Lack of sleep can make you ‘insensitive and selfish’, reveals study
A new study conducted by scientists at the University of California, Berkeley revealed that while lack of sleep causes mental and physical problems, it also affects a person’s behavior and especially feelings such as helping others or feeling the pain of others.
According to research published in the scientific journal Plus Biology, calm and quality sleep is not only related to human physical and mental health, but also affects social life.
Experts reviewed three different studies to examine the link between sleep and ‘numbness’, including one study that involved MRI scans of people’s brains.
In a study, experts reviewed data on donations made in US states between 2001 and 2016, in which they also looked at the personal information of those who made donations.
During the second study, experts divided the volunteers into two different groups and performed MRI scans of their brains.
Experts included people who slept for eight hours in one group and volunteers who suffered from sleep deprivation in another group and found that in people who had even one hour of sleep affected, the specific areas of the brain that people those who are sensitive and willing to help others were less active than those who slept soundly.
Similarly, in a third study, experts analyzed the data of 100 people who slept only a few hours after being awake for three to four nights, while some of them slept several hours a day but their sleep was not peaceful.
During the same study, experts found that restful sleep is better than restless sleep, which keeps specific parts of the human brain fully activated.
After reviewing the data from all three studies, the experts concluded that overall, lack of sleep makes a person ‘insensitive and selfish’, and they start to consider social issues and life, less important.
According to experts, lack of sleep has become a ‘global epidemic’ and this is the reason why we see social problems and tensions around the world.
Experts suggested that humans should have peaceful sleep to improve the society and understand the suffering of humanity.
