If Body Temperature is 37 Degrees Celsius, Why Do We Feel Hot When it’s 37 Degrees Outside?

It is well known that human body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit). However, have you ever wondered why we still feel hot when the temperature of our surroundings is 37 degrees, or for that matter, even less than that?

Heat Produced By the Body

The human body is always producing heat energy from the food that we eat. Basically, heat is a byproduct of the various functions that are performed by the tissues of the body. Therefore, it is crucial for the body to continuously emit this heat so that the temperature of the body is maintained at 37 degrees Celsius. This is the optimal temperature for the body to perform its vital functions.

When the external temperature is around 37 degrees Celsius or less, it messes with the way in which the heat-dissipation process of the body takes place. This is because when the temperature outside is in this range, the body loses heat much slower than it’s supposed to. However, the body still is producing heat as a byproduct from all the functions that it’s performing and not getting a proper, or in other words, “fast enough” outlet for the heat that is continuously being generated inside.

That’s why you end up feeling hotter than usual, even though at first glance, it doesn’t seem logical.
