How can the elderly do tongue exercises to prevent snoring?

　　A new study by Australian health experts has confirmed that consciously doing tongue exercises every day can help relieve snoring.

　　Tongue exercise is to let the tongue do more exercises. The so-called tongue exercises specifically include: lightly brushing the surface of the tongue when brushing teeth, extending and retracting the tongue to the maximum extent, rolling the tongue left and right, and moving the tongue as much as possible when eating, etc. Experiments have proven that after 15 minutes of tongue exercises every day, the symptoms of snoring and obstructive sleep apnea can be greatly reduced, and the quality of sleep is also greatly improved.
