Is cold really good for you?

No one likes Frozen ass. Therefore, when François Haman tried to recruit subjects to study the health benefits of uncomfortable temperature, he got a lot of, um…cold. He doesn’t blame them. “You won’t attract too many people,” said Harman, who studies thermophysiology at the University of Ottawa in Canada.

The human body is not good at facing the cold at all. “I have done research and people are exposed to an environment of 7 degrees Celsius [44.6 Fahrenheit], This is not even extreme. It’s not that cold. Very few people can maintain 24 hours,” he said. (These subjects even dressed neatly: “gloves, hats, boots, and socks. But they still can’t stand it.”)

People strive to stay comfortable or cool by smoothing the temperature changes in the indoor space-without shaking or sweating. It’s easy to reach the space heater or shout “Alexa, keep me warm!” The moment you feel a little discomfort. But maybe you shouldn’t make too many changes to the thermostat.Some of the reasons for the heat relief are obvious: about 47% of American House Burning natural gas for heating, 36% use electricity, in the United States, electricity is still mainly derived from fossil fuels. There may be other reasons for accepting cold—physiologists like Harman have begun to discover health factors.

Harman said that before industrialization, “these extremes were actually part of life.” The body responds to cold in winter and heat in summer. “You keep going back and forth, back and forth. This may contribute to metabolic health,” he said.

Researchers know that your body responds when it is cold. With prolonged exposure to the cold, new fat appears, muscle changes, and your comfort level will increase. But what all this means for modern human health—and whether we can use the effects of cold to improve it—is still an open question. A study sought to understand how changes in fat or muscle caused by cold can help avoid metabolic diseases such as diabetes. Another suggestion suggests that feeling comfortable in the cold is easier than you think-without heating.

For Harman, these are all useful scientific questions, because freezing is one of the oldest existential threats to our bodies. “Cold, for me, is [one of] The most fascinating stimulus, because the cold may be the biggest challenge facing humans,” he said. “Even if the heat is challenging, as long as I have water and shade, I will live well. Cold is the opposite. “

“If you can’t work together,” he continued, “if you don’t have the right equipment, if you don’t have the right knowledge – you won’t be able to survive. It’s that simple.” Figure out how our bodies are so powerful and ancient. Changes in the opponents provide clues to understand how they work and how to work better.

Harman started every Take a cold bath or shower a day. This is a rush, because cold triggers the body to release hormones called catecholamines, which are involved in the fight or flight response. “I do feel this way Oh my goodness, I feel so strong, I woke up,” he said. “This is my coffee. “
