If you use diet to regulate your body, both the north and the south need to get rid of summer heat, but the nuances are different. In the relatively dry northern region, Chinese medicine believes that "summer heat" will hurt "body fluid", causing fatigue, dry mouth, dry skin and other symptoms. Therefore, northerners should cope with the "summer heat", add more water, and the diet should be based on nourishing yin and promoting fluid production. You can eat more fruits that nourish yin and promote fluid production, such as watermelon, pear and raisin. In addition, northern families can cook porridge with chrysanthemum, mung bean, lily and reed root, which can also play the role of clearing heat and nourishing yin.
