| Whether you have a morning or evening chronotype is dictated by your biological 24-hour clock. |
| It's much better to match people to schedules and structures based on their chronotype than to just force them into a schedule, knowing nothing. |
| For songbirds, early risers may have a greater chance of successfully producing offspring and passing along their chronotype to the next generation. |
| Previous research has indicated that there may be a significant relationship between chronotype and mood seasonality. |
| Changing your chronotype takes about two weeks, but you have to stick with it. |
| They selected their participants by chronotype, focussing on those who fell on either side of the Horne-Ostberg scale — those who preferred morning and those who preferred night. |
