On the question of whether frowning causes wrinkles, research has given a clear answer. Every time the frowning brow is stretched, the ** on the forehead will be carved with deep lines. These lines, like tiny paintings, record every emotional fluctuation. When they recur and accumulate gradually, they will eventually weave into wrinkles that we don't want to see.

Why do doctors look at a patient's tongue when diagnosing a condition? What's the secret? The state of the tongue, which is an important basis in TCM diagnosis, is regarded as a "mirror" to observe the health of the human body. A healthy tongue has a pale red color and is moderately moisturized, and its elasticity can be felt when you press lightly. And when the body temperature rises, the humidity of the tongue decreases, and sometimes even cracks. If the condition worsens, the tongue will turn white. When the stomach and intestines are not functioning well, the function of water metabolism is weakened, and the tongue coating turns white and covers the entire tongue. These subtle changes, for doctors, are important clues to diagnose diseases. Therefore, in daily life, we can also understand the health of the body by observing the state of our tongue. 
To sum up, it is not difficult to protect** and eye health and care for the body. Measures such as reducing frowning and wearing ** glasses correctly can protect our health. At the same time, mastering medical knowledge such as tongue diagnosis can help us better prevent diseases and maintain health.
