Dr. Keith Grimes, a general practitioner in Babylon, confirmed to the British "Metro" that there are signs that the body needs water and is about to dry out, including headaches, feeling tired and feeling hot, dry mouth, and nausea.
"In hot weather, our bodies lose more water through sweating and breathing, which increases the risk of dehydration. Fortunately, humans have adapted brilliantly to this challenge over thousands of years, and we have a number of mechanisms to maintain our fluid fluid balance, and organs help Sensing in our brains to detect changes in the state of hydration, leading to thirst and reduced urination.
He explained, "Symptoms of mild dehydration can include headache, fatigue, nausea, or dry mouth or lips. There is no evidence to support the myth that thirst is a late sign, so listen to your body and fill it with water as needed."
Some people do not have clear signs of dehydration, and if this is the case for you, you can get small sips of water and regular, throughout the day.
Dr. Grimes notes that as people get older, their thirst for drought will diminish, for example; So as you age, you should make sure that you keep yourself full of water throughout the day instead of waiting for thirst.
Parents will need to ensure that children have permanent fluids. Because they may not know the signs of dehydration, or be unable to express their thirst.
Some medical problems such as diabetes or heart disease may require more specific recommendations about drinking fluids, so if you have an underlying condition, talk to a medical professional.
Grimes noted: "Alcohol and caffeine drinks can lead to increased fluid loss (diuresis), but most experts don't think this contributes significantly to the risk of dehydration. If you feel nauseous, avoid soft drinks or dairy products, try instead Small and frequent sips of water. "
He continued: "In the end, the healthy human body adapts well to the challenge of warmer days. Drinking reasonable fluids, along with keeping cold and protecting yourself from sunlight, and avoiding exertion at the hottest time of the day, is the simplest way to stay in good shape. And when it comes to a certain amount of water you must drink it, and do not exert yourself too much about the exact number of the amount that should be drunk. "
The British National Health Service recommends that you drink about 1.2 liters (six to eight cups) on a regular day, and more when it's hot.
