Why do I constantly have a cold?

Possible Reasons for Frequent Colds

Some common factors might include insufficient hand hygiene, sharing food and drinks, not using tissues properly, and failing to dispose of them. Your surroundings can also play a role; for instance, dry air, exposure to tobacco smoke, and touching surfaces that may harbor germs. Additionally, not getting enough sleep can be detrimental. Adequate rest is essential, as it promotes the release of proteins and antibodies that are vital for combating inflammation and fighting off infections.
