Heart Rate and Blood Pressure
Heart Rate and Blood Pressure varies by age.
The NHS recommendations are generally wrong as they do not include age.
# Blood Pressure
There are many different results but in general the blood pressure increases by age. Below is from [link](https://www.myhsn.co.uk/top-tip/what-is-normal-blood-pressure-by-age-and-gender/):

- Blood pressure **increases with age**, and it is normal for arteries to become stiffer as people get older
- Normal BP goes up with age and is generally **higher in men**. When women hit the menopause BP starts to align with men (as do its risks)
- Hence, for people over 75 years, the ideal blood pressure is **under 150/90 mmHg** – as more BP is needed to keep the brain supplied with blood
- The **pulse pressure** – i.e. difference between the systolic (upper number) and diastolic (lower number) – also rises through life. It can be 40 mmHg at 20 years, and 70 mmHg at 80 years
- A blood pressure reading of **180/120 mm Hg** or higher is considered a hypertensive crisis and requires rapid **medical attention** (today).
Average.
| **Blood pressure** | **Systolic (mmHg)** | **Diastolic (mmHg)** |
| -------------- | --------------- | ---------------- |
| Low | <90 | <60 |
| Normal | 130 | 80 |
| Normal to high | 131-139 | 81-89 |
| High | >140 | >90 |
**Note 1.** These numbers are ‘too neat’ to be true. But they are about right
**Note 2.** As BP also changes minute-to-minute in any individual person, and is affected by time of day (circadian rhythm), it is important not to react to one reading. It’s the pattern that matters.

# Heart Rate
