Did you know that tap water is good for your health?
Water is an essential element for life and an essential nutrient in our daily diet. The human body is comprised primarily of water, which plays vital functions, which is why it is essential for proper hydration when ingested adequately.
Water needs vary depending on age, gender, physiological status, physical activity and the environmental temperature, so that the water needs of an adult person are a minimum of 1.5 litres per day.
We highlight below the minerals that tap water may contain and which are essential for the human body:
Calcium is necessary for the formation and maintenance of bone tissue. It is, therefore, an essential element for the proper growth and mineralization of bones and teeth. The calcium provided by tap water is very important to meet the daily needs of children, adults, people with osteoporosis and those with lactose intolerance, because it can be a source of calcium to be taken into account.
Thanks to the contribution of calcium that tap water can contain, a daily consumption of 1.5 litres of water promotes the following:
The formation and maintenance of bone tissue. The appropriate growth and mineralization of bones and teeth. The regulation of blood pressure. The reduction of kidney stones. The reduction in body weight. Decreased risk of colorectal cancer.
Water rich in calcium and magnesium has a stronger taste, but it can have a positive effect on blood pressure and help prevent cardiovascular disease.
Magnesium is essential for bone mineralisation and for many functions, such as the transmission of neuromuscular activity and central nervous system and cardiac function. The World Health Organization estimates that an adult needs to consume between 220 and 260 mg of magnesium daily. Tap water can contribute significantly to the recommended daily allowance of magnesium.
Tap water can contain significant amounts of magnesium, so that a daily consumption of 1.5 litres of water favours the following aspects:
- Bone mineralisation.
- Transmission of neuromuscular activity, of the central nervous system and cardiac function.
Water rich in calcium and magnesium has a stronger taste, but it can have a positive effect on blood pressure and helps prevent cardiovascular disease.
The presence of sulfates and bicarbonates in drinking water is potentially beneficial to health. Bicarbonates have digestive properties and can help prevent kidney stones. Sulfate-rich water can also have a mild laxative effect.
- Is 1.5 litres of water a day enough?
It is difficult to establish the exact amount of water a person should drink daily, as needs often vary depending on different factors, such as physical activity, climate, age and sex, among others.
The recommended intake of water for healthy adults is 1 ml per kilocalorie per day, or between 2 and 3 litres of water per day.
Of this, between 75 and 80% should be obtained from drinks (mainly water, milk, juices, teas, soups, etc.), while 20 or 25% should come from solid foods, such as fruit and vegetables.
- Do you know the recommendation for starting and ending the day?
While we sleep, we lose water. It is therefore advisable to drink at least one glass of water before going to bed and another when getting up.
- Why do we have to be well hydrated?
When you sweat, your body loses water and minerals. 99% of our sweat is just water, but also minerals such as sodium, potassium, magnesium and iron are found in our sweat.
Good hydration allows the recuperating of water values that the human body needs, and prevents certain disorders, such as vomiting, headaches, tiredness, dry skin, etc.., symptoms associated with dehydration.
- Do you know why we shouldn’t have to wait until we’re thirsty to drink water?
Water loss suffered by the body every day (more than 2 litres) should be replaced as quickly as possible to prevent the dehydration process from beginning.
It is therefore very important not to wait to until we get thirsty before drinking water, as this is a characteristic symptom of dehydration.
- Do you have to drink more water when you exercise?
Drinking half a litre of water two hours before exercising is essential for adequate hydration and to allow time for the body to eliminate the excess of ingested water.
During exercise, hydration is recommended at regular intervals to replace all the water lost through sweating. After exercise, it is vitally important to drink water in order to recover adequately.
- Should children take extra precautions?
In the case of children, it is important to take scheduled stops when working out or between games to drink enough water and thus aid hydration.
- Do the elderly need to be more hydrated?
For the elderly, it is essential to control water consumption, given that with age there are changes in renal function and a significant decrease in the sensation of thirst.
- Did you know that you should drink more water if you have the flu or diarrhea?
The common cold, flu and diarrhea often lead to dehydration, so in these states it is necessary to drink water regularly.
Tap water contains minerals and other nutrients that usually provide it with a particular taste and smell. For this reason, water rich in calcium, potassium and magnesium has a more intense flavour.
To improve the taste and smell of water, it is advisable to place it an open glass jar below a tap, let it stand for half an hour to allow the chlorine to evaporate and then put it in the fridge. The actual cooling of the water mitigates the taste and smell of chlorine.
If you also add a drop of lemon, the flavour will be enhanced.
