Saskia Johanna Rosenow advises: Handy-Detox: Feel more comfortable without 150 checks a day

Saskia Johanna Rosenow is not only nutrition expert, but also a advocate of a healthy handling of digital media. In your current Instagram post If she takes up a topic that affects us all: excessive mobile phone use.

We look at our cell phone every four to six minutes – that’s more than 150 times a day. What is often considered a simple distraction is actually a conditioned dopamine loop. Every push notification, every update and endless scrolling means that the brain is constantly looking for something new, even if there is actually nothing new.

The consequences of long use of cell phones are serious. New studies show that more than five hours of cell phone use per day affect concentration and memory, intensify anxiety and even deteriorate the quality of sleep. The risk of depression increases by 25 percent, as studies by BMC Medicine (2025) and PNAS NEXUS (2023) show.

Change habits

But simply lying the cell phone away does not solve the problem. According to a study by the London School of Economics, many people simply turn to other screens if the cell phone is out of reach. The real problem is the habit of constantly looking for new notifications or updates.

Rosenow gives valuable tips: Use your cell phone less than two hours a day for only seven days. Interrupt the loop with targeted habits instead of simply restricting yourself. Screen time can be easily replaced by walks, silence, real contacts and sleep.

The scientific results that Rosenow cited speak for themselves: less screen time means less fear (- 18 percent), more well-being (+ 16 percent), better concentration, relaxing sleep and intellectual clarity. Even cognitive decay can be turned back by ten years.

Rosenow advises her followers: “Try the two-hour rule this week. Set limits. Pay attention to what happens if you don’t get them.”
