How Stress, Sleep, and Cortisol Affect Men’s Performance

High stress levels, inadequate sleep, and chronically elevated cortisol are commonly associated with reduced energy, lower daytime focus, and changes in hormonal balance in men. Prolonged stress can lead to sustained cortisol release, which is related to alterations in testosterone production, metabolic efficiency, and cognitive performance, often contributing to feelings of fatigue and mental strain.

Adequate, high-quality sleep plays a vital supportive role in overall hormonal regulation. Research shows that healthy sleep correlates with normal nighttime testosterone secretion, balanced cortisol rhythms, and cognitive function recovery, which promotes alertness, memory, and emotional stability.

Observational studies published between 2022 and 2025 report correlations between chronically elevated cortisol levels and lower free testosterone measurements, along with reduced activity in brain regions involved in executive function and memory, such as the prefrontal cortex and hippocampus. These associations have been linked to slower reaction times, reduced working memory performance, and increased emotional reactivity. However, these findings reflect population-level trends and do not establish causation.

In this article, we provide an educational overview of relevant physiological mechanisms, summarize findings from recent peer-reviewed analyses, and discuss lifestyle-based strategies that may help support energy, focus, and overall vitality.

How Stress and Cortisol May Affect Men’s Energy Levels

Cortisol and Energy Regulation in Men

Under conditions of constant or chronic stress, the hypothalamic-pituitary-adrenal (HPA) axis may remain more active than usual. Elevated cortisol levels are associated with changes in how the body metabolizes hormone precursors such as pregnenolone, which plays a role in the synthesis of numerous hormones, including cortisol and testosterone.

Some studies suggest that prolonged stress may be associated with changes in hormones involved in testosterone regulation, including luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These changes have been associated with lower average testosterone measurements at the population level, although individual responses vary, and these findings do not establish direct causation.

A 2023 meta-analysis of 23 observational studies involving approximately 4,800 men reported an inverse association between perceived stress levels and total testosterone concentrations. The authors noted a statistically significant correlation between higher reported stress and lower testosterone values; however, these results describe group-level trends and are not predictive for any individual.

Cortisol and Daily Energy Levels

Chronic elevation of cortisol levels is associated with changes in the body’s regulation of glucose metabolism and insulin sensitivity. During prolonged stress, the body may shift toward increased glucose production and altered energy utilization to support short-term demands.

Some researchers suggest that ongoing stress may influence mitochondrial efficiency, which plays a role in cellular energy production. In everyday terms, these physiological patterns are commonly associated with feelings of daytime fatigue, reduced physical stamina, and changes in body composition, including increased central fat accumulation. Visceral fat is associated with inflammatory signals, which, over time, can additionally affect the balance of stress hormones.

Practical Methods

• Research indicates that short-term cold exposure may be associated with healthy stress hormone responses.
• Box-breathing technique (4-4-4-4) practiced for several minutes daily — may help support relaxation and healthy cortisol regulation over time.
• Ashwagandha extract (600 mg/day) — some studies suggest it may support the body’s stress response and overall hormonal balance.
• Strength training (3–4 times per week) — regular resistance exercise is associated with improved stress resilience and healthy cortisol regulation.

Influence of Healthy Sleep on Androgens

Max Testosterone During Deep Sleep

A significant portion of daily testosterone production occurs during slow-wave sleep, according to some studies. (PubMed PMID: 32081788)

How Broken Sleep Raises Cortisol

Awakenings after falling asleep (even unnoticed) activate the HPA axis and raise nighttime cortisol. Research indicates that repeated or extended awakenings during sleep may be linked to elevated morning cortisol.

Healthy Sleep Tips for Men

Some studies suggest that keeping the bedroom cooler (around 60–64°F) may support deeper stages of sleep

• Some research suggests that reducing the amount of time spent on screens before bed may support natural melatonin production and healthy sleep onset.
• Research indicates that taking magnesium threonate or glycinate before bed may be associated with supporting healthy sleep..
• Consuming slow-digesting carbs (50–80 g) a few hours before bed may be associated with supporting relaxation and sleep quality in some research.
• Exposure to red light in the evening may be linked to supporting natural circadian rhythms and sleep preparation.

Daily Habits for Staying Energized

Vitamins and Minerals to Support a Healthy Lifestyle

Several nutrients have been studied for their potential role in supporting the body’s stress response and overall hormonal balance. The findings below reflect research observations and do not imply guaranteed outcomes.

• Zinc (30–50 mg/day) — some research suggests that maintaining adequate zinc levels may be associated with supporting healthy cortisol regulation and overall hormonal balance. (Journal of Biomedicine and Translational Research, 8(1):26-31, DOI: 10.14710/jbtr.v8i1.13808).

• Magnesium (400–600 mg) — some studies suggest that magnesium intake may help support healthy cortisol levels over time. (PubMed PMID: 39252819, 2024).
• Vitamin D (4,000–6,000 IU if deficient) — some studies suggest that optimizing vitamin D levels may help support healthy cortisol levels over time. (PubMed PMID: 39452471, 2024).

Recent peer-reviewed research suggests that lifestyle factors—including consistent, high-quality sleep, balanced nutrition, regular physical activity, and effective stress management—are associated with healthier cortisol patterns and hormonal balance in men. (Nutrients 2025, 17(23), 3772; https://doi.org/10.3390/nu17233772).

Conclusion: Reclaim Your Energy and Daily Focus

Stress levels, sleep quality, and overall lifestyle habits affect your daily energy, concentration, and motivation. Prolonged stress and poor sleep are commonly associated with fatigue, lower alertness, and reduced daily performance. Supportive practices—such as consistent sleep, balanced nutrition, regular physical activity, and mindfulness—are widely recognized for helping maintain overall well-being.

Research suggests that men who aim for 7–9 hours of sleep, manage stress, and follow a balanced diet tend to report higher energy, better mental clarity, and sustained vitality in demanding lifestyles. Making small, gradual changes, such as morning breathing exercises, adjusting your sleep schedule, or ensuring adequate intake of essential nutrients like magnesium, can be a practical first step. Over time, a combination of balanced nutrition, regular exercise, and consistent sleep can help increase energy and concentration throughout the day.

Keep track of how you feel as you introduce these habits. Small, consistent steps toward a balanced lifestyle can help you feel more alert, confident, and clear-headed throughout the day.
