Activity, stress, fever and caffeine affect heart rate; accompanying symptoms matter.
A temporary increase during exercise or anxiety can be normal. Recurrent or prolonged palpitations, a very irregular pulse, or palpitations with chest pain, fainting, severe weakness or breathlessness require assessment. A smartwatch is a screening tool, not a definitive diagnosis.
Medical principle
High blood pressure and diabetes may remain symptomless for a long time. Correct measurements and periodic tests in people at risk are more reliable than waiting for symptoms. Lifestyle changes complement treatment and are not a reason to stop medicines yourself.
Practical steps that may help
- Record blood pressure in standard conditions on different days and show the average to your doctor.
- Regular activity, less salt, enough sleep, stopping tobacco and a suitable weight help reduce cardiovascular risk.
- Do not change blood pressure or diabetes medicines because of one good or bad reading without advice.
When should you seek medical care?
Chest pressure or pain, breathlessness, fainting, sudden one-sided weakness or numbness, speech problems or reduced awareness are emergencies.
