|EFFECTS OF HEAT INDEX IN OUR BODY|
|T in Celsius||T in Fahrenheit||Heat Index (Human Discomfort Index)|
|27 – 32°C||80 – 90°F||Caution Fatigue is possible with prolonged exposure and activity. Continuing activity could result heat cramps.|
|32 – 41°C||90 – 105°F||Extreme Caution Heat Cramps and Heat exhaustion are possible. Continuing activity could result heat stroke.|
