Surprising Signs Your Immunity Needs a Boost

[BABY1]

Tweet1. You have a sweet tooth.

<SMALL>Eating too much sugar doesn't just pack on pounds … </SMALL>
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 water.

<SMALL>There's a reason moms and doctors always push fluids on you when you're sick.</SMALL>
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 a lot of weight to lose.

<SMALL>You know excess weight is unhealthy for your heart, brain and other organs. But it's also bad for your immune system. </SMALL>
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 water from a well.

<SMALL>Surprisingly, the cleanliness of your drinking water can play a role in whether or not you get sick. </SMALL>
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 Sahara desert-dry.

<SMALL>As uncomfortable as it may be, a runny nose is actually a good defense against colds and the flu.</SMALL>
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 always seriously stressed out.

<SMALL>It's no coincidence that you tend to catch a cold after a big work deadline. </SMALL>
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.

7. You're always nursing a cold.

<SMALL>This means your immune system isn't operating at top speed. </SMALL>
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 foods can help.

TweetI use Goji juice it if full of antioxidants and helps to boost the immune system and help you stay younger looking. Ppl from Tibet and Asia use it alot, but the natural kind, but to me it just doesnt taste good, so i opt for the juice. You can get it at most healthfood stores. the one i take is called Goji Splash and i only take a serving once a day. It will last a good month. If you notice Asians and Tibetans generally live longer lives and look much younger than their ages.
