Good Morning! It's 76°F at 8:00am. I wish the temp would stay like this all day, but the heat index will rise to 100°F. Heat index of 100°F means we are in trouble if we're in it. Above 98.6°F heat index ( wet bulb temperature), the human body can no longer release waste materials and toxins through sweating. Our bodies become poisoned. We can die. Take care
