DFL said:Hi there,
I smoke about a pack a week and about 2 on weekends. I run
3 times a week and swim in between those days. What is the
affetc that this has on my heart?
If one gets a lot of exercise does it lessen or decrease
the effects of smoking?
Thanks!
Smoking constricts the arteries like a vise. An occasional
smoker feels this effect as pleasure, alas, since the
arteries have time between smokes to regain their
flexibility. A chain smoker foregoes this twisted form of
pleasure, since his arteries are permanently in a hardened
state and essentially he is puffing away to get a fix of
nicotine..
I wouldn't be surprised to find that heart attacks often
occur upon lighting up a cigarette when the arteries
suddenly constrict. (I wonder if a study has ever been done
about this ?) To assess the damage that smoking does, you
need to understand that the cardiovascular system works
because of an active heart, but also because active arteries
which adjust with flexibility to stresses in the system
thereby protecting the heart from overloads. It is this
protection that is greatly decreased because of the
stiffening effect from smoking.
A second item which I learned from my friendly cardiologist
is that exercise can be detrimental to the cardiovascular
system if it is too strenuous. That's why you should hew
working out to the pulse rate guide lines published in
exercise books. Non strenuous exercise is a must, however,
in that it keeps the arteries supple and able to protect
the heart.
