Lack of sleep prevents people from responding to positive information, study shows
Psychologists from the University of Rhode Island (USA) have discovered another negative consequence of constant sleep deprivation related to the emotional sphere of people's lives.
The respective study was published in the Journal of Sleep Research.
“Sleep deprivation has effects on all kinds of biological and psychological processes. As a clinical psychologist, I have always been most interested in how poor sleep affects emotions because this seems to be most directly relevant to mental health,” said study author Jared Minkel.
At the heart of the experiment were 16 film clips, curated for their validated emotional elicitation properties. These clips were categorized into positive, neutral, and mixed emotions, with scenes ranging from uplifting moments of joy and humor to everyday mundane activities, and even to complex scenarios that might evoke a blend of amusement and concern.
Participants viewed these clips in a sequence designed to prevent clustering of similar emotional stimuli, thereby minimizing the potential for emotional desensitization or bias in responses. This viewing took place in a controlled laboratory setting, designed to minimize distractions and standardize the testing environment across participants.
The researchers recorded various emotional reactions in the volunteers.
Tests have shown that when sleep deprived, people respond less to information that should evoke positive emotions. At the same time, the subjects perceived the videos with negative connotations as acutely as those who slept well.
Psychologists have come to the conclusion that chronic lack of sleep can deprive people of such positive emotional stimuli as joy and humor, leaving them alone with negative experiences. This can have a negative impact on a person's mental health and overall well-being.
Researchers recommend getting at least 7 to 8 hours of sleep as much as possible to maintain healthy emotional responses.
