What about sunburn and scald? Remember the first aid!

How to deal with sunburn and scald that are most likely to occur in summer?

Sunburn: milk is applied to the sunburn.

Feng Aiping, chief physician of wuhan union hospital Dermatology Department, introduced that a towel should be cold-compressed, soaked in water, frozen in the refrigerator for a few minutes, and then applied to the sunburn for about 10 minutes, 2 ~ 3 times a day.

Apply milk to the sunburn, put a cloth in the liquid mixed with milk and ice water, and then apply it to the sunburn. Whey protein and lactic acid in milk have anti-inflammatory and soothing effects.

Try aloe lotion or gel aloe vera with anti-inflammatory effect, which helps to relieve redness, inflammation and sunburn. Applying it to sunburned skin will make you feel cool and pleasant as never before. It is more comfortable to ice in the refrigerator before using it.

Apply ointment containing steroids because steroids can diminish inflammation, relieve pain, make you feel comfortable and relieve burning sensation.

Be sure to drink plenty of water. Sunburn will make you dehydrated. Remember to replenish enough water as soon as possible.

Use fragrance-free moisturizing milk to moisturize lotion or moisturizing oil with fragrance-free essence, and apply it several times a day. Edible oil is also acceptable. You can also use SPF30 or higher sunscreen lotion (but don’t use chemical ingredients) or wear clothes to protect your skin from damage.

Don’t put ice cubes on the sunburn, because putting ice cubes on the sunburn will cause frostbite on the sunburn skin surface and cause too much damage to the skin.

If you have these symptoms, go to a doctor and get sunburned over half of your skin. There are blisters; Have systemic symptoms, such as fever, chills or severe pain; There are symptoms of infection, such as redness of the skin or aggravation of pus.

Scald: Flush with tap water for half an hour.

Cui Yuyan, a Zhongda Hospital affiliated to Southeast University, said that most parents were in a hurry to send their children to the hospital after their children were scalded, and even used "indigenous methods" such as soy sauce and toothpaste to rescue them, which led to infection and aggravated their illness.

Yu Bing, Department of Burn Plastic Surgery, Zhongda Hospital affiliated to Southeast University, reminded that burns can be divided into first-degree burns (erythema and red skin); Second degree scald (blisters, blisters on the affected area); Third-degree scald (necrotizing, skin peeling).

First-degree scald: it should be washed with running water immediately, that is, "cooling treatment", preferably for half an hour. If it is inconvenient to wash, it can also be applied with a cold towel to take away the heat and reduce the degree of burns;

Second-degree scald: after a certain period of "cooling treatment", it is still local redness, fever, unbearable pain, and blisters appear on the injured area. Don’t break the blisters at this time, and go to the hospital for treatment quickly;

Third-degree scald: The fat, bones and muscles under the skin are imitated and pale as leather, but the pain is not severe at this time, because many nerves are also damaged together. At this time, pollution and re-injury of the wound surface should be avoided, drugs should not be rubbed, and it should be kept clean and sent to the hospital for treatment quickly.

The most direct treatment after accidental scald is to wash with tap water, and it is not recommended to apply ice cubes to the affected area to prevent frostbite. It is really necessary to use ice. It is recommended to wrap it with clean and soft gauze and then apply it to the affected area for half an hour. [detailed]

Three life tips to stop hiccups

Although burping is not a disease, some people burp from time to time, and once they burp, they can’t stop, which still has a certain impact on life and work. Sun Yan, deputy director of the Department of Gastroenterology, the Third Affiliated Hospital of Guangzhou Medical University, teaches you to use some life tricks to stop burping, but she reminds that continuous burping for more than 24 hours may be a sign of some diseases.

A brief hiccup does not require medical attention.

Hiccup is actually a physiological phenomenon caused by diaphragm spasm. In fact, burping is beneficial. Burping helps to expel gas from human lungs and help relieve flatulence in the stomach. Therefore, there is no need to consult a doctor for brief hiccups in daily life.

However, frequent hiccups will still have an impact on life. To this end, Sun Yan suggested that the following small methods can be tried when hiccups occur daily.

1) divert attention. There is a saying that it is good to be scared when burping. In fact, this is one of the ways to relieve burping, and to eliminate bad emotions by diverting attention.

2) Take a sip of warm water and swallow it several times. If you can tilt your upper body forward to a position where it is parallel to the ground, drink water in this state.

3) Take a deep breath, hold it for as long as possible, then exhale slowly and repeat several times. In addition, you can also cover your mouth with a mask when inhaling, forming an environment with increased carbon dioxide, stimulating the respiratory center of the human body, thus reducing the irritating excitement.

You don’t have to see a doctor if you can restrain it. If it persists and affects life, work and sleep, you can go to the hospital for consultation. There are some drugs that can help treat hiccups.

Be careful when burping for more than 24 hours.

Long-term persistent burping, such as burping for more than 24 hours, needs attention. Persistent hiccups are called "intractable hiccups" in medicine. If there is a disease in the stomach, persistent hiccups may cause tearing of esophageal mucosa and even gastrointestinal bleeding. In addition, "intractable hiccups" may also indicate some diseases, such as stomach tumors, liver cirrhosis, cerebral infarction, etc. Therefore, if this kind of hiccups occur, it is recommended to consult a doctor.

Just use 3 tricks and never worry about cleaning your hair again.

It is the dream of many women to have a beautiful black hair. But when this beautiful hair falls off, all it brings is trouble. Especially under the sofa, closet gap, sewer and other sanitary corners, hair often accumulates, which is quite difficult to clean up. The following are several cleaning methods recommended for everyone.

1. Hair on the floor

You can put a pair of old silk stockings on the broom. When sweeping the floor, hair and dust will be easily adsorbed on the silk stockings because of static electricity.

2. Cloth hair on sofas, sheets and sweaters

You can cut off a wide piece of tape and stick it on it a few times, which can be easily removed.

3, sewer hair

Li Hongzhu, an associate researcher at Tianjin Institute of Medicine, reminded that the hair in the sewer is hidden and difficult to clean, so many people think that it can be done with pipe dredge. Actually, the hair is made of protein, which is not easy to corrode. Using some acid-base solvents will not work, and it may damage the pipeline.

It is best to choose a pipe mouth with a sieve to clean the accumulated hair on it regularly. If it’s a bouncing sewer, try a tailor-made "sewer hair cleaner", which is made of plastic and has gears on both sides. After reaching into the pipe and turning it, the hair will be pulled out. [detailed]

Recently, a new user named "996icu" appeared on GitHub, an international open source community. He built a new code warehouse named "996.ICU", pointing out that the "996" working system prevailing in Internet companies seriously violated the labor law. Subsequently, this quickly became a professional group of programmers and even a national topic.

The so-called "996" working system refers to working hours from 9: 00 am to 9: 00 pm, with one hour off at noon and evening, totaling more than 10 hours a day, working six days a week and working 72 hours a week. This working time, regardless of whether there is overtime pay, has violated the labor law.

This kind of working system gives people the first impression that enterprises are squeezing employees, but if programmers are weak, then why can programmers get a high salary of 20 thousand to 30 thousand? In fact, programmers are not a vulnerable group, but a group with high salary, high quality, high skills, high attention and high voice. The various factors and logic contained in their rights protection actions are more complicated.

In the consumer market, there are two important methodologies to judge whether an enterprise has violated the interests of consumers: Is there competition? Is consumer sovereignty still there?If the answers to these two questions are yes, I don’t think there is any big problem.

Similarly,On the issue of overtime and wages, there are also two methodologies: is the enterprise in a competitive state in the labor market? Can job seekers choose?If these two answers are in the affirmative, then the problem will not be too serious.

Moreover, under these two premises, safeguarding rights is definitely not as simple as it seems. There must be deep-seated factors besides the simple explanation of "enterprises squeezing employees".

It is worth noting that,Opposing "996" is more of a group appeal, but it has not become a universal behavior of individuals in the group.

Theoretically, programmers have the ability to get rid of the 996 working system by individual choice. For example, ask if you want to work overtime regularly during the interview; Resignation from the company that announced the implementation of 996; You can also choose to go to a smaller company. This kind of dispersed individual behavior will eventually form a group trend, which makes the company dare not implement the 996 working system at will.

In fact, the high salary of programmers comes from this mechanism. Programmers make choices independently and dispersedly, and use the method of "voting with their feet" to make enterprises offer high salaries. Finally, the systematic situation of programmers’ general high salaries is shaped.

Why can the decentralized and independent individual selection mechanism bring high salaries to programmers, but it can’t make them get rid of 996?

From the industry point of view, the Internet and IT industries have fierce competition and rapid development, and the company must strive hard; From the specific nature of work, programmers are often faced with urgent needs and often have unexpected events to solve, which will lead to frequent overtime. The nature of business makes overtime work a "just need" for employees.

From a larger perspective, China’s overall income is not high. According to the economic law, when the income is not high, people tend to work more in exchange for more wages. This makes employees’ motivation against overtime weak. Just as a programmer told reporters: As long as the money is in place, everything can be said.

In fact, the IT industry has experienced explosive growth in the past 30 years. Entrepreneurship, equity and listing have constructed one wealth myth after another.People in IT companies are willing to work overtime, which is largely due to the wealth effect. Entrepreneurship, options, bonuses and dividends all encourage employees in the industry to work overtime.

The industry’s just need for overtime, employees’ expectation of wealth and weak resistance to overtime often form a culture, which leads to all kinds of unnecessary overtime. For example, in a department or a company, when someone works overtime, others are forced to follow suit. Over time, it has become the default consensus that Internet companies work long hours and are not fixed. In the end, the company unscrupulously stood up and implemented the 996 system, turning overtime into a solidified system.

However, the Internet industry is developing at a rapid pace, and many things have changed.

From the perspective of the big economic law, with the increase of wage level, with rich income, the marginal effect of income begins to decrease, and workers will think that leisure is more important than income growth, preferring to increase leisure and reduce working hours.

From the time point of view, "996" was mentioned frequently from about 2014, and it took about five years for this outbreak to be a hot topic. Five years ago, it was the time when the myth of entrepreneurship and wealth creation brought by the mobile Internet kept emerging. Five years later, the economy is in a new normal, the Internet’s wealth-making ability is no longer beautiful, and the incentives are reduced.Without money, overtime culture can’t continue.

Therefore, when the "996ICU" action appeals, awakens and influences the programmers in China, the "996" overtime system will be more severely challenged. Internet companies in China should conform to this general trend and maintain long-term sustainable development with better labor protection and welfare.

Of course, at the same time, the characteristics of the Internet and IT industries also need to be respected. For example, your APP can’t be used, and you definitely want programmers to work continuously to solve this problem. Therefore, the introduction of flexible working hours is also inevitable.

It is worth noting that the implementation of flexible working hours in China needs the approval of relevant supervision departments, so law enforcement departments also need to respect the diversified market formats and make appropriate adjustments.Only legal and clear overtime can make those illegal and vague overtime more obvious, so as to better regulate it.
