A crucial indicator of a person’s health is their body temperature. Fever, defined as a higher than normal body temperature, is usually a symptom of an underlying illness or infection. It is generally accepted that the normal average body temperature is about 37 degrees Celsius (98. 6 degrees Fahrenheit). However, it is important to keep in mind that each person’s body temperature can vary slightly and what may be considered a fever for one person may not be a fever for another.
With a standard oral thermometer, a temperature of 36. 8 degrees Celsius (98. 2 degrees Fahrenheit) is not usually considered a fever. This temperature falls within what is considered normal for certain people. It is important to remember that normal body temperature can vary depending on several factors, such as age, activity level, and time of day. Additionally, other factors such as the menstrual cycle, recent physical activity, or even eating or drinking hot or cold substances can temporarily affect body temperature.

What is considered a normal body temperature?
Important information: Fever is generally defined as a temporary increase in body temperature, often accompanied by other symptoms such as body aches, cough or headache. Although 98. 2°F may be slightly higher than the average normal temperature, it is not considered a fever. However, it is important to note that normal body temperature can fluctuate throughout the day, influenced by factors such as activity level, environmental conditions or the menstrual cycle in women.
The regulation of body temperature is controlled by the hypothalamus, a part of the brain responsible for maintaining the internal balance of the body or homeostasis. When the body detects an infection or disease, the hypothalamus raises body temperature to create an inhospitable environment for pathogens, which contributes to faster recovery.
The different methods of measuring body temperature
There are several methods to measure body temperature. The most used methods are
- Oral: It consists of placing a thermometer under the tongue, near the main blood vessels, and keeping it in place until you get a reading.
- Ear: The ear thermometer measures infrared heat waves emitted by the eardrum, providing a quick and reliable reading.
- Front: The infrared thermometers for the forehead measure the heat radiated by the temporal artery of the forehead, which allows to measure the contact without contact.
Each method has its advantages and limitations, and it is essential to follow the manufacturer’s instructions to obtain precise measurements. In addition, it is crucial to maintain adequate hygiene while using any of these methods to avoid the spread of infections.
| Method | Advantages | Limitations |
|---|---|---|
| Orally | Simple and comfortable | It can be influenced by the previous intake of food or drinks |
| Ear | Fast and no n-invasive | It can be affected by the accumulation of wax or an incorrect position |
| Forehead | Measurement without contact | External factors such as sweat or hair interference can affect precision |
Knowing the variations in body temperature and precise measurement methods helps both health professionals and people to make informed decisions about their health. It is important to recognize when a rise or decrease in body temperature can indicate an underlying health problem, and seek adequate medical care when necessary.
What is considered normal body temperature?
According to a study published in Jama Network Open, the average body temperature of adults is currently estimated at about 36. 4 ° C (97. 5 ° F). The researchers analyzed the data of almost 35, 000 adults and discovered that the average body temperature has gradually decreased in the last 160 years. This change could be attributed to various factors, such as improvements in health care, changes in the environment and differences in measurement methods over time.
Key point: It is estimated that the average body temperature of an adult is currently 36. 4 ° C (97. 5 ° F), below 37 ° C (98. 6 ° F) commonly accepted.
Although average body temperature may have changed, it is important to keep in mind that there are individual variations in body temperature. Some people may have a naturally higher or lower body temperature than average. In addition, body temperature can fluctuate throughout the day and can be influenced by factors such as physical activity, diseases and hormonal changes.
- Fever: a body temperature above normal values is usually considered fever. The specific temperature threshold for fever can vary depending on the individual and the situation. In general, fever is usually defined as a body temperature of 38 ° C (100. 4 ° F) or higher.
- Hypothermia: At the other end of the spectrum, a body temperature below the normal range is known as hypothermia. This condition occurs when the body loses heat more quickly than it can produce, and can endanger life if it is not treated promptly.
Body temperature control can provide valuable information about a person’s health status and help diagnose various conditions. To measure body temperature, oral, ear, front and rectal thermometers are usually used. If your body temperature worries or experiences symptoms of illness, it is recommended to consult a healthcare professional to evaluate and eastern it.
Recognizing Fever Symptoms
When recognizing the symptoms of fever, there are several key indicators to which attention must be paid:
- Increased body temperature: fever is normally defined as a body temperature above the normal range of 97. 7 to 99. 5 degrees F Ahrenheit (36. 5 to 37. 5 degrees Celsius).
- Touch heat sensation: the skin can feel warm or hot to touch, especially in areas such as forehead, neck and chest.
- Chills and chills: people with fever can experience episodes of chills and tremors, since the body tries to increase its internal temperature to combat the underlying cause.
In addition to these common symptoms, it is also important to be attentive to other possible signs related to fever, such as:
- Headache: Many people with fever experience headaches, who can go from slight to intense.
- Fatigue and weakness: fever can contribute to a general sensation of fatigue and weakness, making it difficult to carry out everyday activities.
- Sweating: Some individuals with fever may experience excessive sweating, since the body tries to cool.
It is important to keep in mind that fever is not a disease in itself, but rather a symptom of an underlying condition. Therefore, if you or someone who knows experiences fever symptoms, it is essential that you consult a medical professional to obtain an appropriate diagnosis and treatment plan.
Important: If fever is accompanied by serious symptoms such as breathing difficulty, chest pain, confusion or persistent vomiting, immediate medical attention should be sought, since it could be a sign of a severe medical emergency.
The Significance of Accurate Temperature Measurement in Medicine
A method usually used to measure body temperature is oral thermometry. It consists of placing a thermometer under the tongue and keeping it there for a certain time. It is important to keep in mind that the accuracy of this method can be influenced by factors such as the recent intake of food or drinks, smoking or breathing through the mouth. In addition, oral thermometers may not be suitable for young children or people with difficulties in keeping their mouths closed during measurement.
The precision is key: the precise measurement of the temperature is crucial for a diagnosis and adequate treatment decisions. Even a small deviation in temperature reading can lead to an incorrect evaluation of the patient’s condition.
Another widely used method is the measurement of body temperature by means of a digital thermometer placed in the rectum. This technique, known as rectal thermometry, provides more precise results than oral thermometry. However, it is mainly used in infants and young children due to their invasive character and the possible discomforts it can cause to the elderly. Be careful when performing rectal thermometry to avoid injuries and guarantee the patient’s comfort.
- The role of infrared thermometers: in recent years, infrared thermometers without contact have gained popularity in the medical field. These devices use infrared technology to measure temperature without direct contact with the patient’s skin, which makes them suitable for fast and hygienic readings. However, it is essential to take into account the distance and angle of placement of the thermometer, since inappropriate use can lead to inaccurate measurements.
| Method | Precision | Suitable for | Considerations |
|---|---|---|---|
| Oral thermometry | Moderate | Older adults and children | Factors that influence precision (food intake, smoking, oral respiration) |
| Rectal thermometry | high | Little infants and children | It requires adequate technique, invasion and possible discomfort |
| Infrared thermometry | Variable | All ages | Distance and Angle Considerations for Accurate Readings |
Is 98.2°F considered a fever?
Body temperature is an important vital sign that helps healthcare professionals assess a person’s overall health. Although 98. 6°F is widely accepted as the average body temperature, it is important to note that normal body temperature can range between 97°F (36. 1°C) and 99°F (37. 2°C) inhealthy adults. Additionally, factors such as activity level, time of day, and age can influence variations in body temperature.
Important: A person’s body temperature is regulated by the hypothalamus, which acts as the body’s internal thermostat. Fever is usually defined as a temporary increase in body temperature, often due to an underlying illness or infection.
In the medical field, fever is usually defined as a higher than normal body temperature. Although a temperature of 98. 2°F may be slightly below average, it is still within normal ranges and is not necessarily considered a fever. However, it is essential to take other symptoms and individual circumstances into account when determining whether or not a person’s temperature indicates the presence of fever.
- Factors to consider when evaluating body temperature:
- Presence of other symptoms such as sweating, chills or body aches.
- Age and general health status of the individual.
- Recent exposure to extreme temperatures or physical exertion.
- Medical history and any known underlying illnesses.
- Any recent travel or potential exposure to infectious diseases.
It is always recommended to consult a healthcare professional or seek medical advice if you are concerned about your body temperature or experiencing other symptoms. Remember that an accurate diagnosis and proper medical evaluation are essential to determine the cause and proper treatment of any potential illness or condition.
| Normal temperature | Classification |
|---|---|
| Below 36. 1°C (97°F) | Hypothermia |
| 97°F – 99°F (36. 1°C – 37. 2°C) | Normal |
| 99. 1°F – 100. 3°F (37. 3°C – 38. 5°C) | Low fever |
| Above 100. 4°F (38°C) | Fever |
Factors That Can Impact Body Temperature
One of the most important internal factors that influence body temperature is metabolism. Metabolism refers to the chemical processes that take place within cells to maintain life. A person’s metabolic rate can influence their body temperature, as a higher metabolic rate usually translates into greater heat production. This means that people with a faster metabolism may have a slightly higher average body temperature than those with a slower metabolism.
Hormones and Body Temperature
“Hormones play a fundamental role in the regulation of body temperature.”
The hormones, which are messengers of the organism, also play a fundamental role in the regulation of body temperature. These chemicals are produced by various glands of the body and can affect the hypothalamus, the part of the brain responsible for maintaining body temperature. Hormonal imbalances, such as those experienced during menopause or thyroid disorders, can cause body temperature fluctuations. For example, women who experience suffocals during menopause can suffer temporary increases in body temperature.
- Body metabolism and heat production
- Hormonal imbalances
- Physical activity and exercise
- Stress and emotional responses
- Medications and substances
- Genetics and individual variations
- Age
- Diseases and infections
- Sleep patterns and circadian rhythms
- Environmental factors
Physical activity and exercise can also influence body temperature. During the exercise, the body produces more heat as the muscles work more, which causes an increase in body temperature. In addition, emotional responses and stress can trigger changes in body temperature. Stress can cause an increase in stress hormones production, which in turn can raise body temperature.
It is important to note that, although these factors can influence body temperature, the normal body temperature interval may vary from one person to another. Factors such as genetics, age, sleep patterns and even the time of day can contribute to individual body temperature variations. In addition, certain diseases and infections can cause a temporary increase or decrease in body temperature. Therefore, it is essential to take these factors into account to precisely interpret body temperature measurements and determine if 98. 2 ° F is an indicative of fever or is within the normal range for an individual.
When to seek medical attention for a temperature of 98.2°F
1. 1. Infants and young children: In general, infants and young children are more vulnerable to diseases and infections. Therefore, if an infant or a small child has a temperature of 98. 2 ° F and presents other worrying symptoms such as irritability, difficulty breathing or rejection of eating, it is important to look for medical attention quickly. This is especially true in the case of infants under 3 months, since they have not yet fully developed their immune system and run a greater risk of contracting serious infections.
2. Immunodepressed individuals: people with a weakened immune system, such as those who undergo cancer treatments or suffer from certain chronic diseases, may be more susceptible to infections. If an immunosuppressed individual has a temperature of 98. 2 ° F and experiences symptoms such as persistent fatigue, body pain or a general sense of discomfort, it is advisable to consult a healthcare professional. This is because even a slight deviation from its usual temperature range may indicate an underlying infection or an exacerbation of its state.
| Situation | Signs or symptoms |
|---|---|
| Little infants and children | Irritability, difficulty breathing, negative to eat |
| Immunosuppressed people | Persistent fatigue, body pain, general sensation of discomfort |
Home Remedies to Manage Fever Symptoms
1. Stay Hydrated
Drinking a lot of liquid is essential when you have a fever. Fever can cause dehydration, so it is important to replenish lost liquids to avoid major complications. Water, infusions and clear broths are good options to stay hydrated. Avoid coffee and alcohol beverages, as they can contribute to dehydration.
2. Get Plenty of Rest
Resting is essential for the body to fight the infection that causes fever. Be sure to sleep enough and avoid strenuous activities during fever. In this way, your immune system can focus on recovering instead of overloading. Take breaks throughout the day to rest and keep energy.
3. Use Cold Compresses
Applying cold compresses on the forehead, neck and wrists can help reduce fever symptoms. This method acts cooling these points of pulse, which in turn helps lower body temperature. Moisten a clean cloth with cold water, drain the excess and apply it on the areas mentioned for several minutes in a row. Avoid using very cold ice or water directly on the skin, as it can cause discomfort.
Remember that it is important to control the fever and go to a professional doctor if necessary. Home remedies can temporarily relieve symptoms, but do not address the underlying cause of fever. If the fever persists for more than a few days or is accompanied by serious symptoms, such as difficulty breathing or confusion, it is essential to consult a healthcare professional to obtain adequate diagnosis and treatment.
