The idea that our body temperature is a steady 98.6°F (37°C) originated with a German physician named Carl Reinhold August Wunderlich, who back in the 19th century, took the temperatures of thousands of patients and came up with this average number. But, what he didn't realize (or maybe he just didn't care) was that this number is not as universal as he thought - it can vary depending on all sorts of factors, like the time of day, your age, and even your mood.
For example, did you know that your body temperature can rise and fall throughout the day, with the highest temperatures usually occurring in the late afternoon? Or that women's body temperatures can fluctuate depending on their menstrual cycle? It's like your body is playing a game of temperature tag, and the rules are always changing.

And then there are the extremes - people who can withstand temperatures that would be fatal to the rest of us, like the Tibetan monks who can raise their body temperature through meditation, or the Wim Hof types who can withstand freezing temperatures with ease. These people are like the temperature superheroes of the world, and we can only marvel at their abilities.
