If you're into zodiac signs, personality types or eating right for your blood type, I've got great news for you.
Sleep Animals are a brand new way to categorize yourself based on your sleeping patterns.
Ever wonder why some people seem to have a God-given ability to wake up without three alarm clocks, or why you can't think straight until 3 pm, no matter how much caffeine you've had?
Well, according to the Sleep Animals chart, you might be a wolf.
Dr. Micheal Breus, aka "The Sleep Doctor," claims there are four types of sleepers: dolphins, lions, bears and wolves. Each type is categorized based on the pattern of sleep that's most natural for them.
Here are the different types of sleep animals, the nocturnal habits that define them, and how to work with your type for a better night's rest and, consequently, a more productive day.
Dolphins are light sleepers, and have a tendency toward insomnia because they're highly-intelligent people who have a hard time turning their brains off.
Dolphins are the rarest type of sleep animal, accounting for only 10 percent of the population. Light sleepers, they wake at the smallest noise to alert others of any present danger.
For maximum efficiency, dolphins should start their day with a workout around 6:30 am. They need to eat breakfast about an hour after waking up and they do their best work between 10 am and 12 pm.
It's also suggested that dolphins take a brisk walk before dedicating themselves to intellectually-challenging work in the afternoon, and that they go to sleep around 11:30 pm after an hour of no phone, computer or TV screens.
Lions wake up early, full of energy and drive, but by early evening, their energy takes a nosedive and they're ready to drop dead.
If you think you're a lion type, a good bet is to wake up at about 5:30 am and do any daily planning about an hour and a half after waking up.
Schedule your daily meetings between the hours of 10 am and 12 pm.
The afternoon should be dedicated to more independent work, so if you're writing the next great American novel, do it between 2 pm and 4 pm.
The best time to exercise for lion types is around 5 pm, and bedtime should be around 10 pm.
Bears have a high sleep drive and need a full eight hours of sleep every night. They take their sleep cues from the sunrise and sunset.
If you can relate, you should be aiming for a 7 am wake up, and a short, simple workout. Bear types should save their most difficult work tasks for the hours between 10 am and 12 pm.
Because bear types get tired at sunset, it's best for them to try to get a nap in the afternoon if it's manageable. If naps aren't possible, then even a few moments of rest or meditation could do them some good.
Any creative brainstorming should happen between 8 pm and 10 pm when their minds are wandering into sleep mode, and they should be aiming for bed at 11 pm.
If you need several alarm clocks to wake up, are still groggy around noon but really hit your stride during late afternoon, you're undoubtedly a wolf.
Wolves should try to wake up using two alarms around 7 am, and do some outdoor exercise to shake the dust from their eyelids. It's also beneficial for them to eat as soon as they wake up to boost their energy.
Lunch should be around 1 pm, and the afternoon should be dedicated to any creative endeavors. Bedtime for wolf-types should be later than usual, around 12 am, as wolves don't get tired before then anyway.
