“Here’s a cool trick to hack your brain to cool down,” Dr. Karan Raj, an NHS surgeon, his social media Video where he explained his cool down tip.

“Your body regulates temperature using this peanut-shaped section of the brain known as the hypothalamus.

“This region of the brain basically acts like a thermostat,” he explained.

“Depending on various factors such as skin temperature, it can increase or decrease the performance of the brain.

“There are certain parts of the skin that can affect the hypothalamus more than others, and these areas are called pulse points.”

“These pulse points are areas where the blood vessels are so close to the skin that you can feel them,” he said.

dr Karan Raj detailed how you can use these pulse points to lower your body temperature.

“If you want to lower your body temperature, cool one of these pulse points with cold water.

“That then triggers your brain to turn the thermostat down.”

He shared that the pulse points that are easiest to reach are the radial artery on the inside of your wrist, the carotid artery in your neck, and the temporal artery around your temple.

Viewers who tested the hack themselves used the comments section to share their experiences.

“I’ve always done that. I run my wrist under cold water when I’m hot and it always cools me down,” one person said.

“I always run cold water over my wrist when I’m hot. A waitress told me about the trick when I was in elementary school in the 1980s,” added another.

“I knew about the wrist but not the head and neck, thanks!! I’m an epileptic and heat is a trigger so that will help a lot,” said a third grateful viewer.

Others said that while they knew the hack worked, they still didn’t understand why it worked.

“So does it feel better if I splash cold water on my wrist when it’s hot?” one person asked.
