Good news for those who are neither a night owl or an early riser, a new study from the Russian Academy of Sciences has found there are two additional, common sleep types that may be more suited to your sleeping habits.
Early attempts at sleep science have encouraged people to put themselves into two different types of sleep categories depending on when they are most productive.
There are the night owls, who like to stay up late into the night to get work done, or the early risers, who want to make the most of the daytime hours. An interesting new study conducted by biologist Arcady Putilov, with the help of the Russian Academy of Sciences, asked 130 people to stay awake for 24 hours. The subjects were then asked to fill out a questionnaire about how awake they felt, their sleep patterns and how well they had been functioning the week before.
Out of the 130 people, 29 were early risers, who showed higher energy at 9am than at 9pm, and 44 night owls who were the opposite. But what was most interesting was that there was a group of 25 people who reported feeling relatively spritely both the morning and the evening and 32 others who felt lethargic during those times. Both the lethargic and energetic participants went to bed and woke up somewhere between the night owls and early riser times.
