Is there a connection between excessive time spent on smartphones and social media and an increase in suicidal thoughts and depression among teens? A new study out this week says that could be the case, but the Tennessee Suicide Prevention Network says parents shouldn't rely on just that study -- based mainly on teen surveys.
The group says there are other things to look out for, including what your kids are looking at online, and how much time they're spending on their smartphones.
"If you notice your child, their appearance changes, if sleeping habits change or eating habits, if you notice their grades are changing, those might all be warning signs," said Scott Ridgeway with the Tennessee Suicide Prevention Network.
Experts say there are other warning signs to watch for if someone might be thinking about ending their life, including talking about feeling hopeless or having no purpose, talking about being a burden to others and increasing the use of alcohol or drugs. Here is a more comprehensive list.
