How many colds per year is considered normal?
The Centers for Disease Control and Prevention estimates that the average adult has two to three colds per year, and children typically get more. Colds generally take about 7 to 10 days to get over and can easily spread from person to person through living in close quarters, sneezing without covering your mouth, and touching surfaces without washing your hands.
Why do I get sick so often?
Despite the ease with which cold viruses spread, some people seem to be immune while others are always sniffling. Your immune system is a complex mechanism, and several factors can either strengthen it or cause it to be compromised. If you’re wondering why you keep getting sick, there can be several things you can do to reduce how often you’re ill.
An immune system that isn’t functioning properly leads to frequent illnesses. Some disorders are genetic, and some are a result of viruses that compromise the immune system. There are different types of immune disorders. Sometimes people are born with a weak immune system, called primary immune deficiency. If you contract an illness that weakens your immune system, it’s called acquired immune deficiency.
