8 Possible Reasons You Feel Hot All the Time
Dehydration
When your body temperature is not within optimum parameters, your body has to work overtime to produce sweat and regulate your temperature. Sweat takes the heat to the skin surface where it evaporates, and your body cools down.
If you don’t drink enough water and you become dehydrated, you’re not providing your body with enough water to lower your increased body temperature.
How to solve it: The answer is easy: drink between 6 and 8 glasses of water per day (or other fluids). You’ll be surprised by just how quickly your hot flashes will disappear.
