The relevant hashtag (标签) “brittle college students” has recently exploded on social media. It has been used by netizens to jokingly describe how easily college students can get injured and sick. According to reports, Zhengzhou Central Hospital received some 1,700 young people aged between 18 and 25 in its emergency department in September alone. “Most cases were caused by irregular daily routine, staying up late and unhealthy diet,” said Cheng Xiaodan, deputy director of the hospital’s emergency department.

In addition to insufficient exercise, the rising number of “vulnerable college students” can be attributed to irregular work and rest schedules and unhealthy lifestyles, according to Gou Bo, professor of sports medicine at Xi’an Physical Education University. “Nowadays, college students spend too much time on smartphones with lots of sedentary screen time. Many stay up late playing games or writing essays, etc., which leads to waking up late and skipping breakfast. All of this harms physical health, resulting in a more ‘brittle’ body,” Gou noted. How can college students build themselves up? Here are some suggestions:

▲Make sure you get 8-10hrs sleep each night to reduce anxiety levels, and clean out toxins that build up in your brain.

▲Find a healthy interest you get excited about — whether sport, hobby or other activity — and add it into your schedule. Set yourself some short and long term goals and go for it!

▲Start simple and do some research on areas you can improve like — drinking more water, reducing processed foods, eating more fruits and vegetables, and staying away from added sugar!

▲Whether you can set a realistic goal like 10,000 steps per day or choose an activity that you enjoy, plan out your week to ensure exercise is one of your main priorities.

▲Too much screen time can reduce the quality of sleep and raise the risk of developing attention problems, anxiety and depression.
