Screens have become part of daily life for most children, but health officials now warn that constant exposure may come with lasting effects.

The Department of Health and Human Services (HHS) released a new advisory on Wednesday highlighting the growing risks linked to excessive screen use among children and teenagers, especially when it comes to sleep quality and mental health.

The report, titled “Surgeon General’s Warning on the Harms of Screen Use,” describes harmful screen habits as a rising public health issue. According to the advisory, children now grow up surrounded by televisions, smartphones, tablets, and computers from an early age. Health officials noted that exposure to screens often starts before a child’s first birthday and steadily increases over time.

“By adolescence, children may spend more time on screens than sleeping or attending school,” the report states. The warning reflects increasing concern over how digital habits may shape behavior, mood, learning ability, and emotional health during key developmental years.

Sleep Disruption Linked to Screen Exposure

One major concern highlighted in the report is the effect of screens on healthy sleep patterns. HHS explained that sleep plays a major role in learning, physical health, emotional stability, and child development.

“A concern at all stages of life, and a particularly important one around children’s screen exposure, is its potential to disrupt healthy sleep,” the advisory noted.

Researchers also pointed to blue light exposure at night as a possible factor behind sleep disruption. The report added that low-frequency wavelengths may also affect sleep, although additional research is still needed.

Schools Begin Limiting Technology Use

The discussion around children’s screen habits has also reached classrooms. Last month, the Los Angeles Unified School District (LAUSD) approved a resolution aimed at reducing screen time in schools. The board passed the measure in a 6-0 vote.

The district plans to set screen time limits for each grade level, remove technology use for students in first grade and younger, and restrict student-led use of YouTube and other streaming platforms. LAUSD described the move as a research-based effort focused on healthier classroom learning environments.

As smartphones and social media continue to shape childhood experiences, concerns around digital safety and emotional well-being keep growing. Health officials believe the latest advisory may encourage parents, schools, and policymakers to take a closer look at how children interact with screens every day.
