Once over the embarrassment of wearing what I think looks like a thinner life jacket (tip- go with khaki not royal blue...more of a fishing vest look in khaki) I rely on my cooling vest a lot. For when I am outside in the heat and also recently for traveling to Tucson for work (on my!). It's great for that 20 minutes on the airplane when they turn off the air to taxi out on the runway and wait in line! Mine has the gel packs, Coolsport, and they can even be put in a hotel sink with cold water and some ice and are good to go in 20 minutes. Last for 3 or 4 hours. And yes, you could do housework in it.
Short and quick tips- Running wrists under cold water for 5 minutes (learned in Tucson there is no cold water from pipes), splashing cold water on face neck, arms, anywhere! and letting it just air dry, a five minute cool shower when desperate, massive water to drink, I don't have A/C at home so keeping blinds and things closed up in the early part of day. (I live in the Northwest so I can survive without a/c though a bedroom one would be nice for a few weeks). Seeking out shade (and bathrooms) when arriving somewhere new, moving slower- sluglike sometimes, avoiding stress and that's all I have for now. Oh- and a frozen type of drink like old school Slurpee or a fancy Frappucino can really cool me down from the inside out. Willow
