Diagnosing Night Sweats

To diagnose night sweats, your doctor will first take a medical history and perform a physical exam. They may ask questions about your symptoms, medical history, and any medications you are taking. They may also order blood and imaging tests to rule out underlying medical conditions.

Treatment of Night Sweats

The treatment for night sweats depends on the underlying cause. If night sweats are caused by an underlying medical condition, such as an infection or cancer, treating the underlying condition will often alleviate the night sweats. If medications cause night sweats, your doctor may adjust your medication or prescribe a different medication.

If there is no underlying medical condition causing the night sweats, several self-care measures can help alleviate the symptoms. These include:

  • Keeping the bedroom cool and well-ventilated
  • Using light bedding and sleepwear
  • Avoiding spicy foods and alcohol
  • Practicing relaxation techniques, such as meditation or deep breathing exercises

If self-care measures are ineffective, your doctor may prescribe medications to help control night sweats, such as hormone replacement therapy, antidepressants, or anticholinergic drugs.

Preventing Night Sweats

There are several things you can do to prevent night sweats, including:

  • Avoiding triggers such as spicy foods, alcohol, and caffeine
  • Staying cool during sleep by using light bedding and sleepwear
  • Practicing good sleep hygiene, such as going to bed and waking up at the same time each day
  • Managing stress and anxiety through relaxation techniques, exercise, and counseling.


Night sweats can be a symptom of an underlying medical or standalone condition. They can be uncomfortable and disruptive experiences that interfere with sleep and quality of life. If you are experiencing night sweats, it is essential to talk to your doctor to rule out any underlying medical conditions and develop a treatment plan for you. With proper diagnosis and treatment, you can get rid of the issue.
