Do video games provide health benefits for adults over 35 years of age?

Video Games Offer Meaningful Health Benefits for Adults Over 35

Yes, video games—particularly exergames (active video games requiring physical movement)—provide substantial health benefits for adults over 35, with the strongest evidence supporting improvements in physical activity, cognitive function, and quality of life. The most recent comprehensive guideline framework (2025) establishes that purposefully designed "serious exergames" can serve as powerful tools for health promotion and disease prevention in this age group 1.

Physical Health Benefits

The evidence demonstrates that exergames consistently achieve light-to-moderate intensity physical activity (3-6 metabolic equivalents) during gameplay 2. For adults over 35, particularly older adults, the benefits are most pronounced:

• Muscle strength improvements with effect sizes of 0.64-0.68
• Cardiorespiratory fitness gains with effect sizes of 0.79
• Balance and gait improvements documented across multiple studies 3

These effects are clinically meaningful. A 2024 randomized controlled trial found that exergame-based training resulted in 36.0% of participants reporting falls during 12-month follow-up versus 48.2% in control groups—a significant reduction in fall risk 1.

Cognitive and Emotional Benefits

Video game interventions produce measurable cognitive improvements in adults:

• Processing speed and reaction times: Effect sizes ranging from 0.141 to 3.43
• Memory function: Effect sizes from 0.06 to 1.82
• Task-switching and multitasking: Effect sizes from 0.54 to 1.91
• Mental spatial rotation: Effect sizes from 0.3 to 3.2 4

For cognitive training specifically, small but significant effects were found on working memory (updating memory), though effects on other cognitive domains were more variable 5. Importantly, exergames increase positive emotional experiences and reduce negative affect (effect size d = 0.26) even in populations not highly technologically literate 6.

Quality of Life and Social Engagement

The 2023 systematic review and meta-analysis examining digital health interventions for physical activity in people with chronic conditions found improvements in health-related quality of life, though with high heterogeneity across studies 7. Video game interventions produced positive effects on:

• Social health (effect size d = 0.40)
• Enjoyment and satisfaction (standardized mean difference 0.34,95% CI 0.05-0.64) 8
• Increased social interactions with family, friends, and caregivers 3

Key Mechanisms of Benefit

The 2025 guideline framework explains that exergames work through multiple pathways 1:

1. Neurobiological activation: Stimulation of mesolimbic dopaminergic pathways and brain reward systems
2. Motivation enhancement: Creating positive affective responses that promote sustained behavior change
3. Barrier reduction: Providing accessible, home-based options that overcome traditional exercise barriers
4. Individualized progression: Real-time adjustment of difficulty based on performance metrics

Critical Implementation Factors

The type of game matters significantly. The evidence shows that:

• Exergames (requiring physical movement) are superior to sedentary video games for health outcomes 6
• Purposefully designed "serious exergames" with specific health goals outperform purely entertainment-focused games 1
• Action games and puzzle games are most commonly studied for cognitive benefits 4

Adherence is achievable but requires proper design. High adherence rates (>70% of intended goals) were observed in 53% of studies examining unsupervised home-based exergaming in adults 1. Tailored interventions showed significantly higher adherence (83±15%) versus non-tailored (75±21%) 1.

Important Caveats and Limitations

Safety profile is favorable but not risk-free. There is an increased risk of non-serious adverse events (musculoskeletal soreness, pain) compared to no intervention, but no increased risk of serious adverse events 7. This is expected with any physical activity initiation.

Long-term sustainability remains uncertain. Only 20.6% of participants in one 12-month study reached the training goal of 120 minutes per week averaged across the intervention period 1. Effects tend to diminish over time, though some benefits persist at follow-up for objectively measured physical activity and physical function 7.

Age effects are minimal but present. Meta-regression showed that increasing age was associated with slightly lower effect sizes for physical activity outcomes, though the effect was negligible 7. Importantly, adults aged 75 and over can still benefit, though evidence is more limited in this very old population 9.

Practical Recommendations

For adults over 35 seeking health benefits from video games:

1. Prioritize exergames over sedentary games for physical and cognitive health
2. Choose games with structured progression and individualized difficulty adjustment
3. Target 120 minutes per week as a reasonable goal, though even lower amounts show benefits
4. Combine with social elements (multiplayer, family involvement) to enhance adherence
5. Expect initial musculoskeletal soreness as normal adaptation to increased activity
6. Use commercially available systems (Nintendo Wii, Xbox Kinect, VR platforms) which have demonstrated efficacy 2

The evidence strongly supports that video games, when properly selected and implemented, represent a legitimate and accessible tool for health promotion in adults over 35, with particular promise for those at risk for physical, motor, and cognitive decline 1.
