Social media and traditional media have the effect of a direct pipeline to the brain.

In the 1940s, newspapers delivered the news once a day morning or evening.  Photojournalism was reserved for the movie theater well after the events happened.  In the TV age of the 1960s footage of the Vietnam war was flown back to the U.S. in time for the evening news.  Around 2000 you could use a computer to search for news.  Now news that is often anxiety producing is delivered constantly on digital devices.  To manage anxiety, it now means managing the flow of necessary news.  The technology is 24/7 but you schedule the delivery that is least stressful.
