I don't want to alarm anyone, but night sweats can be a sign of illness.
If this is a new symptom for you, and you haven't been feeling well, or
you've lost a lot of weight without really trying, you ought to get
cheked out.  If you've done it all your life, I wouldn't worry about it,
but night sweats are among the sypmtoms you shouldn't just shrug off.
