Sleeping in a bedroom that is too warm, wearing too many layers, or covering yourself with too much bedding can cause you to sweat at night. There are a number of other potential causes of night sweats: Infection: Bacterial and viral infections often cause fevers, and sweating frequently occurs with a fever.
Night sweats may occur with any condition causing fever. Although suggestive of tuberculosis or lymphoma, they also occur in brucellosis, lung abscess, bacterial endocarditis, diabetic autonomic neuropathy, nocturnal hypoglycemia, nocturnal angina, and diabetes insipidus.
Cold sweats can be caused by a number of factors—anxiety, pain, hormonal fluctuations, low blood sugar, or infections, he says. On the serious side, cold sweats can signal a condition, like cancer, especially when you're sweating at night. Sudden sweating can also be one of the first signs of a heart attack.
If your symptoms occur often or do not resolve with changes in your bedroom temperature and bedding, it's a good idea to speak with your doctor. Your doctor will collect information from you about the frequency and severity of your shivering or sweating, along with other related symptoms.
In hot weather or following physical exertion, perspiration represents the body's normal response to cool itself down. Cold sweat, where perspiration breaks out for no normal reason, can be a heart attack alarm.

Night sweats can be linked to cancer and certain cancer treatments: Lymphoma. Leukemia. Carcinoid tumors (usually in your digestive tract)
Drenching night sweats that require changing clothes are more concerning than mild night sweats. Leukemia and lymphoma are among the cancers associated with night sweats. Those associated with leukemia usually occur in conjunction with symptoms such as fatigue, weight loss, or excessive bruising.
Hyperthyroidism. Hyperthyroidism, also called an overactive thyroid, is a condition in which excessive thyroid hormone is made by the thyroid gland. Hyperthyroidism increases a person's metabolism, which can cause the body's temperature to go up and trigger excess sweating .
There are several common reasons for night sweats – from spicy foods to warm bedrooms – but excess sweating can be a sign of a medical condition such as an infection, menopause or cancer. “Just being hot at night should not worry anyone,” says Dr.
Common signs and symptoms for COVID-19 and flu include:
Muscle aches. Chills and sweats. Shortness of breath or difficulty breathing. Dry, persistent cough.

There are many of these conditions, and some—lupus, to name one—can cause night sweats, Danoff says. Rheumatoid arthritis and Celiac disease are two others.
Having night sweats a few times is usually nothing to worry about. But talk to your doctor if you often have night sweats or you have other symptoms along with them. These might include fever, chills, pain, or unplanned weight loss.

Night sweats: Rarely cause for concern
“Almost any kind of infection can cause night sweats,” she says. This includes kidney infections and much rarer infections like tuberculosis. In other cases, the cause may be thyroid or liver disease, or a sleep disorder like obstructive sleep apnea.
Sometimes, excessive sweating from the head and face can be put down to a medical condition called craniofacial hyperfidrosis, which is caused by overactive sweat glands.
Fever, chills, and night sweats are common symptoms that can accompany a wide variety of medical conditions, including respiratory infections like influenza, sinusitis, or viral sore throat (pharyngitis). These symptoms would typically be accompanied by other symptoms as well.
