Description

Technical Field

[0001] The invention relates to the technical field of mattresses, and in particular to a Chinese medicine mattress for improving sleep and a preparation method thereof. Background Art

[0002] With the acceleration of the pace of life and the increase of work pressure, people's physical fatigue is gradually accumulating and increasing; sleep, as a best habit to relieve stress, restore energy and ensure physical and mental health, plays an important role in relieving fatigue and resisting the invasion of bacteria and viruses. Sleep is an active process of the human body, which can restore the spirit and relieve fatigue. Adequate sleep, a balanced diet and proper exercise are three health standards recognized by the international community. However, with the increase in the number of insomniacs, in order to arouse the public's awareness of the importance of sleep, in 2001, the Global Sleep and Health Program sponsored by the International Mental Health and Neuroscience Foundation launched a global activity, which focuses on attracting people's attention to the importance of sleep and sleep quality. When the quality of sleep cannot be improved through normal diet or changes in lifestyle habits, it is often necessary to take medicine for corresponding treatment. However, most Western medicines for the treatment of insomnia have strong side effects and are highly dependent. In the end, more and more medicines are taken, but the quality of sleep is getting worse and worse.

[0003] Mattress is an item between the human body and the bed, used to ensure that the user gets a healthy and comfortable sleep. With the continuous development of society, in order to meet people's requirements for mattress comfort, humanization and sleep quality, functional mattresses have been more and more widely used. Most mattresses in the prior art are made of yarrow, sponge and springs, which are easy to deform and grow mites and bacteria, endangering people's health. In addition, the work rhythm and lifestyle of modern people have changed greatly, and the number of insomniacs is increasing. The market calls for products that are beneficial to healthy sleep.
