It is said that deep sleep strengthens memory. But no one knows exactly how it happens. However, researchers now say that they have found physiological evidence from within the human brain that shows how sleep strengthens memory.

Researchers claim to have conducted brain studies that revealed a time during deep sleep when the brain becomes stronger. During this period, memory also becomes stronger. A closed-loop system was used to conduct the study. This system merges electrical pulses delivered in one part of the brain with stored memory in another part.

This finding could prove helpful for individuals suffering from memory-related disorders such as Alzheimer's and dementia.

The hippocampus and the cerebral cortex communicate with each other.

In research regarding how the brain transforms information into memory during sleep, it has been stated that the memory hub of the brain, known as the hippocampus, and the reasoning part, the cerebral cortex, engage in communication with each other during sleep. This occurs during deep sleep when the brain waves that emanate from the brain are extremely slow. During this time, neurons in different regions of the brain exchange information with each other.

For the first time, this study has provided insights into the mechanism of information exchange between neurons. It has also revealed that the memory hub takes information from the planning and reasoning regions during sleep and transforms it into memory.

Direct Connection between Sleep and Alzheimer's, 7.30 Hours of Sleep is Optimal

Previous research has revealed that a fragmented sleep pattern is associated with the development of Alzheimer's disease. Symptoms of Alzheimer's include memory loss, confusion, and delayed comprehension of new information.

Researchers suggest that if you are getting 8 hours of sleep and setting your alarm 30 minutes earlier, obtaining approximately 7.30 hours of sleep can have a positive impact on the brain. It reduces the risk of Alzheimer's disease, which is characterized by the loss of memory and forgetting things.

It is essential to practice these two techniques for deep sleep:

Control Screen Time

According to the Sleep Foundation, electronic devices such as cell phones and computers emit short-wavelength light. This blue light reduces the production of melatonin, the sleep-inducing hormone, especially during the evening. It also decreases slow waves and REM sleep.

Practice the 4-7-8 Breathing Technique

Find a comfortable position for this technique. Place the tip of your tongue against the roof of your mouth, right behind the upper front teeth. Exhale completely through your mouth, making a whooshing sound. Close your mouth and inhale quietly through your nose to a mental count of four. Hold your breath for a count of seven. Exhale completely through your mouth, making the whooshing sound, to a count of eight. Repeat this cycle three more times.
