Adherence

Individuals significantly underestimate their cardiovascular risk and their level of physical activity, demonstrating a disconnect between perceived and actual metrics.

Do not rely on your gut feeling to judge your health risk or activity level. You are likely underestimating your risk and overestimating your activity. Use objective tools like smartphone sensors or medical checkups to get a true picture of your cardiovascular health.
