Tuberculosis is the infection most commonly associated with night sweats. But bacterial infections, such as endocarditis (inflammation of the heart valves), osteomyelitis (inflammation in the bones), and abscesses can cause night sweats. Night sweats are also a symptom of HIV infection.
Most infections can cause a high temperature (fever) with some sweating, and therefore any infection can cause night sweats.
The flu, COVID-19, and any other infection that causes a fever can lead to cold sweats. Sometimes they occur as a fever "breaks" or starts to go back down. If an infection progresses and enters the bloodstream, the body may go into septic shock.
Night sweats can be a manifestation of simple infection, underlying malignancy, more complex infections – including TB and HIV – connective tissue disorders, menopause or certain prescribed drugs. It's also important not to overlook possible psychological causes, such as night terrors secondary to PTSD.
If your night sweats occur on a regular basis, interrupt your sleep, or are accompanied by a fever or other symptoms, such as unexplained weight loss, then you should schedule an appointment with your physician.
Viral and bacterial infections, such as the flu, strep throat, or COVID-19 can cause a fever. When your body temperature increases, it needs to cool down to prevent it from overheating, so you get chills and cold sweats.
Some infections are known to cause night sweats. That's because any type of infection—whether it be bacterial, viral,6 or fungal—can cause a fever, which is triggered when the part of your brain that governs body temperature (your hypothalamus) causes your internal temperature to rise, the Mayo Clinic explains.
(DREN-ching …) Episodes of excessive sweating that occur during sleep and soak a person's bedclothes and bed sheets, which may cause the person to wake up.
Most people who have night sweats are worried that they indicate some serious underlying disease. But night sweats are quite common and, for the vast majority of people, don't represent a medical concern.
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. Leukemia-related sweats may also result from daytime fevers.
The core clinical symptoms are always the same: severe fatigue made worse by exercise, myalgia, night sweats, atypical depression and excessive sleep. The other common symptoms include dysequilibrium disorders and irritable bowel syndrome.
Night sweats are also associated with colds, the flu, COVID-19, HIV, and some bacterial infections (endocarditis, osteomyelitis and pyogenic abscess). Night sweats, like hot flashes, are often related to hormone changes that make it harder for your brain to regulate your body temperature.
That said, common causes identified in research about night sweats include menopause, medications, infections, and hormone problems.
Sometimes, the balance between hot and cold is thrown off to the point where these thermoregulation processes cause us to wake up. Waking up shivering cold or hot and sweaty is never a comfortable experience. This can happen due to the sleep environment being too cold or too warm.
If a history and physical do not reveal a possible diagnosis, physicians should consider a purified protein derivative, complete blood count, human immunodeficiency virus test, thyroid-stimulating hormone test, erythrocyte sedimentation rate evaluation, chest radiograph, and possibly chest and abdominal computed ...
Some signs of leukemia, like night sweats, fever, fatigue and achiness, resemble flu-like symptoms. Unlike symptoms of the flu, which generally subside as patients get better, leukemia symptoms generally last longer than two weeks, and may include sudden weight loss, bone and joint pain and easy bleeding or bruising.
Infections
Occasionally, your body produces night sweats because it's trying to heal itself.
A viral infection usually lasts only a week or two. But when you're feeling rotten, this can seem like a long time! Here are some tips to help ease symptoms and get better faster: Rest.
It's normal to sweat during the night if the room or your bedding is making you too hot. Night sweats are when you sweat so much that your night clothes and bedding are soaking wet, even though where you're sleeping is cool. Adults and children can get night sweats.
Sweats can happen at any time of the day with lymphoma, but they are most common at night. They are often described as 'drenching' and can make your nightclothes or bed sheets soaking wet.
Hypoglycemia
Hypoglycemia refers to low blood sugar levels. Glucose is the primary source of energy for your cells. Low blood sugar affects the functionality of vital organs such as the brain. Nausea and heavy sweating are among the warning signs of hypoglycemia.
