The human body has a built-in mechanism to regulate its internal temperature, known as thermoregulation. Normal body temperature, which is a key indicator of our overall health, refers to the average temperature at which the body functions optimally. Although the average normal body temperature is considered to be about 37 degrees Celsius (98. 6 degrees Fahrenheit), it is important to keep in mind that each person’s body temperature can vary within a certain range.
To better understand the concept of normal body temperature, we can divide the topic into two main aspects: oral body temperature and core body temperature. Oral body temperature is the temperature measured in the mouth with a thermometer, while core body temperature represents the temperature inside the body, near vital organs such as the heart and brain.
Interesting fact: Body temperature can fluctuate throughout the day, reaching its maximum in the late afternoon and its minimum in the early morning. Additionally, factors such as physical activity, hormonal changes, and the environment can also influence body temperature.
Body temperature is usually measured with a thermometer in one of the most common areas, such as the mouth, armpit, rectum or ear. Oral temperature is the most used method in adults, while rectal temperature is usually used in babies and young children. Let’s look in more detail at the average normal body temperature by age:
| Age group | Average normal body temperature |
|---|---|
| Newly born | 97. 7-99. 5°F (36. 5-37. 5°C) |
| Infants and children | 97. 9-99. 7°F (36. 6-37. 6°C) |
| Adults | 97. 8-99°F (36. 5-37. 2°C) |
It should be noted that a body temperature that is slightly above or below average does not necessarily indicate an underlying health problem. However, consistently high or low temperatures may warrant further medical attention as they could be signs of an infection or other medical condition. Monitoring body temperature is important as it helps healthcare professionals assess a person’s health status and make appropriate therapeutic decisions.

Understanding Body Temperature: What You Need to Know
Normal body temperature:
- Normally, the normal average body temperature of adults ranges between 36. 1°C (97°F) and 37. 2°C (99°F).
- However, it is important to note that normal body temperature can vary throughout the day, with it typically being lowest in the early morning and highest in the late afternoon or evening.
- Factors such as age, activity level, hormonal changes, and the external environment can also influence body temperature.
“Normal body temperature is a range rather than a specific value, and slight deviations from this range do not necessarily indicate disease.”
Abnormal body temperature:
- Fever: Fever is a temporary increase in body temperature, usually in response to an infection or illness. It is characterized by a higher than normal body temperature.
- Hypothermia: Hypothermia occurs when body temperature drops below normal values. It may be due to prolonged exposure to low temperatures or underlying diseases.
| Abnormal body temperature type | Temperature range | Possible causes |
|---|---|---|
| Fever | Above 37. 2°C (99°F) | Infection, inflammation, certain medications |
| Hypothermia | Below 36. 1°C (97°F) | Cold exposure, certain medical conditions |
It is essential to monitor and understand body temperature fluctuations as they can provide valuable information about a person’s health status. If you are concerned about your body temperature or experience persistent abnormal readings, it is recommended that you consult a healthcare professional for appropriate evaluation and guidance.
The Basics: What is Body Temperature?
Human body temperature is usually measured in degrees Fahrenheit (°F) or degrees Celsius (°C). The normal body temperature range varies slightly depending on the measurement method and the age of the individual. In adults, the normal average body temperature ranges between 36. 1°C (97°F) and 37. 2°C (99°F). However, it is essential to remember that body temperature can fluctuate throughout the day and can be influenced by factors such as physical activity, stress and hormonal changes.
Important information:
- Body temperature is a key indicator of a person’s health status.
- Normal body temperature ranges between 36. 1°C (97°F) and 37. 2°C (99°F) for adults.
- Body temperature can vary throughout the day and is affected by external factors.
The human body maintains its internal temperature through a process called thermoregulation, which involves the coordination of several physiological mechanisms. The hypothalamus, a part of the brain, acts as the body’s internal thermostat, receiving signals from temperature receptors located throughout the body and adjusting the body’s responses accordingly. When body temperature deviates from the normal range, various physiological responses occur to restore balance and maintain optimal functioning.
| Age group | Normal body temperature (°F) | Normal body temperature (°C) |
|---|---|---|
| Infants (0-2 years) | 97. 9°F – 100. 4°F | 36. 6°C – 38. 0°C |
| Children (3-10 years) | 97. 8°F – 99. 0°F | 36. 6°C – 37. 2°C |
| Adolescents and adults | 97. 0°F – 99. 0°F | 36. 1°C – 37. 2°C |
Normal Body Temperature: Myth or Fact?
Definition of normal body temperature
The traditional notion that the normal body temperature is 37°C (98. 6°F) dates back to the 19th century and was established by German physician Carl Wunderlich. However, more modern studies indicate that the normal average body temperature may be slightly lower.
Recent research published in the journal JAMA Network Open suggests that the normal average body temperature for adults is currently close to 36. 4°C (97. 5°F). This study, which analyzed data from more than 35, 000 participants, revealed that average body temperature has gradually decreased over the last century. Furthermore, the study also revealed that there is significant individual variation in body temperature, with some individuals naturally having temperatures slightly above or below average.
Despite these results, it is important to keep in mind that body temperature can fluctuate throughout the day. Factors such as physical activity, stress, and even food and drink consumption can temporarily influence body temperature readings. This reinforces the notion that there is no definitive “normal” body temperature applicable to everyone at all times.
Table: Factors that influence body temperature
| Factors | Effect on body temperature |
|---|---|
| Physical activity | Raises body temperature |
| Stress | Raises body temperature |
| Food and drink consumption | May temporarily lower or raise body temperature |
To accurately assess a person’s body temperature, it is recommended to take multiple readings at different times of the day and track any deviations from your personal baseline value. This can help identify fever or hypothermia, which are signs of abnormal body temperature.
- Recent studies indicate that the normal average body temperature of adults may be closer to 36. 4 ° C (97. 5 ° F).
- Body temperature can fluctuate throughout the day and influence factors such as physical activity and stress.
- To precisely evaluate a person’s body temperature, it is necessary to make several readings at different times of the day.
Understanding body temperature complexities is crucial for medical professionals to identify possible health problems and provide adequate care to their patients.
Factors that affect body temperature
1. Environmental conditions: The environment plays an important role in the regulation of body temperature. Extreme temperatures, such as extreme heat or cold exposure, can make the body adjust its temperature accordingly. For example, when it is hot, the body sweats to try to cool, while when it is cold, it trembles to generate heat.
2. 2. Physical activity: physical activity and exercise can cause a temporary increase in body temperature. When performing physical effort, muscles generate heat, which causes an increase in body temperature. This increase is usually temporary and normally returns to normal after a rest period.
Important Note
It is essential to keep in mind that body temperature can fluctuate throughout the day. The lowest body temperature is usually experienced early in the morning, while the highest occurs late in the afternoon or early night.
3. Disease or infection: When the body is fighting a disease or infection, it can trigger an increase in body temperature. This increase, known as fever, is the body’s natural defense mechanism to combat pathogens. Fever is usually accompanied by other symptoms, such as chills, sweating and fatigue.
- Hormonal imbalances: Certain hormonal imbalances, such as a hyperactive thyroid gland (hyperthyroidism) or hearing impaired (hypothyroidism), can affect the regulation of body temperature. These conditions can make a person’s body temperature constantly or lower than normal.
- Medications: Some medications can affect body temperature as a side effect. For example, certain antidepressants and antipsychotics can interfere with body thermoregulation, causing temperature fluctuations.
- Age: body temperature may vary depending on age. Babies and young children usually have an average body temperature slightly higher than that of adults. In addition, older adults may experience a decrease in body temperature regulation, which makes them more susceptible to extreme temperatures.
Taking these factors into account, health professionals can better interpret body temperature changes and perform appropriate medical interventions when necessary.
Measuring Body Temperature: Different Methods
One of the most used methods to measure body temperature is oral temperature measurement. It consists of placing a thermometer under the tongue and waiting for a few minutes to obtain a precise reading. It is a no n-invasive and relatively fast method, so it is comfortable for routine temperature controls. However, it may not be suitable for people who cannot keep the thermometer in their mouths constantly or for those who have respiratory problems.
- Oral temperature measurement is not invasive and is comfortable for routine controls.
- It may not be adequate for people who cannot keep the thermometer in their mouths constantly.
- People with respiratory problems can find oral measurement difficult.
- The rectal temperature measurement is considered the most accurate method to obtain central body temperature.
- It is usually used in infants and young children.
- Rectal measurement is an invasive technique that may not be comfortable for people.
| Method | Advantages | Disadvantages |
|---|---|---|
| Oral measurement | No n-invasive and comfortable | It may not be suitable for certain people |
| Rectal measurement | Considered the most accurate | Invasive and uncomfortable |
It is important to keep in mind that the different methods of body temperature measurement can yield slightly different results. Therefore, it is essential to follow the manufacturer’s instructions and take into account personal circumstances to obtain the most precise readings. It is recommended to consult a healthcare professional in the case of people with specific problems or conditions that may affect temperature measurement.
Body Temperature Variations: Age and Gender Differences
Aging and body temperature: As people age, their mechanisms for regulating body temperature can undergo changes, which causes variations in normal body temperature. Although there is a certain debate in the scientific community, studies suggest that older people tend to have a medium body temperature slightly lower than that of younger adults. Factors such as the decrease in the metabolic rate, changes in blood flow and decline in the thermoregulating function can contribute to this phenomenon. It is important to note that individual variations and health conditions can influence body temperature regardless of age.
“Researchers have discovered that older people can have an average body temperature of around 36. 1 ° C (97 ° F) at 36. 4 ° C (97. 5 ° F), which is slightly lower than the average commonlyaccepted 37 ° C (98. 6 ° F) for adults. “
Sex and body temperature: Another factor that can affect the variations in body temperature is sex. Although the differences are not substantial, investigations indicate that women tend to have an average body temperature slightly higher than that of men. Hormonal fluctuations in women, especially during the menstrual cycle, can contribute to these variations. However, it is important to take into account individual differences and health conditions when evaluating body temperature, since variations between sam e-sex individuals can be significant.
“Studies have shown that the average body temperature of women is approximately 0. 4 ° F (0. 2 ° C) higher than that of men, with an average ranging between 98. 9 ° F (37, 2° C) and 99. 4 ° F (37. 4 ° C) for women compared to 98. 5 ° F (36. 9 ° C) and 99. 1 ° F (37. 3 ° C) for men”
Knowing age and sex differences in body temperature can help health professionals to perform evaluations and make therapeutic decisions with greater knowledge of cause. In addition, it highlights the importance of taking into account individual variations and health conditions when interpreting body temperature readings. It is necessary to continue investigating in this field to fully understand the complex interaction between age, sex and body temperature.
Abnormal Body Temperature: When to Seek Medical Help
When body temperature rises above normal values, a condition known as fever or pyrexia occurs. Fever is usually a sign that the body is fighting an infection or fighting inflammation. Although mild fevers can be managed at home, it is important to know when medical attention is necessary. As a general rule, adults should consider seeking medical help if their body temperature reaches or exceeds 102°F (38. 9°C) and persists for more than a few days. Additionally, people with underlying health conditions, weakened immune systems, or symptoms such as severe headache, chest pain, shortness of breath, or confusion should consult a healthcare professional immediately.
- Seek medical help if body temperature reaches or exceeds 38. 9°C (102°F) and persists for more than a few days.
- People with underlying health problems, weakened immune systems, or severe symptoms such as severe headache, chest pain, shortness of breath, or confusion should consult a healthcare professional immediately.
- Elevated body temperature in infants younger than 3 months should be considered a medical emergency and medical help should be sought without delay.
Note: Although body temperature can also drop below normal values, it is usually not a cause for immediate concern unless accompanied by other serious symptoms. Hypothermia, or abnormally low body temperature, is a medical emergency that requires immediate medical attention.
It is important to remember that abnormal body temperature can vary depending on age, underlying health conditions, and individual factors. It is always recommended to consult a healthcare professional to accurately assess the situation and determine the appropriate course of action.
Body Temperature and Health: The Link

Maintaining Body Temperature: Tips for a Healthy Balance
- Keep properly hydrated: drinking enough water throughout the day is crucial to regulate body temperature. Dehydration can affect sweat production and reduce body’s ability to cool, which can cause overheating. Try to drink at least 8 glasses of water a day to guarantee adequate hydration.
- Wearing adequate clothing: dressing properly according to weather conditions can significantly influence body temperature regulation. When it is hot, choose baggy clothes and light colors, made with breathable tissues that allow the evaporation of sweat. With colder temperatures, clothing layers can help catch heat and isolate the body.
- Control your environment: creating a comfortable environment at home or at work is important to maintain a healthy body temperature. Use fans or air conditioning when you heat and adjust the thermostat to a comfortable level when it is cold. This helps optimize the natural capacity of the body to adapt to external temperature changes.
Remember: extreme temperature changes, such as sudden exposure to extremely cold or hot environments, can stress the body and alter their temperature regulation mechanisms. It is essential to gradually acclimatize to extreme conditions and dress accordingly.
In addition, incorporating regular exercise into your routine can also contribute to adequate thermoregulation. Physical activity helps improve cardiovascular function, increasing body capacity to regulate and maintain ideal body temperature.
