Is lifespan related to body temperature? Is it true that the cooler the body, the longer its lifespan?

The relationship between lifespan and body temperature has always been a topic of concern for people. Sometimes, we may hear some statements, such as "the cooler the body, the longer the lifespan"

The relationship between lifespan and body temperature has always been a topic of concern for people. Sometimes, we may hear some statements, such as "the cooler the body, the longer the lifespan". Is this statement correct? In fact, although in some cases, body temperature may be related to lifespan, this is not always the case.

In a 2015 study, researchers found that simulating a "low temperature" state by lowering the body temperature of experimental animals can indeed extend their lifespan. However, this relationship is not absolute, as for experimental animals that experience extreme cooling, their lifespan is extended, but their immune and reproductive systems exhibit abnormalities.

In addition, there are many factors that may affect the length of human lifespan. For example, our dietary habits, genetic factors, environmental factors, and so on. Body temperature may only be one of the factors affecting lifespan.

In addition, we also need to consider the range of 'normal' body temperature. According to the National Library of Medicine in the United States, the normal temperature range for a healthy adult is between 98.6 degrees Fahrenheit and 100.4 degrees Fahrenheit. In addition, the temperature within the normal physiological range is "normal", and if the temperature is too low or too high, it may indicate a health problem. Therefore, if body temperature is strictly restricted within a normal range, it may not be possible to see any correlation related to prolonged lifespan.

In addition, there are other studies suggesting that people with lower than normal body temperature are more susceptible to infection, coma, or death. For example, according to the British Medical Journal, an 87 year old woman was admitted to the hospital after suffering from pneumonia, with a temperature of only 93.2 degrees Fahrenheit. However, according to another study, temperatures above the normal range also increase the risk of cardiovascular disease and stroke.

Finally, it is worth noting that the relationship between body temperature and lifespan may also vary depending on individual differences. Some people's lifespan is indeed benefited by hypothermia, while others' lifespan is not affected or may even be negatively affected. This is also why scientists must conduct in-depth research. From this perspective, we need more scientific research to fully understand the relationship between human body temperature and lifespan.

However, due to experimental limitations, the above research is difficult to test in humans. However, some data suggests that lower body temperatures may be associated with longer lifespan. For example, according to the JAMA Network Open magazine, by analyzing over 180000 blood samples, researchers found that lower body temperature is associated with longer lifespan, especially for women. Specifically, when a woman's body temperature falls below the normal range (i.e. 97 to 98.6 degrees Fahrenheit), their lifespan is extended by an average of 0.3 years.

In addition, there is other evidence suggesting a possible relationship between body temperature and lifespan. For example, research has shown that cold environments may be beneficial for some people. In a study published in the Journal of the American Heart Association, researchers investigated the cardiovascular health of nearly 1000 Finnish men, and found that the incidence rate of cardiovascular events was much lower for men working in cold environments, which indicates that lower ambient temperature may have the benefits of protecting cardiovascular health.

In addition, some experimental results suggest that the relationship between body temperature and lifespan may be influenced by specific genes. For example, a gene called "FOXO3" has been shown to be associated with longevity. In a study published in the journal Cell Metabolism, researchers used experimental animal models and found that activating the FOXO3 gene can lower body temperature and prolong lifespan. However, the relationship between this gene and individual body temperature and lifespan may vary depending on individual differences.

There are also some other factors worth our attention on this topic. For example, research has shown that some foods, such as chili peppers and ginger, may increase body temperature, thereby helping to burn more calories, increase metabolism, and lose weight. And weight control has also been proven to promote longevity. In addition, some people regulate their body temperature by taking ice baths, exercising in cold environments, and other methods to enhance their immune system and help improve lifespan.

Although there are some studies supporting the relationship between body temperature and lifespan, we still need to keep in mind that we need more research to gain a comprehensive understanding of this issue. We need to conduct more extensive research to determine whether body temperature is truly the main factor affecting lifespan, or whether other factors exist. We also need to note that different people may have differences, and the impact of body temperature on their lifespan may also be different.

In this article, we explore the relationship between body temperature and lifespan. We point out that although there are some scientific studies supporting the possibility that people with body temperatures below the normal range may have a longer lifespan, this relationship is not absolute and may vary depending on physical differences. We also discussed other factors that affect lifespan, such as dietary habits, genetic factors, environmental factors, and so on.

By adopting a healthy lifestyle, such as consuming sufficient nutrition, exercising more, and conducting regular physical examinations, we can help maintain good physical health and extend our lifespan. Finally, we also emphasize the need for broader research to better understand the relationship between body temperature and lifespan.
