There are many pre-sleeping routines that have been advised by numerous professionals and health studies in the past. But through the limited understanding we have about the neurological factors of sleep, solutions for problems revolving around it, including insomnia, are still unavailable.
Pre-Sleep Routines for a Good Night's Sleep
Pre-sleep routines of animals were already discussed in several papers before, but the data in humans are not yet explored thoroughly. In a new study, the neurobiological mechanisms that are responsible for pre-bedtime activities might have been discovered.
The research was led by scholars from the University of Michigan. In their paper, the authors analyzed a series of mouse experiments to determine how the brain works before we sleep. The findings collected from this research present new insights over brain regions that are inducing the pre-sleep pattern of people.
The authors elaborated on the puzzles of sleep, including how animals transition to being awake, how the brain interacts and responds to the environment upon wakefulness, as well as the distinct oscillatory patterns during sleep.
The experiments for pre-sleep analysis were made possible through the help of mice. Each of the subjects had their neural activity for 20 minutes prior to their sleep. Through the investigation, the experts identified how the onset of sleep is linked to pre-sleep behaviors. In addition, the exact regions of the organ that induces the activity were located.
The lateral hypothalamus is a part of the brain res[pnsible for many processes in the human system. In the study, the lateral hypothalamus was observed to hold most of the brain cells, or neurons, that work for general arousal and feeding behaviors.
According to the study, the predominant and wide-scale projection of the glutamatergic neuronal ensembles in the lateral hypothalamus initiates the pre-sleep nest-building behaviors as well as the intensity of the sleep.

Brain Cells in Lateral Hypothalamus May Answer How to Get Better Sleeping Experience
The neuronal ensembles gathered in the lateral hypothalamus are found working together with other brain cells across other sleep-regulating regions. In conclusion, pre-sleep behaviors are essential to keep the brain regions activated when they shift during sleep and waking up.
Through the activity of brain cells involved in neurological activities prior to sleep, the authors said that a novel approach for sleep therapies could be developed. Further research over this little moment before bedtime can give us clues on how to prepare for a better and healthier sleep experience, as well as to solve crippling conditions such as insomnia.
The critical insights collected from the study serve as an advancement to our current knowledge regarding the neurobiological mechanisms for controlling sleep-related and goal-directed behaviors, the authors emphasized.
Ten to thirty percent of the global population experiences issues on maintaining and even initiating sleep. The current treatments, although effective at certain levels, have their own share of downsides to the health of patients. Therefore, understanding how the process of sleep and pre-sleep regulations could help us improve our resting schedules, as well as our quality of life.
The study was published in the journal Current Biology, titled "Lateral hypothalamic neuronal ensembles regulate pre-sleep nest-building behavior."
