Danger zone is heat exhaustion.
We are not in the danger zone yet, when it comes to high temperatures and humidity, which could cause heat exhaustion. But according to Bob Smerbeck, expert senior meteorologist for Accu-Weather, those days are coming. "Once we get into that heat index reading of 105 to 130 F, you are going to get cramps, prolonged exposure, you have to stay hydrated, that is the main thing," said Smerbeck.
Heat exhaustion is typically caused when people who are not well adjusted to heat exercise or work in a hot, humid environment. "You have to rest and find ways to cool off. You just don't want to sit there and stew in the heat, which is coming really soon," continued Smerbeck.
For heat exhaustion, a person should go to the hospital if they lose consciousness, become confused, have chest or abdominal pain, continuous vomiting, and have a temperature of more than 104 degrees.
