Doctors often ask: "Is this new for you?" Knowing your own normal makes that question easy to answer — and helps you notice changes early. You don't need special equipment for most of it.
Your baselines
- Resting pulse: count your heartbeats for 30 seconds at the wrist while sitting calmly, and double it. For most adults it is between 60 and 100 beats a minute; people who exercise regularly often have lower rates.
- Blood pressure: a reading below 120/80 mmHg is considered normal. Repeated readings of 140/90 or higher mean high blood pressure, which often has no symptoms — so measure it now and then, at a pharmacy or health centre.
- Weight and BMI: body mass index between 18.5 and 24.9 is the healthy range for most adults. It is a rough guide: it doesn't separate muscle from fat.
- Temperature: normal body temperature is around 36.5–37.5 °C; 38 °C or more is a fever.
Everyday signals
- Energy: tiredness after a poor night is normal; tiredness every day for weeks is worth mentioning to a doctor.
- Sleep, appetite and mood: steady patterns are a good sign; sudden lasting changes are worth attention.
- Bowel and bladder habits: changes that last more than a few weeks should be checked.
- Skin: watch moles that change in size, shape or colour, and sores that don't heal.
Keep a simple record
Write down your blood pressure, weight, test results and medicines, with dates. A short record helps you and your doctor see trends instead of single numbers.
Regular check-ups
Many health problems are easier to treat when found early. Ask your doctor or local health centre which check-ups suit your age, sex and family history.
Tools for this
Home measurements are useful for noticing change but don't replace a medical examination. If a reading or symptom worries you, ask a doctor. This guide is general information, not medical advice — see our safety note.
