Some studies show heart attacks happen more often in winter than in warmer months.
There are common theories to this, including more stress. Think about it…the holidays can be very stressful. Also, strenuous activities can lead to more heart attacks. Shoveling snow is a big culprit.
But one theory is a bit unique. It turns out that cholesterol might be a factor in it as well.
In a recent study, patients' cholesterol levels were about 8 percent higher, on average, in colder weather than those of patients whose blood was tested during the summer.
Just check out the science behind the theory… Less sun exposure in winter may partially explain the variation. See vitamin D is known to improve the ratio of “good” and “bad” cholesterol levels.
Also, people eat more and exercise less in colder weather.
