Normal Vital Signs — Teen (13–18 years)

Teen vital signs are close to adult values, with two common traps: anxiety about being measured (which pushes heart rate and blood pressure up for a few minutes) and caffeine or energy drinks (which do the same for longer). A resting reading, repeated once if the first looks surprising, gives the truest picture.

◆ Good to know

Ranges are close to adult values by the teen years. Caffeine, energy drinks, anxiety and recent exercise can all push heart rate and blood pressure up for a while.

Measuring at this age

  • Repeat a surprising blood-pressure reading after five quiet minutes — first readings at this age are often high from nerves.
  • Ask about caffeine and energy drinks before judging a fast resting heart rate.
  • Resting heart rate is most meaningful first thing in the morning, before getting up.

Fever at this age

A temperature of 100.4°F (38.0°C) or higher is a fever. Thresholds, measuring methods and warning signs by age are covered in the fever guide — and any fever in a baby under 3 months old needs medical care the same day.

Please note: This page is patient education, not medical advice. Normal ranges are guides for a person who is awake, resting and measured correctly — a single reading outside the range is not a diagnosis. Abnormal readings in someone who is unwell, breathing with difficulty, unusually drowsy or simply worrying you warrant medical care — seek it promptly rather than re-checking at home.
