Heat cramps, are muscle spasms that result from loss of large amount of salt and water through exercise. The cramps are associated with cramping in the abdomen, arms and calves. This can be caused by inadequate consumption of fluids or electrolytes. However, during the hot weather, people who work hard and sweat a lot sometimes get painful cramps in their legs, arms or stomach. This usually occurs because the body lacks salt.
Heat exhaustion is a condition whose symptoms may include heavy sweating and a rapid pulse, as a result of your body overheating. It’s one of three heat-related syndromes, with heat cramps being the mildest and heatstroke being the most severe. A person who works and sweats a lot in hot weather may become very pale and weak and perhaps feel faint. Though the skin cool, moist and the temperature are normal, but the pulse is rapid and weak.
Heat stroke is not common but it is very dangerous. It occurs especially in older people and alcoholics during hot weather. It’s a condition caused by your body overheating also, usually as a result of prolonged exposure to or physical exertion in high temperatures. Heatstroke is the most serious form of heat injury which can occur if your body temperature rises to 40 C or above. The condition is most common in the summer months. However, heatstroke requires emergency treatment and if left untreated, it can quickly damage the brain, heart, kidneys and muscles. The damage worsens the longer treatment is delayed, increasing your risk of serious complications or even death.
