Know Your Self For Real
Hot & Cold: Extreme Temperature Safety If you intend to travel outdoors, you should be prepared to deal with all sorts of weather. This might mean the rainiest days to the driest, and from the hottest daytime hours to the coldest nights.
The human body has a normal core temperature between 98.6 and 99.9 degrees Fahrenheit (F). In order to maintain this temperature without the aid of any warming or cooling device, the external environment must be at about 82 F. Clothes aren’t just a social convention — they’re necessary warming tools. We can usually add on more layers in colder months, and use fans or air conditioners in warmer months in order to maintain that healthy core temperature.
However, in some cases, you may find yourself in an environment with temperature extremes. It’s essential to know what health concerns you may face, and how to avoid any temperature-related problems.
Part 2 of 3: The Heat
The HeatIt’s important to note that the temperature reading on a thermometer is not necessarily the temperature for which you should be concerned. The relative humidity in an environment can significantly affect what’s called the “apparent temperature,” or the temperature you actually feel. If the air temperature reads 85 F, but there’s zero humidity, it will actually feel like it’s 78 F, whereas the same air temperature in an environment with 80 percent humidity will feel like 97 F.
High environmental temperatures can be dangerous to the human body. In the range of 90 to 105 F, heat cramps and exhaustion may occur. Between 105 and 130 F, heat exhaustion is almost certain, and activities should be significantly limited. An environmental temperature over 130 degrees F is likely to lead to heatstroke.
Heat-related illnesses include:
The ColdAs with high temperatures, when it comes to cold temperatures, don’t rely solely on the thermometer reading of environmental air. For instance, the speed of the wind and external body moisture can cause a chill that dramatically changes your body’s rate of cooling and how you feel. In very cold weather, especially with a high wind-chill factor, you can rapidly experience the onset of hypothermia. Falling into cold water can also result in immersion hypothermia.
When your body first drops below 98.6 F, you may:
It’s essential to protect anyone experiencing early symptoms of hypothermia. They should be removed from the cold immediately if possible. However, don’t try to warm a person suffering from serious hypothermia with vigorous exercise or vigorous rubbing, because this can lead to more difficult problems.
Other cold-related illnesses include:
Proper preparation and attention to emerging conditions can prevent or treat many temperature-related situations and ailments.
