Human beings need to drink water. Drinking water helps maintain the water reserves that make up two-thirds of our body weight, and eliminates waste through the filtration activity of the kidneys.
We lose about 2.5 litres of water each day, and even more with physical activity. It is advisable to drink 1.5 to 3 litres of water per day to maintain our reserves. This requirement can be met by the amount of water in the food we eat, like fruits and vegetables, as well as the liquids we drink, such as water, juice, coffee and tea. Inadequate fluid intake leads to dehydration. The symptoms of dehydration include dizziness, chills, headaches and muscle fatigue.
As for drinking with meals, while you might have heard this is to be avoided, this is not supported by the scientific literature. The only issue is that you might experience discomfort caused by the volume in your stomach. The important thing is to drink moderately. So if you like to drink while eating, go right ahead, as long as your consumption is moderate. Furthermore, if you have problems with constipation, it is advisable to drink water during meals to facilitate the transit of food.
Drink between meals, during meals, and above all, when you are thirsty! This is all the more important during heat waves or physical activity.
