Nothing
short of sealing yourself up in a bubble can keep you germ-free. But you can
make yourself a less likely target for infectious diseases — and better your
chances of making a complete recovery when you do fall sick with anything from
a common cold to strep throat, or even hepatitis. How? By building and
maintaining a robust immune system. Here’s your to-do list:
Stop smoking! Of all the ways to suppress
your immune system, smoking tops the list. One example: Smokers get the flu
more often — and are more likely to die from it — than nonsmokers are.
Toss the toxins. Limit your exposure to
polychlorinated biphenyls (PCBs), mercury, chemical pesticides, and secondhand
smoke. They can severely compromise your immune system, and may contribute to
life-threatening autoimmune diseases.
Sleep tight. Too little or poor-quality
sleep impairs overall immune system function and reduces the number of
germ-killing cells in your body.
De-stress. Chronic stress causes a
measurable downturn in your system’s ability to fight off or recover from
diseases.
Get happy. Even mild sadness can
weaken your immune system, and the more negative and pessimistic you are, the
more likely you are to get sick. Cheerful, optimistic souls have an army of
battle-ready, infection-fighting T cells in their bodies.
Get a move on. A recent study compared
people who took almost-daily brisk walks to folks who were inactive. The non-walkers
took twice as many sick days as their strolling counterparts.
Pal around. The more human connections
you have, and the more you get out and about, the better you can fight off
illnesses.
Eat well. Good nutrition strengthens
your immune system. Poor food choices are major immunity busters.
Yuk it up. Laughter decreases stress
hormones and raises your supply of immune-boosting hormones and endorphins.
Limit antibiotics. While they are sometimes
necessary, they can suppress your immune system and make you more likely to
become sick again.
