If your pillow person is very good at snoring, then you don't want to sleep well, at this time you will be distressed: what can be done to stop snoring immediately, in fact, snoring may be caused by incorrect sleeping position, or it may be caused by dryness in the room, and you do not need to take medication.

2. As long as 3 4 drops of mouthwash are diluted with warm water before going to bed, the snoring can be weakened and stopped. It also has a special anti-snoring effect, which can increase the blood of the throat mucosa**, and the snoring will be weakened or stopped.

3. Ten grams of gentian grass and angelica sinensis. Boil method: soak for more than 1 hour, pour on fast heat, slow heat for 20 minutes, pour out the potion and then boil it a second time in the same way. Mix the potion twice and take it in two parts. Take it before bedtime and take it for three nights.

4. Before going to bed at night, rub the center of the eyebrows with the thumb knuckle, and there is a small depression on the bridge of the nose, press it for a while.

5. Pinch the thumb nail and press the tip of the index finger, leaning on the outside, on the left and right of the nail gap, and press it for a while.

6. The glass ball method sews a glass marble loosely into the shoulder blade under the collar of the pajamas, so that it can slide left and right. Snorers generally do not snore when lying on their side or stomach, and when they want to turn around and lie on their back, they will press the glass ball on their back, so that they will immediately turn to lie on their side or stomach, so that the snoring will not appear or be significantly reduced. Or sew a small pocket in the middle of the back of the pajamas, and put a small child's ball or tennis ball in it, so that the snorer will not lie on his back, and it can also greatly reduce the snoring sound.

The above is the relevant introduction of what to do to stop snoring immediately, and patients with snoring should pay attention to strengthening physical exercise and maintaining good living habits.

Silicone earbuds: Generally speaking, earbuds made of silicone have the performance of repeated use, but because the softness of silicone is too low, long-term wear often causes discomfort and even swelling pain in the ear canal. Also because silicone is not as soft as a sponge and cannot fit snugly against the wall of the ear canal, the sound isolation effect is often not as ideal as that of sponge earbuds.

Sponge earbuds: The noise-proof earbuds made of low-pressure bubble mold material and high-elasticity polyester material have a smooth surface, slow rebound, no swelling and pain in the ears when used, and the sound isolation effect is between 25db-40db. These earbuds are ideal for sleeping every night, but they cannot be used repeatedly due to the weakening of the slow rebound effect after washing, and generally speaking, sponge earplugs are disposable after use.

However, with the development of science, there are also some sponge earplugs on the market that can be used repeatedly for more than half a year and can be scrubbed.

Wax earplugs: Wax earplugs are the originator of noise-blocking earplugs, which can be softened by hand and shaped to fit the ear canal. However, the disadvantage is that it is not hygienic enough, and the wax may remain in the ear canal, which is not easy to clean. And I wore it for a long time.

There will be a feeling of swelling and pain in the ear.

I have been using a bullet-type earbud called PU material for a long time: Pinqing noise-canceling earbuds, slow rebound, easy to wear, mainly due to the characteristics of the material, with tens of millions of small pores, with no bloating pain.
