Re: seizure meds. and heat sensitivity
Isn't Trileptal a variant of Tegretol (chemically)?
Teg is known for causing patients to be sensitive to sun exposure, mainly burning easially.
With ANY medications keeping hydrated in sumer conditions is needed. Even for healthy persons not on medications. Dehydration can come easially. Taking frequent breaks, drinking a lot of WATER (NOT soda, NOT energy drinks) helps when being exposed to sun and hot environments. It will keep your system hydrated. Breaks (shade, or inside if you can) help. Going into an air conditioned environment may cause **shock** to the system, so be carefull when doing that depending on the temp change from outside to inside.
LIGHT colored clothing (natural, not synthetic so it breathes) so it reflects light not absorbes it long sleeve THIN if you want to try and cover up your arms; otherwise stay with short sleeve. And the tips from the previous post.
I'd also sugest one of the many commercial products you can find in sports stores. Water back packs, or similar ones. A good way to keep water on you that you can drink through a tube (bite and drink). In hot temps fill them half way with ICE and the rest with water to make sure they stay cool if you intend to be out long.
Just came to my mind... Beach umbrella for larger area of shade. Won't really bump down the ambient temp, but will provide shade and make it "feel" slightly cooler without the direct sun beating down on you.
