Exercise is known to benefit people’s mental health, but scientists recently discovered that too much exercise may have a negative effect on it.
The researchers studied about 1.2 million people in the United States in 2013, 2015 and 2017. The participants, on average, experienced 3, 4 days of poor mental health each month. Those who did exercise experienced 1, 5 fewer days of poor mental health per month, compared to those who didn’t exercise at all. The team found that people who exercised for 30 to 60 minutes three to five times a week had the best mental health, but those who exercised for more than three hours had worse mental health than those who didn’t exercise at all.
The scientists think that people who exercise so much may experience poorer mental health because that much exercise can be a sign of obsessive (强迫症患者) behaviors that have been associated with poor emotional and psychological outcomes. However, the only mental health disorder that the researchers looked at was depression.
Among those who had been diagnosed with depression, people who did exercise experienced 3.75 fewer negative mental health days than those who did not, showing an ever greater difference, According to the Centers for Disease Control and Prevention. 7, 6 percent of people in the U.S. age 12 and over have depression. While all types of exercise appeared to help with mental health, cycling, gym-based exercise and team sports were the most beneficial.
The team also looked at more specific factors, like education. People with a college education reported 17.8 percent fewer days of poor mental health than those without that level education Additionally, people in a healthy BMI (体重指数) range reported a 4 percent reduction in poor mental health days thin those whose BMIs were high. Even salary was a factor: compared to people with bower salaries, those with higher salaries experienced a 17 percent reduction in poor mental health days.
The study showed that exercise can help with mental health, but that in some cases, limiting it may be necessary.

Two years ago, something happened that changed the way I look at the world. On my birthday, my grandfather, walking home with his hands full of groceries, fell and hit his head on the sidewalk. Just as we were leaving to meet him for dinner, we got the call that he was in the hospital. At first, I thought nothing of it, but when I heard the whole story, I couldn’t believe it. He hit his head so hard that he had a blood clot in his brain and it had to be operated on immediately, Everyone thought he would die.
Although my grandfather survived emergency brain surgery, he had complications (后遗症). He could hardly talk and he couldn’t walk. Shortly after, he was admitted to a nursing home. Today, he lives at home with my grandmother and is doing much better, but this isn’t about him. It’s about what I saw at that nursing home.
I saw something that many people haven’t seen, and some do often choose to ignore it, I saw more sadness in those days visiting the nursing home than I thought. In that one place were hundreds of old people who were alone and forgotten.
So what as to be done with the situation of the old? This is not an easy question, but something must be done. Perhaps groups in the community could assign each member to one nursing home patient with whom they could keep in regular contact. Maybe a school could focus on a nursing home and send cards, pictures and letters to residents. If periodic visits were arranged, I’m sure that for some, if not many, those students would be the only visitors they had all month. These are just a few ideas; we all need to work together.
I hope everyone to tour a local nursing home I further expect you to do something about it. You’ll brighten someone’s day, or maybe even his or her life.

For thousands of young people everywhere，college means taking their first big step into adult life. What you do in your first year of college can have a big effect on the rest of your college years. Here are some tips of mine for you.
Plan ahead. By the end of your first week, you'll know when you should finish each of your study tasks. Put those on your list. More importantly, you need to finish them on time. Start making good use of your time at the beginning of the term.
Eat right. College students often gain weight in their first year. Without Mom and Dad planning your meals, it's easy to lose track of just how many calories you’re taking in. Try to limit fast food and keep a varied diet.
Talk to your professors. College students tend to be afraid of their professors. Don't be afraid. They're there to help you. Visit a professor during his or her office hours just to chat with him or her. Tell them about a book you have read，or ask for advice. And, of course, ask for help, whether with a difficult point in your readings or with big life issues (问题).If nothing of these, a professor can point you in the right direction to find the resources you need.
Speak up in class. Ask questions, answer the professor’s questions, and share your opinion as much as possible. There are no points for sitting quietly anymore.
Go to the library. There are so many resources available in the library-- magazines, videos, and of course, the books you need for your papers. Learn as much as you can about your library .Talk with the librarians about the resources available in your field.
