Night Owl or an Early Bird?

How does your sleep pattern put your cardiovascular system at risk?

Evening types are 79% more likely to have poor overall heart disease compared to morning types. Research indicates night owls often have poorer metabolic function, lower fat burning, and a 16% higher risk of stroke or heart attack.

Studies from Rutgers University published in Experimental Physiology show that night owls have a reduced ability to use fat for energy, causing fat to build up, increasing risks for Type II diabetes and cardiovascular disease.

A 2026 study in the Journal of the American Heart Association found that people whose internal body clock doesn't match the natural light cycle (e.g., staying up late) have poorer diets, sleep less, smoke more, and exercise less, all of which are strong risk factors for heart disease.

Why Early Birds Often Have Better Health:

Early birds tend to use fat as an energy source more efficiently. They often have better aerobic fitness and are more active during the day. Early birds are associated with better cognitive function and lower depression rates.
