why do we get cold

Colds, or the common cold, are primarily caused by viruses, especially the rhinoviruses. When you get that scratchy throat and runny nose, it’s because one of these viruses has managed to penetrate your body’s defenses, usually through the respiratory tract. Cold weather itself doesn’t directly cause colds; rather, it’s the environment during colder months that facilitates the spread of these viruses. When the temperature drops, people tend to stay indoors more often, increasing close contact with others, which helps viruses spread. Also, cold and dry air can dry out your nasal passages, reducing their ability to trap and expel viruses efficiently.

As for old wives’ tales about wet hair or being inadequately dressed, these don’t really hold up scientifically for causing colds. However, being in the cold may indirectly affect your body’s immunity by stressing the body a bit, but the viruses are the main culprits. To prevent future colds, focus on good hygiene: wash your hands often, avoid close contact with sick individuals, and avoid touching your face unnecessarily. Keeping your immune system strong by getting plenty of rest, eating a balanced diet, and managing stress can also be helpful. During peak cold seasons, consider increasing your intake of vitamin C and zinc, as there’s some evidence they might help shorten colds if they do happen. If you feel symptoms coming on, like a sore throat or stuffy nose, rest up and stay hydrated to give your body the best chance to fight back quickly. If your condition worsens or doesn’t improve, it’s prudent to seek medical attention, since some symptoms might actually indicate something more serious than a cold.
