Water is a colorless liquid composed of hydrogen and oxygen (H20). It is vital for life, although it supplies no calories. The human body comprises around 60% water.
But don’t put your water bottle or glass down just yet. While we may not need eight glasses, there are plenty of reasons to drink water. In fact, drinking water (either plain or in the form of other fluids or foods) is essential to your health.
Drinking adequate amounts of water, or staying hydrated, is the first rule of health and nutrition. Our bodies can supposedly last weeks without food, yet just a few days without water.
Here some health benefits of drinking water:
May improve memory and mood
Hydration impacts the brain, as well as the body, and research has shown that even mild dehydration may have a negative impact on moods and may heighten anxiety.
May aid weight maintenance
The brain can’t actually tell the difference between hunger and thirst, so often we mistake thirst as a ‘sugar craving’. The next time you feel the need for something sweet, try a glass of water first.
having water before a meal may fill you up more and therefore promote weight loss through suppressing your appetite.
May improve exercise performance
There has been a lot of research into the effects of hydration or dehydration in athletes, and the results all pretty much conclude that dehydration not only affects sports performance but also physiological function too.
May prevent constipation
Water helps to keep things moving in the digestive system, so staying hydrated may help prevent constipation in children, adults and the elderly.
May support the health of the urinary system
Poor hydration may increase the risk of developing, or the recurrence of kidney stones, in some individuals, drinking adequate amounts of water may reduce the risk of bladder infections and urinary tract infections.
