It’s not just alcohol and the nightlife that are causing people to lose concentration on work and become soulless zombies the next day. A phenomenon called smartphone “hangover” apparently also exists, according to a study.
After surveying a variety of US workers, Russell Johnson of Michigan State University discovered a correlation between late night smartphone usage and decreased productivity. Whether it’s for composing a business-related email or just the leisurely playing of Candy Crush, Clash of Clans, or Plants vs Zombies 2, using smartphones at night translates to a hangover the next day.
The study also found that smartphones bring about a more harmful effect than other night activities, such as watching television and using the PC/tablet. Smartphones also have that “blue light” emission that is detrimental to the production of melatonin, a hormone relevant to regulating the sleeping cycle.
So instead of cramming in more work at night, just sleep and rejuvenate.
