Common knowledge you need to know: Cover the toilet lid when flushing

Common knowledge you need to know

1. Flush or not cover the toilet lid

Some experts pointed out that if the toilet lid is opened when flushing, the instantaneous cyclone in the toilet can bring bacteria or microorganisms to a 6-meter-high air and suspend it in the air for several hours, and then fall on the walls and toothbrushes, mouthwash cups, and towels.

Now, most families use the toilet, wash, and shower in the bathroom. Toothbrushes, mouthwash cups, towels, etc. live in the same room with the toilet, so they are naturally susceptible to bacterial contamination. Suggestion: Develop the habit of covering the toilet lid when flushing.

2. Apply shower gel directly on your body

When taking a bath, if you apply shower gel or soap directly on your body, it will easily remain on your skin. It will damage the skin in the long run and may even cause allergies such as skin pain and itch.

Suggestion: When using shower gel or soap, use a shower ball to make foam first and then apply it to your body. This will not only save the amount, but also improve the decontamination effect. In addition, using a boar bristle brush once a week can effectively remove dead skin from the body. It is not only better than a bath towel, but also very labor-saving.

3. The strong gear of the washing machine is more energy-saving than the weak gear. Many people have not noticed that during the same long washing time, when the weak gear is working, the motor starts more times, that is, using the strong gear is actually saving power than the weak gear, and can extend the life of the washing machine. Because of the same long washing cycle, the impeller switching times is more times than that of the “ weak washing ” strong washing ” In addition, when washing a small amount of clothes, the water level should be moderate. Clothes float around in high water levels, lacking friction, not only can they not be washed clean, but also waste water and electricity.

Suggestion: Use strong washing steps, the water level of the washing should be moderate, and the dehydration time should be shortened. Generally, the clothes can be dehydrated for 2 minutes, and nylon products can be 1 minute.

4. Choice of cutting boards. The common cutting boards on the market are made of bamboo, wood and plastic, but qualified bamboo cutting boards should be made of natural plants. If a plastic cutting board cut with raw meat is completely cleaned, the residual bacteria will slowly reproduce, but the wooden cutting board will not, because the wood has a natural sterilization effect, the material is relatively strong and not easy to crack or deslag, and dirt is not easily stuffed into the gaps, it is cleaner and more convenient to clean.

Suggestion: Change the cutting board at home to wood, and also replace the plastic chopsticks that imitate ivory with wood.

5. Sleeping on the mattress quickly changes the bed

Experts believe that sleeping on the mattress will cause uneven force on the spring, which is not conducive to extending the service life of the mattress.

Sleeping on the mattress on the side of the mattress can easily lead to spring deformation and mattress depression. If the spring on the mattress loses elasticity, it will not be able to provide good support for the body. Lying on it will change the normal spinal curve of the human body, making the relevant muscles and ligaments tighten, making people feel tired the more they sleep, and when they wake up, they feel sore and painful back.

Suggestion: In the first year of use of the new mattress, it is best to change the front and back sides and placement direction every 2%; 3 months to make the mattress bear the same force, and then flip it about once every six months. In addition, mattresses must also be replaced regularly. Generally speaking, 8% mattress springs for 10 years have entered a period of decline. No matter how good the mattress is, it should be "retired" in 15 years.

6. Wash the hot non-stick pan with cold water after cooking, wash the pan with cold water. The hot pan suddenly becomes cold and the non-stick coating will fall off soon. If you put it cold and then wash it, or wipe it with wet paper, even a non-stick pan worth 60 or 70 yuan can be used for several years.

Suggestion: To protect the surface of the non-stick pan, you must wait for the pan to cool naturally after each use. Do not rinse the hot pan with cold water. If you encounter stubborn stains that are difficult to wash, you cannot use a rough and hard object such as a brush, otherwise it will damage the non-stick coating that is bonded to the pot. The correct way is to soak it in clean water for several hours before cleaning.

7. If there is a range hood, the window should be opened. Although the range hood can remove the oil fume, it cannot remove the exhaust gas generated when the gas is burned. Compared with oil smoke, this invisible exhaust gas is more harmful to the human body.

Whether it is a coal-fired stove, petroleum liquefied gas stove or electric stove, it will produce carbon monoxide, carbon dioxide, nitrogen oxides, inhalable dust particles and other air pollutants. Excessive inhalation of carbon monoxide will have an adverse effect on human heart and lung function. Nitrogen oxides can also lead to lung lesions, asthma, bronchitis, emphysema and other diseases, and even lead to pulmonary fibrosis.

Another thing that is easy to overlook is that some families often only turn on the range hood when cooking. In fact, the entire cooking process, including steaming, boiling and stewing, will be exhausted, and the emission time is longer than the cooking fume. In addition, the stove is far away from the range hood, so the exhaust gas is easily stuck indoors.

Suggestion: From the moment you open the stove, it is best to open the range hood and windows to keep it ventilated at any time.

8. Air freshener pollutes air

The ingredients contained in air freshener may cause harm to the human body. At present, the air fresheners sold on the market are basically composed of ether, flavor and other ingredients. Some components of the gas produced by chemical decomposition in the air are themselves air pollutants. This actually aggravates the degree of indoor air pollution, and long-term use will cause adverse stimulation to the human body. In addition, the aromatics contained in air fresheners can also cause harm to the human nervous system.

Suggestion: The room should be kept ventilated and the air should be kept circulating. After using chemical agents, do not close the window immediately, and ventilate for at least half an hour. You can place some green plants indoors, such as spider plants, aloe vera, etc. to absorb polluted gases in the air.

9. It is not a good thing to use multifunctional washing powder with caution. The more functions it is, the more additives it means. Surfactants, whitening agents, and builders all contain ingredients that are harmful to the human body.

Studies have shown that commonly used builders are harmful to the human liver; surfactants can destroy the stratum corneum of the skin and cause rough skin; the alkaline substances contained in powerful laundry detergent can not only absorb water, but also destroy the human cell membrane and denature tissue proteins; the synthetic fragrances in the fragrance detergent will cause allergies in some people; the organic chlorine and fluorescent agents contained in whitening laundry detergent are toxic substances, which are easy to accumulate in the human body and cause damage to health.

Suggestion: For health, it is best to choose ordinary laundry detergent with simple functions, few ingredients and light odor. If you use multi-functional laundry detergent, you must pay attention to repeated cleaning to minimize the residue of laundry detergent on the clothes.

10. If the tiles are too white, the eyes will be damaged by the white. The metallic tiles have strong reflection, which will cause light pollution and are not suitable for large-scale use.

Light pollution can stimulate the retina of the human eye. Generally speaking, after watching TV for several hours in a row, a person's vision will temporarily drop by 30%. If you live in a living environment with smooth walls and ground for a long time, light reflection will stimulate the retina, exceeding the coordination of the eyes, causing eye fatigue and even reducing visual functions.

Suggestion: When decorating, it is best to choose matte tiles; try to use floors instead of floor tiles in study and children's room; if polished tiles are used, try to turn on small lights at home as much as possible, and avoid direct lights or reflections affecting the eyes; white and metallic tiles have strong reflections, so it is best not to use them in the living room on a large scale.

11. When using frozen meat, some people often use hot water to thaw frozen fish, livestock, poultry and other meats placed in the freezer room of the refrigerator, they often use hot water to thaw and cook immediately. In fact, this method is unscientific.

Because during the quick freezing of meat, the intracellular fluid and extracellular fluid quickly freeze into ice, forming crystals between the flesh fibers and the cells. The crystals of this juice are the most valuable protein and delicious substance. If thawed with hot water, not only will it lose some of the protein and the aromatic substances in it, but more importantly, it will produce a strong carcinogen called propionaldehyde. Therefore, frozen meat must be thawed in cold water or slowly and naturally dissolved.

Suggestion: The scientific method of thawing is to soak frozen fish, livestock, poultry and other foods in cold water or place at 4℃ to 8℃ to thaw naturally.
