Blood pressure may also be affected by a sudden change in weather which may cause the body to react to abrupt changes in humidity, atmospheric pressure, wind and cloud cover in a similar manner as it does to cold, although these variations are more common in those aged 65+.
It is common to see some fluctuation in blood pressure pattern throughout the day as your blood pressure will continue to increase during the day to typically peak around midday, and later in the afternoon/evening your blood pressure will begin to drop again.
Having an abnormal blood pressure pattern such as being high during night/early morning can be an indicator of there being a health problem. Conditions associated with abnormal blood pressure patterns include: diabetes, obesity, obstructive sleep apnoea, thyroid problems, nervous system problems, cardiovascular disease, and poorly controlled high blood pressure.
Abnormal blood pressure patterns can also be influenced by risk factors such as anxiety, obesity, tobacco use, drug use, alcohol use, stress, working shift work, working night shift, and taking blood pressure medications that don’t last for 24 hours.
If you care concerned consult with your doctor who will be able to determine if you have an abnormal daily blood pressure pattern. A 24 hour blood pressure monitoring test may be recommended to help your doctor determine if you have an abnormal pattern. This testing involves using a device that will measure your blood pressure at regular intervals over 24 hours to provide your doctor a more accurate picture of your blood pressure changes over an average day and night which will be used to develop a plan of treatment, if needed, best suited to your needs.
