Some people with OI (orthostatic intolerance), POTS (Postural Orthostatic Tachycardia Syndrome), etc. do better in warm weather and others so better in cold weather.
Increased humidity, poor air quality and heat have very negative effects on the two patients I know best.
A friend gave us the following list of links to some cooling products*:
We were pleased to discover that the cooling vests and neck wraps do indeed make a difference for our household (even indoors).
Consider the humidity levels of your area.
If high humidity is frequent in your area, products that use freezer/gel packs (while more expensive) cool much more effectively than evaporative products.
Sue J supplied a link to a blanket (thanks):
And a pillow:
Absorber cloths cut into long strips that you just dunk into cold water. They don’t get as warm as the fatter neck cloths and they’re not heavy. (thanks SHW)
* This list is a sampling of sites that have these products. Send us links that we can add to this list.
