A review highlights how our body’s internal clock, called the circadian rhythm, affects heart health. This 24-hour cycle helps regulate things like blood pressure, heart rate, and metabolism, all of which change naturally throughout the day. But when this rhythm gets thrown off, due to shift work, irregular sleep schedules, or even social habits, it can increase the risk of heart problems.
Research shows that disruptions in our circadian rhythm are linked to higher rates of high blood pressure, irregular heartbeats, and heart attacks. Factors like obesity, aging, and sleep disorders can also mess with this internal clock, making people more prone to heart issues.
One interesting area of research is chronotherapy, which looks at whether medical treatments could be more effective if timed to fit our body’s natural rhythms. As we learn more about how the circadian clock works, doctors might be able to use this knowledge to better prevent and treat heart disease, especially for people whose schedules don’t line up with their body’s internal timing.
