Daylight saving time officially begins at 2 am this Sunday, March 8th. Although it may be only a slight annoyance to reset clocks or appliances, that one hour change can wreak havoc for days as far as your body is concerned.
As a nurse I have seen on the job accidents happen more frequently, productivity decline, and have read the research that shows an increase heart attacks when we lose that one hour of sleep that happens when we spring forward.
Circadian rhythm is the predictable biological and behavioral changes that follow a roughly 24-hour cycle-our master clock, basically. Even with just that one hour shift in that rhythm we feel and function differently. That difference is in part because our hormones are released differently and those hormones impact our appetite, how alert we are and how much inflammation is present in our bodies. Such changes can make an existing medical condition, such as cardiac disease worse.
