In 2009, I conducted a survey and selected 59 healthy people to sleep for 28 consecutive nights on their mattresses and 28 nights on new, medium-hard mattresses. Finally, the stress levels of the 59 respondents were assessed, including worry, sorrow, tension, and headache. The survey found that the new bed significantly reduced the sense of stress and reduced the body's discomfort.

The mattress became an allergen

Here mainly refers to dust mites. Dust mites can only be observed with a microscope. They mainly feed on human dandruff, so they proliferate faster on the bed. Dust mites are important allergens that cause allergic diseases such as asthma, allergic rhinitis and eczema. According to WebMD, the largest medical health service website in the United States, about 20 million Americans are allergic to dust mites. Regularly wash the sheets and pillowcases with hot water to remove dust mites. Buy a mattress cover that is better with a mattress that says "to prevent allergies". Alternatively, you can use a vacuum cleaner to clean the mattress.

The hardness of the mattress varies from person to person.

There is no uniform standard for a mattress that is too hard or too soft. On the same mattress, a person weighing £250 may think it is soft, but it may be too good for a person with £125. "Medium soft mattress" sounds like the most reliable, but only if you really lie on the mattress for a while to understand whether it is appropriate. So before deciding to buy a mattress, lie on the mattress for at least 20 minutes to see if it is comfortable.

Decisively replace the damaged mattress

Damage to the mattress padding or a problem with the spring indicates a new mattress, but this is not the only reason to replace the mattress. According to USA Today, when you find that sleep is not good before, you should consider changing the mattress, especially if you find that sleeping in someone else's home is more comfortable than at home.

Don't play mobile phone in bed, want to work

The bedroom should be a place to sleep and relax. If you are still thinking about work, you will find it hard to sleep. Similarly, don't play electronic devices such as mobile phones after going to bed. The blue light emitted by electronic devices will interfere with the natural sleep mechanism of the brain, which will make people feel very clear and affect sleep.
