What Is A Heat Wave?
A heat wave is an extended time interval of abnormally and uncomfortably hot and unusually humid weather.
To be a "heat wave" such a period should last at least one day, but conventionally it lasts from several days to
several weeks.

What Is The Heat Index?
The heat index is the "apparent temperature" that describes the combined effect of high air temperature and
high humidity. The higher this combination, the more difficult it is for the body to cool itself. If you work
outdoors, it is critical that you remain aware of the heat index and take the appropriate precautions.

    Symptoms include painful spasms usually in leg and abdominal muscles, and heavy sweating, First Aid
    measures include firm pressure on cramping muscles or gentle massage to relieve spasm. Give sips of water.
    If nausea occurs, discontinue.
