Engaging in fast-paced video games late in the evening doesn’t invariably compromise sleep quality. Quite the opposite, researchers have discovered they can actually benefit psychological well-being. In a study featured in the journal Sleep Medicine, experts clarified the specific conditions under which this beneficial effect is observed.
The study involved 18 young adults who had minimal prior experience with video games. Over several weeks, the scientific team contrasted three scenarios: their usual routine, watching TV series before bedtime, and playing a shooter game for one hour in the evening. Participants were equipped with sleep trackers, underwent cognitive assessments, and completed questionnaires regarding their general well-being metrics.
The conclusion reached was that the one-hour evening gaming session did not cause any deterioration in objective sleep parameters. Key aspects such as the time taken to fall asleep, the duration of deep sleep phases, and the frequency of awakenings remained unchanged. In contrast, sleep quality actually saw a slight decline when participants watched television series.
The specialists attribute this phenomenon to the fact that the intense practice of various cognitive and motor skills during gaming stimulates mechanisms responsible for processing information during sleep. This activity helps maintain a stable sleep structure.
Furthermore, following the gaming sessions, participants demonstrated enhanced performance on tests measuring visuospatial working memory. This type of memory is crucial for managing and processing visual inputs and other external data, and it is highly necessary for spatial orientation.
Positive shifts were also noted in the participants’ psychological states. Stress levels decreased after several evenings spent playing video games. However, no significant alterations were detected in measures of anxiety or depression.
Crucially, in this experiment, gaming sessions were limited to one hour and concluded at least 30 minutes before participants went to sleep. Other research has established that longer gaming periods, especially those that encroach upon actual sleep time, tend to have the opposite—detrimental—effect on sleep quality.
There is an additional factor to consider: these outcomes pertain only to individuals with no prior history of gaming. Experienced gamers may exhibit different effects, as their brains have already acclimatized to such types of stimuli.
