As the days get colder, a reminder for all of you who are at higher risk of heart disease (which is just about anyone over the age of 40, I think) that when the weather turns cold, the number of heart attacks goes up.

In fact, a few months ago, a study published in the British Medical Journal found that when the temperature in the UK drops by one degree Celcius, the number of heart attacks goes up by about 200.

There are a number of potential reasons starting of course with the fact that people become more sedentary when winter sets in, that people who should know better still go out and clean snow off their driveways after a snowfall (well, if you’re like me, you better clean your walkway if you want to keep peace at home), and probably because cold temperatures have a biological effect on the body, perhaps by making the blood more “Sticky” and hence leading to more clots, such as those that occur in some heart attacks and strokes.

So, when the temperature goes down, remember to try to keep warm, to avoid overdoing it when working outside, to keep working on reducing your other risk factors for a heart attack, and if you can afford it, of course, to spend as much time as you can in Hawaii.
