When the weather is as hot as it is right now, a cold drink filled with ice seems like the go-to option, right?
Well, you might want to think again, after one person on Facebook posted a warning about drinking ice cold water in the blazing heat.
Adam Schaub, from Houston, Texas, took to Facebook to share his story after a terrifying experience a couple of years ago.
He wrote: "So we've all heard not to drink really cold water in the heat, but a lot of us haven't heard the why or experienced it first hand.
"Cold water is good, so how could it be bad? Well, yesterday I found out. We were out working in 100° weather (not a good idea in itself) when my dad noticed my face was getting pretty red and suggested that I take a break.
"I immediately grabbed a cold bottle of water and drank it. After he did a little more work he suggested that I get in the truck and blast the a.c.
"In the truck, I drank some more cold water and very shortly started feeling strange. I started seeing spots, my stomach got extremely nauseous and my hands and feet started tingling. I felt like I was going to throw up so I opened the truck door and the next thing I know I'm face first in the ground and my dad's rolling me over and wiping off my face.
"He said my eyes had rolled back a bit and I didn't come to for a few minutes. EMT arrived and asked what was going on. Immediately the guy knew what happened.
"Apparently, if you're too hot and chug a bottle of cold water, it can send your body into shock. It thinks that the stomach is going hypothermic and so it takes the warm blood from your hands, feet and head and sends it to the stomach.
"You will lose consciousness. He said cold water is good, but only in sips. Room temperature water is better if you need fast rehydration.
"Just figured I would share in case anyone could benefit from my mishap. Summer's just around the corner. Stay cool. Feel free to share if you think it could help someone. I wish I had learned this a long time ago."
Speaking to The Sun GP Dr Sarah Jarvis explained what she thinks might have happened.
She said: "If you drink something very cold, very quickly, the cold on the roof of your mouth stimulates the nerves around there. That in turn leads to rapid contraction, then expanding of the tiny blood vessels in your sinuses.
"The brain interrupts the messages from these nerves as coming from your forehead, because the same nerve supplies your forehead. You usually get a sudden pain, but it can make you feel lightheaded.
"... Regardless of the cause, I do see people who feel unwell due to drinking cold fluids too quickly, so I certainly don't recommend it."
While Adam originally shared his story back in 2018, it's certainly worth keeping in mind with this week's heatwave!
