when people are bored, nervous and anxious, they often do subconscious small actions such as biting nails and licking lips. Recently, an article published on a website pointed out that these small actions seem harmless, but sometimes they are harmful to health.

bite your nails.

Dr. Michael shapero, a dermatologist in New York, said that biting nails when nervous may hurt nails and surrounding skin, cause bleeding or infection, and cause hand and mouth bacteria to infect each other. Sticking tape or chili oil on your fingers can help correct this bad habit.

scratch head.

Dr. arell ostad, a dermatologist in New York City, said that frequent scratching and pulling of the hair will damage the hair roots and cause hair loss or infection.

lick your lips.

Whitney Bowie, a doctor of dermatology in New York City, said that licking lips when nervous will make digestive enzymes stick to the skin, resulting in cheilitis and lips are more likely to dry and crack. Such people should look for healthier ways to relieve stress, such as sports and singing.

bite the pen head.

Dr. Ted Mayart, a medical expert at the University of Rhode Island in the United States, said that there are a variety of pathogens hidden in the pen head. Biting the pen head can easily lead to gastrointestinal diseases or influenza. In addition, it may damage teeth and gums.

love to touch your face. Jessica clent, a professor of clinical dermatology at the Southern Medical Center of the State University of New York, said that touching your face or picking up acne often leads to epidermal damage and infection. Once you pick up bleeding, it is easy to leave permanent scars. It is recommended to use non irritating topical ointment or moisturizer locally.

twist your neck.

forcibly twisting the neck will make the spine “cluck”. Although this may make you feel relaxed, over time, it will loosen the surrounding ligaments, easily hurt, wear small joints, and lead to arthritis and other diseases.

clench your teeth.

when the pressure is high, many people will “clench their teeth”. In fact, this will cause tooth damage or fracture, and even mandibular joint damage in severe cases.
