Staying up all night will cause symptoms of “fire”, i.e. upset and sleeplessness, dry mouth and throat, constipation, etc. The kidney essence can not be filled up to consolidate the warmth and function well, so that the yin fluid is reduced. Staying up all night prevents the kidney essence from filling up, and the function of fixing (consolidating) and warming cannot run well, so the yin fluid decreases and the evidence of yin deficiency appears. The specific manifestations of kidney yin deficiency are lumbar and knee soreness (lumbar and knee soreness and weakness), dizziness, tinnitus, heartburn and insomnia, dry throat and mouth, hot flashes (a burst of heat), night sweating (abnormal sweating after going to sleep, and waking up sweating stops), etc., and the treatment of nourishing yin and tonifying the kidneys, the formula of the six flavors of the ground pill, Zuo Gui Pill, and so on. If you are not feeling well, you should consult a doctor in time and choose medication under the doctor’s guidance, not self-medication. You also need to adjust your own habits, avoid staying up late, go to bed early and get up early, develop good habits, eat a light diet, and exercise properly.
