Night sweats can be caused by various medical conditions including cancers, hormonal imbalances, infections, and medication side effects. Recognizing symptoms and seeking medical advice is important for proper diagnosis and treatment. Lifestyle adjustments can provide relief but persistent symptoms require professional evaluation.

Experiencing excessive sweating during sleep, known as night sweats, can interfere with rest and may signal underlying health concerns. Common triggers include certain cancers such as lymphoma and leukemia, which often present early through intense nocturnal perspiration. Medications can also induce night sweats as a side effect. Infections like abscesses or tonsillitis may contribute, along with neurological issues like stroke or autonomic neuropathy. Hormonal disturbances from hyperthyroidism or carcinoid syndrome, as well as idiopathic hyperhidrosis without a clear cause, are other factors. Persistent night sweats accompanied by weight loss, fever, or worsening symptoms warrant medical attention.

Management depends on the root cause; hormone therapy may help menopause-related sweating, while infections require targeted treatment. Lifestyle modifications, such as wearing lighter clothing and using air conditioning, can alleviate mild cases. Consulting a healthcare professional is crucial for ongoing or severe symptoms.
