Cold season is upon us, and as temperatures drop, so does our resistance to pesky colds. But one doctor is sharing some unusual, science-backed methods to help you stay healthy that might surprise you. Dr. Jessica Kiss, known to many as “Dr. Mom,” has highlighted a few unconventional tips that, while unexpected, could make all the difference in preventing colds this season.

First up: tongue cleaning. While brushing and flossing are routine for most, tongue cleaning is often overlooked. Yet, studies have shown that bacteria on the tongue can impact overall immunity. Dr. Kiss explains that removing bacteria buildup not only improves oral health but may also reduce cold susceptibility by keeping the immune system in check. And, let’s face it, it’s a lot easier to add this to our routine than to battle a cold later on.

Next, Dr. Kiss recommends adding green tea to your daily diet. Known for its antioxidants, green tea boosts the immune system, helping to ward off viruses before they take hold. Just one cup a day can make a noticeable difference. While these benefits aren’t exactly new, Dr. Kiss reminds us that green tea’s role in cold prevention is often underestimated.

The third tip? Sleep with a humidifier. Dry air, especially in colder months, can dry out the nasal passages and make it easier for viruses to enter the body. A humidifier maintains optimal moisture levels, supporting respiratory health and reducing the chances of waking up with a scratchy throat. Simple, right? Yet so many skip this affordable step, opting instead to reach for tissues and over-the-counter meds once symptoms appear.

Rounding out her list are regular hand-washing and a steady intake of Vitamin D. While these might seem like familiar advice, the importance of these measures can’t be overstated. Dr. Kiss points out that Vitamin D not only strengthens immunity but also improves mood, which, in the dark winter months, is crucial for overall health.

With these straightforward, unconventional methods, Dr. Kiss offers alternatives to the typical cold-prevention advice. The best part? They’re all affordable, easy to incorporate, and backed by science. This winter, as you stock up on essentials, consider adding these simple steps to your daily routine. Sometimes, it’s the little things that make the biggest difference.
