Published in the International Journal of Environmental Research and Public Health, researchers found that problematic smartphone use is linked with low self-esteem as well as negative cognitive outcomes. Scientists are working to understand how exactly a COVID infection affects the human brain. But this is difficult to study, because we can’t experiment on living people’s brains. One way around this is to create organoids, which are miniature organs grown from stem cells. New research finds that nearly half of American teens say they are almost constantly on their phones, but how much is too much? Experts say to watch out for these signs.

Adolescents and young adults have progressively become smartphone and internet-dependent. Its addiction is affecting them mentally and physically. Due to its overutilization, it is causing a detrimental effect on them. These dilemmas need to be acknowledged. Furthermore, the goal is to reduce overutilization and overreliance, and the task is to reduce the heavy toll on their mental and psychological condition. We need to review the evidence linking smartphone and social media use with psychological morbidities among adolescents and young adults. The aim of this study is to summarize the present situation and the correlation between smartphones and mental health. Cognitive, emotional difficulties, poor cognitive function, impulsivity, shyness, social networking addiction, low self-esteem, and some medical issues like insomnia, anxiety, depression, and a lack of cognitive control have been linked to excessive smartphone use.Background Depression and anxiety are topical concerns worldwide, especially among adolescents. Besides, biological rhythm disorder as a candidate mechanism for mood disorders is highly prevalent, but relevant research among adolescents in China is presently limited. We conducted the present study to investigate the distribution of multi-dimensional self-rating biological rhythm disorder and the association of self-rating biological rhythm disorders with depression and anxiety symptoms among Chinese adolescents in different academic stages. Methods In the cross-sectional study, 3693 students aged 11–23 from Zhengzhou City, Henan Province, China were included. The Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder (GAD-7) were used to evaluate symptoms of depression and anxiety, respectively. Additionally, the Self-Rating of Biological Rhythm Disorder for Adolescents (SBRDA) was used to assess status of biological rhythm disorders. Multivariate logistic regression was developed to explore factors potentially associated with symptoms of depression and anxiety stratified by academic stages. Results Among all participants, 44.14 and 36.15% suffered from depression and anxiety symptoms, respectively. On average, participants scored 74.66 ± 19.37 on the measure of total biological rhythm disorder. Adjusted for demographic confounding factors, the logistic regression analysis showed higher scores of total biological rhythm disorder were associated with more severe depression (OR = 14.38, 95%CI: 11.38–18.16) and anxiety symptoms (OR = 11.63, 95%CI: 9.14–14.81). The similar results were also found in the stratified analysis by academic stages. Conclusions Self-rating biological rhythm disorders are significantly associated with depression and anxiety symptoms among adolescents. Discrepancy across academic stages should also be taken into account in establishing public health strategies.A stable component of body mass index appears linked to a person’s likelihood of experiencing social discrimination, according to a study published in Adaptive Human Behavior and Physiology. Using genetic prediction models, the study found that higher trait-BMI was linked to worse discrimination and declining life satisfaction among older adults. A recent study tested a new experimental procedure that may help researchers investigate treatments for social anxiety disorder. The study authors developed a social stress test that induces symptoms of social anxiety disorder and can be conducted entirely online. The findings were published in the journal Psychiatry Research.

Bed Habits

One insomniac’s descent into the world of sleep research to understand what screens before bed are doing to our brains.A study published in the Journal of Health and Social Behavior has found that boys and men experience more social isolation than girls and women, with this difference disproportionately affecting the unmarried, or individuals with disrupted relationship histories. Further, levels of social isolation increase from adolescence through later life for both genders. The literature has shown that mobile phone addiction is an important risk factor for depression. However, the internal mechanisms of mobile phone addiction leading to depression are still not clear. This study examined the mediating role of sleep quality and moderating role of peer relationships in the association between mobile phone addiction and depression. A sample of 450 Chinese medical students were recruited to complete measures of mobile phone addiction, depression, sleep quality and peer relationships. In this study, SPSS 25.0 and macro PROCESS were used to conduct statistical analysis on the collected data. The results showed that sleep quality partially mediated the association between mobile phone addiction and depression. Moreover, the effect of sleep quality on depression was moderated by peer relationships. The present study can advance our understanding of how and when mobile phone addiction leads to depression. Limitations and implications of this study are discussed.There’s a common refrain of “nice guys finish last” from men who have trouble attracting women, but is being nice the real problem? A study published in Personality and Individual Differences suggests that involuntarily celibate men show higher levels of misogyny and hostility toward women.

Depression, self-harm and suicide are rising among American adolescents. For one 13-year-old, the despair was almost too much to take.A new study suggests that young adults who use more social media may have an increased risk of developing depression within six months, regardless of their personality type or traits.Increased engagement with politics on social media predicts future decreases in racial resentment among liberals in the United States, according to new research published in Computers in Human Behavior.
