You've probably had it drilled into your head that your trunk temperature "should" be 98.half dozen degrees Fahrenheit and that a high or low body temperature signals something is wrong. Just that's not quite true.

In general, normal trunk temperature differs amidst individuals and ranges from about 97 to 99 degrees Fahrenheit (36.ane to 37.2 degrees Celsius) when taken with an oral thermometer, per the U.Due south. National Library of Medicine (NLM). Your normal body temperature varies depending on factors like your age, gender, race and time of day, amid others.

What Does Having Depression Body Temperature Mean?

Here'due south the expert news: A slightly lower-than-normal temperature is normally nothing to worry almost.

In fact, inquiry suggests that average man body temperature may exist decreasing slightly, and that 97.5 degrees Fahrenheit (36.four degrees Celsius) may be a "new normal" temperature, according to Harvard Health Publishing.

This may be due to the fact that we now spend much of our time in temperature-controlled settings, or possibly because of a population-wide drop in metabolic rate or inflammation, per Stanford Medicine.

Just a consistently or very depression trunk temperature — less than 95 degrees Fahrenheit (35 degrees Celsius) — oftentimes signals accidental hypothermia or an underlying medical issue. That's considering having a depression body temperature that'south less than 95 degrees Fahrenheit doesn't provide enough estrus for your centre, nervous system and other organs to function, according to the Mayo Dispensary.

Alert

Hypothermia is medical emergency, then if your temperature less is than 95 degrees Fahrenheit, you should seek care immediately, per the Cleveland Clinic.

What Causes Depression Body Temperature?

In general, low body temperature occurs when the body loses estrus faster than it's able to produce it, co-ordinate to the Cleveland Clinic. Depression body temperature can occur equally a outcome of both external causes (like medication side furnishings, age or cold weather) and internal causes within the torso, such as hormone and nervous system disorders.

Here are several of the other possible causes of depression body temperature, along with when to run across your doctor.

1. Exposure to Cold

Your trunk temperature reflects the balance between the heat your torso generates versus how much it loses. Prolonged exposure to a common cold surround tin potentially lead to hypothermia because of excessive rut loss, co-ordinate to the Mayo Clinic. Infants and seniors are peculiarly susceptible to this status, equally their bodies don't regulate trunk temperature as well as those in other age groups.

Serious hypothermia is more likely to occur in farthermost conditions like if your car breaks down in a blizzard, rather than if yous spend a few hours bundled up at a football game on a cold 24-hour interval.

Still, if you plan to spend time outside in cool or cold weather, apparel in warm wearable and avoid drinking alcohol, equally information technology dilates your superficial blood vessels and increases loss of body heat, per the Mayo Dispensary.

And here's how to care for low body temperature if it's already occurred:

• Go out of the cold
• Remove any wet wear
• Packet upwardly in blankets
• Sip warm beverages
• Avert applying direct heat, like hot h2o

• Hypothyroidism
• Hashimoto's disease
• Endocrine disorders

That'due south because reduced production of hormones can potentially lead to a lower-than-normal body temperature or intolerance to cold. In fact, a low torso temperature sometimes serves as an important clue to a hormonal trouble.

iii. Nervous Organization Disorders

An surface area of your brain called the hypothalamus serves as the primary site of body temperature regulation, according to Rush. It sends messages to the rest of your body that result in either overall rut conservation or loss.

Nervous system disorders can disrupt this temperature regulation or your response to external sources of common cold, leading to a depression body temperature, according to an Apr 2016 review in ​Autonomic Neuroscience​. Examples of these conditions include:

• Stroke
• Spinal cord injury
• Parkinson's disease
• Multiple sclerosis
  

4. Infection or Illness

Nearly people think a fever and infection go hand in hand — and they oft practice.

But you can also accept a low trunk temperature when sick. For instance, a serious infection similar pneumonia sometimes triggers a low body temperature, especially among older adults and people with weakened allowed systems, according to the Mayo Clinic.

Hypothermia associated with a serious infection often indicates a complication called sepsis, which refers to an out-of-control inflammatory response to the infection leading to malfunction of body organs or systems, per the NLM.

Having a low body temperature but feeling hot may likewise be a sign of this condition if accompanied by other sepsis symptoms (like rapid breathing, fast pulse and disorientation), as sepsis can cause fever and sweating.

Warning

Seek medical handling immediately if you lot have signs of sepsis, as developing a low body temperature when you have sepsis typically signals a potentially life-threatening situation, according to an Oct 2016 study in ​Disquisitional Care.​

five. Other Causes

A slight decrease or subnormal temperature is a potential side result of certain medications, including some types of drugs used to care for depression, bipolar disorder and schizophrenia, according to the ​Autonomic Neuroscience​ review.

Additional possible, uncommon causes of depression torso temperature include:

• Anorexia nervosa, per the ​Autonomic Neuroscience​ review
  
• Chronic vitamin B1 deficiency, also known as Wernicke encephalopathy, per the NLM
• Certain skin conditions, such as erythrodermic psoriasis, per the National Psoriasis Foundation
