We all know it's important to keep your body hydrated, but why?
We asked nutritionist Nicola Shubrook to tell us the top five benefits of drinking enough water.
What is water?
Water is a colorless liquid composed of hydrogen and oxygen (H20).
It is necessary for life, although it does not contain calories.
Drinking enough water, or keeping your body hydrated, is the first rule of health and nutrition.
Our bodies can last a whole week without food, but you can only last a day without water.
It makes sense when we know that our body is made up of about 60% water and that dehydration can have physical and mental consequences.
Benefits of water
The exact composition of your glass of water depends on its source.
Mineral water and spring water, which usually come from reservoirs and underground springs, can provide additional nutrients in the form of minerals such as calcium and magnesium.
What are the top 5 health benefits of drinking water?
1. It improves memory
Research has shown that even mild dehydration can affect memory and mood in everyone from children to the elderly.
Dehydration affects the brain, as well as the body, and research has shown that even dehydration can negatively affect mood and increase anxiety.
Dehydration can also increase the risk of headaches or migraines in some people.
2. It can help maintain weight
The brain doesn't tell the difference between hunger and thirst, so we often confuse thirst with "sugar cravings."
The next time you crave something sweet, try a glass of water first.
Keeping the body hydrated can also help maintain weight.
Research has shown that drinking water before a meal can make you feel fuller and thus promote weight loss by suppressing your appetite.
This is what emerges from a 2015 study where light lines were replaced with water.
The results showed that it can lead to more weight loss and insulin resistance.
3. It can improve an athlete's performance
A lot of research has been done on the effects of dehydration on athletes, and the results have concluded that dehydration not only affects the athlete's performance, but also psychologically.
4. May prevent constipation
Water helps to "do things" in the digestive system, so staying hydrated can help prevent constipation in children, adults, and the elderly.
It would seem that water is very beneficial.
5. It can help the health of the urinary system
Dehydration can increase the risk of developing or recurring kidney stones in some people.
Studies have also shown that drinking enough water can reduce the risk of bladder and urinary tract infections, including bladder infections that are commonly caused by bladder infections in women.
How much water is recommended?
The NHS (UK Public Health Service) recommends an adult drink an average of 6-8 glasses of water every day.
This includes low-fat milk, low-sugar or sugar-free drinks, tea and coffee.
However, this may vary depending on your age, gender and activity level.
For example, you may need more water if you are exercising or if it is very hot.
