Smartphones have become almost a necessity in our daily existence.

Whether we’re scrolling through Facebook, sending out a tweet, or taking a Snapchat, our phones are almost always by our sides — and as we move forward, younger and younger kids are starting to get their hands on these devices.

Having a smart device has many benefits, but for the younger generation, it’s causing some serious consequences. According to recent statistics by social psychologist Jean Twenge, “only 56% of high school seniors dated in 2015, compared to 85% for Gen Xers and Baby Boomers. The number of teens who spend daily time with friends dropped by 40% between 2000 and 2015.”

Adolescents with smartphones are also working less, going out less, having less sex, and depending more on their parents. All of these factors have lead younger generations to be “on the brink of the worst mental-health crisis in decades.”

Evidence has been linked through surveys suggest that increased screen time leads to lower levels of happiness, depression, and loneliness, considering social media often glamorizes others lives, causing younger people to be much more critical of their own. The result of all this leads to poorer social skills and recurrent depression later in adulthood.

With this information in mind, it’s important to evaluate screentime usage for younger kids in order to avoid some of these repercussions.
