Scientists Confirm: This is the Best Activity for the Brain Before Sleep

Scientists have confirmed that reading before sleep is the best activity for the brain prior to rest. In today’s fast-paced and digital world, many people around the globe make evening rituals include endless scrolling through social media on their smartphones. However, numerous scientific studies clearly indicate that simply replacing screen blue light with printed pages can bring significant benefits for human mental health and overall sleep quality. Prominent psychologists and neuroscientists have thoroughly examined the complex mechanisms behind this habit, revealing that it not only effectively reduces high cortisol levels and improves human empathy but also actively prepares an overburdened brain for much deeper and more restful nighttime sleep. According to Real Simple, the findings highlight the unique advantages of this practice. One of the most significant and frequently mentioned proven benefits of reading before bed lies in its exceptional ability to quickly reduce stress after a demanding workday. A recent study conducted by researchers at the University of Sussex revealed that just six minutes of focused reading can drastically lower stress levels, reducing them by as much as 68 percent. Cognitive neuropsychologist David Lewis, who led this thorough research, emphasizes the specific power of written words. He states: “Reading introduces us into an altered state of consciousness and does not merely provide distraction, but cognitively and emotionally rejuvenates us.” This deep and fundamental process of relaxation has very measurable and tangible physiological effects on the human body. According to expert findings, reading slows heart rate and simultaneously significantly reduces accumulated tension in neck and back muscles. Consequently, the existing level of cortisol, widely known in modern medicine as the primary stress hormone, automatically decreases. Extremely high cortisol levels in late evenings can seriously and long-term disrupt sleep, so any cognitive activity that naturally and without medication lowers it is extremely beneficial for optimal preparation of the entire body for necessary nighttime rest. An exhausted brain then surely transitions from a state of high alertness to one of complete calmness. Reading, especially regular reading of quality literary fiction, can significantly and permanently improve human empathy and strongly stimulate the creation of entirely new neural connections. A recent study conducted at Emory University used advanced functional magnetic resonance imaging to precisely track brain activity among participants who carefully read novels. Official results showed a greatly increased connectivity in areas of the brain primarily responsible for basic language understanding, as well as in specific regions closely linked to sensory and motor experiences. This phenomenon, known in science as embodied cognition, blurs the thin boundary between pure imagination and actual physical experience in the mind of the reader. Through deep immersion in complex and intriguing stories and analyzing the lives of different fictional characters, regular readers actively and unconsciously develop an innate ability to better understand others' hidden emotions and different life perspectives. Dr. Sonia Kapur notes: “Reading fiction exceptionally helps calm an overburdened mind because it transports an exhausted reader into an imagined world, providing him with a completely safe and temporary distance from his real worries.” According to Kapur, when readers carefully follow characters with whom they can identify, they actually much better understand their own suppressed emotions, directly stimulating the parasympathetic nervous system. It is crucial to mention that the type of device used for evening reading plays an absolutely decisive role in achieving all the aforementioned desired results. Physical, traditional paper books convincingly represent the best and healthiest possible choice, far superior to modern smartphones or various popular devices.
