The personslity ranged peraonality age from 18 to 32 and included slightly more women than men. So where do these differences between night owls and early birds stem from? There are two possible explanations, the researchers said.
One is that people's genes play a role in determining their circadian rhythm -- the inner clock that regulates sleep and other physiological processes. Study author Ana Adan at the University of Barcelona told CBS News in an email that "several studies have linked different circadian rhythm genes with the development of mood disorders, schizophrenia and drug consumption.
Another possible explanation is related to so-called "social jet lag," which is a term used to describe the lack of synchronization which can occur between a person's biological clock and the society around them, Adan said.
And if evening types struggle to adapt to this kind of schedule, they may develop symptoms of depression and anxietyAdan said. Evening-type men in the study were more likely to suffer from mental disorders than evening-type women, which surprised the researchers, Adan said.
This was unexpected, as women generally tend to be more vulnerable "to the development of depressive and anxiety symptoms than men," Adan said. However, it seems that there might also be some more positive aspects of being a night owl. Argelinda Baroni, an assistant professor of child and adolescent psychiatry at the Child Study Center at NYU Langone Medical Center, told CBS News.
Baroni, who was not involved in the study, also pointed out that "eveningness" is more common in the age group that the researchers used in the study, especially among males. It would be interesting to see whether the people's sleeping patterns and personality traits would change with age, as "eveningness" tends to decrease when people get older, she said.
Overall, she said, "I think it is a study that is consistent with other research," on differences between morning and evening types. For instance, other research has found that adults with ADHD indeed tend to be night owls, as shown by their sleep-wake schedules and their levels of melatonin, a sleep-regulating hormone, she said.
Adan said that the new findings may be helpful to healthcare professionals who could use them to develop new and more accurate therapies for the treatment of different disorders affecting people with different circadian rhythm patterns.
The new findings are being published in the October issue of the journal Personality and Individual Differences. Thanks for reading CBS NEWS. Please enter email address to continue. Please enter valid email address to continue.

Morning types are also more resistant to fatigue, frustration and difficulties, which often translates into lower levels of anxiety and lower rates of depression, higher life satisfaction and less likelihood of substance abuse.

They also appear to be more likely to develop addictive behaviors, mental disorders and antisocial tendencies, and even to attempt suicide.

Although research on chronotypes is still evolving, one recent survey suggests that there may be distinct afternoon and napper chronotypes as well, when alertness peaks in the afternoon or before and after 3pm. Older adults tend to have more trouble sleeping , including falling asleep, staying asleep, and remaining alert throughout the day. Research suggests that this may be because the brain area responsible for the circadian clock shows weaker electrical activity as we age, sending muffled messages to the rest of the body. An individual's biological clock can be set earlier or later, but keeping cues that influence circadian rhythm steady can help everyone maintain their routine. Waking up and going to sleep at the same time each day—and exposing oneself to sunlight and darkness at those times—supports steady melatonin production. Avoiding screens in the evening is therefore an important change that can benefit those hoping for better sleep. Sometimes these changes are outside of one's control, as in the case of travel. Jet lag occurs when the internal clock and external cues become misaligned, which can result in fatigue or irritability before the two forces realign. Most people can reset their body clock by keeping a regular schedule and exposing themselves to natural light in the morning. But if you have Delayed Sleep Phase Disorder, you may want to explore melatonin, chronotherapy, or bright light therapy. Decrease the brightness of screens at all times, and keep screens out of the bedroom altogether. Increase your exposure to sunlight and nature, incorporate more exercise into your day, and maintain a regular routine. These tips and others can offset the chance that screens disrupt your circadian rhythms. The basics of sleep hygiene include creating a bedtime routine, making sure the bedroom is cool and dark, avoiding caffeine from the afternoon onward, and avoiding screens an hour before bed. It may also be helpful to take a 20 minute nap between 12pm and 3pm, and to focus on getting enough weekly sleep rather than nightly sleep. When you wake up, get out of bed rather than snoozing the alarm and beginning a new sleep cycle. Provide your brain with fuel by eating breakfast. Go outside within two hours of waking up to expose yourself to natural light. Read a full hour-by-hour guide on how to best structure your day here.
