The heat exhaustion is a heart – related illness. It is happening after you have been exposed to high temperatures and it is often accompanied by dehydration.  There are 2 types of heat exhaustion – water depletion (signs and symptoms of this condition include loss of consciousness, headache, weakness and excessive thirst) and salt depletion (dizziness, muscle cramps, vomiting and nausea). The heat exhaustion is not serious as a heat stroke but this is not something which should be taken lightly. If you do not have proper intervention, then the heat exhaustion can progress to heat stroke and this can damage the brain and other vital organs and even it can cause death. The most common symptoms of heat exhaustion are: rapid heartbeat; profuse sweating; pale skin; nausea, vomiting or diarrhea; muscle or abdominal cramps; headache; fatigue; fainting; dizziness; dark – colored urine (a sign of dehydration) and confusion.  This condition is strongly related to the heat index, which is a measurement of how hot you feel when the effects of relative humidity and air temperature are combined. The relative humidity of 60% or more hampers sweat evaporation and this hinders your body’s ability to cool itself. Infants and children up to age 4 and adults who are over age 65 are having the biggest chances of getting heat exhaustion because they adjust to heat more slowly than other people. When you go outside, then you should use a sunscreen with an SPF of 30 or more. Talk with your doctor if you have heat exhaustion before you start using some of the below mentioned home remedies.
