You've probably had it drilled into your head that your torso temperature "should" be 98.6 degrees Fahrenheit and that a loftier or low torso temperature signals something is wrong. But that'south not quite true.
In general, normal body temperature differs amongst individuals and ranges from most 97 to 99 degrees Fahrenheit (36.1 to 37.2 degrees Celsius) when taken with an oral thermometer, per the U.S. National Library of Medicine (NLM). Your normal body temperature varies depending on factors like your historic period, gender, race and time of day, among others.
What Does Having Depression Body Temperature Mean?
Hither'southward the skilful news: A slightly lower-than-normal temperature is usually aught to worry well-nigh.
In fact, inquiry suggests that boilerplate human torso temperature may be decreasing slightly, and that 97.5 degrees Fahrenheit (36.iv degrees Celsius) may be a "new normal" temperature, co-ordinate 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 drib in metabolic rate or inflammation, per Stanford Medicine.
But a consistently or very depression body temperature — less than 95 degrees Fahrenheit (35 degrees Celsius) — often signals accidental hypothermia or an underlying medical upshot. That'southward because having a low body temperature that's less than 95 degrees Fahrenheit doesn't provide plenty rut for your heart, nervous organisation and other organs to office, according to the Mayo Clinic.
Warning
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 Torso Temperature?
In general, depression torso temperature occurs when the body loses heat faster than it'south able to produce it, according to the Cleveland Dispensary. Low body temperature can occur as a issue of both external causes (like medication side furnishings, age or cold weather condition) and internal causes within the body, such as hormone and nervous system disorders.
Here are several of the other possible causes of low body temperature, along with when to see your doctor.
ane. Exposure to Cold
Your body temperature reflects the balance between the heat your body generates versus how much it loses. Prolonged exposure to a cold surround can potentially lead to hypothermia because of excessive oestrus loss, co-ordinate to the Mayo Clinic. Infants and seniors are particularly susceptible to this condition, every bit their bodies don't regulate trunk temperature as well as those in other historic period groups.
Serious hypothermia is more likely to occur in extreme atmospheric condition similar if your car breaks downwardly in a blizzard, rather than if you spend a few hours arranged up at a football on a cold day.
Nevertheless, if yous programme to spend time exterior in cool or cold weather condition, dress in warm clothing and avoid drinking alcohol, every bit information technology dilates your superficial blood vessels and increases loss of body oestrus, per the Mayo Clinic.
And here's how to treat low body temperature if it's already occurred:
- Get out of the cold
- Remove any wet article of clothing
- Parcel upwards in blankets
- Sip warm beverages
- Avert applying direct heat, like hot water
High Blood Pressure and Depression Body Temperature
In general, blood pressure is higher when you're in common cold temperatures and lower in warm temperatures. That'due south considering common cold prompts your blood vessels to narrow, then more pressure level is needed to keep your blood pumping, according to the Mayo Clinic.
2. Hormonal Conditions
Hormones regulate many actual functions, including torso temperature maintenance, co-ordinate to Rush. But per the Cleveland Clinic, if you have any of the following hormonal disorders, it can mess with your temperature and make yous feel too common cold:
- Hypothyroidism
- Hashimoto's disease
- Endocrine disorders
That'due south because reduced production of hormones tin potentially atomic number 82 to a lower-than-normal trunk temperature or intolerance to cold. In fact, a low body temperature sometimes serves as an important clue to a hormonal problem.
3. Nervous System Disorders
An surface area of your brain called the hypothalamus serves as the primary site of body temperature regulation, according to Rush. It sends letters to the rest of your trunk that event in either overall heat conservation or loss.
Nervous arrangement disorders tin can disrupt this temperature regulation or your response to external sources of common cold, leading to a depression body temperature, according to an April 2016 review in Autonomic Neuroscience. Examples of these conditions include:
- Stroke
- Spinal cord injury
- Parkinson'due south disease
- Multiple sclerosis
4. Infection or Affliction
Most people think a fever and infection go mitt in hand — and they often practice.
But you lot tin also accept a low torso temperature when sick. For instance, a serious infection similar pneumonia sometimes triggers a low torso temperature, especially among older adults and people with weakened allowed systems, co-ordinate to the Mayo Clinic.
Hypothermia associated with a serious infection often indicates a complication called sepsis, which refers to an out-of-command 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 also be a sign of this condition if accompanied past other sepsis symptoms (similar rapid breathing, fast pulse and disorientation), as sepsis tin can cause fever and sweating.
Alert
Seek medical treatment immediately if y'all have signs of sepsis, every bit developing a low body temperature when you lot have sepsis typically signals a potentially life-threatening state of affairs, co-ordinate to an October 2016 study in Critical Care.
five. Other Causes
A slight subtract or subnormal temperature is a potential side effect of certain medications, including some types of drugs used to care for depression, bipolar disorder and schizophrenia, co-ordinate to the Autonomic Neuroscience review.
Additional possible, uncommon causes of low body temperature include:
- Anorexia nervosa, per the Autonomic Neuroscience review
- Chronic vitamin B1 deficiency, also known every bit Wernicke encephalopathy, per the NLM
- Sure skin atmospheric condition, such equally erythrodermic psoriasis, per the National Psoriasis Foundation
When to See a Doctor

While it'south important to monitor your vital signs and brand sure they're within normal limits, you don't need to run to the doctor every time your body temperature raises or lowers a degree or two. Every bit mentioned earlier, a temperature as depression every bit 97 degrees Fahrenheit (36 degrees Celsius) can be perfectly normal if yous otherwise feel well.
Merely y'all should see your doctor if your torso temperature is regularly less than 97 degrees Fahrenheit, especially if y'all experience other signs or symptoms, according to the Cleveland Clinic.
Per the Mayo Clinic, call 911 for emergency medical intendance if any alert signs or symptoms indicating possible hypothermia occur, including:
- Shivering
- Slurred speech or mumbling
- Irksome, shallow breathing
- Weak pulse
- Lack of coordination
- Drowsiness
- Confusion
- Memory loss
- Loss of consciousness
- Brilliant scarlet, common cold skin (in babies)
