# Habits That Can Lead to a Cold You Might Not Know About

The main culprit is sleep deprivation. When you don't get enough sleep, your immune system tanks, and your body becomes defenseless against viruses. A lot of people know this in theory, but they keep going to bed at 3 a.m., scrolling through their phone feed. Stress works in a similar way - constant tension literally suppresses your body's defenses. If you're frequently anxious or living in a constant rush, your chances of catching a cold go up.

There are some more hidden things too. For instance, a sedentary lifestyle slows down your circulation, and your immune system works worse. Taking a hot shower right before going out into the cold isn't helping, even though it might feel like a lifesaver. The temperature shift stresses your body out. People also often forget about air humidity in their rooms: when the heating or air conditioning is on, your mucous membranes dry out and become permeable to viruses.

The habit of ignoring the first symptoms is sneaky too. You feel a scratchy throat or slight malaise - lots of people keep working and taking the metro instead of resting. And yeah, frequently using antibacterial gel kills the good microflora that helps protect you from infections. Regular soap and water is way more effective.

One of the sneakiest habits is ignoring wet feet and damp clothes. It seems like an old wives' tale, but sudden cooling of your extremities actually does constrict blood vessels and reduces blood flow to the mucous membranes in your nose and throat - that's exactly where viruses settle. I've noticed that after a walk in soggy shoes or wet socks, people really do get sick more often. The same thing happens if you've been sitting on a cold surface for a long time or went out sweating into the wind.

There's another thing people talk about less: mouth breathing. When you breathe through your nose, the air warms up and gets moisturized, and the nasal mucosa catches most of the viruses and bacteria. With mouth breathing, all of that goes straight into your throat and trachea. This is especially relevant for people who snore, sleep with their mouths open, or breathe through their mouth during exercise.

Plus there's the frequent habit of touching your face with your hands - touching your eyes, nose, mouth - it's a direct way to transfer a virus from a surface straight to your mucous membranes. And often we don't even notice we're doing it, we do it automatically. In itself this won't cause a cold, but if someone around you is sick, the risk of catching it shoots up dramatically.
