condition. It also depends on the environment and your state of mind at the time of 

measurement. In general, your blood pressure is lower when you are asleep and higher when 

you are active. Your blood pressure may be higher when recorded at a hospital or a clinic and 

may be lower when measured in the relaxing comfort of your home. Due to these variations, we 

recommend that you record your blood pressure regularly at home as well as at your doctor’s 

clinic.

•  Try to record your blood pressure regularly at the same time of the day and under the same

conditions. This will help your physician detect any extreme variations in your blood pressure 

and thus treat you accordingly.

cardiovascular risks (heart failure, stroke, angina) associated with “morning hypertension”.

There is a typical rise in blood pressure during the physiological changes from sleep to arising 

for the day.

•  The ideal times to measure your blood pressure is in the morning and at least 2 hours after

dinner. Measure just after you wake up, before breakfast and any physical activity, and in the 

absence of the urge to urinate. If this is not possible, try to take the measurements later in the 

morning, before you start any physical activity. Relax for a few minutes before you record your 

blood pressure.

•  Your blood pressure increases or decreases under the following circumstances:

Blood pressure is higher than normal:

- When you are excited, nervous, or tense

- While taking a bath

- During and after exercise or strenuous physical activity

- When it is cold

- Within two hours after meals
