Since it's launch, Pokemon Go has encouraged people to get out and move in order to hatch eggs. There was some hope that the game's popularity would conincide with healthier life choices for people, especially Americans. When players go to Pokestops, they have the opportunity to get eggs. These eggs have set distances that users have to walk in order for them to hatch with sometimes rare Pokemon.
A recent study, Influence of Pokémon Go on Physical Activity: Study and Implications, has found that it was successful!
Many people increased their daily steps by 26% over 30 days, almost 1500 more steps per day than before they played. This is a significant increase that could make positive changes in health. In contrast, a control group actually walked 50 fewer steps during the same period. They have even proven to take more steps than they would wearing a fitness band. Overall, Pokémon Go has added a total of 144 billion steps to US physical activity.
Now that the game has become less popular, it isn't clear whether or not that trend will continue. Still, it is quite heartening to see that the game really did have a positive impact on society. Many of these steps were likely taken outside, so it was also getting people moving outside of their homes.
This was all in the United States, but with millions of people playing the game elsewhere, the numbers will only grow from there.
