Overview
Night sweats refer to episodes of excessive sweating during sleep that can soak clothing or bedding. Unlike normal perspiration caused by warm environments, night sweats are often unrelated to temperature or physical activity and may indicate underlying medical conditions.
In Korea, physicians carefully evaluate night sweats to identify potential causes, ranging from infections, hormonal imbalances, medications, to systemic diseases. Timely diagnosis is crucial to prevent complications and guide appropriate treatment.
Key Facts
➤ Night sweats are episodes of excessive sweating during sleep, not caused by heat or exercise.
➤ They can affect men, women, and children.
➤ Causes range from infections, hormonal changes, medications, and cancers to less serious conditions.
➤ Recurrent night sweats may interfere with sleep quality and daily functioning.
➤ In Korea, comprehensive diagnostic evaluations are available to determine the underlying cause.
What are Night Sweats?

They are a symptom rather than a disease, signaling potential health issues that require evaluation.
Symptoms Related to Night Sweats
➤ Excessive sweating during sleep, sometimes soaking pajamas or bedding.
➤ Chills or shivering accompanying sweating.

Causes / Possible Causes
Night sweats can result from infectious, hormonal, malignant, or medication-related factors:
Infections
➤ Tuberculosis – classic symptom is prolonged night sweats.
➤ HIV/AIDS – may cause persistent night sweating.
➤ Bacterial infections such as endocarditis.
➤ Viral infections like influenza or mononucleosis.
Hormonal Causes
➤ Menopause – due to fluctuating estrogen levels causing hot flashes.
➤ Hyperthyroidism – excessive thyroid hormone increases metabolism and sweating.
➤ Diabetes – hypoglycemia during sleep may trigger sweating.
Malignancy
➤ Lymphoma – particularly Hodgkin’s lymphoma, often presents with night sweats.
➤ Other cancers may also cause systemic symptoms including weight loss and fatigue.
Medications
➤ Antidepressants, steroids, and fever-reducing drugs may induce night sweats.
➤ Certain hypoglycemic medications in diabetics can cause nocturnal sweating.
Other Causes
➤ Anxiety or stress-related sympathetic activation.
➤ Obstructive sleep apnea leading to nighttime sweating.
➤ Idiopathic causes, where no clear reason is found.
Risk Factors
➤ Middle-aged or older women, particularly during menopause.
➤ Individuals with thyroid disorders or diabetes.
➤ Patients on certain medications such as antidepressants or hypoglycemics.
➤ People with chronic infections or immunocompromised conditions.
