Recent studies indicate that video games may influence cortisol levels, but the effects vary depending on game type, session length, and timing. Cortisol, a hormone associated with stress response, does not uniformly respond to gaming. Research from 2026 highlights the conditions under which gaming might serve as a short-term tool for stress relief, although it is not a substitute for medical treatment.

The strongest evidence comes from controlled lab studies that measured changes in salivary cortisol and physiological markers before and after gaming sessions. Short gaming sessions following acute stressors seem to support recovery, while longer sessions may disrupt hormonal rhythms. For example, a 2025 study by Wagener et al. involved participants who experienced a cold-pressor stress task. After playing segments of "A Plague Tale: Requiem," participants showed decreased cortisol and heart rate regardless of game content, although they reported feeling more stressed during the violent segment.
A 2024 study in *Physiology & Behavior* found that participants assigned to play a violent game exhibited a significant reduction in cortisol while maintaining steady levels of aggression. Similarly, a systematic review published in 2021 in *JMIR Mental Health* concluded that casual games, action-adventure titles, and exergames could alleviate stress after a single session.
In another study from 2021, undergraduate participants who played the calming game "Flower" for 20 minutes demonstrated marked reductions in perceived stress and physiological measures like heart rate and blood pressure—showing results comparable to a mindfulness practice.
However, a 2025 randomized controlled trial found that late-night gaming could disrupt melatonin timing and sleep-wake cycles, potentially complicating hormonal regulation. This highlights the context-dependency of gaming benefits; while short sessions may lead to cortisol reduction, excessive or poorly timed gaming could exacerbate stress responses.
The research underscores that while video games can lower cortisol levels acutely after stress, they are not a reliable long-term strategy for hormone management. Findings show no consistent long-term reductions in baseline cortisol levels tied to regular gaming. The variations in individual responses, especially regarding personality traits, further complicate this landscape.
Games that typically reduce stress include casual titles like "Bejeweled," exergames such as "Wii Fit," and low-stakes multiplayer options. Conversely, high-stress competitive and horror-based games may elevate feelings of anxiety, even if cortisol levels do not rise in tandem.
Overall, experts suggest selecting lower-stakes games and keeping sessions short for effective stress relief. Research indicates that moderation and mindful choice of game type are key in utilizing gaming as a coping mechanism, emphasizing that while gaming can aid recovery from acute stress, it should be viewed as one tool among many in managing stress effectively.
