Insomnia is a problem facedmany people. It is not only chronic, as many believe. Sleep disorders can occur after severe stress, and it can occur both against the background of negative emotions and positive ones. Surely many of you have come across a situation where you could not fall asleep before any important event or important event for you. Many people try to get rid of insomnia with the help of drugs, but they usually harm the healthy, have contraindications and a number of serious side effects. However, according to scientists, there is another effective way to fall asleep quickly. It does not require medication, but, what is most interesting, it is used by various animals, including cats, dogs and even mice. If you watch these animals, you will see how they prepare for bed.
Effective remedy for insomnia
If you have a cat or dog at home, youyou probably noticed how the animal performs the same ritual before going to bed - straightens its place, walks in a circle and bridges for a long time before lying down, licks its paws, etc. According to scientists at the University of Michigan in Current Biology, these actions help animals sleep. Of course, this does not mean at all that people also need to bridge and repeat other actions after animals before going to bed.
The process of getting ready for bed matters,that is, a routine that must be carried out in front of him day after day. For example, people usually make the bed, brush their teeth, set the alarm, and so on. If these actions are performed regularly before going to bed, and become a habit, in the process of their implementation, the brain receives the appropriate signal, and begins to prepare for sleep in advance. As a result, it helps to fall asleep easier and also improves the quality of sleep itself.
How does a bedtime ritual help you fall asleep?
That doing the same thingshelps to sleep, has been known for a long time, but a causal relationship has not been established. To remedy the situation, employees of the University of Michigan conducted an experiment on mice. These rodents usually make a nest before going to bed, in which they subsequently lie down.
The researchers decided to track the activityanimal brain neurons during this ritual. As a result, they found that neurons in the lateral hypothalamus are activated during the creation of the sleeping nest in mice. This is a region located in the forebrain that is responsible for hunger, fear, thirst, and other behaviors. In particular, the lateral hypothalamus controls sleep intensity.
To ensure that the conclusions drawn are correct,scientists began to prevent mice from creating a nest for themselves before going to bed. As a result, they noticed that the rodents took longer to fall asleep. Moreover, the sleep quality of animals that did not prepare for sleep was markedly reduced.
To draw final conclusions, the researchers decidedartificially suppress neurons that were active at the time the nest was created. This caused the mice to stop preparing for sleep. At the same time, they could not fall asleep for a long time and did not sleep well. It follows that the neurons that are responsible for the “pre-sleep” routine really help to fall asleep.
Scientists may create new cures for insomnia
The research carried out is of great importanceto fight insomnia. Everyone can take note of the results of the work, and always perform certain actions before going to bed, even when there is no strength for the routine. But its main value is not even in this.

Knowing which neurons are responsible for falling asleep andsleep intensity, scientists will be able to influence them artificially with the help of drugs. It is possible that new drugs will not only be more effective than existing ones, but also safer.
“Understanding the neural mechanism that facilitatesthe natural transition from wakefulness to sleep can make a big difference for many people with insomnia,” says Ada Eban-Rothschild, associate professor of psychology and neuroscience, senior author of the study.
Finally, let me remind you that normal healthy sleepextremely important for the body. In one study, scientists found that lack of sleep speeds up the aging process. That is, the biological age of a person increases. However, contrary to popular belief, it is needed not only for the brain. The latter continues to work actively during sleep, unlike many other parts of the body.
