A new wave of cold air is coming! Are you ready to keep warm?

Once it gets cold

Everyone tried every possible way to keep warm.

No matter how cold

Some methods still don't work

Be careful when using heating

Speaking of heaters, they are not just a tool for keeping warm, but also an "omnipotent god"! Underwear, socks, orange peels... everything that can make the best use of heaters is put on them by hardworking mothers. But be careful, there are some things that really cannot be heated on heaters...

1. Wash clothes with heated water

The large amount of water loss in the heating system will inevitably affect the heating temperature. The water in the heating system is softened water that has been treated with antiseptics and has chemical agents added. Using this water is harmful to health.

2. Drying clothes with heating can easily breed bacteria

The survey found that more than 80% of people put wet clothes on the heater to dry in winter. Drying wet clothes on the heater can easily create space for the growth of mold spores, especially Aspergillus fumigatus, which can be easily inhaled and cause potential lung infections.

3. Be careful when heating milk or soy milk

If milk and soy milk are heated on a heater for a long time, they will easily deteriorate and lose nutrients, so they should not be kept for too long.

4. Grilled frozen meat is prone to breeding bacteria

Putting frozen meat on a heater will make the meat cold inside and hot outside, which can easily breed bacteria. It is more hygienic to thaw it in water.

Be wary of these 4 types of "heating artifacts". In addition to hot packs, there are also hot water bottles, electric blankets, electric heaters, etc. They each have different safety hazards and different points to pay attention to.

1. Electric hot water bottle

There are two common types of rechargeable hot water bottles on the market, one is the electrode type and the other is the heating wire type. The electrode type hot water bottle has the risk of explosion.

In 2010, Taiwan had already listed "electrode-type electric hot water bottles" as a product that cannot be produced. However, this type of electrode-type electric hot water bottle has not disappeared from the market, but has become more common than the safer electric heating wire water heater.

Although there are safety risks, there is no need to be too afraid.

As long as you choose a regular manufacturer when purchasing, have 3C certification and product certificate, and the power cord is well sealed, and do not stick it directly to the skin when using it, but wear a few layers of clothes, there will be no problem.

2. Electric blanket

Every year, there are news reports of fires caused by improper use of electric blankets. In addition, children using electric blankets are prone to bedwetting, which can lead to leakage and very serious consequences.

Therefore, when using electric blankets, in addition to purchasing qualified products, you should also be careful not to use them for more than six years and do not fold them repeatedly and try to lay them flat.

According to the previous introduction, 40℃ is actually a relatively safe temperature. If you are really afraid of the cold, you can set a suitable temperature, turn off the power before going to bed, and it is recommended that the usage time should not exceed 4 hours.

3. Electric heater

Electric heaters or electric fans are the same. If used improperly, there is a risk of fire.

Be careful when using: do not cover it with quilts, clothes or other flammable materials, and keep it away from sofas, beds, and water sources.

Stay away from flammable objects! Stay away from flammable objects! Stay away from flammable objects! Important things must be said three times!

4. Heating mouse pad

In addition, there is another "heating artifact" that deserves everyone's attention, that is - the heating mouse pad.

The heating mouse pad looks "magical", but it is actually a miniature electric blanket. After two hours of continuous heating, the local maximum temperature can reach 68°C. If we are not careful, we will all become frogs in warm water, and be caught off guard by the comfortable temperature.

How to prevent frostbite?

Although frostbite is a common minor illness in winter, it is not easy to get rid of it. This is because the vasoconstriction and relaxation functions of the blood vessels in the area where frostbite has occurred are impaired, and it is very easy to relapse at the slightest "disturbance".

Therefore, be sure to take precautions:

1. In the cold winter season, you should wear masks, gloves, scarves, earmuffs, etc. when going out to keep warm.

2. You should strengthen physical exercise on a daily basis to enhance your physical fitness and promote blood circulation.

3. Wash your face and hands with cold water more often and dry them in time to improve the body's cold resistance;

4. People with underlying diseases such as diabetes and systemic lupus erythematosus should actively receive treatment;

5. For those who suffer from recurrent frostbite, in addition to medication, physical treatments such as infrared rays and helium-neon lasers can also play a certain preventive role and help get rid of the "entanglement" of frostbite as much as possible.

Can drinking alcohol keep you warm?

In winter, many people like to have a few drinks, thinking that it is both romantic and can keep out the cold. Can drinking really keep out the cold? In fact, it is "real heat, false cold".

Why is it called “real fever”?

Because you will indeed feel hot after drinking. When alcohol enters the blood vessels, it will cause the capillaries to expand, and the heat dissipation on the body surface will increase, making people feel hot.

However, the frequent heat exchange between the body surface and the outside world takes away the body's own heat, and excessive alcohol can cause dysfunction of the body's temperature regulation function, leading to excessive heat loss.

Therefore, after a short period of "fever" after drinking, you will feel colder and colder, which is what we usually call "cold after drinking".

Therefore, it is not advisable to keep warm by drinking in the cold winter, let alone go out after drinking, because the cold weather outside will aggravate the cold after drinking. At this time, once the resistance is weakened, the virus can easily take advantage of the opportunity to enter.

So this cooling

How should we keep warm?

Prepare clothes, hats, and scarves of appropriate thickness

Do a good job of cold protection for key protected areas

Drink more hot water and eat more warm food

If conditions permit, keep exercising to enhance immunity

No more fear of temperature drop!
