why cold occurs

Colds are primarily caused by viruses, with the most common culprit being the rhinovirus. This pesky virus is incredibly good at spreading, especially during the colder months, but not because the cold weather directly makes you sick. The drop in temperature is often accompanied by the fact that people spend more time indoors, in close proximity to others, and this can facilitate the transmission of viruses from person to person. Your immune system might be vulnerable to these viruses if you’re experiencing stress, fatigue, or if you’re not getting enough sleep. All these factors can potentially increase one’s susceptibilty to infections, even if you maintain a healthy diet and exercise regularly. The notion that being exposed to cold weather weakens your immune system so you catch a cold isn’t exactly true. It’s more about the environmental changes and behavior shifts that tend to coincide with colder weather. Indoor heating can dry out the mucous membranes in your nose, making it easier for viruses to take hold. Additionally, changes in humidity outdoors can also have an effect, as low humidity levels can assist in virus survival. As for prevention, frequent hand washing is your first line of defense — viruses can live on surfaces for several hours, and touching your face after coming into contact with contaminated objects is a common way these invaders enter your body. Try to maintain a balanced diet rich in fruits and vegetables, get adequate rest, and if you feel these symptoms coming on repeatedly, consider making sure your environment maintains an optimal humidity level. However, if your cold symptoms are frequent and seem too intense or prolonged, it’s a good idea to consult a healthcare professional for further evaluation, as there might be underlying issues contributing to your recurrent symptoms beyond just weather changes.
