Researchers from the John Hopkins University School of Medicine have recently conducted a new study on the best sleep conditions. They have, thus, found out that it is best to avoid sleep interruptions for a good disposition.
Many sleep studies were performed in the past and yet, we still can’t figure out what remedies to follow to get a good night sleep. Fortunately, researchers have gathered a group of 62 persons and asked them to take part in a controlled experiment.
The 62 persons were in a very good health condition and they belonged to different age categories, scientists have confirmed. According to their explanation, the participants were asked to sleep in three different setups.
The first night participants had to undergo forced awakenings, during the second night they went to sleep at a much later time and, finally, the third experiment allowed participants to rejoice uninterrupted sleep. The following days, participants were asked to fill out mood questionnaires, explaining how their mood changed based on the quality of the sleep.
Scientists have compared the pieces of information and discovered that people are much more high-spirited when they can avoid sleep interruptions. Patrick Finan, the lead author of the study, has added that bad mood is usually common among new parents, who experience many awakenings during the nighttime.
It appears that participants’ mood was significantly lowered when they suffered approximately eight awakenings per night. Similar results were observed when participants had delayed bedtimes. The majority of them had a very low disposition the following day.
Participants confessed that they felt much better when they had slept uninterruptedly. Finan has explained that their good disposition was mainly caused by their ability to go through all the sleep stages, including the “deep sleep” one. This is the most important stage because the entire activity of the brain and the body is slowed and people can truly recover. It goes without saying that people, who cannot reach the “deep sleep” stage, will feel very tired.
Finan has concluded, based on the new findings that the “deep sleep” stage is in direct correlation with people’s good mood. In his opinion, the sleep awakenings can be perceived as a different type of insomnia, because they produce more or less the same effects on participants.
In the future, he plans to recreate the same experiments on patients, who regularly suffer from insomnia. The future studies could help scientists find a better treatment for sleep conditions.
