FLUCTUATING BLOOD PRESSURE.

Hello Doctor, My husband is 40 years old and works in the IT sector, which involves long hours of sitting and screen time. His blood pressure readings usually range between 128/80 to 140/90, with some readings around 130/86. He is not currently taking any medication for blood pressure or any other health condition. I’m planning to monitor his BP regularly at home and maintain a log. Could you please advise: What is the best time of day to take BP readings? Should we take the reading right after waking up, or before/after exercise, pranayama, or walking? Is it useful to check in the evenings, before or after dinner? For how many days should we track the readings before consulting a cardiologist? His pulse rate usually stays between 72–76 bpm. I just want to ensure we’re tracking correctly and taking the right steps before seeing a specialist. Kindly guide us. Thank you.
