Drinking water with lemon slices can help the body absorb its rich vitamin C content, maintaining the normal physiological function of body tissues.

It can also enhance the body's resistance, not only improving immunity but also effectively preventing and treating diseases like kidney stones due to the citrates in lemon slices. Additionally, drinking water with lemon slices can effectively relieve symptoms such as coughing and excessive phlegm caused by a cold.

Lemons are rich in vitamin C and also contain vitamins A, B1, and B2, which not only have whitening effects but also help lighten melanin in the skin.

The ideal water temperature for soaking lemon slices is around 60-70°C.

If the water used for soaking lemons is too cold, the fragrance is not easily extracted. If boiled water is used, more bitter substances such as hesperidin are dissolved. Lemon is acidic, and vitamin C is heat-resistant in acidic conditions, so it is not easily lost. Therefore, a water temperature of around 60-70°C is generally suitable for soaking lemons.
