Here’s what happens to your brain when you don’t get enough sleep


UCLA recently carried out a new study said to be first of its kind which revealed that “lack of sleep destroys brain cells” and their capacity to communicate. At the point when your nerve cell wires are crossed, you sometimes feel spaced out. Or, forget little things quickly.

“We found that depriving the body of sleep denies neurons of the ability to work well,” said Itzhak Fried, study author, and neurosurgeon. “This results in cognitive slip by the way we see and respond to our general surroundings.”

Dr. Fried and his team of researchers studied 12 individuals for the surgery at UCLA for epilepsy. Before the surgery, electrodes were implanted in the brains of the subjects to pinpoint the cause of their seizures. Since the absence of sleep can incite seizures, subjects remain conscious throughout the night to speed the start of their episode and reduce their stay in the hospital.

The electrodes also recorded the firing that occurred in the brain cell as scientists got some information from the subjects about a range of pictures. As the patients become fatigued, brain-cell firing reduced. Too little shuteye meddled with the neurons’ capacity to encode data and make an interpretation of visual inputs into a cognizant idea.

Sleep deprivation linked to depression and chronic diseases

“Lack of sleep dampened the activities of the brain cells,” said one of the researchers Yuval Nir of Tel Aviv University. “Unlike the typical quick response, the neurons reacted gradually and fired weakly, and their transmissions delayed a bit longer than normal.”

While the UCLA scientists didn’t recommend a reasonable amount of sleep, the National Institutes of Health and few other medical organizations suggest between 7 to 9 hours of rest every night for an adult. Further investigation is required to deeply understand the many benefits of adequate sleep, as well as the lack of it, which has been connected to anxiety, depression, cancer, obesity, stroke, Alzheimer’s, diabetes, and heart attack. However, the UCLA team says the investigation can have great impact.
