Early risers also tend to have better diets, eating less fast food and more fruits and vegetables. Night owls are more likely to put on weight due to their tendency to consume more calories late at night before bed.
And it doesn’t end there: night owls have a higher risk of depression, have worse quality of sleep, and consume more alcohol and tobacco than others.
Of course, waking up early won’t necessarily change any of these factors, but waking hours could be related.
