After beginning of autumn, the temperature gradually turned cold, but it was still high during the day, so we should choose fresh and peaceful foods that nourish yin and clear away heat, moisten dryness and quench thirst. You can choose sesame, red dates, honey, tremella, longan and other plain products. On weekdays, you can soak a little jujube honey water or longan honey water in a thermos cup, and choose a good thermos cup to make yourself have the habit of drinking water at any time. Personally, I use a thermos cup with buckle, which has good insulation effect and high value. Unconsciously, I will increase the frequency of drinking water.
