The majority of victims that are usually easily affected by heatstroke are the kids and the elderly, as their adaptability to differing temperatures are usually less responsive compared to those in their prime. Those who are severely fat and obese are at also greater risk than those who are slim and fit because the body has a great difficulty dissipating the body heat through the thick layers of lipids and fat.
First aid should be given in haste and should consist of differing methods that should immediately bring the core temperature to at least 39 degrees Celsius. One quick method of doing so is by rubbing the body with a cloth dipped in cold (not ice) water. Alcohol also works fine, as the liquid dissipates into the air fast enough, taking heat away as well; just make sure that you are doing so in a well-ventilated environment.
Should you give a cold bath, do so. But don’t do with an ice bath, as the immediate drop in temperature might lead to cardiac arrest. Once temperature has at least reached the 39 degree mark, slowly lead the body to cool down a bit more slowly now. Don’t shock the body with an immediate temperature change, never forget this.
A lesser form of heatstroke, or rather a milder version of it, is heat exhaustion. This less severe condition occurs when the afflicted person feels tired, fatigued, and a bit nauseous and dizzy because of profound and long exposure to heat.
This is because of over sweating, which leads to the excessive loss of body salts and electrolytes, though the body is at a normal or below normal temperature thanks to it. Giving first aid means having small sips of salt water to replenish the lost salts and a massage to areas affected by cramps, which usually follows after heat exhaustion.
