Go to HEAT.gov for all the information you may need for areas of the US that are in an extreme heat phase, and for information on signs of heat exhaustion or stroke.
Remember, the heat index is the temperature and the humidty: the higher the humidity, the lower the temperature at which you could experience heat exhaustion or stroke. See chart below.
Also, see a table and downloadable health information on a previous post: https://walkearth.org/2024/04/30/extreme-heat-how-to-measure-health-risk/
Replace Electrolytes
Emergen-C packets or tablets are great to replenish electrolytes that are lost in sweating. Just add to your water bottle on very hot days and keep a few packets in car, purse, etc. Groceries and pharmacies carry these. Walmart, Walgreens, etc.
Watch out for children and seniors who are most vulnerable to a high heat index. Also, watch out for your pets.

Yes, I understood that. If you look at the chart, with a near 55 humidity reading, a temp in the high 80s or nineties goes into the Danger and Extreme Danger zones. Do you have a generator? Make sure it is ready to go.
