Experts say not to overdo it: How much water should we drink daily?

Water plays a vital role in the human body as it constitutes approximately two-thirds of our body weight, facilitates the transportation of nutrients and waste products, helps to regulate body temperature, and contributes to most chemical reactions in our body. However, the question of how much water we should drink daily remains.

For years, the commonly circulated recommendation has been to consume eight glasses of water per day to maintain normal bodily functions, and thirst is often considered an indicator of dehydration. However, this may not be entirely accurate. Experts suggest that our body signals us when we need to drink water, and we do not need more fluid than what our body requires to quench our thirst.

According to Irwin Rosenburg, a scientist at Tufts University's Neuroscience and Aging Laboratory in Massachusetts, USA, hydration control is one of the most advanced mechanisms developed in evolution since our ancestors transitioned from sea to land. Our body has developed a range of sophisticated techniques to ensure we maintain adequate hydration levels

If you are healthy, your body has a complex system to detect and regulate hydration levels, including the release of a hormone that signals the kidneys to conserve water by concentrating urine. Although water is often considered the best source of hydration, other beverages like tea and coffee can also help. Despite the mild diuretic effect of caffeine, studies suggest that tea and coffee can aid in the hydration process.

Moreover, while water is essential for bodily functions, there is limited evidence to support claims that drinking more water can lead to weight loss or other significant health benefits. Ultimately, it is recommended that you drink fluids according to your thirst and hydration needs.
