When the daily high temperature becomes to be too high and the overnight low does not provide relief to those without adequate air circulation the National Weather Service steps in to issue a *HEAT ADVISORY* in hopes that this will remind folks that the dangers are real and present.
A *HEAT ADVISORY* means citizens should be advised that continued exposure to daily temperatures outside can result in a number of heat related illnesses including but not limited to heat stress, heat stroke and even death.
The actual technical requirements of a *HEAT ADVISORY* are as follows: For a period of 48 hours (2 days) the daily high temperature heat index (what it feels like) must reach 105-109 and the overnight low heat index must remain at or above 75 degrees.
In addition according to the National Weather Service a *HEAT ADVISORY* means: A PERIOD OF HOT TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND HIGH HUMIDITY WILL COMBINE TO CREATE A SITUATION IN WHICH HEAT ILLNESSES ARE POSSIBLE. DRINK PLENTY OF FLUIDS...STAY IN AN AIR-CONDITIONED ROOM...STAY OUT OF THE SUN...AND CHECK UP ON RELATIVES AND NEIGHBORS.
The National Weather Service issued a *HEAT ADVISORY* for a majority of Texoma including Wichita Falls and Lawton late on Monday afternoon to be upt into effect at 12 noon on Tuesday until 7pm Wednesday evening.
When folks without adequate ventilation try to survive under these conditions it will put undue heat stress on their bodies and their bodies will not be able to cool off at night to allow them to fight back during the days maximum heating.
This allows the body to over heat and heat illnesses ensue. Here are examples of heat illnesses:
Heat Stroke: is a heat illness defined as a body temperature of greater than 40.6 °C (105.1 °F) due to environmental heat exposure with lack of thermoregulation. People with heat stroke will experience a lack of persperation and be highly confused. If treatment is not administered within a certain amount of time death can occur.
In addition, never leave a child, elderly person or pet in a vehicle during high heat over 80 degrees, but especially over 100 degrees.
