Temperature 38 lasts 5 days in adults and children: causes and what to do

Why does the temperature rise: common reasons

An increase in body temperature above 37 ᵒC for a long time in the scientific literature is usually called low-grade body temperature. Often, an increase in body temperature indicates the presence of a hidden inflammatory process in the body.

ARVI and other viral infections are also accompanied by elevated body temperature, fever, body aches and other signs of a cold.

However, it is not clear what to do if the temperature is elevated and there are no other symptoms indicating the presence of the disease. The first and most important action if you have a low-grade fever for a long time is to consult a doctor to find out the cause of this phenomenon.

This is influenced by many factors:

1. Temperature measurement location. Thus, measurements are carried out in the armpit, where the norm is 36.6 ᵒC, in the mouth the norm is 37-37.3 ᵒC, and measurements can also be carried out rectally or in the ear, where the norm will be up to 37.5 ᵒC.
2. Floor. In men, body temperature is 0.5 - 0.7 ᵒC lower than in women. At the same time, during the menstrual cycle or pregnancy, a woman’s body temperature fluctuates up or down.
3. Age. In newborns and small children, the temperature regime in the body has not yet been fully established. In girls, body temperature becomes stable by adolescence, and in boys by adulthood. In addition, during menopause, a low-grade fever may rise above a woman's usual normal temperature.
4. Times of Day. As a rule, the temperature in the morning is lower than in the evening.
5. Psychophysical and emotional state of a person. With severe fatigue, lack of sleep, or anxiety, body temperature can drop to 35 ᵒC. During high physical activity, severe stress, fear or prolonged mental stress, the temperature may rise by several degrees.
6. Individual characteristics of a particular person whose body is healthy at a body temperature that is outside the normal range.
7. Residual symptoms after illness.
8. Side effects from the use of medications.

It is generally accepted that the normal human body temperature should be 36.6 ᵒC. As soon as the indicator rises, and especially exceeds 37, a person begins to look for the reason for the rise in temperature. However, it is not entirely correct to consider the reading of 36.6 as the only normal one. The temperature of the human body can fluctuate during the day from 0.5 to 1 ᵒC.

Why does a subferile temperature remain after ARVI of 37?

A cold is a general term for many simple respiratory tract infections that can cause a sore throat and nasal discharge.

This term is used by people far from medicine. In medicine, this phenomenon is called ARVI. It often happens that a temperature of 37 degrees lasts for several days after a cold? Why does this happen?

This temperature is called low-grade fever; it can occur after a person has suffered from acute respiratory viral infection.

Most often, this phenomenon occurs in adults, but there are cases of its occurrence in children. Why does a temperature of 37 C appear after an acute respiratory viral infection and persist for several days?

Symptoms and signs of a cold

It can be very difficult to determine on your own what virus caused ARVI. But if you consult a doctor, you can thoroughly determine the symptoms:

• The first and most obvious sign of ARVI is the presence of a runny nose. If there is a possibility that the swelling has formed as a result of an allergy, then attention should be paid to the accompanying signs of the disease;
• Sore and sore throat;
• Low temperature, which stays at around 37-38 C;
• A few days later the patient develops a runny nose and cough.

First signs of a cold

Most often, it all starts with nasal congestion; on the first day, nasal discharge is liquid and clear.
The discharge can be quite profuse, causing sneezing, red eyes and an itchy nose. After a day from the moment of infection with ARVI, the secretion becomes viscous and thick, darker in color. You should not be afraid of this phenomenon, because it indicates that recovery is approaching.

The body begins to intensively fight the disease; leukocytes, the main enemies of the virus, die in the nose, giving the nasal mucus its color. You should not take antibiotics at this time.

It is important to understand the differences between an allergic reaction and a cold, because in both cases signs characteristic of ARVI may be observed. At the same time, an allergic reaction can last a long time, without going away after treatment with conventional ARVI drugs.

That is why it is extremely important to determine exactly what is the cause of deterioration in health by choosing the right treatment.

Fever without signs of a cold

It happens that the temperature remains at a fairly high level, but no signs of ARVI are observed. This may indicate the presence of various, quite serious diseases that may have nothing to do with viral ones.

Fever can be accompanied by various symptoms: weakness, chills, pain in the eyes, body aches.

High temperature can be caused by various diseases, not only the entry of the ARVI virus into the body:

• Bacterial causes, for example, meningitis, tonsillitis, pyelonephritis;
• Infections: HIV, typhoid, tuberculosis;
• Parasitic and fungal infections: candidiasis, malaria, mononucleosis;
• Oncology: leukemia, lymphomas, tumors;
• Systemic inflammation: lupus, arthritis, rheumatism.

It is for this reason that if there is a high temperature without other accompanying symptoms, this may indicate the presence of serious diseases.

In this case, you should not hesitate to consult a doctor, because only he can conduct the necessary research, prescribe tests and make an accurate diagnosis. In this case, it is better not to postpone the examination.

The main causes of colds

When talking about a cold, referring specifically to ARVI, the only reason for its appearance is the virus; there can be no other options in this case.
At the same time, the virus itself does not begin life in every cell, but only in the one that could not provide the necessary resistance to it. It is for this reason that, speaking about indirect factors that can cause colds in humans, the following can be noted:

• Colds after hypothermia, especially in hot weather. Sometimes it is enough to eat ice cream, and after a few hours the signs of a cold appear on your face. The blood vessels of an unprepared person are not able to adapt, actively reacting to temperature changes, this leads to redness in the throat and a runny nose;
• Stress can also be an indirect culprit for a cold. Many people regard this reason as unworthy of attention, but in reality this is far from the case. Nervous stress can negatively affect the immune system, which is what provokes frequent colds that bother people both in summer and winter;
• Acute form of any chronic disease. It disrupts the normal balance in the body, leading to a weakened immune system. Quite often there are situations when, against the background of diabetes mellitus or peptic ulcer disease, a person begins to often encounter colds;
• Poor nutrition, drinking alcohol, poisoning, smoking - all of this has a negative impact on the immune system. By eliminating all the factors described above, you can forget about colds forever.

All these circumstances can negatively affect the human body, which leads to the activation of viruses, they begin to attack cells that do not have any protection. The weaker the immune system, the less strength a person has to resist infections and the more often he encounters colds.

Causes of frequent colds

If an adult gets a cold twice a year, then there is nothing to worry about. But if the disease occurs up to five or more times, with low-grade fever and other complications occurring, then this indicates the presence of serious health problems.

Signs indicating weak defenses of the body are manifested in the following:

1. Exacerbations of chronic diseases.
2. Frequent colds.
3. Unmotivated aggression.
4. Excessive fatigue, sleep disturbances, weakness.
5. Malfunctions of the gastrointestinal tract.
6. Visible changes in the skin: peeling, dryness.

To prevent colds from occurring every two months, efforts must be made to normalize the immune system. Physiological methods include proper nutrition, which must necessarily include fermented milk products, protein foods, vitamins, you need to play sports, harden yourself and maintain a correct daily routine.

Pharmacological methods include increasing the body's resistance to viruses, taking natural adaptogens, for example, ginseng and echinacea, as well as homeopathic remedies and prebiotics.

If we talk about immunomodulators, then before you start taking them, you should definitely consult with your doctor.

The temperature remains at 37 C after a cold

Quite often, after suffering from a cold, a subfebrile temperature remains, which remains at around 37 C. If a subfebrile temperature of 37-37.2 C occurs, you need to pay attention to the following indicators:

• Are there any disturbances in general health;
• Are there still signs of a cold after two or more weeks?
• Are there any symptoms indicating complications after a cold?

According to many doctors, after a series of severe infectious diseases, a low-grade fever of 37 C can last for two weeks. If you have such a low-grade fever, then it is recommended to adhere to this daily regimen, while eliminating the use of medications:

1. If possible, it is recommended to spend more time at home, try to rest, avoid eating fatty foods and try to drink as much fluid as possible.
2. If it is necessary to go to work, then it is necessary to avoid excessive physical exertion, as this can negatively affect the functioning of blood vessels and the heart.
3. You can support the body with the help of various decoctions and herbal teas.

Such methods will be effective if there is a low-grade fever not exceeding 37-37.2 C, despite the fact that there is no general impairment of the condition.
In this case, it is important to know how to determine body temperature without a thermometer. If your health worsens, you must urgently consult a doctor for an examination and a correct diagnosis in order to effectively treat. As a rule, in this case, a general blood test is prescribed, which is considered the most informative. With its help, you can determine and also prevent the possible onset of complications in the body.

Colds occur in all people. Symptoms may be expressed to a greater or lesser extent, but in any case, ARVI remains characteristic: sore throat, runny nose and a slight increase in temperature. The reason that can cause the disease is a virus that enters the human body.

You need to understand that under the mask of a simple ARVI, something else, a formidable disease, for example, influenza, may be hiding. For this reason, it is extremely important to know what symptoms accompany ARVI. Against the background of immunity weakened by a number of factors, colds can occur much more often than in ordinary people.

This condition can cause complications that may require medical attention. Understanding what happens in the human body during a cold, you can always provide him with timely assistance, increasing the chances of fighting the infection. In this case, the main thing is timely treatment and compliance with certain rules to make you feel better. Everything you need to know about temperature is in the video in this article.

What causes elevated body temperature without signs of a cold?

In addition to the above factors that influence an increase in a person’s temperature, a possible cause may also be the presence of any disease, inflammation or infection. Low-grade fever is such a common symptom that there are a huge number of variants of diseases that can cause it.

The most common diseases that cause an increase in body temperature can be identified:

• Diseases in the field of otolaryngology: laryngitis, tonsillitis, sinusitis, ARVI;
• Diseases of the gastrointestinal tract: cholecystitis, gastritis, ulcers;
• Inflammatory diseases in the male and female sphere;
• Kidney diseases: cystitis, pyelonephritis;
• Caries;
• Worm infestation;
• Tuberculosis;
• HIV infection;
• Hepatitis;
• Thyroid diseases;
• Autoimmune diseases;
• Presence of neoplasms;
• Allergic reactions.

Many of these diseases are accompanied by various symptoms, in addition to fever, but which may not be noticed at first glance. Not to mention their internal manifestations, which can only be detected with a careful study of the overall clinical picture and test results.

What to do if an adult has a high fever without symptoms

If an adult has a high asymptomatic temperature for a long time or there is a sharp increase in temperature, it is important to immediately consult a doctor. Depending on how high the temperature has risen, the doctor will take the necessary measures to stabilize it, after which he will prescribe a series of initial tests. The main goal in diagnosing such a condition is to exclude diseases that are dangerous to humans and to find out its main cause.

Basic actions for prolonged high body temperature:

1. Take a general blood test and a general urine test. Indicators in the test results will be able to tell the doctor about the presence or absence of inflammation in the body (for example, ESR or leukocyte formula).
2. Seek advice from specialized specialists: otolaryngologist, surgeon, dentist, gastroenterologist, gynecologist, etc.
3. If you have doubts in any area, undergo additional diagnostic methods: ultrasound, radiography, CT of a certain area, MRI, etc.

The sooner the doctor answers these questions, the faster he can help. Most likely, it is simply a matter of lifestyle, stress, or heredity in general, but appropriate diagnosis is necessary to clarify these factors.

What to do at a temperature of 37

If a person has a cold and feels unwell, measures must be taken. Firstly, you need to rest more, stay in bed and drink plenty of water, compotes, fruit drinks. You also need to urgently consult a doctor, who will find out why the temperature persists and tell you what to do and what medicine to take.

If a temperature of 37 is not accompanied by other symptoms, then you need:

• Introduce fruit products enriched with ascorbic acid into the menu;
• Get enough sleep and rest;
• Do not take antipyretics.

If the temperature does not go away, the person is freezing, and negative symptoms have developed, then you need to call an ambulance.

Causes of temperature 37: lasts a month in an adult

In the rhythm of modern life, people often forget to pay attention to their health. As often happens, elevated body temperature in an adult is not a strong cause for concern. Several days, weeks or even months pass before you contact a specialist.

The reasons for such a prolonged increase in body temperature beyond 37 ᵒ C may be:

• Inflammatory processes in the body;
• Residual effects from recent illnesses that may last for several months;
• Constant stress;
• Infection with helminths;
• Various diseases of the human body: from ENT diseases to diseases of the heart, blood vessels and thyroid gland.

Perhaps the main key to successful treatment of most diseases is timely consultation with a doctor and appropriate diagnosis. Parents try to find the causes of this condition and select treatment for their baby as soon as possible for his recovery.

When a child has a fever, it is stressful for the whole family.

Usually, along with the temperature, there are symptoms such as runny nose, cough, sore throat, hoarseness, headache, etc. All these symptoms indicate the presence of a cold, and in this situation, the doctor, after examination, will quickly recommend the necessary treatment.

Increased body temperature without symptoms in children: causes and treatment

In a situation where the child’s body temperature is elevated and there are no other obvious symptoms, parents begin to get seriously worried. As is the case with adults, children's body temperature can also fluctuate and have understandable reasons.

It is influenced by the child’s age, time of day, the presence of anxiety or stress (for example, kindergarten or school), recent illnesses and associated residual effects.

However, an elevated body temperature in a child may also indicate the presence of a possible pathology in the body or an asymptomatic course of an infectious disease.

The main diseases that should be excluded from possible causes of low-grade fever:

• Infection with helminths;
• Tuberculosis;
• Pneumonia;
• Inflammation of the genitourinary system;
• Diseases of the gastrointestinal tract;
• Diseases of the cardiovascular system;
• Hepatitis;
• Diseases of the ENT organs.

After finding out the reasons for the child’s elevated temperature, it will become clear whether treatment is necessary in a particular situation or whether low-grade fever is a manifestation of the norm.

Cold symptoms

Colds are a general name to define a number of uncomplicated respiratory infections that cause inflammation of the nasopharyngeal mucosa. However, in this context, the definition is used by people who are far from medical practice. If you turn to the medical literature in search of the concept of this word, you may read that a cold is a disease caused by hypothermia of the body, and not by viruses. In order to get sick, it is enough to wet your feet in water on the street, freeze while waiting for a minibus, or, for example, drink very cold lemonade.

However, usually when people say: “I have a cold,” they often mean that the body has been infected by a virus.

In medicine, a disease caused by a virus is called ARVI. There are a lot of cold viruses - more than 250. That is why there is no panacea for ARVI. There are not many symptoms of a cold. Nasal congestion makes it clear that a cold is developing; this is the first sign of the disease by which ARVI can be distinguished, for example, from a sore throat. On the first day of development of the disease, the secretion is not cloudy and liquid.

The discharge is strong and quite often causes:

• Sneezing;
• Itchy sensations in the nasal cavity;
• Redness of the eyes.

When a day passes after the onset of ARVI, the secretion thickens. Its color changes. There is no need to be afraid, such a change in color does not mean that a bacterial infection has occurred, but indicates that the body has begun to fight the disease and is recovering. The body is actively fighting the infection, leukocytes die in the nasal cavity and therefore the color of the secretion changes, this is normal. Therefore, there is no need to take antibacterial agents in this case.

It is important to understand the differences between allergies and colds, since in both cases severe nasal discharge, sneezing and itching appear.

But at the same time, the allergic reaction continues for a longer period, sometimes a month or two, and the symptoms of cold pathology disappear already on the 8th day of adequate therapy. Swelling of the mucous membrane upon contact with an allergen manifests itself instantly, while with a cold it does not begin to develop immediately with a gradual deterioration of the condition.

The main difference between an allergic reaction and an acute respiratory viral infection is that with a cold, the temperature always rises, even if only slightly, but with an allergy it does not. With a cold, weakness develops, his eyes become dull, and the person becomes lethargic and apathetic. Only a doctor should treat acute respiratory viral infections or acute respiratory infections. You should contact the clinic immediately after the development of negative symptoms. Otherwise, serious complications may develop.
