A Czech study shows how well you sleep is more important than how long you sleep. The quality of sleep improves if you spend a lot of time in the sun and have as little contact with artificial light, the so-called “blue” light, at night. Exercising and not eating heavy food before going to bed also have a positive effect. “You should avoid working and studying in bed,” says study leader Michaela Kudrnácová from Charles University in Prague.
