#2 What is the highest and lowest temperature at which humans can survive?
The human body is designed to withstand very low temperatures. Most people can survive for short periods of time in freezing water, with the most common example being a dunking in an ice-cold swimming pool. While this is usually harmless, it can cause frostbite or hypothermia if one goes swimming or playing in cold weather without adequate protection or clothing.
The normal human body temperature is 98.6 degrees Fahrenheit, or 37 degrees Celsius. When your body temperature falls below this amount it's called hypothermia, and you can die from it and anything above is referred to as fever which is fatal and can result to hypothermia in a heat wave condition. Prolonged exposure makes burns or scalds possible at very high temperatures above 140 degrees Fahrenheit. Humans have a higher tolerance for cold than heat due to their natural response mechanism, which produces more body heat by shivering outside in cold conditions. The body’s ability to regulate temperature also depends on how much heat it can produce, which is why most people feel colder when wet or wearing little clothing.
The greatest temperature at which a healthy person may survive is around 41–42°C (106°F). 689
Heat stroke can happen at this temperature, which can seriously harm the brain and other essential organs. Low temperature: About -32°C (-26°F) is the minimum temperature at which a person can endure. Due to their innate reaction mechanism, which causes them to shiver more when it's chilly outdoors, individuals have a higher propensity for cold than heat.
It's crucial to remember that these ranges are only general recommendations and that particular circumstances might affect both the period needed for survival as well as the precise degree needed to inflict injury. For instance, small children and older adults are more prone to ailments brought on by the extremes of temperature. For instance, if you're not adequately protected, it's basically impossible to survive outside for long periods of time without dying from hypothermia. For example, being outside in shorts during -40C wind chill would be dangerous if you haven't done anything to prepare yourself beforehand. On the other hand, if you're outside wearing proper gear such as a jacket and gloves and boots, then staying outside for an hour or more won't cause much harm to you or your body; only minor discomfort will ensue. 689
