small things that seem insignificant may have a great impact on your health. The United States “Yahoo health network” recently published 10 small things that will shorten life in life. Compare them and see how many you account for?

1. Sedentary

this is bad news for office people. Even if you exercise regularly, sedentary is also harmful to your health. A study published in the British medical journal shows that sitting still for more than three hours a day reduces life expectancy by two years.

2. Too much sleep

too little sleep can damage health, but too much sleep is also harmful. A literature review on sleep shows that people who sleep more than nine hours a night have a 41% higher risk of heart disease than those who sleep seven to eight hours a night.

3. Staring at the screen for a long time

a research result published in the American Journal of Cardiology shows that people who stare at the screen (such as watching TV, Internet or mobile phone) for more than 4 hours a day will increase the risk of heart attack and stroke by 113%. Another study showed that reducing the time spent staring at the screen to less than two hours a day would increase life expectancy by 1.4 years.

4. Taking some drugs for a long time

taking drugs for insomnia and anxiety will shorten people’s life expectancy. A 12-year follow-up survey published in the Canadian Journal of psychiatry showed that people who did not take these drugs had a 5% lower mortality rate than those who took them.

5. No humor

the research of Mayo Clinic in the United States shows that laughter has many benefits to human health. It can enhance the function of immune system, reduce stress, provide channels for emotional release, and laugh can also burn human calories.

6. Long commute time

a study presented at the annual meeting of the American Federation of geographers shows that people who commute for more than 30 minutes die earlier than others. Long distance commuting means less exercise and less sleep, both of which help people live healthier and longer.

7. Excessive pressure

a research result published in the Journal of the National Academy of Sciences shows that stress damages people’s DNA. Compared with people without stress, participants in chronic stress had shorter telomeres, a region responsible for protecting the ends of DNA strands so that DNA would not decompose and degenerate.

8. Scholars from Duke University in the United States found that women with pleasant sexual life can live nearly 8 years longer. Another study published in the British Medical Journal showed that men who had sex more often had a 50% reduction in mortality.

9. Eating too much red meat

processed food, too much red meat and insufficient amount of fresh fruits and vegetables will all cause serious health hazards. A study published in the Journal of internal medicine showed that red meat consumption was high, and incidence rate of cardiovascular disease and cancer mortality were high.

10. Not sociable

the negative impact of loneliness and loneliness on the human body is equivalent to excessive stress. The report “successful aging” submitted by Mike Arthur Research Institute in the United States shows that people who think they are very valuable in friends and family life may live longer.
