All the usual things for a strong immune system apply of course: healthy diet, reasonable amount of exercise and staying as relaxed as you can. But winter is a season in which you are at greatest risk of illness so it pays to take extra precautions.
Many viruses seem to like cool, damp conditions and our winter social habits help them as well. Cold and flu viruses are spread by droplet infection which means that millions of virus particles will be ejected from the nose and mouth of an infected person. We tend to congregate indoors a lot more in winter: parties and family get-togethers, usually with the windows shut and this simply allows the virus concentrations build up.
Our immunity is naturally lower in winter - those of us in northern climes anyway. Less sunshine means less vitamin D, an important contributor to the immune system. Some people find the constant gloom of winter very depressing and this will tend to have an adverse effect on immunity.
Boosting the Immune System
There are a number of ways of doing this. From what’s been said above a vitamin D supplement or increasing your intake of vitamin D containing foods is likely to be helpful
Some herbs have long been known to be beneficial in helping to fight infection. The most well known is probably Echinacea. This native plant of the United States is famous for its blood purifying properties.
One of the world’s best known herbs – garlic has an anti-infective action. It is also very good for improving the circulation.
There is some evidence that tincture of elderberry can provide much support for the immune system. Traditionally elderberries have been used to ward off winter colds.
Other things you can do in addition to taking herbs or supplements include taking plenty of exercise in the fresh air – even on cold days. Walking in green leafy areas is likely to be even more beneficial.
Get plenty of sleep and avoid too much stress; easier said than done of course but the more relaxed you can stay the healthier you will be.
Cold and Flu Remedies
If, despite your best efforts you do go down with a cold or flu, here are a few remedies that will help you to stay more comfortable.
- Ginger: a tea made from steeping ginger root slices in hot water, sweetened with honey if desired, will ease the throat and chest and will promote sweating.
- Raspberry: an infusion of raspberry leaves is good for sore throat.
- Rose: rose petals have long been used as a tea with honey to ease sore throat and headache.
- Essential oils: a steam inhalation of a few drops each of eucalyptus and lemon oils in hot water will help clear the nasal passages.
To make an infusion or tea add about 1ounce (25g) of fresh leaves or petals to about one pint (500mls) of boiling water, cover and allow to cool to lukewarm. Add honey if desired.
