Can Anxiety Increase Body Temperature

Don't Miss

Fever Alone Is Only Rarely Harmful And Usually Remains Below 1058 Degrees

Our brain knows when our body is getting too hot and is wonderfully designed to regulate our temperature, keeping fevers due to infection from going over 103 degrees or 104 degrees. They rarely go to 105 degrees or 106 degrees.

While these are high fevers, you dont need to be alarmed because fevers with infections dont rise high enough to cause brain damage. When your body temperature rises above 108 degrees, it is possible to get brain damage. But temperatures that cause brain damage are caused by surrounding temperatures being high like the inside of a car, with the windows up on a hot summer day.

Red Pepper Can Cause Higher Core Body Temperature

Like your food spicy? It may raise your body temperature and your metabolism. A study published in Physiology and Behavior had participants add about 1 gram of red pepper to their food. Their core body temperature rose, but their skin temperature was lower. Study authors theorize that this increased heat production along with decreased sensations of appetite demonstrates a potential benefit of consuming red pepper for those who are trying to manage their weight, especially for people who dont usually eat spicy foods.

Anxious A Lot Check Your Body Temperature

Are you becoming more anxious, shaky, or confused when faced with stressor even for no apparent reason at all? If so, check your body temperature. Its possible your metabolism has slowed down, making you more vulnerable to surges of adrenaline that come with even slight amounts of stress. Anxiety has a very real physical component that can explain why you might be having a hard time maintaining balance with lifes ups and downs.

Research shows that anxiety is more common in people with thyroid problems, both hyper- and hypothyroidism. Hyperthyroid is well known for causing rapid or irregular heart rate, nervousness, anxiety and irritability, sweating, and tremors.  But even slightly low thyroid function can have its own subtle symptoms, including anxiety, depression and irritability. Low thyroid activity leads to slowed metabolism and lower body temperature. It impairs the bodys ability to produce important calming neurotransmitters, including GABA and serotonin.  In fact, mood changes may be one of earliest symptoms of impaired thyroid function. Its even been suggested that some people may have brain hypothyroidism while the rest of their body is, essentially, normal. This could be due to defects in thyroid receptor sites in brain cells, or in thyroid hormone transport and uptake into brain cells. Its also been suggested that stress hormones inhibit the conversion of T4 to T3, the active form of thyroid hormone.

Factors That Influence Your Body Temperature

Body temperature has long been recognised as a key indicator of health. Far from being a standard quantity, human body temperature is extremely variable and can vary depending on a number of factors.

Doctors have used body temperature as a measure of illness for centuries. For the better part of two centuries, western medicine held normal body temperature or normothermia to be 37°C-38°C . Since then however, our understanding of normothermia has evolved. We now understand that body temperature, far from being consistent throughout, actually refers to a hodgepodge of different temperatures at different locations in the body. For example, if you measure your rectal temperature, you are likely to get a reading thats higher than an oral measurement. This is because your body is an open system that is constantly interacting with the external environment. At the surface level, the temperature of the body is directly influenced by the ambient temperature. But despite the many factors that influence temperature, your body maintains its core temperature fairly constant.

Core temperature refers to the temperature of the inner organs of the body. The body uses a wide range of mechanisms to ensure that core temperature is maintained within a narrow range that is most suited for the various reactions involved in the bodys metabolic process.

What Is Considered A Fever

LOOK: How Body Temperature Changes When You

A typical body temperature for a healthy child is between 97.7 degrees and 99.5 degrees. However, everyones temperature peaks around 6 p.m., we just dont recognize it when were healthy.

So, if your child already has a fever, and they normally have a rise in body temperature every evening, the addition of the bodys normal temperature increase to the fever causes that spike in the evenings. Unfortunately, thats usually when the doctors offices have closed for the day.

Also, children dont sweat as much as adults. They can feel warm for many reasons crying, playing, teething, snuggling in a warm bed or hot weather. Their body is radiating heat. Feeling their forehead is not enough. You need to take their temperature to get an accurate reading.

The American Academy of Pediatrics recommends you use a digital thermometer. Its best to take the temperature rectally for children ages three and younger. A rectal temperature of more than 100.4 degrees is considered a fever. When taken orally, a temperature higher than 99.5 degrees is diagnosed as a fever.

Typically, if your child is behaving normally, there is no need for any fever-lowering treatment. The AAP recommends you check with your health care provider if:

  • Younger than age 2: Fever lasts more than 24 hours
  • Ages 2 and older: Fever lasts more than 72 hours
  • Blue lips, tongue or nails
  • Preventing Anxiety Body Temperature Alterations

    There are only some aspects of body temperature that you can control. Rapid cold chills, for example, are a specific part of your fight or flight response. They can’t be directly controlled, but generally, they don’t need to be since they tend to fade fairly quickly after the anxiety has faded.

    But when you find that you’re getting too hot or cold, and it’s lasting for a long period of time, there are several things you can do:

    You may even want to drink water as well, which can help control your body temperature from the inside instead of just focusing on the outside. Some people find that showers also help.

    Benefits Of Regular Exercise In Mood Management

    People who are stressed are more likely to experience anger. Numerous worldwide studies have documented that regular exercise can improve mood and reduce stress levels. This may be because physical exertion burns up stress chemicals, and it also boosts production of mood-regulating neurotransmitters in the brain, including endorphins and catecholamines.

    Causes Of Increased Body Temperature You Shouldnt Neglect

    Body temperature is one of the most important physiological parameters that indicate the state of the body. There are many diseases that are accompanied by increased body temperature. This means that your body is fighting against infections or viruses.

    However, there are a lot of dangerous infections and conditions that dont cause symptoms except increased body temperature. In this article, we gathered six causes of increased body temperature you shouldnt neglect.

    What To Do In Case Of ‘internal Fever’

    When you think you have an ‘internal fever’ you should take a warm bath and lie down and rest. Often the cause of this fever sensation is stress and anxiety attacks, which can also cause tremors throughout the body.

    The taking of fever-lowering medication, such as acetaminophen or ibuprofen, is only recommended under medical advice and when the thermometer registers at least 38.5 °C. If, as in the case of ‘internal fever, the thermometer does not show this temperature, no medication should be taken to try to fight a fever that does not exist. So, if necessary, you should just take off your excess clothes and take a bath in warm water to try to lower body temperature and alleviate discomfort.

    If symptoms persist, you should see your doctor for a physical exam to find out what may be happening. In addition to blood and urine tests, your doctor may also order a chest X-ray, for example, to check for any lung changes that may be causing this sensation of fever.

    About The Name Psychogenic Fever Why Not Functional Hyperthermia

    I propose to call psychological stress-associated high Tc functional hyperthermia instead of psychogenic fever. This is in part because psychological stress-associated high Tc is induced by mechanisms distinct from infection/inflammation-associated fever, where proinflammatory mediators play a pivotal role. Furthermore, psychogenic sounds stigmatic for some patients and their families. I do not want to call their high Tc emotional hyperthermia, either, because it sounds like a physiological response, which does not require treatment. I prefer to call it functional because in the clinical setting the naming of diseases including the term functional, such as functional dyspepsia, functional gastrointestinal disorders, or functional somatic syndrome, connotes both stress-related pathology and impaired functioning of the autonomic nervous system.

    How Can I Eliminate Feeling Cold Even If I Know It Is Caused By Anxiety

    The best way to relieve anxiety-induced cold is to do what you always do when you feel cold. Dress warmer, get up and move around, turn on the heat if you need to. This works even if you know that you are feeling cold due to anxiety. Cold feels unpleasant regardless of its cause, and the warmer you are, the less cold you will experience.

    Expressing Anger In Healthy Ways

    Suggestions on how to express your anger in healthy ways include:

    • If you feel out of control, walk away from the situation temporarily, until you cool down.
    • Recognise and accept the emotion as normal and part of life.
    • Try to pinpoint the exact reasons why you feel angry.
    • Once you have identified the problem, consider coming up with different strategies for how to remedy the situation.
    • Do something physical, such as going for a run or playing sport.
    • Talk to someone you trust about how youre feeling.

    The Reason Why Anxiety Can Cause A Change In Body Temperature

    Body Temperature

    Normal body temperature on average is approximately 98.6°F. It’s quite common, however, for body temperature to fluctuate 1°F one way or the other. This fluctuation can occur for a number of reasons. For example, if you’re quiet and relaxed, your body temperature may drop a bit. But if you’re active and racing around during the day, it may elevate to the higher end within the normal range.

    Other factors that affect body temperature include metabolic rate, weight, exercise, age, hormones, pregnancy, and gender.

    The body’s biological clock also affects body temperature. For example, prior to going to sleep the body cools its body temperature somewhat to help bring on sleep. As we wake up, the biological clock increases body temperature so that we can function normally during the day.

    There are other factors that can affect body temperature, including:

    • Medications – antibiotics, narcotics, and antihistamines
    • Medical conditions – heart condition, heart attack, cancer, leukemia, and Hodgkin’s lymphoma
    • Exposure to cold
    • Shock
    • Drug use
    • Metabolic disorders – diabetes and hyperthyroidism

    How you take your body temperature may also produce varying results. For example, rectal or tympanic temperatures are normally as much as 1°F higher than oral temperatures. Axillary temperature may be as much as 1°F lower than oral temperatures.

    What Is Psychogenic Fever

    Among those who develop episodic or persistent high core body temperature without any inflammatory causes, there are patients whose high Tc is associated with psychological stress. Some patients develop a high fever when they are exposed to emotional events , whereas others show a persistent low-grade fever lasting months and even years, either during or after situations of chronic stress . The existence of such patients has been recognized since the early twentieth century and their high Tc has been called psychogenic fever or neurogenic fever. Psychogenic fever is bothersome for both patients and physicians because, although many patients consider the fever to be disabling, there is no abnormal finding to account for their high Tc and antipyretic drugs do not reduce their fever. Moreover, there are still physicians who do not recognize the fact that psychological stress can cause high Tc.

    Exercise Or Physical Exertion

    Your muscles need energy to function. During strenuous physical activity, your muscles generate a tremendous amount of heat, which results in an increase in your body temperature. The body tries to dissipate the excess heat in order to restore the body to a normothermic state. However, sometimes, the body finds itself unable to cope with the increase in temperature and lose enough heat to maintain the core temperature stable.

    The more work your muscles are required to do, the more heat they generate. The extent to which your body temperature climbs during exercise is linked both to the intensity of the activity and the amount of heat lost by your body. Training in hot/humid conditions makes it harder for the body to keep its core temperature within the normal range. This paves the way for dehydration and/or heat illness, which is extremely dangerous. This is why experts warn against intense exercise in hot weather. The more your body is conditioned to a certain level of physical activity, the better it is at being able to dissipate heat. So, the key takeaways from this should be to be patient and take your time with conditioning your body and to hydrate adequately before intense workouts.

    What Should You Do If You Have A Fever

    If you have a fever, your best course of action is to reach out to your medical provider. It can be challenging to determine if your fever is related to stress and anxiety or something else. If the fever is anxiety-related, it will pass as soon as the panic attack or anxious period is over. If you are unsure, reach out to your doctor for more information.

    Physical Symptoms Of Panic Attacks:

    • Feeling faint, dizzy or light-headed  
    • Chest pains and shortness of breath – a tightness of the chest and feeling as though its a struggle to breathe
    • A racing or pounding heart
    • Hyperventilating

    What Should You Do If You Feel You Have A Fever

    If you are someone that is simply experiencing the symptoms of a fever without the fever itself then rest assured you are not alone. Many people that suffer from anxiety attacks have bouts of physical symptoms that feel exactly like fighting a fever. Your best bet is to respond to your anxiety attacks directly.

    First, take hold of your breathing to make sure that you’re not hyperventilating. Hyperventilation drastically increases some of the symptoms that mimic a fever, and can increase your anxiety as well. If you’re feeling ill, get up and walk around a bit too. Sometimes taking yourself out of your situation is valuable for controlling the anxiety.  


    Severe anxiety may be able to cause short term low grade fever during the peak of a panic attack, but this is typically rare. More common is for an individual to have fever-like symptoms, or to feel additional anxiety when they find themselves with a fever of any kind. Only a doctor can diagnose the cause of a fever, but if youre struggling with severe anxiety, anxiety reduction will help.

    Changes In Digestive Function

    Cortisol blocks processes that the body considers nonessential in a fight or flight situation.

    One of these blocked processes is digestion. Also, adrenaline reduces blood flow and relaxes the stomach muscles.

    As a result, a person with anxiety may experience nausea, diarrhea, and a feeling that the stomach is churning. They may also lose their appetite.

    suggests that stress and depression are linked to several digestive diseases, including irritable bowel syndrome .

    One , of outpatients at a gastroenterology clinic in Mumbai, reported that 3040 percent of participants with IBS also had anxiety or depression.

    A Mechanism Behind Increased Body Temperature With Stress

    Shivering is one mechanism by which heat is produced in the body. Heat production is called thermogenesis. Another mechanism is through nonshivering thermogenesis regulated by brown fat . This second type of heating mechanism kicks in when we need extra heat production such as a postnatal infant, someone developing a fever, an animal arousing from hibernation, eating, or in the case of the current study, stress.

    A recent study published in the American Journal of Physiology provides evidence that during stressful events brown adipose tissue can elevate body temperature through nonshivering thermogenesis. Prior to this study the role of brown adipose tissue in regulating emotional hyperthermia was uncertain.

    Behavioural/social Symptoms Of Panic Attacks:

    15 Ways To Increase Body Temperature For Optimum Health

    • Social withdrawal and isolation not wanting to meet with family and friends, in order to try and hide your condition and reduce the chances of a panic attack occurring
    • Reduced school or work performance
    • Inability to manage day-to-day tasks effectively
    • Frequent visits to emergency departments
    • Seeing your GP more than usual

    The Only Way To Cure Body Temperature Changes

    Still, the most important thing to realize is that when anxiety is causing these changes to your body temperature, the only thing that is likely to stop them completely is something that addresses your underlying anxiety. That’s why I highly recommend you seek out an anxiety treatment that focuses on your symptoms and addresses your individual needs.


    Anxiety movies blood away from the muscles, causes sweating, and leads to changes in blood pressure. All of these affect your perceived temperature. There are some minor changes one can make to feel more comfortable, but reducing anxiety is going to be the priority.

    Things To Know About Fevers

    There are times when a fever can lead to a febrile seizure or convulsion particularly in children between the ages of three months and five years. Although scary, febrile seizures usually only last a few minutes and are not dangerous, but you should still inform your health care provider.

    Its also important to tell your pediatrician if your child develops a fever after traveling. Special tests can be ordered to find out if your child picked up an infection while on your trip.

    What Can I Do To Prevent Feeling Cold When Stressed

    The best thing to do is to address your stress issues. Reducing stress and anxiety can help diminish and ultimately eliminate body temperature change. Regular deep relaxation, regular exercise, relax through the art of painting, and meditation can also help to alleviate fluctuating body temperatures.

    Unhelpful Ways To Deal With Anger

    Many people express their anger in inappropriate and harmful ways, including:

    • anger explosions some people have very little control over their anger and tend to explode in rages. Raging anger may lead to physical abuse or violence. A person who doesnt control their temper can isolate themselves from family and friends. Some people who fly into rages have low self-esteem, and use their anger as a way to manipulate others and feel powerful. For more information, see What is violence against women? on the White Ribbon Australia website
    • anger repression some people consider that anger is an inappropriate or bad emotion and choose to suppress it. However, bottled anger often turns into depression and anxiety. Some people vent their bottled anger at innocent parties, such as children or pets. 

    Feeling Feverish It Might Be Stress

    Psychogenic fever is a stress-related, psychosomatic condition that manifests itself in a high body temperature. It is caused by exposure to emotional events or to chronic stress. A new review introduces recent findings from recent research and clinical experience regarding the disease.

    Psychogenic fever is a stress-related, psychosomatic condition that manifests itself in a high body temperature. It is caused by exposure to emotional events or to chronic stress. Dr. Takakazu Oka, of the Kyushu University Graduate School of Medical Sciences, specializes in psychosomatic medicine and treats patients with psychogenic fevers. In his review article “Psychogenic fever: how psychological stress affects body temperature in the clinical population,” published in the journal Temperature, Dr. Oka introduces his recent findings from his research and clinical experience regarding the disease.

    “While this condition is known in the literature, only a few doctors in the world study it and treat patients with psychogenic fevers,” says Professor Andrej Romanovsky, of St. Joseph’s Hospital and Medical Center in Arizona, and the Editor-in-Chief of Temperature, “this is why we have invited Dr. Oka to share his unique experience.”

    How To Tell If Stress Is Causing Your Fever

    A psychogenic fever exhibits many of the typical fever symptoms, such as: 

    • Body chills or aches
    • Fatigue 

    In the case of acute stress, like if you suddenly receive bad news or experience the death of a loved one, you might feel these symptoms and recognize a psychogenic fever. But cases are rarely so clear cut. That’s especially true with chronic stress, like taking care of a loved one who is ill, which can build up over time and result in psychogenic fever symptoms. 

    To diagnose psychogenic fever, other physical causes of fever must be ruled out, Miller Parrish says. It’s important to note that fever most commonly occurs with illness or injury. So, if you’re also experiencing symptoms like nasal congestion or coughing with fever, it’s likely indicating an underlying cause for the fever other than stress, like the cold or flu. 

    If you experience fever regularly but can’t easily identify the underlying cause like an illness or injury you should keep a fever journal, Miller Parrish says. Record what temperature you’re experiencing, the symptoms you have, and how long the fever lasts. If the unexplained fever continues, you should see a doctor. 

    “If that persists for days to weeks, it would be prudent to see a doctor to rule out causes that need medical treatment,” Miller Parrish says. “If those causes are ruled out or treated and the high temperatures persist, other psychological and de-stressing interventions may help.” 

    Can Stress Cause Fever

    Excessive Sweating In Social Situations? Know The Causes ...

    First, let’s be clear on what a “fever” even is: According to the US National Library of Medicine’s MedlinePlus resource, “An adult probably has a fever when the temperature is above 99°F to 99.5°F , depending on the time of day.” While normal body temperature is thought to be around 98.6°F, a normal range, per MedlinePlus, is anywhere from 97°F to 99°F.

    While a fever is a sign of an infection or other illness, there isnt a substantial body of research that proves any association between stress and a rise in body temperature, Donald Ford, MD, a family medicine physician at Cleveland Clinic, tells Health. Stress can cause some physiologic changes blushing, turning red, Dr. Ford explains. thats very superficial. It doesnt alter the core body temperature.”

    Ramiro Jervis, MD, an internal medicine doctor at the Family Health Centers at NYU Langone, adds that he’s “not aware of any studies that stress itself can cause fever.” He also tells Health that if a patient presents with a fever, their doctor is likeliest to look for causes other than stress, such as an infection.
