1. **Night Sweats**
Sweating heavily during sleep, often soaking clothes and sheets, may be due to hormonal changes or infections. However, “certain malignancies, such as lymphoma, are known to produce night sweats.” If they occur frequently with fever or weight loss, seek medical help.

2. **Unexplained Pain or Discomfort**
Persistent pain, especially in the back or joints, that worsens at night can be due to musculoskeletal problems. But can:cer may also be a cause, as it can lead to “nerve compression or bone involvement.” See a doctor if the pain interferes with sleep or doesn’t improve with basic treatment.

3. **Difficulty Breathing or Chest Tightness**
Feeling breathless or suffocated when lying down can be linked to sleep apnea, heart issues, or lung disease. In serious cases, “tumors pushing on the airway” may be the cause. If breathing problems persist or worsen, get immediate medical attention.

**What to Do**
Track your symptoms, get early medical evaluation, and maintain a supportive sleep environment.
