• Breathing through the nose is a common practice in yoga, thanks to its many benefits.

• Physicians also recommend breathing through the nose, as it provides a natural filter.

• Breathing through the mouth can lead to poor oral health and bad breath.

Dr. Brian Lee of Scottsdale Sinus and Allergy Center says breathing through your nose is beneficial in a variety of ways, so much so that people who don't have regular sinus trouble might not realize the benefits.

"I think most people who don't have issues with their nose or sinuses have no idea," Lee told the Grand Canyon Times. "For the unfortunate millions of people that are suffering with chronic sinus issues, all of these sinus issues trickle down into every facet of their life. Because when you're not breathing through your nose, you're not sleeping well, and then you don't have the proper energy. You feel foggy all the time. Unfortunately, this happens slowly and chronically, and people accept this as the new norm and figure this is just something they've got to live with. Luckily that's not the case, and there are a lot of easy, simple things we can do to really improve their quality of life."

Yoga is an ancient practice, and its practitioners have studied the role of breathing for centuries, according to UK-based company Heather Yoga. Breathing through the nose, instead of the mouth, is strongly recommended by many yoga practices.

According to KTM Yoga, even though most people should breathe through their noses most of the time, as many as 60% of adults often breathe through their mouths. Hair and mucus in the nose act as filters that trap bacteria and dust. In addition, breathing through the nose also increases oxygen intake and boosts brain activity. Another benefit is that it helps to slow airflow, which widens blood vessels and slows your heart rate, which leads to a feeling of calm.

People who suffer from allergies and chronic sinus problems are more likely to breathe through their mouths, but mouth breathing can lead to oral health problems, according to McCarl Dental Group.

Mouth breathing dries up saliva, which allows bacteria and plaque to build up on your teeth, which can cause cavities, gum disease and chronic bad breath. Regularly breathing through your mouth can lead to strained jaw joints, which leads to snoring, sleep apnea, enlarged tonsils and a higher risk for airway disorders, such as asthma.
