How strong is your immune system?
Some people seem to survive cold and flu season with nary a sniffle.
And yet plenty others seem to catch cold after cold; sidelined with a perpetually stuffed-up nose and hacking cough that lasts all winter long. So what’s different between these two groups? Research shows your cold and flu vulnerability may come down to a few important–and unexpected–habits, like how much sugar you eat or how dry your nose is.
Assess your risk with these 7 signs of impaired immunity, and learn what you can do to stay healthy.
You have a sweet tooth
Eating too much sugar doesn’t just pack on pounds…
A study published in the American Journal of Clinical Nutrition found that eating 100 g of sugar (think three cans of soda) significantly hampered the ability of white blood cells to kill bacteria for up to 5 hours afterward.
You don’t drink enough
There’s a reason moms and doctors always push fluids on you when you’re sick.
Your body needs plenty of water to flush out toxins–and yes, coffee and tea are acceptable sources. How much fluid you should drink daily varies from person to person. You’re drinking the right amount if your urine is pale yellow.
You’ve got weight to lose

You drink well water
Surprisingly, the cleanliness of your drinking water can play a role in whether or not you get sick.
As many as 25 million Americans drink well water that contains more than the safe levels of arsenic determined by the EPA. Arsenic has been linked to several different cancers, and affects the immune response to swine flu as well. When researchers from Dartmouth Medical School inoculated two groups of mice with the H1N1 virus, the group that had spent 5 weeks drinking arsenic-tainted water developed suppressed immune systems, and many died. The mice that didn’t drink the water got the flu but recovered completely.
If your well water tests high, consider switching to bottled water or investing in a remediation system that will remove the arsenic.

You’re seriously stressed
It’s no coincidence that you tend to catch a cold after a big work deadline.
According to a report by the American Psychological Association, long-term stress weakens the responses of your immune system. In addition, “if you become stressed while you have the flu, your symptoms can get worse,” says Philip Tierno, PhD, director of clinical microbiology and immunology at New York University and author of The Secret Life of Germs: What They Are, Why We Need Them, and How We Can Protect Ourselves Against Them.
You always have a cold
This means your immune system isn’t operating at top speed.
The average adult picks up one to three colds each season that typically last 3 or 4 days. If you get more, your resistance might be low. Getting more sleep, regular exercise and rounding out your diet to get lots of healthy veggies and these immunity-boosting foods can help.
