Heart Healthy:
The American Heart Association (AHA) has released a new scientific statement linking circadian rhythm the body’s internal 24-hour clock with heart health. Experts say that the timing of daily activities such as eating, sleeping, and exercising can have a big impact on heart function, metabolism, and overall wellbeing.
Our body’s circadian rhythm works like a built-in timer that regulates sleep, hunger, and energy levels. It resets every day through exposure to light. When this rhythm gets disrupted for example, due to irregular sleep, late-night eating, or long work hours it can lead to health problems like high blood pressure, obesity and diabetes.
According to Dr. Kristen Knutson, chair of the AHA’s writing group, maintaining a regular schedule helps the heart perform better. “We should align our lifestyle with our internal clock for better heart health,” she says.
Experts suggest eating breakfast soon after waking up and avoiding heavy meals late at night. Having dinner 3–4 hours before bedtime gives the body time to digest properly and supports metabolism. Research also shows that people who eat breakfast before 8 a.m. have a lower risk of developing Type 2 diabetes.
Most adults should sleep for about eight hours during their “biological night.” Going to bed between 10 p.m. and midnight works best for most people. Consistent sleep and wake times even on weekends are important to prevent circadian disruption.
Experts recommend exercising during your “biological daytime.” Morning or afternoon workouts are best, but avoid exercising late at night, as it can affect sleep quality.
Morning sunlight helps synchronize your body clock. At night, avoid screens and bright lights before bed to support natural sleep cycles.
By keeping a steady schedule for sleep, meals, and exercise, you can support your heart and overall health. As Dr. Knutson says, “Your body clock is powerful take care of it, and it will take care of your heart.”
