You know those push notifications on your phone? They spike stress levels. We never know when one is coming, so we’re constantly in a state of hyper-vigilance. And the WORST push notifications are those from a text or email from work. According to the Future Work Center in London, an occupational psychology institute, seeing a work message on your own time takes you out of the moment and boosts psychological pressure. So kill those push notifications on your phone, otherwise you’ll walk around stressed 24/7.
