Immune System

Some people skate through cold and flu season without even a sniffle.  While others seem to pick up any germ that comes near them.  So how do some people get sick and some do not?  Experts agree that it comes down to your immune system.  Here are seven signs that you may have a weak immune system which could make you more susceptible to sickness. 

1. 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.
2. 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.
3. You’ve got weight to lose.  You know excess weight is unhealthy for your heart, brain and other organs.  But it's also bad for your immune system.  In fact, those who become most seriously ill with swine flu tend to share the same characteristic: a body mass index over 40, meaning they are morbidly obese. Excess weight can cause hormonal imbalances and inflammation that impairs the immune system's ability to fight infection.
4. 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.
5. Your nose is dry.  As uncomfortable as it may be, a runny nose is actually a good defense against colds and the flu.  Sounds gross, but mucus traps viruses and clears them from the body. If your nasal passages are too dry, germ invaders have an easier time. If the dryness is a temporary problem, irrigate your nasal passages with a squeeze bottle or neti pot of saline solution. A humidifier can also help. If dryness is chronic, see your doctor to determine the underlying cause.
6. 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 .
7. 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.
