There are two products made for the mattress industry that will cause you to sleep hot. The most common is memory foam. The other is a terry-cloth topped waterproof mattress protector, made by Protect-A-Bed. Memory foam is now available with gel, which is supposed to sleep cooler. Note the word, "Cooler" when you see ads for this. "Cooler" than the blazes of Hell, is not cool...just cooler. The gel works, to a degree, and for a time. Gel mixed with memory foam doesn't work as well as a gel pad over the memory foam....and, the gel works for a few hours, at best. That is to say, in the middle of the night, it stops working and you are back into the frying pan. Pillowtops also contribute to sleeping hot, as you are more encompassed by the foams an the top of the mattress.

You must understand that your body goes through temperature cycles as you sleep...regardless of the materials under you. A waterproof mattress protector is a good thing. It prevents your perspiration from seeping into the mattress, which is one of the factors that cause it to wear. It best to use, either a quilted protector with a waterproof backing, or a breathable smooth top protector that is infused with bamboo. No item will prevent you from perspiring during the night. And, with a water proof mattress protector, you may feel the perspiration under you. However, with the right mattress protector, the perspiration will wick away quickly as you turn over. The major keys to sleeping as cool as possible, is to avoid memory foam and pillowtops.

There are a couple of factors here. First, waking up drenched means the moisture from your body has no ability to evaporate. That mattress has a plastic fabric covering and plastic fibers in the pillowtop: Microfiber. Plastic doesn't breath. And the mattress pad you have on it...what does the tag say the contents are? Also, what is the mattress sitting on? If you don't have a breathable base sometimes that can be a factor as well.

A couple questions I always like to ask, is did you have this problem before, what temperature do you sleep in? This may depend on the part of the country you live in. Arizona is obviously hot. Also, do you use a fan? Are you tossing and turning or staying in one position throughout the night. Also do you take a bath or shower before you got to bed, if you do the ambient temperature of your body may be warm because of your bath time. You may need some time to cool off, or just take cold showers. Do you have to many covers on? Also, how much water do you consume, are you dehydrated? And lastly do you notice more sweat when you have alcoholic beverages as opposed to nights when you don't. I know these are a lot of questions but, good sleep habits will determine good sleep. Good luck!

People in Arizona do not sleep outside. We have air conditioning.
