Wear cotton clothes Stay in the shade or where you have AC drink lot's of water. Eat salads and grilled protein Exercise in am before it get's hot

Wear as little as possible get in the pool as often as possible and switch on the aircon when possible

Hello I say do not go into the heat IF you don't have too, if you do always take water with you wear light weight clothes ,sunglasses, hat if you like sunscreen.& Be safe out in this heat. Just cos we are over weight does not mean that we over heat more then anyone else. for some reason people think that over weight folks tends to sweat or over heat quicker then someone who is not. I hope this helps.

wear loose clothing... drink LOTS of water

Stay hydrated, try to stay out of the heat during the worst part of the day, wear comfortable light weight clothing, and listen to your body when it gives you signals to rest. Dizziness can be one of those signals. Also don't rely of thirst as a sign that you are getting dehydrated as that can be a late sign that you are already dehydrated.
