Why does sitting in a steam room cause one’s heart rate to increase?

235 views

I was sitting in a steam room and noticed my smart watch indicate a sharp rise in my heart rate to coincide with time spent in the steam room. What causes this rise in heart rate, is it the heat and dilation of the vascular system?

Imagine your body is like a car engine. When you sit in a steam room, it’s like your engine gets a little hotter, just like when a car’s engine gets warm when you drive it. Your heart is like a pump that helps your blood flow all around your body, bringing oxygen and nutrients to your muscles and organs.
When you’re in a steam room, your body gets warmer, and your heart needs to work a bit harder to make sure all your body parts get enough blood and oxygen. So, your heart rate goes up to keep up with this extra work. It’s a bit like when a car engine revs up to go faster when you need more power.
So, sitting in a steam room makes your body warmer, and your heart beats faster to take care of your body, just like how a car engine works harder when it gets warm.
