Also from a few doctors around here.
Night sweats can be caused by your body trying to fight off a common illness (cold/infection) but also if you workout hard and exhaust yourself, it could be your muscle regeneration process or the process to repair something you over exerted. So apparently if you do Cathe your going to be prone to night sweats. So maybe that will make those who feel too young to be having hotflashes, not feel so old now). ;-)
Also if your normally a heavy sweater, you just take that to bed with you, so even a light sheet, if you produce too much heat, you sweat.
But also this could be a very serious condition, so start keeping a diary and writing down when this occurs and what you've done recently. Here is a quote form Dr.Marks, "There are also several relatively serious conditions that can trigger night sweats. These include tuberculosis, hepatitis, immune system disorders, thyroid disorders, leukemia, strokes, bowel disease and heart disease."
And here are some suggestions:
"Any time you have sweating, you need to increase your water intake to replenish what is lost," He recommends at least 12 glasses per day (4 more than the average person requires) at room temperature to cool down your core temperature without shocking the system. Drink one glass just before going to bed. Showering or sponging with cool (not cold) water can also lower core temperature to inhibit some sweating. But if your experencing night sweats do drink more water.
"Don't take part in heavy physical activity before going to bed," This will only increase your body's core temperature and can serve as a spark to ignite sweating later in the night." Stay away from hot tubs, showers and saunas at night, too.
"You shouldn't have a completely full stomach at bedtime, A midnight snack will just lie in your stomach all night, making you uncomfortable and thus producing sweating. Spicy foods and hot beverages can also bring on some severe night sweating."
"Say no to nightcaps, that late-night cocktail, coffee or cigarette can raise your pulse, blood pressure, body temperature and adrenaline levels, says Dr. Greene. It's an open invitation for a difficult, if not sweaty, night's sleep."
Also Keep a sleep log. If you are at a loss to explain what could be causing your night sweats, Note anything relevant before you went to sleep, such as what you wore or the room temperature, what you did that day, and that evening. What you ate, and how full you were before you went to sleep. When you wake, jot down anything you can remember during the night, how you feel and the condition of your bed. Continue logging the information for a few weeks—you may see patterns emerging that can give your doctor a better indication of the cause.
Hope that helps,
