Multi vitamins along with plenty of rest and healthy food and exercise are all essential in recovering or preventing these conditions. Until now hand washing seems to the best method of avoiding and treating a person with common colds and coughs. And no matter what we do to treat our colds there is no more perfect cure than mental peace and a stress free life which is in our hands to make. Personally, I would just get into bed, cover myself with lots of blankets, switch on my soft music with lots of chicken broth with lots and lots of black pepper and a nice book in hand when I have severe cold and cough. How could I not chill in bed as long as I don't have to go to work that day? Next time when you get a cold or cough that you cannot seem to get rid of easily, try my way--just chill at home and take it easy because, OUR LIFE MATTERS.
