If you notice any of these first signs, they could be indicative of dehydration and it’s important to boost your fluid intake immediately by drinking water.
What are the risk factors for dehydration?
You are at risk of getting dehydrated if you don’t drink enough water every day. Australian guidelines recommend men drink 10 cups of fluid a day and women drink eight cups. One cup is around 250ml.
While you can get fluids from a range of drinks, including tea, coffee, juice and soft drinks, water is the healthiest choice – so always opt for water if possible.
You are also at risk of dehydration if you do activities that cause you to get too hot or lose too much fluid, like:
- sweating excessively during a workout – if you lose too much sweat during a workout and don’t replace it with water, you may get dehydrated
- spending too much time in the sun – this can cause your body to overheat, meaning you lose too much fluid and become dehydrated
