Freeze a small bottle of water and take it to bed with you. You will have a cold drink when you wake up drenched in sweat and hot! Also you can use the bottle like a hot water bottle in reverse!
A new range of nightwear that uses wicking fabric first developed for athletes has been launched in the UK under the label www.coolsleepwear.co.uk.
I've worn them for several weeks and find them really effective and reduced the disruption to my sleep.
My horrific nightsweats and hot flushes, running off my nose and chin were completely cured by HRT, came back when I stopped taking it, and were then completely cured by acupuncture. Being hormonal, they come from inside, so I doubt if cool nightwear (which sounds marvellous!) will actually have any effect.
I remember reading some time ago in a magazine about a product called the Chillow. It's a pillow that somehow keeps cold at night. I mentioned it to a friend whose mother was suffering from night sweats and she said it was brilliant. Here's a link to the website http://www.chillow.co.uk/whoneeds.php
They make a natural pillow from Buckwheat Hulls.
It stays cool. Has a sturdy feeling, and is actually much more comfortable then my down pillow!
They can get rather expensive though.
My Dr. told me to take soy capsules or eat more things with soy (edamame, soy milk, etc.) to deal with night sweats and hot flashes specifically. He also advised vitamins E and D as well as calcium. It's a bit of a pain to remember to take all of those but so far it's really paying off.
The wicking pjs/nightgowns and other things like running a fan, keeping the air conditioner set lower at night, changing your sheets to a lighter-weight all natural fabric, and having a glass of water by your bed will help because, while the nightsweats are caused by internal fluctuations, the trouble is with the symptoms. So, if you can control the outside of your body, you'll feel better--the same way we take medication for cold symptoms even though the thing itself isn't curable. Also, taking soy pills or eating more soy products helps, too.
Just my opinion but I tried the chillow pillow because i get really hot in the night - It just didn't help at all! at first yes it was nice and cold when i first got in bed but then i woke up several times in the night and the pillow with my body heat had gone horribly warm and i was more hot than other nights because it was like lying on a hot water bottle. I ended up throwing it off after id woken up again.
I sent it back for a refund. They're expensive too! i don't think they're worth it.
If you're going the non-HRT route, have a saliva test done to see if the hormone that's giving you trouble is progesterone or estrogen. In my case, my progesterone level went way down and progesterone is what regulates estrogen levels. So my estrogen fluctuated like mad and caused my menopausal symptoms. I started taking natural progesterone cream (brand I use is Emerita - I like Kokoro as well) and it really helped with the hot flashes and night sweats. Emerita makes a natural estrogen cream as well if that is what you need. These creams don't eliminate the symptoms but they reduce them noticeably.
