Just two hours of daily screen time lowers psychological well-being and increases negative behaviors in preschool children. www.google.de
Technology enriches our lives, enhancing communication, improving healthcare, and providing access to vast amounts of information. However, the amount of time we spend on the devices that deliver that technology may be harmful, especially for young children. A recent study found that two hours or more of daily screen time among preschoolers lowers psychological well-being.
Researchers analyzed data from the 2018-2021 National Survey of Children’s Health, focusing on children aged six months to five years. Primary caregivers reported the children’s daily screen time and provided information about their flourishing and externalizing behaviors – indicators of psychological health.
They found that over the four-year study period, 50.9 percent of the children had high screen time, defined as one or more hour daily for children aged six months to one year and two or more hours daily for children aged two to five years. The percentage of children with high screen time increased to 55.3 percent during the pandemic in 2020 and was even higher among children living in poverty (60.9 percent). More than two hours of daily screen time was linked to less flourishing and more externalizing behaviors for children aged three to five years.
Flourishing refers to the presence of positive emotions, relationships, and adaptive functioning. It plays a crucial role in reducing the risk of antisocial behaviors later in life. Externalizing behaviors, such as hyperactivity and aggression, reflect maladjustment to the external environment. They can hinder learning and relationships and may lead to juvenile delinquency and adult violence.
These findings suggest that excessive screen time may harm psychological well-being in preschool-aged children. Parents and caregivers should be mindful of screen time limits to promote better mental health outcomes for young children.

Wearable device may predict inflammatory bowel disease flare-ups. www.sciencedaily.com
Inflammatory bowel diseases, a group of conditions characterized by chronic inflammation of the digestive tract, affect the lives of nearly seven million people worldwide. The two most common inflammatory bowel diseases are ulcerative colitis and Crohn’s disease. A report published in 2020 describes a wearable device that detects the presence of biomarkers associated with inflammatory bowel diseases in sweat, potentially signaling a symptom flare.
A common feature of many inflammatory bowel diseases are periods of remission and relapse, often referred to as “flares.” During flares, interleukin-1 beta (IL-1 beta) and C-reactive protein (CRP), are often elevated. IL-1 beta is a proinflammatory cytokine that mediates the body’s inflammatory response. CRP is a protein that increases in the blood with inflammation and infection.
The authors of the study developed a wearable, watch-like device that monitored levels of IL-1 beta and CRP in the sweat of 20 healthy adults (18 to 65 years old) over a period of up to 30 hours. They studied healthy people to help establish the levels of these two biomarkers in people without inflammatory bowel disease. A removable strip on the device collected the sweat, providing real-time monitoring of the biomarkers. They also measured the biomarkers using a standard assay and compared the two assessments.
They found that the device was highly accurate at measuring sweat levels of IL-1 beta and CRP, compared to measurements with the standard assay. Their findings demonstrate proof-of-feasibility for a wearable device that can signal an inflammatory bowel disease flare. Use of such a device may offer a non-invasive way to help people with inflammatory bowel disease track their inflammatory status and help guide clinicians' treatment decisions.
The authors of this study later measured pro-inflammatory proteins in the sweat of people with COVID-19 to predict cytokine storm, a potentially life-threatening condition that occurs when an infection provokes an excessive immune response. They found that their sweat-based sensor detected cytokine levels in passive sweat that correlated with cytokine levels in the patients' blood.

The American Academy of Pediatrics recommends avoiding screen time exposure for children under the age of 18 months and limiting screen time to one hour per day for children between the ages and two and five years. As digital devices become more ubiquitous, however, screen time use among children is increasing. Findings from a new study indicate that screen time exposure begins in infancy and increases as a child ages.
The study was part of the Upstate New York Infant Development Screening Program, a population-based, prospective cohort study of nearly 3,900 children between the ages of one and three years. The data were drawn from reports of children’s screen time, which included television, movie, and computer game use at 12, 18, 24, 30, and 36 months of age.
The authors of the study found that average screen time exposure among one-year-old infants was nearly one hour per day (53 minutes). Screen time exposure increased over time as children got older to an average of 2.5 hours per day (150 minutes) by the age of three years. Children who were in home-based childcare or were born to first-time mothers were more likely to have the highest screen time exposures by the age of eight years.
Previous research has demonstrated that children who have more screen time exposure have poor structural integrity in areas of their brains that support language and literacy skills. Other research indicates that high screen time is associated with poor academic performance, decreased physical activity, and negative social interactions in middle childhood.
