It's winter and as you have probably noticed, germs are everywhere — runny noses, sore throats, nothing quite like the common cold to make you feel miserable.

But experts believe that there is no link between cold weather and catching colds. So why are we particularly vulnerable this season?

Internal Medicine expert, Dr Meenakshi Jain of Max Hospital says, "One reason could be because people are likely to stay indoors, so the virus can spread easily. Also the virus thrives in humidity."

The common cold is a viral infection that can be caused by any of up to 250 strains of virus, the most common group of which are the rhinoviruses that hit the nose.

They are responsible for anywhere between a third and half of all common colds.

"They are transmitted through the nose and respiratory passages, by touch, and by contact with airborne particles that are created by sneezing or coughing," says Dr Jain.

There is no cure for the common cold and antibiotics are of no help. However, there are some precautions which can help:

Wash your hands regularly, so that germs get killed.

Don't touch your eyes, nose and mouth, which can limit your chances of infection.

Don't share drinking glasses or utensils with anyone as this will prevent the spread of the virus.

Drink lots of fluids to avoid dehydration.

Make sure to eat enough fruits to boost your immune system.

Get enough sleep and you'll certainly become stronger.
