what body temp is too low
A body temperature under about 95°F (35°C) is considered dangerously low and is called hypothermia ; this is a medical emergency and needs urgent care.
Normal vs. “too low” body temperature
- Normal adult oral temperature is roughly 97°F–99°F (36.1°C–37.2°C), and it can run a bit lower in the morning and in older adults.
- Some people naturally sit a little low (around 97°F/36.1°C), which can still be normal for them if they feel well.
- A reading in the 96°F (35.5°C) range is low, and you should recheck to be sure it is accurate and pay attention to how you feel.
When it becomes dangerous
Doctors generally use these cutoffs for core body temperature (rectal or esophageal in hospital settings):
- Below 95°F (35°C): Hypothermia (too low, not just “a bit cold”).
- Mild hypothermia (89.6°F–95°F / 32°C–35°C): Shivering, feeling very cold, fast pulse, clumsy movements, confusion can appear.
- Moderate hypothermia (82.4°F–89.6°F / 28°C–32°C): Shivering may stop, thinking and speech slow, person may become very drowsy or confused.
- Severe hypothermia (below 82.4°F / 28°C): Very slow or weak pulse, possible loss of consciousness, high risk of cardiac arrest and death.
Any temperature below 95°F (35°C) is too low and can be life‑threatening, especially if the person is confused, very sleepy, or not acting right.
Causes of low body temperature
Low temperature is often linked with being in a cold environment, but it can also happen indoors.
Common causes include:
- Exposure to cold weather, cold water, wet clothing, or wind.
- Hormone problems like hypothyroidism or adrenal insufficiency.
- Serious infections like sepsis , especially in older or very ill people.
- Low blood sugar, malnutrition, or alcohol and some drugs/medications.
- Age extremes (newborns, older adults) and certain medical conditions that reduce the body’s ability to make or conserve heat.
What to do if your temp seems too low
If you or someone else gets a reading that looks low:
- Check again correctly.
- Use a reliable thermometer and follow directions; oral temps can be off if you just drank something hot or cold.
* If one reading is 96°F–97°F but you feel fine, repeat in 10–15 minutes and watch symptoms.
- Seek emergency help right away (call emergency services) if:
- Temperature is 95°F (35°C) or lower , especially if measured more than once.
* The person is confused, very sleepy, slurring words, stumbling, breathing slowly, or has a very slow or weak pulse.
* The person is a baby, older adult, pregnant, or has serious health problems and feels very unwell.
- While waiting for help (for suspected hypothermia):
- Move to a warm, dry place; remove wet clothing and cover with blankets, including the head.
* Provide warm (not hot) drinks if the person is fully awake and able to swallow safely; avoid alcohol or caffeine.
* Do not use very hot water, heating pads directly on the skin, or vigorous rubbing, as these can cause problems in severe hypothermia.
- Call a doctor soon (non‑emergency) if:
- Your temperature repeatedly runs low (for example, under about 96.8°F/36°C) over days.
* You have other symptoms like fatigue, weight gain, depression, or feeling cold all the time, which could suggest thyroid or other hormone issues.
Quick example
Imagine your thermometer shows 96.0°F (35.5°C) and you feel a bit off but are still alert and talking normally.
You would:
- Recheck the temperature after resting indoors, following the thermometer’s instructions.
- If it stays around 96°F but you feel okay, call your regular doctor the same day or next to ask if you need evaluation.
- If it drops toward 95°F (35°C) or you become confused, dizzy, or very sleepy, treat it as an emergency and get immediate medical help.
Bottom line: A little below 98.6°F can be normal, but 95°F (35°C) or lower is too low and can be dangerous , especially with symptoms. Always treat low readings seriously and get medical care if there is any doubt.
