While bathing with cold water, it is always advised not to directly pour it on the head as sudden cold water exposure can have numerous side effects, such as cardiovascular stress, brain hypothermia, and more. Tap to know more!

Cardiovascular Stress

When we suddenly pour cold water on the head, the blood vessels constrict, putting stress on the heart and increasing blood pressure.

Nerve Pain

The sudden cold water exposure can also cause nerve pain, as it irritates the facial or cranial nerve. It can sometimes lead to temporary facial paralysis.

Brain Freeze

When the head is suddenly exposed to cold water, the blood vessels constrict and dilate rapidly, causing a sharp pain in the brain and leading to headaches.

Dizziness

Sudden cold water exposure can cause you to feel dizzy, as the water may stimulate the inner ear affecting balance and leading to falls.

Brain Hypothermia

Pouring cold water on the head can cause brain hypothermia as the head loses heat faster than any other body part, leading to dizziness, fatigue, and more.
