A team of researchers from Ohio State University, USA, have created two different environments using mice as the elements for the experiment to study how it affects the stress social body's energy balance.
The first environment consisted of five or six members, living in typical laboratory conditions: comfortable, with plenty of water and food, but nothing more. The second one, three or four times larger, has the same food but has more space in which to move, where rodents may find several hobbies: wheels, tunnels, wooden toys, houses, material to their nests and a maze.
Evidently, it was the second environment where mice were more healthy and with less stress. Living surrounded by stimulus, with a large group and various activities result in more benefits than expected.
The increase in physical activity and avoid harmful effects of loneliness are positive aspects of a busy social life but it can provide something more valuable and surprising: an unexpected weapon against obesity.
