Depression and suicidal thoughts have doubled in young Americans, according to a new study from the American Psychological Association.
Likely triggers? Cell phones and social media.
"More US adolescents and young adults in the late 2010s, vs the mid-2000s, experienced serious psychological distress, major depression and more attempted suicide (自杀)", says lead researcher Jean Twenge, professor of psychology at San Diego State University. "These trends are weak or non-existent among adults 26 years and over, suggesting a generational shift in mood disorders instead of an overall increase across all ages."
Twenge believes this trend is partially due to the explosion of digital culture over the past decade, which may have twisted modes of social interaction enough to affect mood disorders.
The study analyzed data from the National Survey on Drug Use and Health, which tracked drug and alcohol use and mental health issues in more than 200,000 youths aged 12 to 17 from 2005 to 2017 and almost 400,000 adults from 2008 to 2017.
Major depression in the last 12 months increased by 52 percent in kids from 2005 to 2017 and 63 percent in young adults aged 18 to 25 from 2009 to 2017. There was also a 71 percent jump in young adults experiencing serious psychological distress in the previous 30 days from 2008 to 2017.
So what's so different now? Twenge says research shows young people just aren't getting as much shuteye as they did in previous generations.
Whereas older Americans might have established more stability in their lives, sleep-disrupting social stressors are likely at their peak for teens and young adults in this digital era, she says. Older adults are also less likely to let devices interfere (干预) with sleep.
These results suggest a need for more research to understand how digital communication versus face-to-face social interaction influences mood disorders and to develop specialized interventions for younger age groups.
Her suggestion? Put your phone down at least an hour before bedtime.
Climbing Without Ropes
The popular image of the mountain climber is of a person carefully climbing a steep cliff with a network of safety ropes, but it is not the only kind. Many climbers now enjoy bouldering. It's more accessible and better for the environment.
What is bouldering? Bouldering is a sport that involves climbing on, over, and around boulders up to approximately twenty feet above the ground. Participants employ no safety ropes. | ||
Why boulder? •improve your climbing skills by focusing on basics •places to climb, such as climbing walls at gyms and parks, easy to find •less time commitment to bouldering than to mountain climbing •intellectual and physical enjoyment as one solves problems | Bouldering Terms crimp: a very small handhold foothold: a place where one may place a foot to aid in climbing boulder jug: a very large handhold that is easy to use problem: The path up a boulder is referred to as the “problem” that one must solve. The “solution” is the sequence of moves one makes up and over a boulder. |
Here is an example of a climber addressing a bouldering problem.
Figure 1: The climber has two routes she could take, one to the left and one to the right. The left one appears easier because it has a jug within easy reach, but look what happens if she chooses that direction. She gets stuck on the rock and has to go back down. Sometimes that is even difficult than going up.
Figure 2: The climber takes the one to the right this time. using a foothold and placing her right hand in a crimp, she is able to life herself up and locate other handholds. After only a few moves, she is able to throw her leg over the top of the boulder and pull herself up.
