This is Hidden Brain.

Across the world, many countries are experiencing a sleep crisis.
In the United States, 50 to 70 million Americans have sleep disorders.
In India, almost 60% of adults get less than six hours of sleep every night.
Sleep deprivation can make us groggy and irritable.
Chronic sleep deprivation can rewire our brains and wear down our bodies.
It can change how we parent, how we work with others, even what we value.
This week on Hidden Brain and in a companion episode on Hidden Brain Plus, what happens
when a basic human need is jeopardized by an always-on culture and techniques to help you get a restful night of sleep?
Support for Hidden Brain comes from Instagram.
Instagram teen accounts' automatic protections limit who can contact teens, the content they can see,
and the time they spend on the app.
Teens are automatically placed into teen accounts.
Teens under 16 will need a parent's permission to change any of those settings to be less strict.
