Heat Index Calculator
The heat index or humiture or humidex temperature is the temperature felt by the skin rather than the actual temperature due to the humidity level. In hot temperature, the human body normally will sweat and heat is removed from the evaporation of the sweat. The Humidity level of the environment will affect the evaporation rate, which will affect the heat removing rate and the temperate the skin feels. On the opposite, wind will bring more heat away from human body. Therefore, the body will feel a lower temperature than the actual temperature in a windy winter day. Use the wind chill calculator to evaluate the actual temperature in the winter.
Heat Index Temperature: 93°F or 34°C or 307°K
Humidity Level: 55%
Typical Heat Index Values
In the desert, it is hot and dry. By the sea, in the tropics, it is hot and wet. Many of us find it easier to support hot and dry climates than hot and wet ones. Hence the phrase: "It's not the heat, it's the humidity".
The Heat Index Calculator pulls together heat and humidity, to measure not just how hot it is, or how wet it is, but how the climate really feels to you. This is sometimes referred to as the 'apparent temperature'.
The effect of the 'apparent temperature' on how you feel can have medical significance. When it is hot and wet, perspiration is hindered, because you begin to perspire, but the sweat doesn't evaporate. The purpose of sweating is to cool you off, and when the sweat doesn't evaporate, you don't get cooler. So you can get sick from the heat.
This means that care must be taken in humid conditions to avoid overheating and dehydration. This is particularly important for children. Young children are in more danger from both for several reasons. They have a larger skin surface relative to their small bodies, so they absorb more heat from the sun and air. When they exercise, they produce more heat. And because they don't sweat as much, their bodies don't cool off as well. Also, they get so focused on playing that they aren't aware that they need to rest, cool off and drink liquids.
Make sure your child is well hydrated before, during and after outdoor activities. Beginning about 30 minutes before the activity, have the child drink 4 to 8 ounces of liquid. During the activity, have him take breaks every 20 minutes to drink liquids: approximately 4 ounces for a younger child and 8 ounces for a teen-ager. Your child should drink whether or not the child feels thirsty, since thirst is a late sign of dehydration. Water, diluted fruit juices and sports drinks are all fine, but flavored drinks help encourage children to drink more. After the activity is over, have the child drink another 4 to 8 ounces.
People with certain medical conditions, including obesity, diabetes, heart disease, cystic fibrosis and mental retardation are at even greater risk for overheating and dehydration.
Such people should try to spend as much time indoors as possible on very hot and humid days. Use your stove and oven as little as possible and use fans and air conditioners to cool off your home. If your home does not have air conditioning, go to an air-conditioned shopping mall or public library. Have your child wear as little clothing as possible. Consider taking the time to give the child a cool bath or shower.
