Night owls may have a higher risk of suffering from heart disease and type 2 diabetes than early risers.

In the first ever international review of studies analyzing whether being an early riser or a night owl can influence your health, researchers have uncovered a growing body of evidence indicating an increased risk of ill health in people with an evening preference as they have more erratic eating patterns and consume more unhealthy foods.

Does performing/undergoing surgery in the afternoon reduce the risks?

A new study suggests patients undergoing open heart surgery in the afternoon have a lower risk of potentially fatal complications than those undergoing operations in the morning. The study found that events including heart attacks and heart failure were less common among those who had undergone a valve replacement operation in the afternoon. The finding appears to be linked to the ability of the heart tissue to recover after being starved of blood supply during surgery – an effect the researchers say is influenced by the cells’ biological or “circadian” clock.
