In our daily lives, we have many things to touch and use every day, but never really understand。
There's a lot of little details, and there's interesting, practical cold knowledge behind them. These little skills can help us escape trouble, save time and make life easier。
Today, nine extremely low-rate, but particularly low-tempered, knowledge of life is being collated, and 90 per cent of the people don't know it
1. Refrigerator should not be packed in full
A lot of people buy food, and it's customary to fill the fridge with food, which is considered to be cost-effective and fresh。
In fact, the most suitable storage ratio for refrigerators is about 70%。
The air cycle is required inside the refrigerator in order to be evenly cooled. Overstretching, which prevents normal circulation of cooling gases, not only makes the cooling less effective and more likely to breed bacteria, but also increases electricity consumption and accelerates the deterioration of food products。
2. The groove in the hand of the plastic bag is useful
The plastic bags are normally purchased with two small dents on both sides。
Many people think it's just a design, but it's used to bind plastic bags. When there are too many bags to hold hands, the dents are tied together, the areas of stress of the hands become larger, and the liftings will no longer be red hands。
3. Cell phone power left 20% recharge
The vast majority of people are used to charging, filling and recharging。
Lithium batteries are most afraid of two states: long-term full power and electricity depletion。
Maintaining 100% power over a long period of time accelerates battery aging; the use of electricity to automatically shut down can directly impair battery life. Best charge zone: 20 ~ 80 %, mobile phones are the most durable。
4. Do not start at the top of the head. Wash
Most people bathe, the first move is to wash their hair, which is the wrong bath order。
The human body moves from a cryogenic environment into a hot-water bath and the veins expand rapidly. If hair is washed first and blood is concentrated in the head at short notice, it is highly likely to lead to a lack of blood in the brain, prone to dizziness, panic and even to fainting of the old body。
Correct sequence: first wash your face, then wash your limbs, then wash your hair。
5. Stripped garlic in the water, automatically skinned
Many people hate to peel garlic, which is thin and sticky, and which takes time to get dirty。
Share a lazy trick: open up the garlic, immerse it in a warm water for three minutes, relax the garlic, squeez it, and it's free from the skin, save time。
The opening of windows at night does not amount to ventilation
Many people sleep in a window that opens a gap to ventilate, thinking they can clean up indoor air。
There's a common sense in cope: cold air sank at night, sank. When windows are opened at night, the outdoor air and dust is sunk into the bedroom, the air quality deteriorates。
A really good time frame for ventilation: 9 a. M.-4 p. M。
7. Keep the film clean
When you use the membranes, you're all laced in food and fruit。
The membranes are oversealed and the water vapours from the food are not excreted. They condensate and flow back to the surface of the food, accelerating the deterioration and decay of the food。
Correct use: just a light covering of the film, not a dead seal。
8. The water that just boiled, don't put a lid on it
It's the instinct of a lot of people to put a kettle cap on the first time they boil water。
Small amounts of volatile hazardous substances remain in the water when running water is burned. When it boils, the lid is capped and the hazardous substances are not volatilized and all are locked into open water. It is recommended that the fire be opened for two minutes and that the lid be placed on。
9. Sitting longer than staying up late
Many are afraid to stay up all night and are neglecting the harm of sitting long。
Scientific data indicate that two hours of continuous sitting, slower blood circulation, reduced metabolism and damaged lumbar vertebrae, and more than six hours per day, causing physical injuries well above one hour per day。
It is recommended that each person sit for 45 minutes and rise for 3-5 minutes。
Life is full of learning, with a lot of little details that often determine our quality of life. Learn these little things, easy to solve the little problems in life。
