For years people have thought there were two types of sleepers, early risers and late risers, But now researchers from the Siberian Branch of Russian Academy of Sciences have two new types to add to the mix.

So maybe there's a new category of sleeper that you'll find you fit perfectly in.

    Early Risers

    If you enjoy getting up and starting your day, you probably identify with the early risers. Research shows these individuals prefer to go to bed early and wake up early and are have the most energy from 9 a.m to 9 p.m.

    Late Risers

    On the flip side of that is the late riser. Sleeping in and staying up late to get things done are characteristics of this type of sleeper and they have a very hard time getting going early in the morning, Instead late risers find they are most productive from 9 p.m. to 9 a.m.

    High Energy

    New research shows there are people out there that have energy all day, every day. Dubbed high energy, these folks can survive on 30 minutes less sleep than most people need and still feel sprightly in the morning and night.

    Always Tired

    Last but not least are the always tired sleepers. The folks who not matter how much shut eye they get never really feel like they're ready to go. These sleepers are ready to nap at all times and usually feel lethargic throughout the day.
