Immune function is really a combination of many body systems. Here are three simple things you can do to help make sure your immune system is in good shape:

Get 8 or more hours of sleep nightly. Your immune system does most of its house-cleaning at night. This is when your body kills abnormal (cancerous) cells, and does most of its work to beat viruses and bacteria. The immune system doesn't really ramp up to its full capacity until you've been asleep at least 5 hours!

Don't eat sugar. This means the refined white stuff which is a drug! White blood cell (immune cell) function is significantly impaired for about 4 hours following sugar consumption. Seriously!

Exercise outdoors. This goes for adults and kids. Get your Vitamin D naturally - from the sun! Most people tested in this office are deficient in Vitamin D due to indoor lifestyles. Fresh air and moving around promote natural detoxification and anti-depressant mechanisms in the body.
