We lose water all the time—mainly through sweat and urine. To stay hydrated and healthy, it’s therefore necessary to keep replacing the water that we lose.
Water makes up about two-thirds of the total body weight and we need it to help our body to carry out all its most fundamental functions. In moderate climates, aim to drink six to eight glasses of water or other healthy liquid each day, but you’ll probably need more than this when the weather is hotter and if you’re more physically active, so make sure that you tune into what your body tells you.
However, try to avoid waiting until you feel parched before taking a drink because your body will already be suffering by this stage. It’s a good idea always to carry a bottle of water with you to sip at and stay well hydrated throughout the day.
