Our body attempts to regulate it’s own tempriture with an aim to stay approximately in the 37⁰C mark in order to remain healthy. The way in which our body does this is to sweat and we can reduce up to 80% of our heat by doing so, the problem occurs when we don’t drink enough liquid and become dehydrated during hot weather. If our body does becomes dehydrated then it will reduce the amount it sweats to conserve liquid and as a result start to overheat which can cause the following dehydration symptoms.
heat rash, cramps, dizziness, fainting, heat exhaustion, heat stroke and a potential worsening of any existing medical conditions.
Out of all the above symptoms Heat Stroke is considered one of the worse and is generally caused with prolonged exposure to heat or the sun. This symptom can come on very quickly and can become a medical emergency which would require immediate treatment in more severe cases.
In hot climates dehydration is very common but can become life threatening if left untreated. Some people are in a higher risk bracket than others, please see below the groups which are more susceptible to dehydration than others.
People that are working or exercising in extreme heat or direct sunlight.
People who are already suffering with chronic illnesses.
Infants and children:
Elderly people: Whose bodies are less able to conserve water and they are less likely to realise they are thirsty.
When living in or visiting a hot climate, heat related illnesses can be prevented with a few simple measures. Try to drink plenty of cool liquid to reduce the onset of thirst rather than getting thirsty and then drinking. If your food intake has reduced then try to increase the amount of fluids you drink. If possible include as many fruits and vegetables to your diet as they have a high water content. Dress accordingly to the weather by wearing light coloured, loose fitting cool garments.
If you are going to be busy then try and plan it for the coolest parts of the day to reduce the chance of overheating.
In cases of mild dehydration you can reduce the symptoms by drinking plenty of fluids or products that restore fluids, salts and electrolytes all in one which are ideal and available at most shops.
if you are severely dehydrated, professional medical treatment should be sought immediately from your doctor or local clinic
