    Study Links It to Improved Well-Being, Positive Behavioral Traits

    Hit the snooze button without guilt; those extra minutes of sleep may be good for your well-being, suggests a recent study. Researchers have found that sleeping an additional 46 minutes is linked to improved well-being and positive traits such as gratitude, flourishing, resilience, and prosocial behaviors.

    Even subtle changes in the amount of sleep can affect the components of your mental well-being, according to the latest study published in the Journal of Positive Psychology.

    Studies have shown that people with positive traits such as gratitude and resilience have better sleep. The researchers of the latest study investigated the reverse hypothesis, that is whether extra sleep helps improve positive behavioral traits.

    “This study is exciting because it expands what we know about the health effects of sleep restriction and extension to include variables related to forming flourishing moral communities,” Sarah Schnitker, a researcher of the study said in a news release.

    The researchers examined 90 young adults randomly assigned to three groups: sleep restriction, sleep extension, or normal sleep. The participants wore wristband actigraphy devices, which tracked sleep patterns, during the study sessions from Monday to Friday. The researchers measured participants’ levels of flourishing, resilience, and gratitude and noted improvements across the week with sleep extension and worsening levels with sleep restriction.

    “We saw that people who increased their sleep by 46 minutes a night ended up feeling more resilience, gratitude, life satisfaction, and purpose in life. When people were cut back on sleep by a mild average of 37 minutes a night, they experienced drops in mood, resilience, flourishing and gratitude,” Michael K. Scullin, principal investigator of the study said.

    The findings suggest that extra sleep not only boosts current moods and outlooks but has a far-reaching impact on overall well-being. The researchers also noted broader societal benefits, finding that sleep influences prosocial behaviors. Well-rested individuals had increased expressions of gratitude and a more positive outlook in social interactions.

    “It turns out that getting more sleep has a broader influence than just feeling more alert during the day. Better sleep helps you to have a clear vision for your life and to be more resilient to the challenges that could happen tomorrow,” Scullin explained.

  • Friend’s Genetic Traits Can Influence Your Mental Health Risk: Study

    Friend’s Genetic Traits Can Influence Your Mental Health Risk: Study

    Friendships during teen years can make or break mental health. It’s not just about the support they provide during tough times that the researchers are talking about, but how their genetic traits can affect you. The traits of your friends, particularly their genetic predisposition to mental health issues, can influence your mental health risks, a recent study revealed.

    Socio-genomics is a topic of growing interest that investigates the influence of a person’s genotype on the observable traits of another. The study published in the American Journal of Psychiatry investigated the peer’s social genetic effects and found that a person’s genetic predisposition to addiction, anxiety, and depression can have long-term consequences for their adolescent peers, affecting their risk of developing similar mental health issues later in life.

    “Peers’ genetic predispositions for psychiatric and substance use disorders are associated with an individual’s own risk of developing the same disorders in young adulthood,” said Jessica E. Salvatore, lead author of the study in a news release.

    “What our data exemplifies is the long reach of social genetic effects,” Salvatore said.

    The study was based on a database of more than 1.5 million people born in Sweden between 1980 and 1998. The researchers first mapped individuals by location and school during their teenage years. They then examined medical, pharmacy, and legal records to track substance use and mental health disorders into adulthood. Using models they tested if peers’ genetic risks predicted an individual’s risk of experiencing substance abuse, major depression, or anxiety. Peer genetic risks were assessed using family genetic risk scores for the same conditions.

    “Even when controlling for factors such as the target individuals’ own genetic predispositions and family socioeconomic factors, the researchers found a clear association between peers’ genetic predispositions and target individuals’ likelihood of developing a substance use or psychiatric disorder. The effects were stronger among school-based peers than geographically defined peers,” the news release stated.

    The researchers noted that these links were most noticeable among upper secondary school classmates, particularly those in the same vocational or college-preparatory track between ages 16 and 19. The peer’s genetic impact was greater for issues such as drug and alcohol use disorders compared to major depression and anxiety disorders.

    “The most obvious explanation for why peers’ genetic predispositions might be associated with our own well-being is the idea our peers’ genetic predispositions influence their phenotype, or the likelihood that peers are also affected by the disorder. But in our analysis, we found that peers’ genetic predispositions were associated with target individuals’ likelihood of disorder even after we statistically controlled for whether peers were affected or unaffected,” Salvatore said, adding that more research is needed to understand the mechanism.
