Drinking water can keep you healthy. Drinking water is not only something everyone has to do every day, but also the cheapest and simplest way to keep fit! However, there are many "pits" in the small matter of drinking water. Take the water temperature as an example. Drinking too hot water will "burn" the oral cavity and esophageal mucosa, and too cold will stimulate the gastrointestinal tract. In fact, water temperature has many effects on health. If you don't drink it correctly, the effect of health care and disease prevention will be greatly reduced! Warm water of 35℃ ~ 40℃ is the most comfortable temperature for gastrointestinal tract.
