Your skin is the largest organ in your body, and is responsible for helping to control the temperature of your body through sweating.
Since your body creates a lot of heat through metabolic processes, it’s important that it’s able to regulate temperatures properly.
When you’re dehydrated, your skin isn’t able to produce as much sweat and you can become overheated. This can lead to symptoms as mild as red flushing or as serious as heat stroke.
So when you’re hot, make sure to drink lots of water to ensure your body can cool itself properly.
