Blood Pressure Rest TimerFree 5-minute rest timer before blood pressure measurement. Clinical guidelines require 5 minutes of quiet rest for accurate readings. Start instantly.Frequently asked questionsWhy do you need to rest 5 minutes before taking blood pressure?Physical activity, stress, and conversation all temporarily raise blood pressure. The American Heart Association recommends 5 minutes of quiet rest to allow blood pressure to return to its resting baseline. Readings taken without this rest period can be 10-20 mmHg higher than true resting values.What position should I be in during the rest period?Sit in a chair with back support, feet flat on the floor (not crossed), and your arm supported at heart level. Do not lie down — this gives a different reading than the seated position used for clinical reference values.Does caffeine affect the rest period?Yes — caffeine can temporarily raise blood pressure. Avoid coffee, tea, and energy drinks for 30 minutes before measuring. The 5-minute rest period does not neutralise recent caffeine intake.Should I take multiple readings?Yes — the AHA recommends 2-3 readings taken 1 minute apart and averaging them. Take the first reading, wait 1 minute, then take a second. If they differ by more than 5 mmHg, take a third reading.How often should I check my blood pressure at home?For monitoring diagnosed hypertension: morning and evening, 7 days before each doctor visit. For general wellness checks: monthly. Always measure at the same time of day for comparable results.
