Can you drink honey water after eating lychee?
Generally, it is safe to drink honey water after eating lychees, although excessive consumption is not recommended. The detailed explanation is as follows:

Lychees are high in sugar and may cause dry mouth or throat discomfort after consumption. Honey water, which is neutral in nature and sweet in taste, can moisten the lungs and promote saliva production. When consumed together, they help alleviate the internal heat sensation caused by lychees. The fructose and glucose in honey provide energy and complement the sugars in lychees, helping maintain stable blood glucose levels. Additionally, the mild, soothing texture of honey water balances the excessive sweetness of lychees, aids digestion, and reduces gastrointestinal discomfort that may result from overeating lychees—making this combination particularly suitable during summer.
When consuming lychees, limit portion size to no more than 10 at a time. When pairing with honey water, pay attention to its concentration; it's best prepared with warm water to avoid destroying honey’s nutrients with boiling water. Avoid eating lychees on an empty stomach—instead, drink a small amount of honey water beforehand to line the stomach. Since lychees spoil easily, choose fresh, plump ones with unbroken skins, and consume them promptly after peeling. If symptoms such as dizziness or palpitations occur after eating lychees, drinking warm honey water may help relieve discomfort. Avoid strenuous exercise and opt for light meals with fresh vegetables and fruits to support recovery and restore physical comfort.
