With over two million new cancer cases anticipated this year, early detection remains a critical factor in treatment success. While many are aware of common cancer symptoms, experts are urging increased attention to a frequently overlooked sign: persistent night sweats that soak bedding and clothing. Medical professionals caution that regularly waking drenched in sweat-even in cool environments-warrants medical evaluation, as it can be an indicator of several types of cancer and other underlying health conditions.
Early detection is crucial in the fight against cancer, but recognizing the signs can be challenging given the hundreds of different types and overlapping symptoms. One often overlooked indicator, experts say, is excessive sweating that occurs overnight, soaking your sheets and pajamas.
Why Night Sweats Should Be Taken Seriously

More than two million new cancer cases are expected to be diagnosed in the United States this year, and the disease remains the second leading cause of death nationwide. This underscores the importance of paying attention to potential early warning signs.
Night sweats are frequently dismissed as a minor discomfort or attributed to room temperature. However, prolonged and intense sweating can sometimes signal a more serious underlying health issue, according to medical professionals.
“If You’re Waking Up in Soaked Sheets, Get Checked”
The United Kingdom’s National Health Service (NHS) cautions about the significance of night sweats, stating:
“Most people experience night sweats from time to time. But if you regularly wake up drenched in sweat, you should be assessed by a general practitioner.”
The NHS defines night sweats as heavy sweating that is enough to soak your pajamas and bedding, even when the room is cool.
How Cancer Can Raise Body Temperature
According to Cancer Research UK, cancer can lead to excessive or abnormal sweating as the body attempts to lower its temperature.
This can be a direct result of the cancer itself, or it may be linked to infections or treatments associated with the disease. While sweating is more common during warmer months, experts emphasize the importance of not ignoring sudden onset night sweats. Recognizing these subtle signs can potentially lead to earlier diagnosis and improved outcomes.
Check Your Pillow and Sheets in the Morning
Healthcare professionals recommend checking your bedding each morning. While you may not immediately notice excessive sweating upon waking, wet hair, damp pajamas, or visible sweat marks on your pillow can be important clues.
If you’re unsure whether you’ve been sweating excessively during the night, the Mayo Clinic defines night sweats as “repeated episodes of heavy sweating that soak your clothes or bedding during sleep.”
Which Cancers Are Associated with Night Sweats?
Night sweats alone are not necessarily indicative of cancer, but they are more frequently observed in certain types of the disease. These include:
- Kidney cancer
- Bone cancer
- Prostate cancer
- Leukemia
- Non-Hodgkin lymphoma
Therefore, it is recommended to consult a healthcare professional for persistent, unexplained night sweats that interfere with daily life. Early evaluation can help determine the cause and ensure appropriate care.
