Interesting facts about body temperature

Body heat can reveal a lot about your health. Along with illness causing a high body temperature, your temperature changes as you age, when you smoke, and even when you tell a lie. Read on to find out more

1. Your body temperature goes up when you smoke

Here’s why: The temperature at the tip of a cigarette is 95 degrees Celsius. Inhale hot smoke, and it raises your lung temperature. When your lungs are hot, they are unable to cool or remove heat from your body.

As a result, it causes high body temperature. When you stop smoking, your body temperature returns to normal within about 20 minutes.

2. Your nose heats up when you lie

The anxiety brought on by a lie causes the nose and the areas around the eyes to get warm.

3. Cold may protect your brain from injuries

Doctors at Johns Hopkins Bayview Medical Centre in Baltimore developed a technique that purposefully causes low body temperature to prevent long-term disabling effects.

Known as therapeutic hypothermia, the treatment has been shown to prevent further injuries, especially in the brain, when performed within four hours of a heart attack.

4. Red pepper cause high body temperature

Red pepper may not only add some spice to your meals, but it can also cause high body temperature as part of the digestive process. Red pepper helps to reduce appetite and increase calorie expenditure, and when you burn more calories, you get high body temperature temporarily.

5. Keep your body temperature cool to sleep better

Your body temperature can affect how well you sleep. Scientists at the Netherlands Institute for Neuroscience in Amsterdam found that people slept better when their skin was slightly cooled.

The researchers fitted study participants with special suits that lowered their skin temperature by less than one degree centigrade. Although the suits didn’t affect the average body temperature, the participants didn’t wake up as often at night and went into a deeper sleep.

Cooling the skin’s surface temperature made the biggest difference among older participants who had complained of insomnia.

6. The older you get, the colder you become

If it seems like you’re always cold, even during hot season, it could be your age. Studies show that as we age, our average body temperature declines slightly. This is important to know, because seniors might actually be running a fever at lower temperatures than younger adults.

7. Body temperature can help tell time of death

This isn’t just crime-show fodder. When someone dies, their body begins to cool at a set rate: about -17 degrees Celsius (1.5 degrees Farenheit) an hour.

If an investigator examines the deceased within 24 hours, and the body hasn’t been in a room that’s not too hot or too cold, the low body temperature can be used to fairly accurately estimate the time of death.

8. That hat may not help you retain body heat

Remember your mum telling you to wear a hat when it’s cold outside because body heat is lost through your head? Turns out, her advice might not be completely spot-on.

When you lose body heat and you get low temperature, this drop happens from all parts of your body at an equal rate. How much body temperature you lose from your head depends on a number of factors, including how thick your hair is and how much energy you expend in the cold.

But because a child’s head is larger in proportion to the rest of the body’s surface, children can get a low body temperature from uncovered heads faster than adults.

9. Men and women are different when it comes to body temperature

When you’re exposed to cold, your body begins to conserve heat. It wants to protect your vital organs, such as your heart, lungs, and brain, so more blood flows to these areas and less to your hands and feet.

This happens to women much more quickly, meaning a woman’s hands and feet will get colder more quickly than a man’s. Women will feel the effects once the temperature goes below 21 degrees Celsius. For men, the chills won’t kick in until the temp dips below 19 degrees Celsius.

10. A fever can be your friend

Many people fret over a fever, but it actually can be helpful. A reaction of your body’s immune system, a fever indicates that you’re fighting off an infection, and it can help your body return to normal.

In most cases, the higher your body temperature, the harder your body is working to fight the infection. But if your fever doesn’t subside in a few days or if you have abnormally high body temperature get medical attention. —Internet sources
