"Both Maria and Christine use meditation and relaxation techniques to calm down in the evening and start the day well. But even though they have been doing it for many years, they find it difficult to implement without digital aids.
"The paradox is that when we try to find peace through music or meditation or do other good things for our sleep, we very often have to use an app on our mobile. It's easy to get distracted by notifications or tempted to check a feed," says Christine.
The mobile phone thus works against its purpose:
"The design and content on the mobile are cognitively and emotionally stimulating, pushing the brain towards activation and stress. It's not particularly useful when trying to calm down," says psychology student Maria.
Blue light can disrupt sleep
Many have heard that the blue light from the mobile screen is not good in the evening, but may not know that it has a physiological explanation.
"Melatonin is a hormone that promotes sleepiness. The production of this hormone increases when it gets dark in the evening and is at its highest in the middle of the night for most people. The blue light from the mobile screen inhibits the production of melatonin. This can lead to taking longer to fall asleep and taking longer to get into the deeper stages of sleep," explains Maria.
"Teenagers already have a natural shift in the peak production of melatonin, so when they are also exposed to screen light in the evening, many teenagers may not have enough of the important quality sleep before they have to get up for school," adds Christine."
