Introduction
Under normal circumstances, drinking salt water after eating lychees may have a certain auxiliary effect in alleviating heatiness symptoms, but the effectiveness is limited and cannot replace proper dietary control. In daily life, the key to preventing heatiness caused by eating lychees still lies in controlling the amount consumed, while also pairing them with some cooling vegetables and fruits to maintain a balanced and diverse diet, thereby better maintaining physical comfort.

Generally, drinking salt water after eating lychees may have a certain auxiliary effect in alleviating symptoms of excessive internal heat, although the effectiveness is limited and it cannot replace proper dietary control. Detailed analysis is as follows:

Lychees are a warm-natured fruit with high sugar and calorie content. Excessive consumption can lead to accumulation of internal heat in the body, causing symptoms such as dry mouth, sore throat, and oral ulcers. When salt water enters the body, it can help replenish fluids lost due to internal heat to some extent, relieve dryness in the mouth and throat, and its mild saltiness can stimulate saliva secretion, helping to ease the discomfort caused by excessive heat.

However, the effect of salt water is relatively mild and should only be considered an auxiliary method. If obvious symptoms of excessive internal heat have already been triggered by overconsumption of lychees, simply drinking salt water is unlikely to provide significant improvement. The concentration of salt water should be appropriate—excessively concentrated salt water may increase the burden on the kidneys and be harmful to the body.

In daily life, the key to preventing excessive internal heat caused by eating lychees is to control the amount consumed, while balancing the diet with cooling vegetables and fruits, maintaining dietary diversity and balance, which better supports overall physical well-being.
