Physiological sinus tachycardia is usually preventable and care should be taken to eliminate triggers. If excessive caffeine consumption or smoking is causing sinus tachycardia, these habits can be stopped.
It is important to note that patients with co-morbid heart conditions are at a higher risk of tachycardia, so measures to maintain a healthy heart may be helpful in preventing sinus tachycardia: such as a balanced and sensible diet, consistent exercise, and weight loss in overweight or obese individuals.
