Scroll down for video Different systems of the body – such as our circulatory system – follow circadian rhythms that are synchronised with a master clock in the brain. Its currently understood that shift workers– who tend to work inconsistent hours throughout the week– are more vulnerable to heart problems.This most likely assists the heart cope with increased needs during the day, when modifications in activity and cardiac output are much greater than at night, when we normally sleep.

Its already understood that shift workers– who tend to work inconsistent hours during the week– are more susceptible to heart issues.This likely helps the heart cope with increased demands throughout the day, when modifications in activity and cardiac output are much higher than at night, when we typically sleep.Whilst the circadian rhythm will change to a new routine (just like with jet lag), this takes several days and our health is more vulnerable throughout this time. Cardiovascular diseases are the number one cause of death worldwide, taking around 17.9 million lives each year.
