Water is the driving force in our bodies, as about 65% of the body is water, thirst can leave you in a state of confusion or lethargy, but it can also affect your brain, says US university research – quoted in a report published in “Science Daily.”

Researchers at Penn State University found that not getting enough water could also be linked to cognitive performance. Among older adults, water intake was linked to their scores on several tests designed to measure cognitive function, and they found that among women lower levels of hydration were associated with lower scores in a task designed to measure motor speed, sustained attention, and working memory did not find the same result for men.

“The study gives us clues about how water and related drinking habits are related to cognition in older adults,” says Hilary Bethancourt, a postdoctoral researcher in bio-behavioral health and first author of the study in the Science Daily. “This is important because older adults already face an increased risk of cognitive decline with age and are often less likely than younger adults to meet daily water intake recommendations.”

“As we age, our water retention decreases due to reduced muscle mass, our kidneys become less effective at retaining water, and the hormonal signals that cause thirst and stimulate water intake to contract,” Bethancourt said.

“As older adults may not necessarily feel thirsty when their bodies reach a state of dehydration and may use diuretics that may increase salt excretion, it is important for older adults and their doctors to address the symptoms of both a deficiency and an excess of water.

How much water should a person drink per day?

According to the Mayo Clinic, a healthy adult living in a temperate climate needs an adequate daily fluid intake of about 15.5 cups (3.7 liters) of fluid per day for men. About 11.5 cups (2.7 liters) of fluid per day for women.

How much water should you drink per day if you fall into this category? Dr Sifter says water intake should be individualized, and you should consult your doctor if you are not sure what amount is right for you.

After all, water intoxication is also a bad thing. Water intoxication, also known as water intoxication, is a disorder of brain function caused by drinking too much water. In severe cases, water poisoning can cause seizures, brain damage, coma and even death. Drinking a lot of water can increase the pressure in the skull. It can cause several symptoms.
