What does it feel like to sleep and sweat when it's cold?

Night sweats literally mean sweating when you don't know, mostly while sleeping. The light one may just have a little sweat, and the heavy one may have soaked clothes and quilts. So English is also called night sweats. Japanese is called Sleeping Khan, which follows the old saying of China and is more direct and clear.

What is the cause of night sweats? Is it because of "weakness"?

Whether it is night sweats or not, we must first rule out whether the sleeping environment is overheated. If the room temperature is too high, or it is covered too much, for example, many newborns, parents are afraid that their children will be cold and wear too many clothes (this is a very common bad habit in China), so sleeping and sweating is not considered night sweats. Just lower the room temperature, wear less clothes and cover it thinner. Real night sweats can lead to skin redness, sweating, and even sweating when sleeping at night, even in an environment that is not too hot. This is called night sweats.

There are many reasons for night sweats. If you want to determine the cause, you need to know the detailed medical history and do some related tests. Some people can find the reason, but a large number of people can't. The following are the main reasons.

1. Menopause. Postmenopausal women will sweat more than usual, especially at night, due to the drastic changes of hormones in the body and the expansion of blood vessels on the skin surface. About two-thirds of menopausal women will have night sweats.

2. infection. Some infections can cause sweating at night. The most common and well-known is tuberculosis infection. Night sweats are one of the characteristics of tuberculosis infection. But other infections can also cause night sweats. For example, endocarditis (endocarditis, heart valve infection), osteomyelitis (bone infection) or abscess in the body can also cause night sweats. People infected with HIV may also have night sweats.

3. Malignant tumor. The early manifestations of some malignant tumors may be night sweats and weight loss. The most common causes of night sweats are lymphoma and leukemia. But usually night sweats caused by malignant tumors do not appear alone, and most of them have weight loss and low fever.

4. Drugs. If you are taking certain drugs, some drugs will cause excessive sweating, which is manifested as night sweats. The most common is antidepressants. One of the side effects of almost all antidepressants is night sweats. About 8% to 22% of the patients taking this medicine have night sweats. For example, commonly used tricyclic antidepressants, selective serotonin reuptake inhibitors (such as Baiyoujie), venlafaxine, bupropion and so on. There are other drugs for mental illness that can also cause night sweats. In addition, antipyretics can also cause night sweats. Such as common aspirin and p-acetylsalicylic acid. There are also some drugs that can easily cause skin redness and night sweats, such as nicotinic acid, which is vitamin B3. Hypoglycemic drugs also often cause night sweats.

5. Hypoglycemia. Many times, night sweats can also occur due to hypoglycemia at night. For example, after taking insulin or oral hypoglycemic drugs before going to bed, diabetic patients will have hypoglycemia and sweat a lot during sleep.

6. hormonal imbalance. Some diseases with abnormal hormone levels can lead to night sweats. For example, pheochromocytoma (excessive production of catecholamine by adrenal gland), carcinoid syndrome and night sweats in patients with hyperthyroidism are also common.

7. Nervous system diseases. This disease is not common, and there are not many cases that cause night sweats, but there are still. Such as abnormal autonomic reflex, posttraumatic syringomyelia, cerebral infarction and autonomic neuropathy.

The causes of night sweats mentioned above are all caused by some diseases or special physiological conditions, but in fact most people with night sweats belong to one kind of primary hyperhidrosis. The so-called primary disease in medicine refers to the physical manifestations with no clear cause, that is to say, primary hyperhidrosis does not have the above diseases, but sweats more at night.
