what is normal temp

Normal human body temperature isn’t one exact number, but a range : for most healthy adults, about 97°F to 99°F (36.1°C to 37.2°C) when measured orally.

Quick Scoop

The basic answer

• Classic “normal” is 98.6°F (37°C), but that’s really an average, not a rule.

• Many people are perfectly fine a bit below or above that, as long as they feel well and have no symptoms.

Normal ranges by method

Because where you measure changes the number slightly:

• Oral (mouth): about 97°F–99°F (36.1°C–37.2°C).

• Rectal (bottom): usually about 0.5°F–1°F higher than oral.

• Armpit (axillary): often about 0.5°F–1°F lower than oral.

• Ear (tympanic): roughly 95.7°F–100°F in adults is generally considered normal.

When it’s a fever

• In adults, a temperature of 100.4°F (38°C) or higher is typically considered a fever.

• For very young babies (under 3 months), 100.4°F (38°C) or higher (rectal) is an emergency sign and needs urgent medical attention.

Things that can change your temp

Your temperature naturally goes up and down during the day and with life factors:

• Time of day: lowest in the early morning, highest late afternoon/evening.

• Activity, exercise, hot environment, and spicy food can push it higher temporarily.

• Age: older adults tend to run a bit cooler; babies and kids can have a slightly wider normal range.

Quick “should I worry?” guide

• Around 97°F–99°F, you feel fine → usually normal for most people.

• 99°F–100.3°F, mild elevation → can be early infection, heat, or just your personal normal; watch symptoms.

• 100.4°F or higher → fever; if it persists, is very high, or you feel very unwell, contact a doctor.

If you tell me your exact number, how you took it, and any symptoms (chills, cough, pain, etc.), I can help you interpret it more specifically.
