Spending hours playing Call of Duty: Modern Warfare 4 does not directly mean testosterone levels will decline. However, repeatedly sacrificing sleep to continue gaming may interfere with hormonal health over time.

According to Anneliese Cadena, a clinical consultant at men's health platform Feel30, insufficient sleep and irregular sleeping patterns deserve more attention than gaming itself.

Long gaming sessions can also reduce opportunities for exercise and everyday movement, potentially contributing to weight gain and poorer metabolic health. Frequently replacing balanced meals with sugary drinks, chips and processed snacks may further affect overall well-being.

Building healthier routines can make a difference. Setting a clear gaming cut-off time, taking regular movement breaks and maintaining a consistent sleep schedule can help prevent occasional late nights from becoming an unhealthy habit.

Taking time to unwind after intense competitive matches may also make it easier to relax before bedtime.

Maintaining a healthy lifestyle does not require giving up gaming. Instead, balancing screen time with sleep, physical activity and nutritious meals can help players enjoy their favourite games without neglecting their health.

Standing up between matches, stretching regularly and drinking enough water can reduce some of the downsides associated with extended sitting. Preparing balanced meals before a gaming session can also help limit reliance on convenient but less nutritious snacks.

Protecting sleep is particularly important. Establishing a consistent bedtime and avoiding repeated all-night sessions can support energy levels, concentration and general well-being.

Cadena also highlights the importance of recognising persistent symptoms such as fatigue, reduced libido, low motivation or difficulty building muscle. Although these symptoms can sometimes be associated with low testosterone, they may have several other causes and should be assessed by a healthcare professional rather than self-diagnosed.

Ultimately, enjoying Call of Duty and maintaining good health can go hand in hand. Making room for regular exercise, quality sleep and balanced nutrition allows gaming to remain an enjoyable part of life rather than a habit that takes priority over essential health needs.
