Be careful if spending time outdoors, especially when grilling or at a picnic, try sitting in the shade when you can and drink extra amounts of water. If you are working, or exercising outdoors do not over do it! Be sure to take several breaks when you can, and if possible stay in Air Conditioning during that break as well.
