Dehydration means that your body is losing more fluid than you are taking in. if it isn’t treated it can get worse and become a serious problem. In the heat it is extremely important to drink plenty of water, even if you don’t feel thirsty. The first sign of dehydration is thirst. But there are many other symptoms which include:

  • Headaches

How to treat someone that has just fainted:

  • Kneel down beside them and raise their legs on your shoulders, look at their face to see if there is any signs of recovery
  • Get people to stand back and make sure the individual has enough fresh air
  • Once they feel better help them sit up slowly.
