1. Chewing promotes saliva secretion and protects oral health anytime and anywhere.
Many people think that chewing sugar-free gum will "stick" food residues in their mouths, but it is not. Studies have shown that saliva does play a protective role. The seemingly ordinary saliva has the functions of cleaning and antibacterial, and chewing can stimulate saliva secretion, wash away food and other residues in the mouth and inhibit the growth of bacteria, which is one of the most powerful preventive mechanisms of the human body. Chewing sugar-free gum for 20 minutes after meals or snacks is a simple and easy way in daily oral health care, which can be done anytime and anywhere. Love your teeth is a good habit worth recommending.
In fact, the anti-caries function of sugar-free chewing gum has long been certified by American Dental Association (ADA), World Dental Association (FDI), Chinese Stomatological Association (CSA) and many other professional institutions at home and abroad. In the newly published Oral Health Guide for China Residents, the Ministry of Health also pointed out that "chewing sugar-free gum can stimulate saliva secretion, reduce oral acidity, and help to freshen breath and clean teeth". As a simple and easy way to protect oral health, you can kill two birds with one stone while enjoying sweetness and delicacy.
2. Chewing helps relieve stress.
Modern scientific research provides physiological experimental basis for human chewing demand and "chewing decompression".
At the end of the 20th century, foreign experts adopted the latest technology of electroencephalogram (EEG), and found that chewing gum can enhance alpha brain waves. However, research shows that alpha brainwaves are a sign that the spirit is in a calm state, and the weakening of alpha brainwaves is closely related to the emergence of emotions such as tension and anxiety. It can be concluded that chewing gum enhances alpha brain waves, thus making the emotional state relatively relaxed. Therefore, experts believe that chewing gum helps to relieve tension. In a survey conducted in the United States, 56% of the respondents agreed that chewing gum helped me overcome my daily nervousness.
The latest research published by Andrew Scholey of Northumbria University in 2009 shows that when mild and moderate acute psychological stress is induced by using experimental procedures, multiple cognitive tasks are completed at the same time. Compared with people who don't chew gum, subjects' self-evaluation alertness is significantly improved, their self-scores of state anxiety and stress are significantly reduced, and cortisol level, an indicator of physical stress state, is reflected in saliva. At the same time, when chewing gum, subjects
