Please help i catch cold very often.

Colds: try taking vitamin C on a daily basis this may help you from getting colds all the time

Cold: An adult can expect 2-4 colds a year, and a young child about 3-8 colds a year. Many different viruses can cause a cold. This is why colds come back (recur), and immunisation against colds is not possible. Good diet, lots of Vitamin C and regular exercise can help to boost immune system and can be tried. http://patient.info/health/common-cold-and-other-upper-respiratory-tract-infections

General health?: There are medical reasons like being immunosupressed from diseases or medications. The most common reason is going to be overall lifestyle: Are you overweight? smoke? exercise? diet? stress? sleep? All these and more will play a part in making you more suseptible to catching colds.
