Why do I often sweat when I sleep at night?

The hot summer has passed, and we no longer have to endure the scorching heat. We can just cover ourselves with a thin blanket when we sleep at night. However, some people say that they are always very hot when they sleep, and sometimes they wake up from the heat. It is even more unbearable in the summer, and in the winter, they are also very hot and their pajamas are soaked. So, why do we often sweat when sleeping at night? Let me introduce it to you now.

Sweating is called "night sweats". Night sweats is a disease name in traditional Chinese medicine, which is characterized by "abnormal sweating after falling asleep and cessation of sweating after waking up". The pathogenesis of "night sweats" in young and middle-aged people is different from that of "night sweats" caused by low blood calcium in children. The transition from winter to spring is a high-incidence period for "night sweats" among young and middle-aged people. The reason is mostly due to the patient's "yin deficiency". In simple terms, after a long winter, the "essence" stored in the human body is insufficient. When the physical fitness declines, symptoms of night sweats will appear, such as hot flashes, red cheeks, irritability, night sweats, insomnia, fatigue and so on. Young and middle-aged people face greater pressure from work and family, and their physical and mental strength are obviously overdrawn, which is very likely to cause autonomic nervous system disorders. If they do not pay attention to replenishing "qi" in daily life, they will inevitably be "favored" by night sweats.

Sweating at night

Sweating at night is called night sweats. Some patients with night sweats sweat as soon as they fall asleep, some sweat after falling asleep in the middle of the night, and some sweat as soon as they close their eyes for a while. The amount of sweat produced varies greatly. According to the clinical manifestations of patients with night sweats, they can be divided into three types: mild, moderate and severe.

Most patients with mild night sweats sweat easily when they are deep in sleep, at around 5 a.m., or 1 to 2 hours before waking up. The amount of sweat is small, and they only feel a little sweat all over the body or certain parts of the body after waking up, and no sweat will be secreted again after waking up. It is usually not accompanied by any discomfort.

Most patients with moderate night sweats will sweat soon after falling asleep, and their sleeping clothes may even be soaked through. The sweat will stop after they wake up, and they will not sweat again after wiping the sweat off their bodies. This type of night sweats causes the patient to feel hot and sweat, and sometimes to feel dry mouth and throat after waking up.

Patients with severe night sweats sweat easily. Shortly after falling asleep or just closing your eyes and about to fall asleep, you will sweat a lot. You will wake up after sweating, and the sweat will stop instantly after waking up. Falling back to sleep may cause sweating again. The amount of sweating is large, and the sweat often has a light salty taste, or is mixed with sweat odor. Severe sweating can make the bedding soaked, and one cannot sleep well without changing sleeping clothes several times a night. Some seriously ill patients can make the bedding soaked. When the bedding is thin or a mat is used, sweat can leave sweat marks on the bed board. These patients often have a noticeable feeling of hotness, irritability, dry mouth and tongue after sweating, and like cold water. It may be accompanied by low fever or hot flashes, fever in the five hearts, red cheeks, dizziness, weight loss, fatigue, dark urine, small urine volume, and dry stool.

For people with weak constitution, they should take dietary supplements after entering spring, eat more yin-nourishing foods, such as dates, black beans, walnuts, black sesame seeds, etc., eat more fresh fruits and vegetables, and avoid spicy and cold foods. Life should have a regular routine. The patient's bedding, pajamas, etc. should be washed or dried in the sun frequently to keep them dry and reduce the irritation of sweat to the skin.
