Pillows should be changed every six months and dried every three days

A survey in the United States shows that nearly 70% believe that a comfortable pillow is a necessary condition for good sleep. However, it is precisely because people attach importance to the comfort of pillows that the more comfortable the pillow is, the easier it is to extend its service life. So, how often should I change my pillow? The Huffington Post published an article on August 4, which published the answer given by Dr. Robert Oxman, chairman of the board of directors of the American sleep and Health Research Institute – even if the pillow is comfortable and expensive, it is better to replace it after about six months of use.

Dr. mark Newstrom, an allergy and asthma expert in Kansas City, said that after a long time, the pillow would not only accumulate a large number of stains, Oils and dead skin cells that could lead to acne, but also easily hide dust mites. Dust mites like the gaps on pillows most, which can induce allergy or asthma in people with allergic constitution. These people account for about 20% of the total population. In the allergic population, about 2 / 3 people are allergic to indoor dust mites. Rhinitis is a perennial problem. It’s best to check whether it is caused by dust mites on pillows. In principle, “six months” is the service life of pillows, but for the industrious and thrifty Chinese, this frequency is a bit “luxury”. If you can dry pillows and wash pillowcases frequently, it will help to remove dust and mites. It is recommended to dry it once every three or five days.

Dr. Oxman said that when buying a new pillow, one should keep in mind that a comfortable pillow should fill the gap between the head and the shoulder when lying on the back; When lying prone and supine, the pillow height can be properly lowered, while when lying on the side, the pillow height can be properly padded higher. Dr. Oxman also said that the service life of a mattress is generally 5 to 10 years. When replacing a new mattress, the pillow should also be replaced. The reason is that the hardness and support of new and old mattresses are different, and the gap between the head and the shoulders is naturally different.
