That Boost Your Immunity Interesting information on zinc, vitamin C, and the flu shot. Most experts agree, however, these remedies not only do not help but often make matters worse.
Colds tend to disappear without a trace, after running their course from stuffy head to drippy nose.
Unlike colds, flu comes on rapidly, with the telltale arrival of symptoms such as muscular aches and pains, chills and fevers, sore throats and dry coughs, headache, exhaustion and depression. More severe than colds, flu can cause death in the elderly and chronically ill, but typically, sufferers feel wiped out for a few days and tired for a few weeks. Though not the same illness, both colds and flu are caused by viruses. There are hundreds of distinct cold and flu viruses out there. Because science is unlikely to keep you free of colds and flu, your best defense is to boost your immune system so it is strong enough to keep bugs at bay.
