7 Fascinating Facts About Body Temperature

The body temperature is a fascinating thing and it plays a huge role in how we function. Starting from the way we regulate our metabolism to the way we respond to external temperatures, it impacts all. But did you know that your temperature has more secrets than you may think? Yes, it does! In this article, we’ll explore seven fascinating facts about body temperature that you probably didn’t know before. Let’s get started.

Age, Sex, and time of day Affects your Body Temperature

Most people think of 98.6 degrees Fahrenheit as the normal human body temperature. But this number is actually just an average of what normal body temperatures are. The reality is that your body temperature can fluctuate throughout the day, and it’s different for everyone.

Your body temperature fluctuates throughout the day in response to many different things, such as age, sex, and time of day. Aging affects our body's ability to regulate temperature, with older people typically generating less heat than younger individuals. In addition, men generally have higher baseline body temperatures than women due to a larger ratio of muscle to fat. Lastly, time of day is an important factor when it comes to body temperature; most people experience their highest temperature in the late afternoon and lowest during the early morning. These results demonstrate that our internal thermometers adapt depending on external circumstances.

Your Body Temperature Changes During Exercise

Our body temperature increases as we exercise, acting like a natural cooling mechanism. As we move around and our muscles produce energy, the resulting heat generates a higher body temperature. Most of us don’t notice it until it reaches 37.5°C or 99.5°F, which can cause fatigue and dehydration if left unchecked. To keep our core temperature in check, our bodies move blood to the vessels near our skin and open sweat glands to cool off--which is why most of us perspire when exercising. So next time you break a sweat during your workout, know that it’s your biology doing its job!

Body Temperature Changes During Sleep

The body operates at an optimal temperature for its everyday activities, but it changes while we sleep. To save energy, our bodies lower their temperature slightly when we hit the hay, and this drop is especially clear during the first few hours. During REM sleep, a period of deep sleep where most dreaming occurs, the body can actually become a bit warmer than its resting state due to increased metabolic activity. Temperature control is an important part of sleeping well at night; blankets to keep us warm or air conditioning to stay cool can help us adjust our climate for better slumber. While everyone has their own ideal chamber temperature for sleeping, maintaining a room at around 65 degrees Fahrenheit is generally accepted as a good guideline for comfortable rest.

Environmental Conditions can Affect body Temperature

The human body adjusts its temperature to the environment, and environmental conditions like heat and cold can have a major effect. In extremely hot temperatures, our body's natural cooling system kicks in and works hard to maintain a healthy internal temperature - however, if it is particularly hot or humid, this process can be hindered and our body temperature can rise faster than usual. Similarly, being exposed to cold temperatures forces our body to work hard in order to produce extra warmth so we don't become too cold; when these efforts fail due to prolonged exposure, our body temperature drops below normal. It is important for us to take caution and pay close attention to changes in environmental weather in order to ensure we avoid any serious health issues such as heat stroke or hypothermia.

Body Temperature and COVID-19

It is well known that humans have an average body temperature of 98.6 degrees Fahrenheit or 37 Celsius. Knowing this, it can be a helpful indicator as to whether or not one might have contracted COVID-19, especially since fever and chills are two early symptoms that may present in those infected. If your normal body temperature rises above the average temperature reading, consider seeking medical advice as it could be indicative that you may have the virus. However, it should also be taken into account that other possible conditions such as the common cold and flu can cause elevated temperatures. It is always important to be aware of symptoms regardless of your body’s temperature so you continue to remain safe and healthy.

Each body cell has its own Temperature

It may come as a surprise to some, but each cell in the human body has its own regulated temperature. This is largely due to the relatively high metabolic rate and energy consumption within the cell, which creates localized heat build-up. While it may be difficult for us to sense this heating on a cellular level - let alone regulate it - it does have implications for our overall health, particularly that of our internal organs. For example, after being exposed to extreme temperatures or food poisoning toxins, cells can become damaged thereby disrupting a number of physiological processes. The temperature of individual cells therefore plays an important role in our overall health and wellbeing.

The body Temperature of a new-born baby is About 97 Degrees Fahrenheit

A newborn baby’s body temperature can be an important indicator of their overall health and wellbeing after birth. On average, normal body temperature for a newborn is 97 degrees Fahrenheit, although it’s worth noting that the range can vary slightly depending on the individual. A lower-than-normal body temperature may be a sign of hypothermia and in such cases, immediate attention should be sought from a medical professional. Conversely, if your newborn's temperature is higher than normal then it could be an indication of infection or illness. If in doubt, always consult your paediatrician to ensure your little one’s health is being taken care of properly.


From the effects of exercise on body temperature to how it varies by gender, we've covered some fascinating facts about human body temperature. It's amazing to think that something as simple as a few degrees can have such an impact on our health and wellbeing. Knowledge is power, so educate yourself on the subject and always keep your own individual needs in mind when monitoring your body temperature.
