Not many of us are fortunate to live in places where the climate is conducive to perfect running conditions. Even the most suitable climates have their off days. If you are training for a long distance race such as a marathon you cannot be too choosy about the weather you want to do your training in. You have to discipline yourself to the point that the type of weather whether, it is cold, hot or wet should not be the deciding factor of why you should train or not. Someone said there is no such thing as bad weather just bad clothing.
If you live in a climate where it normally has high levels of humidity then avoid running during the day. The best time is early in the morning or the early evening.
One of the greatest dangers when running in hot weather is the risk of dehydration. This means your body does not have enough fluids to function properly. Dehydration can lead to a number of health complications that can include heat stroke.
It is important that you take plenty of fluids when you are running in hot and humid weather. A natural sign of dehydration is feeling thirsty. At this point the body has already passed the point of losing insufficient water. You should not wait to drink until you are thirsty you should drink to prevent it. The more serious signs of dehydration are a light-headedness, dizziness, stomach cramps and diarrhoea.
Another serious risk of a lack of fluids in the body is sun stroke. The symptoms of sunstroke include a lot of body perspiration which speeds up the rate of the body losing fluids. A hot fever is also another common symptom. If the body is not replenished with sufficient fluids then sunstroke can lead to collapse or even a coma.
To ensure you are properly prepared for running in hot and humid conditions take plenty of fluids. Depending on how you do it, some runners will drink fluids before the race or during the race. The key thing is to listen to your body. If you feel dizzy then you should stop immediately and ask for medical assistance. The best fluids to drink are fresh filtered water and non carbonated sports drinks. Some runners find that drinking water is not effective enough to keep them rehydrated and their energy levels up therefore, they combine drinking water with a sports drink such as Gatorade.
