Yes, screens really can affect sleep. In recent years, the use of screens in daily life has increased significantly. These screens, such as computers, tablets, and smartphones, emit blue light, which can disrupt the body’s natural sleep/wake cycle. This blue light can trick the body into thinking it’s still daytime, making it harder to fall asleep and stay asleep.
Studies have shown that the use of screens before bed can lead to poorer sleep quality and a decrease in the amount of time spent in deep sleep. This can result in fatigue, irritability, and difficulty concentrating the next day. In addition, the blue light emitted by screens can interfere with the body’s production of melatonin, a hormone that helps regulate the body’s sleep/wake cycle.
To help get better sleep, it is important to limit screen use in the hours leading up to bedtime. It is recommended to turn off all screens at least one hour before bed. If this isn’t possible, there are several apps and settings available that can reduce the amount of blue light emitted by screens. Additionally, using night mode settings and dimming the screen brightness can help reduce the amount of blue light emitted.
Overall, screens can have a significant effect on sleep. By limiting screen time and using the available settings to reduce blue light, you can help ensure that you get the best possible sleep.
