Experiencing wild technology can definitely disrupt sleep patterns, especially if the technology is stimulating or anxiety-inducing. The bright lights, constant notifications, and mental stimulation from technology can make it difficult to wind down and relax before bed.

It's important to establish a bedtime routine that includes unplugging from technology at least an hour before bed to help improve sleep quality. **

Today's youth may sleep particularly late due to digital media for several reasons. The use of smartphones, social media, and video games can lead to increased screen time, which can disrupt sleep patterns.

Additionally, the constant connectivity and FOMO (fear of missing out) associated with digital media may lead to young people staying up later to stay engaged with their peers. However, it's important to note that individual factors such as school schedules, extracurricular activities, and personal habits also play a role in determining sleep patterns among youth. **
