Temperature is an essential measurement to indicate overall health and wellness. Here's why you must start tracking your body temperature.
Body Temperature: Quick Facts
- A healthy person has a temperature between 97 and 99 degrees Fahrenheit.
- Body temperature is regulated by a gland in the brain (the hypothalamus).
- The hypothalamus triggers the body's thermal reactions to maintain homeostasis and to keep your body temperature near 99 degrees.
That said, there's no body like your body!
Personal health and other factors can affect your normal temperature range.
Here are some of the most common causes for temperature variations:
- Physical Activity
- Time Since Last Meal (digestion affects temperature!)
- Menstrual cycle
- Other Hormonal Changes
- Certain Medications
When you participate in intense physical activity, your body temperature rises (no surprises there). But do you know by how much? For example, it's common for marathoners to have a temperature of 102 degrees Fahrenheit at the finish line. That may not seem like a big deal, but it is.
This temperature increase is countered by perspiration (sweat) and the dilation of blood vessels, which stops your body from overheating, which can lead to dizziness, confusion, slurred speech, light-headedness, and even lead to some illnesses.
Outside of physical exercise, a dramatic increase in temperature can indicate a fever related to an illness.
What Causes a Fever?
A fever is an increase in body temperature, triggered by your immune system, which is intended to destroy bacteria or viruses.
Fever is therefore not a negative signal, but a signal that the immune system is intervening to fight an infection and protect the body. A fever means your immune system is working efficiently!
That said, it's important to measure a fever properly, and to understand what exactly this change in temperature indicates.
How to Track your Body Temperature
Knowing your temperature (and your temperature trends) is essential to help you better understand your general health. That's why it's important to measure it regularly—only by monitoring your temperature over time can you really understand the story its telling you about your body.
You could use a thermometer every morning and evening and manually record your temperature. But that's a lot of work.
That's why we developed a unique feature in the new Atria 2.0 smartwatch. Atria 2.0's infrared sensor tracks changes in your body temperature 24/7 and reports any abnormal activity, which could indicate warning signs of a change in your health. In many cases, tracking your temperature can help you predict illness ahead of time.
Body Temperature—The Overlooked Metric
Body temperature is an often-overlooked metric, but by now you can see why it's important—and why do you think you always get it checked when you visit a doctor? The unique body temperature sensor on the Atria 2.0 provides accurate readings and because it constantly records data, medical professionals can gain some helpful insights if you want to share your reports with them.
It can be good to know during your workouts.
Temperature Monitoring For Athletes
Tracking your temperature can give you insights when it comes to your training, nutrition during training, and your recovery.
The Atria 2.0 helps you understand your body's reaction to effort, better manage your thermoregulation, analyze in detail its changes during extreme exertions, and identify any metabolic concerns.
It can also help you track your effort and pace yourself more effectively.
By monitoring your body temperature during exercise, you can optimize your exertion while making sure you aren't heading into a dangerous overheating zone.
Temperature Monitoring for Pregnant Women
Overheating during pregnancy can be harmful to the baby.
Continuously analyzing your temperature makes it easy to track your health and ensure the baby is not being stressed in any way by body temperature.
It is another data point that you can share with your doctor to better monitor your health and physical stress levels during pregnancy!
Your Daily Temperature at a Glance
A prolonged or elevated temperature might indicate an allergy or a fever, which can be useful in the COVID-19 era.
Fevers is also useful to identify any side effects of medications or other medical conditions. A log of elevated temperature could be useful information for physicians, and with FitTrack Health you can easily share that information at your next visit.
Hypo or Hyperthyroidism
Your thyroid gland is like the controller for the body’s metabolism.
Irregular temperature trends are a strong indication of thyroid disorders. With hyperthyroidism (elevated metabolism) you might have a higher temperature than normal, and a lower one with hypothyroidism.
Having access to a regular log of body temperature could be very insightful if you are at risk of thyroid problems or other metabolic disorders.
While it’s normal to work up a sweat during exercise or strenuous activity, sometimes you can run too hot or get dehydrated, and develop heatstroke.
By having a baseline of temperatures from previous workouts, you can tell if you’re getting too hot and need to take a break to avoid heatstroke!
In cold weather, your body temperature may dip to dangerous levels, even if you’re working, layering, or staying active. In fact, the cold can sometimes confuse your body—though you may feel warm, your body temperature might be dangerously low. In fact, people who are suffering from hypothermia (which already causes confusion and disorientation) often feel as though they're "burning up" and remove their clothes. This is known as "paradoxical undressing."
You may not be aware of your core temperature, but having a reliable body temperature measurement can help alert you when it’s time to get out of the cold.
Atria 2.0 records your temperature 24/7 and reports the information to the FitTrack Health app. So you get a detailed picture of your temperature over time, hot or cold, all year round.
This is particularly useful for at-risk people or when the seasons change, especially in the fall and winter, when the risk of contracting a seasonal infection is even higher. Atria 2.0 makes it easy to monitor your body temperature so you know the best way to take care of your health.
