What is normal body temperature range?

Our temperature affects all aspects of our health. It is often referred to as our inner clock that keeps us asleep and keeps us awake. Our temperature rises and fall is the fourth sign in our body to produce feelings of arousal or fatigue. When your body temperature drops, you will begin to feel tired. So, as your body temperature rises, you will feel stronger and more alert.

Remember that your temperature rises and falls throughout the day depending on your activities and environment. It is not surprising that when we place great physical needs in us the body temperature will rise. It happens that when you stop a physical activity your body temperature will drop.

What is Normal Body Temperature for an average human?

You may have heard that the “normal” body temperature is 98.6 ° F (37 ° C). This number is only medium. Your body temperature may rise or lower.

High or low temperature reading does not mean you are sick. There are many factors that can affect your body temperature, including your age, gender, time of day, and level of activity.

What is a healthy body temperature? Is it the same for all ages?

Your body’s ability to regulate temperature changes as you grow older.

In general, older people have more difficulty retaining heat. They are more likely to have low body temperature. Body temperature based on different ages given below-

Babies and children: In babies and children, the average body temperature ranges from 97.9°F (36.6°C) to 99°F (37.2°C).

Adults: In adults, average body temperature ranges from 97°F (36.1°C) to 99°F (37.2°C).

Adults above 65: In older adults, the average body temperature is lower than 98.6°F (37°C).

Always remember body temperature varies from person to person.

Many factors affecting your body temperature

Age

One of the most important factors that influence the normal temperature of the body is the cell. The effect of age on the temperature of the body is easy to observe in children and the elderly. 

Children tend to have a very high metabolic rate, meaning that the body converts food into energy very fast compared to adults.

At the other end of the spectrum, a century and a format of your choice. People over the age of 65 years old have a tendency to have a lower baseline temperature than that of their younger counterparts. And this decline in the performance-this study shows that people between the ages of 65-75 had a higher peak temperature than that of the people in the 75-85 em >85 age group. 

Besides having a lower baseline, older adults also have a more subdued immune response, which makes it very difficult to detect the infection.

Thus, continuous monitoring of the temperature is of crucial importance in nursing care. Because they have a lower basal temperature with the use of standard criteria to diagnose a fever, it will lead to an accident.

Sex

German physician Karl Marx put forward the idea of changing body temperature, depending on the gender. On average, women have a higher body temperature than their male counterparts. the women have a higher body fat percentage than men, female sex hormones, etc., etc.

A 1993 study found no significant differences in body temperature between the men’s and women’s. In fact, as of this review, which published in 2019, found that female subjects were, on average, tend to have a lower body temperature than men. But, as he points out, these are small differences.

Women’s body temperature is also influenced by hormones, and can rise or fall in different areas during the menstrual cycle.

But, keep in mind that a woman’s body temperature was higher during ovulation, and pregnancy and is also lower than at the start of the menstrual cycle.

Time of the Day

Researchers have found that our bodies often become warmer during the day. As a result, the early morning fever is likely to occur at a lower temperature than during the day.

The body undergoes significant fluctuations throughout the day. This is a “day shift”. As a rule, it is at the lowest level, in the early hours of morning, and it rises up after a person wakes up, reaching its peak in the late afternoon.

This change is consistent with the level of metabolic activity is at its lowest when we are sleeping, and increases as the day goes on.

The time of day is not the only thing that can affect the temperature. As the above grades show, young people tend to have higher body temperature. This is because our ability to regulate body temperature decreases with age.

Physical exertion

Your muscles need energy to work. During physical activity, muscles generate a tremendous amount of heat, which leads to an increase in the temperature of the body. The body tries to dissipate the excess heat and is for the recovery of the body to have a normal thermal state. But, sometimes, the body will not be able to cope with the rising temperatures and lose enough heat to maintain a stable core temperature.

The more you work the muscles necessary, and the more heat they produce. The degree of increase in body temperature during exercise relates to the intensity of the activity, as well as the amount of heat that is being lost by the body.

Works in hot and humid conditions, making it difficult for you to keep your body temperature within the normal range. This will open the door to the drying and / or heat, a disease that is very dangerous. That is why, experts have warned about the intense physical activity in hot or cold weather. 

The more your body gets to a certain level of physical activity, the better it is able to dissipate heat. Thus, the main focus must be patience and taking your time in the air from your body, and getting plenty of hydration for a more intense workout.

Continuous monitoring of the temperature may give you an idea of how your body’s coping with the intensity of the workout.

It makes use of a continuous monitoring of the temperature, to assess how the body changes as compared to the previous volume level. Application of continuous monitoring of the temperature, it can help you to customize your workouts to your body and level of fitness.

Stress

The temperature of the body rises in response to stress. Stress hormones such as cortisol and adrenaline cause a rise of body temperature. 

This increase in temperature is an adaptive response of the body to perceived threats. The liver is one of the world’s largest and most active organs in the body, and it has a significant effect on the temperature of the body.

Meals

Usually, there is a slight increase in body temperature for a short time after eating. If you are using the device for continuous monitoring of the temperature, you may notice a slight increase in temperature for 20 to 30 minutes after eating. 

This results in an increase in its metabolism and to improve digestion.

The level of physical activity and certain foods or beverages can also affect body temperature.

Drugs

Many drugs, including the different types of antibiotics (cephalosporins, penicillins, etc.) methyldopa, phenytoin, etc. are well-known to lead to an increase in the temperature of the body. Also, its widely-used chemical compounds, such as MDMA and cocaine, may also lead to an increase in the temperature of the body.

It is well known that cigarette smoking causes sharp jumps in the temperature of the body.

Medium of measurement

The body temperature readings will vary depending on the location of the measurement. In general, the axillary temperature is usually 0.3°C – – 0.6 °C 0.5°F (1°F) lower than oral temperature, and the passing of reading 0.3°C to 0.6°C 0.5°C -1°F) is greater than that of the oral readings.

Invasive procedures need to get accurate body temperature measurements. In lots of cases, there is no point in opting for invasive procedures, regardless of their level of accuracy and reliability. The erectile condition is a middle ground between accuracy and ease of use. But, in the last few years, rectal temperature measurement has fallen out of fashion because of the patient’s reluctance, and the spread of the infection.

Besides, how you take your temperature can affect reading. Armpit reading can be more complete than oral reading.

And readings from the mouth are usually lower than readings from the ear.

What is Fever body temperature?

Doctors consider a fever to be a body temperature that reaches or exceeds 100.4°F.

Symptoms of fever

  • chills
  • a headache
  • bitter taste
  • muscle aches
  • shivering
  • sweating
  • weakness

It is easy to assume that the fever is over 99 °, but temperatures are much lower. There are four levels: hypothermia, general, fever / hyperthermia, and hyperpyrexia.

Hypothermia occurs when the body temperature drops fast than the body can produce heat, resulting in a dangerous drop in temperature.

The average range (97 to 99 F) depends on the person and his or her activities.

Hyperthermia is a low-grade fever, which is typical of low-grade infectious diseases and adverse drug reactions.

Hyperpyrexia manifests itself as a high fever and is usually caused by cerebral hemorrhage, sepsis, or severe infection.

Fever can develop some body health issue

  • Infection: This is the most common cause of the flu. The infection can affect the whole body or one part of the body.
  • Medications: These include antibiotics, opioids, antihistamines, and many more. This is “drug fever.” Medications such as antibiotics increase direct body temperature. Some medicines keep the body from resetting its temperature while other substances cause the temperature to rise.
  • Severe trauma or injury: These may include heart attack, stroke, fever, or fever.
  • Other medical conditions:  These include arthritis, hyperthyroidism, and even other cancers, such as leukemia and lung cancer.

Difference between Fewer and Normal body temperature

Fever : 

A fever occurs when the body temperature is above normal, usually in response to an infection in the body. This is the reason why people sometimes refer to a fever as “fever”.

The fever is not caused by an infection or a disease, but rather it is a part of the body, the immune system and it is a sign that the body is working to get better and better. Do you have a fever when you are sick with a virus such as the flu or a bacterial infection?

Temperature

The body temperature is usually around 36-37°C.

“Normal” body temperature can vary depending on age, that you know what you are doing, and it’s the time of the day, the body temperature may be higher if you’re involved in the sport, and the body has the tendency to be before dawn today, and the greatest of the day.

If you want to know the normal temperature of the body, and take your temperature with a thermometer for the next few days, as long as you like. This will give you a pretty good idea of what the temperature of your body and it has a tendency to be. 

If you have a fever, your body temperature is higher than normal. at a temperature over 38°C, which is a sign of a fever.

Side effects of fever

Fever is rarely dangerous, but it might cause discomfort.

The temperature increases, you may experience shaking chills, or tremors, as if the temperature drops, it is possible that you will have to sweat.

A high fever can cause febrile convulsions (seizures) in children. It occurs in approximately 3% of all children in the age range of 6 months to 5 years of age. 

Almost all the children who are suffering from febrile seizures will grow out of them when they are 4-5 years old. 

Febrile seizures do not lead to long-term health problems, but you should talk to your health care provider if your child has one.

When to call a doctor?

  • You have a temperature over 103°F (39.4°C).
  • You’ve had a fever for more than 3 days straight.
  • If you have fever with –
  • vomiting
  • headache
  • chest pain
  • difficulty breathing

Call doctor if your child has fever and –

  • an unexplained rash
  • repeated vomiting and diarrhea
  • signs of dehydration

Conclusion

The ideal body temperature for adults is about 98.6 ° F, but this varies according to age, gender, physical activity, and health. Body temperature fluctuates throughout the day. Temperatures above 100.4 ° F show fever.

Children may have higher body temperatures than adults, but even a small fever in children can state a serious infection.

A study of the temperature taken from different parts of the body gives different body temperatures that doctors see as normal. Visual reading is higher than oral reading, and armpit reading is often reduced.If a person has a high or low temperature, they should seek medical attention immediately.
