What does computer hertz mean?

  Hertz is the unit to calculate the frequency, and it is the refresh frequency of the screen displayed by the computer. It is generally set to 60Hz, but at present, due to the needs of games, there are already 144Hz or even 240Hz display screens; This parameter refers to how many pictures can be displayed on the display screen in one second, and 60Hz refers to displaying 60 pictures in one second. The details are as follows:

  1. It refers to the refresh frequency of computer screen, which needs to be set according to your monitor parameters, generally set to 60Hz. At present, many e-sports game monitors have supported the refresh rate of 144Hz or even 240Hz.

  2. Because the dynamic picture of the display screen is displayed by refreshing, it is not easy for human eyes to recognize because of the high refreshing frequency. The refresh rate refers to how many pictures the display screen can display in one second, and 60Hz refers to displaying 60 pictures in one second. The higher the refresh rate, the smoother the dynamic picture display.

  3. However, the refresh rate needs the support of graphics card and monitor. If you need to choose a refresh rate above 60Hz, you need to ensure that your monitor supports high refresh rate.

Winter is also the fitness season.

  "Cold winter" is the coldest season of the year. As the saying goes, "La Qi La Ba, frozen chin", the twelfth lunar month is in the cold winter. At this time, proper physical exercise and proper health care can not only relieve fatigue, but also make the body healthier.

  Exercise in winter is essential.

  Every winter, the winter swimming area of Nanhu Park in Changchun, Jilin Province is very lively, and there are often winter swimmers who are full of energy and swim in the "ice and snow".

  Wu Zhaorui, an 88-year-old, has participated in winter swimming for more than 20 years. "Come every day, we don’t catch a cold, we don’t fear the cold, and we still swim in winter." Speaking of winter swimming, he seems very confident.

  "Scientific winter swimming brings physical, life and spiritual benefits to winter swimmers, and the benefits of winter swimming have been recognized and accepted by more and more people." Mr. Ma, a winter swimmer in Hubei, talks about winter swimming with a clear head. "Winter swimming is very particular. To talk about science, every minute is the key. According to each person’s physical fitness, we should properly master the swimming volume."

  In fact, besides winter swimming, there are many sports suitable for winter. According to health experts, aerobic exercise with smaller movement range and higher calorie consumption should be selected for winter exercise. Weibo, the official of People’s Daily, once counted nine sports suitable for winter, including skipping rope, jogging, climbing stairs, Tai Ji Chuan, alternating running, badminton, swimming, cycling and walking.

  In addition, the passionate ice and snow sports have become the winter exercise items for more and more people. In recent years, ice and snow sports are heating up all over the country, and skating and skiing have become a winter carnival for many people.

  Winter sports have many benefits.

  There is a folk saying in China: "If you move in winter, you will have less illness;" Be lazy in winter and drink a bowl of medicine. " Proper participation in sports in winter is self-evident.

  According to health experts, winter exercise can speed up the body’s metabolism. When the body is stimulated by cold, it will increase the antibodies against diseases in the blood, and the body’s resistance to diseases will also increase. Therefore, people who insist on exercising in winter are less likely to suffer from diseases such as colds, bronchitis and pneumonia.

  There are many benefits of winter sports. For office workers, winter exercise can speed up blood circulation, increase the supply of oxygen to the brain and enhance the elasticity of blood vessels. This can eliminate the fatigue of the brain caused by long-term work and improve work efficiency; For the elderly, outdoor exercise in winter can fully enjoy the sunshine, promote the body’s absorption of calcium, and effectively prevent osteoporosis; For bodybuilders, when the warm body touches cold air or inhales cold air, the calories burned by exercise will increase slightly, so the effect of losing weight in winter exercise is better.

  Of course, although there are many benefits of exercising in winter, we should pay attention to some problems. "In winter, the weather is cold. Generally speaking, it is best to exercise when the cold gradually fades after sunrise." Dr. Theway, from the Massage Department of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, said, "We should pay attention to minimizing outdoor sports in foggy days."

  Pay attention to health in winter

  Chinese medicine pays attention to "spring life, long summer, autumn harvest and winter storage". "Winter is March, which is called hiding". Winter is the season when vitality lurks and everything stings and hides. Li Yanling, director of the Nutrition Department of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, pointed out that the purpose of beginning of winter’s tonic is to preserve the yang of the human body, keep the body warm, nourish yin and subdue yang. Nursing should be combined with food supplement and medicine supplement, with warm supplement and flat supplement as appropriate. You can choose chicken, mutton, pears, chestnuts and other foods, and eat more foods containing inorganic salts such as potassium, sodium and calcium.

  Pay more attention to hydration in winter health. Dr. Li from Changchun Hospital of Traditional Chinese Medicine said that the warm room in winter will be drier and people will lose more water. Being in such an environment for a long time, the body is naturally prone to dehydration. At the same time, Dr. Li pointed out that the most important thing in winter health care is to go to bed early. Adequate sleep should be ensured in winter health preservation, which is beneficial to the hidden yang and the accumulation of yin and body fluid.

  Winter is a season suitable for "tonic", but "tonic" depends not only on eating, but also on moxibustion. Jin Xiaoqing, chief physician of acupuncture department of Zhejiang Hospital, said that when the cold current comes in winter, some people with weak body can play a role in cold resistance and health care through warm "winter moxibustion", that is, moxibustion.
