Young female white-collar workers have become a high-risk group of “sub-health”. They often search the Internet or magazines for the most popular ways to maintain their health, and then take all the orders. Do you know what are your misconceptions about daily health care?
myth 1: eating at night leads to obesity
According to a survey, four out of every 10 Americans work at night, which means that many people can’t have dinner until very late. Will late dinner lead to obesity because we can’t consume these calories during sleep? Nutritionist Eric Blackberg said: “it depends on the situation. Eating late at night will not generally lead to increased fat, unless you eat more calories that day than you usually do. Many people want to eat something else for a change when eating dinner. They will eat some ice cream and fried potato chips. Eating these foods at night will often cause obesity.”
Myth 2: muscle will turn into fat if you don’t exercise.
For those who spend three to four days a week on physical exercise, will their muscles become fat if they stop exercising? Health preservation master Donna Richardson juer said: “this will not happen. Muscle is muscle and fat is fat. The two will not be transformed into each other.”
myth 3: pay attention to drinking eating and exercising are equal to losing weight
If you think that doing these two things well is enough to ensure weight loss, you are absolutely wrong. You may have overlooked another major factor: sleep problems caused by weight loss. Dr. Yves van coulter, who studies sleep at the University of Chicago, said: “Americans are also the most overweight and obese people. Maybe we should consider the possibility that there is a relationship between obesity and sleep. Lack of sleep will lead to our appetite disorder.” Everyone has a normal sleep time. If the sleep time is less than this time, even if the difference is only one hour, it will lead to hormone imbalance in his body.
After analyzing the blood of these sleep deprived people, it was found that the content of leptin, which controls appetite, in their blood decreased. When we eat enough, leptin will “tell” us that we are full. At the same time, the content of plasma ghrelin in blood increased. The role of plasma ghrelin is that when our body’s caloric supply is insufficient, it will send a hunger message, which will prompt us to start eating.
myth 4: pure natural ingredients make your hair Beautiful elegant
Do you think natural herbal ingredients are better than chemical ingredients in hair care? This is a wrong understanding. Paula Peigang, an internationally renowned cosmetics expert, said: “the herbal ingredients in hair care liquid actually have no effect on cleaning hair. The chemical synthetic ingredients that have never been praised by people should be the ones that really care for human hair.”
myth 5: waxing is better than shaving for hair removal
Shaving has a history of thousands of years, and waxing has been used as early as ancient Egypt. Which of the two methods is the best choice? Dermatologist pat Axler said: “after waxing your hair, you can pull it out below the surface of your skin. So it takes 3 to 4 weeks to grow hair again.” If you use the method of shaving, the hair will grow again in ten days, and the hair will be very rough. Because the blunt edge of your hair is worn off during shaving, you will have a tingling feeling when your hair grows again. This discomfort will not exist when using the wax coating method. Scars are formed in hair follicles when pulling out hair, and the formation of scars will reduce the number of regrowth hair.
myth 6: skin cream can prevent or remove wrinkles
People who pay great attention to skin protection often spend a lot of energy choosing various skin care products to carefully care for their skin in order to keep their skin soft and smooth, but it seems that many of us do not know what is the best and most basic wrinkle prevention. The annual sales of face cream is as high as 250 million dollars, but does moisturizer really have anti wrinkle effect? Dermatologist Andrew kamber said: “skin creams can improve the appearance of skin, but they have no anti wrinkle effect.”
myth 7: reading in dim light will hurt eyes eyes
Will reading in a light deficient environment really hurt your eyes? Robert cotter, an associate professor of Ophthalmology at New York University, said that people often ask this question. In fact, this is wrong. He said: “will your ears be hurt when someone whispers to you? Of course not. Similarly, reading in a dark environment will not hurt your eyes.” When you stare at the TV or computer screen, will your muscles become tired and your eyesight be damaged? Kotter said: “it’s completely wrong. You will feel a little tired, but it will not damage your eyes anyway. But due to the specific structure of human eyes, people will become short-sighted, hyperopic or astigmatic. At this time, you need to correct your vision with glasses or contact lenses or laser surgery.”
myth 8: tight underwear damages men’s fertility
What are the similarities between tight underwear, notebook computer and hot bath? It is reported that all three will reduce the fertility of men, causing very serious consequences to those couples who want to have children. Dr. Harry Fiske, who treats male infertility, said: “the reason why testicles grow outside the human body is that they need to be cooled. If the temperature of the scrotum rises, it will have a negative impact on sperm production.” He was referring to the effect of wearing shorts on men, but there is no clear research result, so this is just a guess.
However, hot tub baths cause greater damage to male fertility. Fiske said that if the bath water is too hot, it will reduce the number of sperm. “In the next two months, the number of sperm will continue to decline. It will take 4 to 6 months for the number of sperm to return to normal,” Fiske said
myth 9: chocolate is not good for human health
Chocolate has always been regarded as the most typical fattening food. But the latest research shows that chocolate is also good for people. Cocoa beans are rich in a substance called flavonol, which can promote human health. Catherine Tamar degger, spokeswoman of the American Dietetic Association, said: “chocolate is very good for people’s heart. Chocolate has the effect of relaxing blood vessels. It may also have the effect of lowering blood pressure and reducing blood vessel obstruction. This effect is similar to aspirin and can reduce the incidence of heart disease.” Red wine, green tea, apple and onion also contain flavonols, which are high in cocoa beans. However, flavonols are removed in the process of making chocolate because they taste bitter and will affect the taste of chocolate.
myth 10: Revenge is sweet
Many studies show that hostility to others can have many negative effects. Ruskin said: “it is easy to cause people to suffer from heart disease and some stress-related diseases, and also increase blood pressure. The idea of harming others is like taking poison yourself, and eventually you will also be harmed.” After encountering misfortune, it is natural to have a revenge mentality. But from a psychological point of view, hatred is harmful to health. The beauty of hatred will seize people’s hearts and make them lose their vitality. Forgiveness is good for health. It can reduce depression, anger and stress. Ruskin said: “you may get a temporary pleasure after revenge, but forgiveness can heal the wounds of your life.”
