What does night sweat mean?
I am 30 years old this year, and I always feel excessive sweating during sleep at night. I heard from others that this is called night sweats. I would like to know, what does "night sweats" mean?

Night sweats, medically referred to as "nocturnal hyperhidrosis," refer to abnormal and excessive sweating during sleep, especially within the initial period after falling asleep. Common causes of night sweats include:
1. Excessive heat: Overheating due to excessive bedding or a high environmental temperature.
2. Neurological disorders: Such as autonomic nervous system dysfunction.
3. Hormonal imbalances: For example, menopausal syndrome, hyperthyroidism, etc.
4. Cardiovascular diseases: Such as heart failure.
5. Cancers: Certain malignant tumors, such as lymphoma and leukemia.
If symptoms persist or worsen, it is recommended to seek timely medical evaluation.
