Daylight Savings Time and Risk of Heart Attack?
Daylight -saving time this year begins March 11, and while we all might look forward to another hour of sunshine a University of Alabama at Birmingham expert says the time is not necessarily good for your health.
"The Monday and Tuesday after moving the clocks ahead one hour in March is associated with 10% increase in the risk of having a heart attack", says UAB Associate Professor Martin Young, Ph.D.,in the Division of Cardiovascular Disease."The opposite is true when falling back in October.This risk decreases by about 10%"
The Sunday morning of the time change doesn't require an abrupt scheduale change, but, Young says,heart-attack risk peaks on Monday when most people rise earlier to go to work.
" Exactly why this happens is not known but there are several theories,"Young says."Sleep deprivation, the body's circadian clock and immune responses all can come into play when considering reasons that changing the time by an hour can be detrimental to someone's health".
"Wake up 30 minutes earlier on Saturday and Sunday than you need to in preparation for the early start on Monday.Eat a decent-sized breakfast , Go outside in the sunlight in the early morning, Exercise in the mornings over weekend( as long as you do not have pre-existing heart disease).
Doing all of this will help reset both the central ,or master clock in the brain that reacts in light/dark cycles,and the peripheral clocks."
Enjoy your Sunday!
