Our bodies are complex systems that are constantly working to maintain a healthy balance. One of the most important factors in this balance is body temperature. When our body temperature is too high or too low, it can cause a variety of health problems.
In this article, we will discuss what normal body temperature is, how it is regulated, and what can happen when our body temperature is not normal.
So, what exactly is normal body temperature?
What is Normal Body Temperature?
Here are 8 important points about normal body temperature:
- Average: 98.6°F (37°C)
- Range: 97°F-99°F (36.1°C-37.2°C)
- Varies by person
- Higher in children
- Lower in elderly
- Affected by time of day
- Affected by activity level
- Important for overall health
These are just a few of the important things to know about normal body temperature. By understanding what is normal for you, you can be more aware of any changes that may indicate a health problem.
Average: 98.6°F (37°C)
The average normal body temperature is often stated as 98.6°F (37°C). However, it is important to note that this is just an average. Normal body temperature can vary from person to person and can also fluctuate throughout the day.
- Variation among individuals:
Some people naturally have a higher or lower body temperature than others. This is perfectly normal and does not necessarily indicate a health problem.
- Age:
Children tend to have higher body temperatures than adults. This is because their bodies are still developing and their metabolism is faster.
- Time of day:
Body temperature is typically lowest in the early morning and highest in the late afternoon or early evening. This is because our body temperature follows a circadian rhythm, which is our body's natural sleep-wake cycle.
- Activity level:
Exercise and other physical activity can raise body temperature. This is because our muscles generate heat when they work.
It is important to be aware of your own normal body temperature so that you can recognize any changes that may indicate a health problem. For example, a fever is defined as a body temperature of 100.4°F (38°C) or higher. Fevers can be caused by a variety of infections and illnesses.
Range: 97°F-99°F (36.1°C-37.2°C)
While the average normal body temperature is 98.6°F (37°C), it is important to remember that this is just an average. Normal body temperature can vary from person to person and can also fluctuate throughout the day. For most people, a normal body temperature will fall within the range of 97°F to 99°F (36.1°C to 37.2°C).
There are a number of factors that can affect a person's body temperature, including:
- Age: Children tend to have higher body temperatures than adults. This is because their bodies are still developing and their metabolism is faster.
- Time of day: Body temperature is typically lowest in the early morning and highest in the late afternoon or early evening. This is because our body temperature follows a circadian rhythm, which is our body's natural sleep-wake cycle.

Varies by person
Normal body temperature can vary from person to person. This is because there are a number of factors that can affect a person's body temperature, including:
- Age: Children tend to have higher body temperatures than adults. This is because their bodies are still developing and their metabolism is faster.
- Sex: Women typically have slightly higher body temperatures than men. This is due to hormonal changes during the menstrual cycle.
- Muscle mass: People with more muscle mass tend to have higher body temperatures than people with less muscle mass. This is because muscle tissue generates heat.
- Body fat percentage: People with a higher body fat percentage tend to have lower body temperatures than people with a lower body fat percentage. This is because fat tissue insulates the body and prevents heat from escaping.
- Health status: People with certain health conditions, such as thyroid problems or infections, may have abnormal body temperatures.
- Medications: Some medications can affect body temperature. For example, fever-reducing medications can lower body temperature, while some antibiotics can raise it.
It is important to be aware of your own normal body temperature so that you can recognize any changes that may indicate a health problem. For example, a fever is defined as a body temperature of 100.4°F (38°C) or higher. Fevers can be caused by a variety of infections and illnesses.
If you are concerned about your body temperature, talk to your doctor. They can help you determine if your temperature is normal and, if not, what may be causing the problem.
Even though normal body temperature can vary from person to person, it is important to maintain a healthy body temperature. This is because our bodies need to be able to regulate their temperature in order to function properly. When our body temperature is too high or too low, it can lead to a number of health problems.
Higher in children
Children tend to have higher body temperatures than adults. This is because their bodies are still developing and their metabolism is faster. Children's bodies also produce more heat than adults' bodies because they have a higher surface area to volume ratio. This means that they lose heat more easily, so their bodies need to work harder to maintain a healthy temperature.
The average normal body temperature for children is between 99°F and 100°F (37.2°C and 37.8°C). However, it is important to note that this is just an average. Some children may have normal body temperatures that are slightly higher or lower than this range.
There are a number of factors that can affect a child's body temperature, including:
- Age: Newborns and infants tend to have higher body temperatures than older children. This is because their bodies are still developing and their immune systems are not yet fully mature.
- Activity level: Exercise and other physical activity can raise a child's body temperature. This is because their muscles generate heat when they work.
- Environment: Hot weather can cause a child's body temperature to rise, while cold weather can cause it to fall.
- Clothing: Wearing too much clothing can trap heat and cause a child's body temperature to rise.
- Medications: Some medications can affect a child's body temperature. For example, fever-reducing medications can lower body temperature, while some antibiotics can raise it.
It is important to be aware of your child's normal body temperature so that you can recognize any changes that may indicate a health problem. For example, a fever is defined as a body temperature of 100.4°F (38°C) or higher. Fevers can be caused by a variety of infections and illnesses.
If you are concerned about your child's body temperature, talk to their doctor. They can help you determine if your child's temperature is normal and, if not, what may be causing the problem.
Lower in elderly
As people age, their body temperature tends to decrease. This is because a number of factors, including:
- Decreased metabolism: As people age, their metabolism slows down. This means that their bodies produce less heat.
- Loss of muscle mass: As people age, they tend to lose muscle mass. Muscle tissue generates heat, so a decrease in muscle mass can lead to a decrease in body temperature.
- Changes in body composition: As people age, they tend to lose weight and gain body fat. Body fat insulates the body and prevents heat from escaping, so an increase in body fat can lead to a decrease in body temperature.
- Changes in the endocrine system: The endocrine system helps to regulate body temperature. As people age, their endocrine system may not work as well as it used to, which can lead to changes in body temperature.
- Medications: Some medications that are commonly taken by older adults can affect body temperature. For example, beta-blockers and ACE inhibitors can both lower body temperature.
The average normal body temperature for older adults is between 96°F and 98°F (35.6°C and 36.7°C). However, it is important to note that this is just an average. Some older adults may have normal body temperatures that are slightly higher or lower than this range.
It is important to be aware of your own normal body temperature so that you can recognize any changes that may indicate a health problem. For example, a body temperature of 95°F (35°C) or lower is considered to be hypothermia. Hypothermia can be dangerous, especially for older adults. If you think someone may be experiencing hypothermia, call 911 immediately.
If you are concerned about your body temperature, talk to your doctor. They can help you determine if your temperature is normal and, if not, what may be causing the problem.
Affected by time of day
Our body temperature follows a circadian rhythm, which is our body's natural sleep-wake cycle. This means that our body temperature varies throughout the day.
- Lowest in the early morning: Our body temperature is typically lowest in the early morning, between 2:00 AM and 4:00 AM. This is because our metabolism slows down during sleep.
- Highest in the late afternoon or early evening: Our body temperature is typically highest in the late afternoon or early evening, between 4:00 PM and 6:00 PM. This is because our metabolism is most active during this time of day.
- Gradually decreases throughout the night: Our body temperature gradually decreases throughout the night as we prepare for sleep. This is because our metabolism slows down as we get ready to rest.
- Slight increase in the morning: Our body temperature increases slightly in the morning as we wake up and prepare for the day. This is because our metabolism begins to speed up as we get out of bed and start moving around.
The normal range for body temperature throughout the day is between 97°F and 99°F (36.1°C and 37.2°C). However, it is important to note that this is just a general range. Some people may have normal body temperatures that are slightly higher or lower than this range.
Affected by activity level
Exercise and other physical activity can raise body temperature. This is because our muscles generate heat when they work. The amount of heat that is generated depends on the intensity and duration of the activity. Light to moderate exercise, such as walking or swimming, can raise body temperature by a few degrees Fahrenheit. Vigorous exercise, such as running or cycling, can raise body temperature by as much as 10 degrees Fahrenheit or more.
Body temperature typically starts to rise within a few minutes of starting exercise and continues to rise as the intensity and duration of the activity increases. After exercise, body temperature usually returns to normal within 30 minutes to an hour. However, it can take longer for body temperature to return to normal if the activity was particularly intense or prolonged.
It is important to stay hydrated when exercising, especially in hot weather. Drinking plenty of fluids helps to keep body temperature from rising too high.
If you are exercising and you feel dizzy, lightheaded, or nauseous, it is important to stop exercising and rest. These symptoms can be a sign of heat exhaustion or heat stroke, which are serious medical conditions that can occur when body temperature rises too high.
If you have any concerns about exercising and your body temperature, talk to your doctor. They can help you determine what activities are safe for you and how to stay safe while exercising.
