always ask your doctor!
