1. Hydrate yourself
2. Protect your skin
Try to dress protecting your head with caps, hats or similar. Another basic point that you should add to your life routines is the use of a powerful sunscreen on your face and neck, which will protect your skin from the damage caused by the sun's rays. Eye protection is also important, with sunglasses you will be avoiding direct sun exposure on your face.
3. Avoid sun exposure
The hours of greatest radiation occur between 11:00 a.m. and 3:00 p.m., so it is recommended to carry out outdoor activities before or after that time to avoid heat stroke.
4. Avoid drinking alcoholic beverages
Alcohol dehydrates you, which can cause you to lack the water and fluids necessary for normal body function. On the other hand, alcohol makes you sweat more and the "combination of sweating more in the heat and going to the bathroom more means you lose more fluid than you take in" and you can become dehydrated quickly.
5. Do not do intense physical activities under the sun
The body is not able to maintain a low temperature. Normally we regulate our body temperature through sweating, we expel water that cools us when it evaporates. Extreme heat, humidity, and exercise in the sun may make this measure insufficient. Headache, rapid pulse, dizziness, nausea, weakness then appear.
6. Wear loose, light-colored, long-sleeved clothing
Light colors reflect more of the radiation they receive than dark colors, which absorb more radiation than the former. By absorbing more radiation, they heat up faster, reach a higher temperature, and transfer more heat into the body.
Remember that prevention is better than cure
