Your body dehydrates if your fluid intake is less than what your body puts out. You lose fluids by breathing, sweating, exercising, urinating, vomiting etc so when your body doesn’t have enough fluids to carry out its normal functions, you get dehydrated.

The common causes of dehydration are: vigorous exercise or exercising in hot weather, diarrhoea, vomiting, fever or excessive sweating. It is very important to replace any fluids that you’ve lost before you get dehydrated.

The symptoms of mild dehydration are:
* thirst
* dry sticky mouth
* sleepiness or tiredness
* decreased urine output
* dry skin
* headache
* constipation
* dizziness

When the colour of the urine is darker, it can be an indication that you’re getting dehydrated.
What to do? Increase the fluid intake! Pay attention when the hot weather comes that you need to drink enough water throughout the day. When you exercise, always drink water to replenish the fluids you lose by sweating.

It’s worth mentioning that sometimes water retention can be an indication that you’re not drinking enough fluids. When you drink less water than what you put out, your body is trying to balance it by retaining some water to prevent dehydration. When you experience mild dehydration what you need to do is start drinking more water slowly to replenish the lost fluids.

This is not the only cause of water retention though. It could be just as simple as having too much salt, spices or sugar in your diet.
