hi there, Common colds are due to the bacteria and viruses in the environment. People usually say that we catch cold but actually what we catch is the bacteria in the air. Through coughing and sneezing cold can be transfer from one person to another. Actually it is the hand to hand interaction great contributes for the spreading of colds. For easy inhalations you can use aromatherapy. Boil a cup of water then add drops of eucalyptus globulus. Put a towel on your forehead to avoid irritation better to close your eyes Inhale the scent of the essential in the steam. Do this for about five to ten minutes. hope it can help =)
