If you have this thing at home, it's time to change it

Some things in the home will have problems of one kind or another after being used for a long time. Never adopt the mentality of "one day is enough", because perhaps it is this "reluctance" that will threaten your health. Experts remind that it is more beneficial to health to clean and replace the following household items periodically.

Change your pillow once a year

The oil on the hair and scalp will penetrate into the fibers and pillow core of the pillow after long-term accumulation, thereby breeding bacteria and easily causing allergies and respiratory diseases. If your pillow has lost its elasticity or has become uneven, it means that your pillow should be replaced.

Replace mattress every 5-10 years

Although a good mattress can be used for 9-10 years, even the best quality mattress will lose its support after long-term wear and tear, thus affecting the quality of sleep. In addition, there are many stains on the mattress that cannot be cleaned, which makes us sleep directly with bacteria. Therefore, it is recommended that you replace your mattress every 5 years, especially for people who have poor sleep. A study by Oklahoma State University found that among people who replaced their mattresses every five years, most had better sleep quality and less back pain.

Check the air conditioning filter every 6 weeks

Generally speaking, the lifespan of a household air conditioner is more than 15 years, and proper maintenance of the filter plays a decisive role. It is a good idea to check and clean the filter every 6 weeks, especially in humid weather.

Vitamins stored for more than 2 years

A test conducted by Harvard University in the United States found that in order for vitamin medicines to maintain their effectiveness, they can only be stored for 2 years even if they are kept in a cool and dry place. Therefore, if you have such medicines at home, it is best not to take them even if they have not expired.

Water purifier should be replaced every 6 years

General household water purifiers use the principles of filtration and osmosis to remove microorganisms, bacteria and other substances from tap water. However, after long-term use, the filtering function of the water purifier will not only decline, failing to play a thorough cleaning role, but will also breed some bacteria, which is not conducive to people's health.

Contact lens cleaning solution should be changed every 3 months

Louis Sclafani, associate professor of ophthalmology at the University of Chicago Hospital, pointed out that once the lid of the cleaning solution is opened, bacteria can easily come in, increasing the risk of eye infection. In addition, it is best to replace the box for storing contact lenses every three months.

Replace your toothbrush every 3-4 months

The American Dental Association believes that when toothbrush bristles are worn or old, they not only fail to clean teeth, but make them more susceptible to "decay."

Eye makeup should be thrown away after 6 months of opening

After the packaging of eye cosmetics such as eye shadow and mascara is opened, they will be repeatedly exposed to the bacterial environment. If used continuously for 6 months, the preservatives in them will basically no longer work. Failure to discontinue use may increase the risk of eye infection.

Use rubbing alcohol until the last drop

The alcohol and water solution remains stable even when exposed to air and effectively kills any microorganisms and bacteria that enter the bottle.
