In addition to dehydration, the body also loses electrolytes and minerals. However, drinking water should be scientific , the amount of water should be distributed evenly throughout the day.

Using ice water is also a choice of many people to reduce the feeling of thirst, heat and improve mood. However, if using water that is too cold below 5 degrees Celsius, a large amount can increase the risk of sore throat, toothache, infection from unclean ice, affecting the digestive system.
