Don't sweat: ways to stay cool in the heat

One simple bowl of ice can keep you cool three different ways.

Scientists first started studying how weather contributes to human comfort in the 1960s. That's around the time when the invention of air conditioning finally let us control the temperatures of homes and buildings.

If your ancestors survived without air conditioning, so can you. Remember when refrigerators were iceboxes that contained actual blocks of ice?

One simple bowl of ice can keep you cool three different ways.

First, you can make a DIY air conditioner by positioning a shallow pan or bowl full of ice in front of a fan. The breeze will pick up cold water from the ice's surface as it melts, creating a cooling mist.

Your body regulates its temperature via a small peanut-shaped section of the brain known as the hypothalamus. This region works almost like a thermostat in a home, turning the temperature up or down based on various factors such as how cold or hot the skin is.

If you're still feeling hot, you can trick your brain into turning down its thermostat. Wrap some ice, and put it on the back of your head/neck, wrists, and the insides of your elbows and knees. Essentially, areas where you can feel your pulse because your blood vessels are close to the surface of your skin.

Chilling those pulse points with cold water or ice sends a signal to the brain that says, "I'm cold."

Many people think that the head is the part of the body that receives and thus expels most of the heat from the body, but it turns out that our feet are actually the best when it comes to getting rid of excess heat in the body.

They have a large surface area and specialized blood vessels, thereby allowing more blood to flow. Adding some water and placing your feet in a ice cold foot bath can cool your body and allow you to sit back and relax.

Lastly, you may want to add a few drops of peppermint essential oil or for an added cooling effect. The menthol found in mint triggers nerves and sends electrical signal to the brain which creates the sensation of feeling cooler.

These remedies can help to cool you down if you're feeling the heat. But If your body temperature seems to be high for an undetermined reason or you're not cooling down after trying some of these remedies you may want to check in with your doctor.
