Chronic stress doesn’t just affect your mood. Experts say it can disrupt testosterone, recovery, sleep, libido and physical performance – often so gradually that most men never spot the warning signs
Most men understand that stress can leave them feeling tired, distracted, and irritable; what so many don’t realise is just how deeply it can affect the body behind the scenes, influencing everything from hormone levels and recovery to libido and physical performance.
According to Dr. Kenneth Ro, MD, an internal medicine and emergency physician with more than 35 years of experience, chronic stress may be one of the most overlooked factors affecting men’s health today.
“Chronic stress affects virtually every major hormonal system in the body,” says Dr. Ro. “When stress becomes prolonged, the body shifts resources toward survival rather than optimisation. Over time this can affect sleep, metabolism, recovery, appetite regulation, mood, and reproductive hormones.”
The problem, he explains, is that while the human body is built to handle periods of stress, modern life often keeps people stuck in this state. “The body is remarkably adaptive in the short term,” he says. “The challenge is that many people remain in a state of chronic stress for years rather than days or weeks.”
Can stress affect testosterone?
Testosterone is often discussed as a singular issue, but Dr. Ro says reality is that it’s far more connected to our lifestyle than we might think. “Testosterone does not exist in isolation,” he explains. “Sleep quality, recovery, body composition, exercise habits, metabolic health, and chronic stress all influence testosterone production and function.”
When we experience chronic stress, our testosterone levels decline, but Ro says that’s not the only problem. “Equally important is the fact that men often begin experiencing symptoms associated with lower testosterone, including reduced energy, decreased libido, diminished recovery, and lower motivation.”
One of the biggest concerns is the effect stress can have on good quality sleep. “Testosterone production is closely tied to restorative sleep and overall physiological recovery,” says Dr. Ro. “When sleep quality declines and stress remains elevated, testosterone often follows.”
“In many cases, improving recovery habits can have a meaningful impact on hormonal health,” he says.
What are the warning signs to look out for?
Dr Ro says that one of the reasons chronic stress can be so quietly damaging is that the symptoms tend to appear so gradually – meaning we often assume that what we’re experiencing is simply part of the aging process.
“Many men never connect the dots because the changes occur gradually,” says Dr Ro. “They notice less energy, more body fat, poorer workouts, less motivation, and reduced sexual interest, but often assume it is simply aging.”

“In reality, chronic stress can influence all of those symptoms and frequently contributes more than people realise.”
This, however, can make it hard to identify a clear cause. “Some people assume every symptom is due to low testosterone. Others assume everything is caused by aging. The reality is usually more complex,” he says.
“Hormones, sleep, recovery, stress, nutrition, exercise, and relationships are deeply interconnected. Looking at only one piece of the puzzle often misses the bigger picture.”
Why can performance suffer?
Sometimes our performance can be a good indicator of when things are off, says Ro. “Performance is ultimately the visible outcome of what is happening internally.”
“Chronic stress impairs focus, decision-making, creativity, motivation, recovery, and physical capacity,” says Ro. “People may continue performing for a while, but eventually the gap between effort and results begins to widen.”
And while it can be easy to berate ourselves when we’re not performing as well, perhaps the opposite should be the case. Instead it should give us cause to take better care of ourselves.
So, what’s the hidden link?
According to Dr. Ro, the hidden link between stress, hormones and performance comes down to one critical factor. “Recovery,” he says. “Stress influences hormones, hormones influence energy and performance, and recovery is the bridge that connects them all.”
It’s an area that often gets overlooked in a culture obsessed with achieving. “Most people spend tremendous time thinking about productivity and performance while giving very little attention to recovery. In my experience, recovery is often the missing conversation.”
How to break the cycle
“Poor sleep, fatigue, brain fog, increased irritability, weight gain, lower libido, and declining exercise performance often occur together,” says Ro. But with the symptoms of stress overlapping with so many other health issues, it can be so difficult to know what’s affecting what.
“When those symptoms develop alongside a period of prolonged stress, stress should absolutely be considered part of the conversation,” says Ro. “Stress is not simply something happening in their mind. It has real biological effects.”
While stress can be responsible for far more than we realise – it can be hard to know how to stop it. There’s no magic solution for de-stressing -it’s a gradual process. “The solution is usually not found in a single supplement, medication, or quick fix,” says Ro.
“The good news is that small improvements in sleep, exercise, recovery, boundaries, and relationships often create meaningful change when practiced consistently,” he says. “The goal is not perfection. The goal is gradually changing the trajectory.”
His advice for getting started is simple: “Protect sleep. Move your body regularly. Spend more time outdoors. Reduce alcohol. Strengthen important relationships. Create boundaries around work when possible.”
And perhaps most importantly: “Don’t wait for a crisis before making changes. The earlier you intervene, the easier it is to change direction.”
