The Monday Morning Heart Attack

Monday mornings have always been synonymous with the drudgery of
starting another work week. Now there appears to be yet another reason
to dread Monday mornings. More people have heart attacks on Mondays
than any other day of the week. At first it might sound farfetched, but
a 10-year Scottish study found that about 20% more people die from
heart attacks on Mondays than on other days. Scientists have long seen
a possible link between binge drinking, which is more likely to occur
on the weekends, and sudden fatal heart attacks. The researchers
theorize that weekend drinking and socializing, coupled with the stress
of returning to work, is too much for some people to handle.
Keeps this in mind if you ever find yourself saying that you "live for
the weekend." While that may be true, what about the other five days of
the week? If you look at work as a horrible prison, you are going to
spend the majority of your days feeling miserable. Spending your time
anticipating the weekend, feeling free for only two days, and then
feeling panic at the thought of returning to work is a never-ending
cycle that will not only make your life unfulfilling, but may also lead
to heart attacks. People who are generally happy and calm have fewer
heart attacks then unhappy, stressed individuals.

While a person's family medical history greatly affects their chances
of having a heart attack, certain situations can also trigger a serious
attack. Large meals, strenuous physical exertion, and distress are some
of the extenuating circumstances. Think about the big meals you eat and
yard work you are more likely to perform over the weekend and it all
starts to add up.

Why not Monday afternoon or Monday evenings? Your body goes through
some stressful changes upon wakening. Your heart rate and blood
pressure shoot up. Even your blood is more prone to clotting in the
morning, when the blood platelets are at their stickiest. Stress
hormones will also be released, especially on mornings when you are
headed back to work. If you're running a few minutes behind or fighting
traffic, these hormones go into high gear. The main stress hormone
serotonin narrows blood vessels, forcing your heart to work harder. Of
course, this terrible phenomenon isn't limited to just Monday mornings.
Some studies have found that sudden cardiac arrest increases 60% among
stressed soccer fans on World Cup game days.
