On hot, stuffy summer days, people tend to sweat a lot. That is why they must get enough water, rather than drinking only when they feel thirsty. This is especially important for middle-aged and elderly people. Lack of water may result in speeding up the ageing process, or even death, as it may lead to reduced blood flow and/or damage to the heart. In addition, the body will sweat less and produce less urine when it lacks water. As a result, harmful substances will accumulate in the body, which may lead to poisoning. People should drink water
several times a day-a little bit at a time-rather than drinking a lot of water in one go. Therefore, people should develop the habit of drinking water at four key times of the day-early in the morning, after getting up, around 10 am, between 3 pm and 4 pm, and before going to bed. People should also pay special attention to drinking water, to replenish the body, after sweating excessively, doing exercises or taking a
shower. In addition, eating vegetables and fruits can serve several purposes, such as replenishing water and providing the necessary minerals and nutrients.
