While it is summer for all of you in the northern hemisphere, it is winter down under which means cold and flu season has come around again. Although for those of us with kids in daycare and school it seems that cold and flu season lasts all year-round! Here are some helpful hints for keeping the whole family healthy in winter and all year long.

Psychological stress is associated with a greater risk of depression, heart disease and infectious diseases.[i] Take time out - exercise, garden, meditate, whatever it is that helps you to relax.
What would one of my articles be if I didn’t mention exercise? Exercise is important for everyone. To keep your immune system at its best you want at least a brisk 30-minute walk each day. If you are an avid athlete you also need to take care, as very high intensity exercise can put a strain on your immune system.[ii]
Always wash your hands before eating. There was a 75% reduction in flu-like symptoms when a test group wore masks and washed their hands.[iii] It can really be just that easy.
Our bodies are composed of 70% water. Proper hydration is important for the optimum functioning of all your body systems. Increase your water intake slowly getting up to 2L per day.
Hot-Cold showers are an excellent way of improving your immune system, increasing circulation and elevating energy levels. After finishing your regular shower routine, do 20 seconds of cold and 1 minute of hot. Alternate 2-3 times, ending with cold. The increase in circulation will also help decrease sensitivity to the cold.
There are several supplements you can take to help boost your immune system. Daily zinc supplementation has been shown to shorten the duration and severity of the common cold, reduce the incidence of acute lower respiratory tract infections in preschool children by 45% and reduce the incidence of pneumonia by 41%.[iv]
Vitamin C is found in high concentrations in immune cells and is quickly consumed during an infection. It is a natural antihistamine and has been found to reduce the severity and duration of the common cold and upper respiratory tract infections.
More than 80% of the body’s immune system is in the digestive tract.[v] A lack of good bacteria in the digestive tract can cause a reduction in the immune system allowing increased infections. Take a good quality probiotic to prevent bad bacteria from taking hold.
Vitamin D has a direct effect on the immune system. Vitamin D stimulates the production of natural antibiotic proteins thus killing more bacteria. Insufficient levels are related to a deficiency in our immune system to protect us against infections.
These are just a few suggestions. For personalized advice, contact your local naturopath. Let's stay healthy this winter!
