Many people lie awake at night, worrying about something from their job to the future. Now, researchers have discovered a simple and cheap solution: going to bed earlier. What time a person goes to bed and how much they sleep affects how much they worry, according to a new study.

Researchers found people who go to bed later, or sleep less, have pessimistic thoughts that seem to repeat in their minds, which they feel unable to control.

They also tend to worry excessively about the future, look back too much on the past, and experience annoying thoughts, mirroring the symptoms of people with anxiety and depression.

Regular lack of sleep might actually be linked to the development of anxiety, the researchers concluded.

The findings, coming after a number of studies, suggested getting between seven and eight hours sleep which is essential for good health. Less than this is thought to increase the risk of a person becoming fat, depressed, and can even cause severe health problems such as cancer and heart disease, because it upsets the body clock.

As part of the new study, researchers asked 100 young adults at Binghamton University to complete questionnaires and two tasks on computer. These measured how much the students worried about something. They were also asked if they were more of a "morning" or an "evening" person.

The researchers found that people who sleep for shorter periods of time--and go to bed later--often experience more negative thoughts than others. This was also true for those students who described themselves as evening types.

Jacob Nota, of Binghamton University, who carried out the research, said, "Making sure that sleep is obtained during the right time of the day may be an inexpensive and easy solution for individuals who are both bothered by negative thoughts".
