Proven benefits of drinking water are observed in patients with constipation, headache, problems with concentration
In the human body, water represents approximately 60% of its composition, and in newborns the percentage is higher. The recommendations are to drink at least 8 glasses of water a day or calculated in liters - at least two liters.
Adequate hydration of the body is important for maximum effect during exercise. Otherwise, there is a faster onset of fatigue, difficulty in performing the exercises, difficulty in controlling the maintenance of body temperature (leading to overheating) and others. Adequate hydration is also involved in reducing oxidative stress, which is not surprising, provided that the muscles consist of 80% water.
Adequate hydration is also related to brain function. A scientific experiment shows that in young women, the loss of only 1.36% of body fluids after physical activity leads to a decrease in concentration and mood, while increasing the incidence of headaches.
A similar experiment in men shows that reducing body fluids by 1.59% leads to a significant reduction in memory (memory ability), while increasing the feeling of fatigue and even anxiety.
Drinking enough water can have a prophylactic and even therapeutic effect on headaches. In some individuals, dehydration may be a trigger for migraine episodes. Several studies have concluded that restoring water balance can reduce headaches. The role of good hydration on the intensity of pain is emphasized, not so much on the frequency of headache episodes.
In case of constipation (constipation) at the beginning (before the appointment of drug therapy), the specialists recommend both a change in the diet (enrichment with fiber) and an increase in fluid intake. Reduced water intake is defined as a risk factor for constipation, both at a younger age (children and adolescents) and in the elderly.
It is believed that the consumption of carbonated water also gives results in constipation, although the reasons are still being clarified.
