Because so many viruses cause them, there isn't a vaccine that can protect against catching colds. But to help prevent them, kids should:
Try to steer clear of anyone who smokes or who has a cold. Virus particles can travel up to 12 feet (3.7 meters) through the air when someone with a cold coughs or sneezes, and even secondhand smoke can make your child more likely to get sick.
Wash their hands thoroughly and frequently, especially after blowing their noses.
Cover their noses and mouths when coughing or sneezing.
Do not use the same towels or eating utensils as someone who has a cold. They also shouldn't drink from the same glass, can, or bottle as anyone else - you never know who might be about to come down with a cold and is already spreading the virus.
Do not pick up other people's used tissues
Do :
Keep soles clean
Wear soft, cushioned, comfortable shoes or slippers
Wear socks to prevent friction
Apply oil, if there is dryness
Take rich sources of vitamins - fruits, dates, leafy vegetables etc.
Should not do:
Walking bare foot
Tight shoes
Standing for a long time in water
Contact of bleaching powder or any other chemical
Using strong chemical soaps
