Study: Fan Use When Dehydrated May Trigger Heart Attacks

Sleeping with a fan on might seem refreshing, but a study found it could be risky, especially when you're not drinking enough water.

Scientists put people in a hot room and tested how fans affected them.

They checked things like heart rate and how much they sweat.

They discovered that using a fan can make you sweat more, and if you're already low on water, this could put extra stress on your heart.

The study suggests that while fans can help in moderate heat, they can be harmful in very hot conditions, especially if you are dehydrated.

So, make sure you stay hydrated!
