Did you know? Poor sleep can lower testosterone levels by 10–15% in just one week, mimicking the effects of aging 10–15 years. Testosterone is vital for muscle strength, sexual health, and overall well-being, and most of it is produced during deep sleep stages.
Start improving your sleep and testosterone today with these simple steps. Let’s dive deeper into how sleep impacts hormone health and what you can do about it.
Your body’s testosterone production runs on a specific schedule while you sleep. Levels start to rise shortly after you fall asleep, reaching their peak during the first REM cycle . Different sleep stages play a role in hormone release - testosterone tends to be higher during pre-NREM periods compared to pre-REM periods .
Not getting enough sleep can have a noticeable impact on your testosterone levels. A study led by Eve Van Cauter, PhD, revealed that sleeping only five hours a night for a week can cause a 10–15% drop in testosterone in healthy young men. That’s similar to the decline seen with aging 10–15 years . Alarmingly, around 15% of working adults in the U.S. sleep less than five hours each night .
Testosterone levels naturally follow a daily rhythm tied to your sleep-wake cycle. Here’s how it typically looks:
| Time Period | Testosterone Level | Notes |
|---|---|---|
| 8:00 AM | Highest | Peaks after waking |
| 11:00 PM – 7:00 AM | Elevated | Stays elevated through the night |
| 7:00 PM – 10:00 PM | Lowest | Drops to its lowest in the evening |
"As research progresses, low sleep duration and poor sleep quality are increasingly recognized as endocrine disruptors." - Eve Van Cauter, PhD, professor in medicine and director of the study
Recognizing this daily cycle can help you make smarter choices to support healthy hormone levels.
Low testosterone can show up in both physical and mental ways. Studies estimate that 4 to 5 million men in the U.S. experience hypogonadism, with about 1 in 4 men aged 40–70 affected by this condition .
| Physical Signs | Mental/Emotional Signs |
|---|---|
| Decreased muscle mass | Depression |
| Increased body fat | Irritability |
| Reduced strength | Anxiety |
| Sexual dysfunction | Poor concentration |
| Loss of body hair | Mood swings |
| Gynecomastia | Low motivation |
| Shrunken testicles | Social withdrawal |
"People with hypogonadism, or low testosterone, will often say they have no energy, no desire for sexual activity and that they noticed a decrease in muscle mass" .
"Sometimes, people are actually misdiagnosed with clinical depression and they might instead have low testosterone or hypogonadism. It is therefore important to rule-out a physical cause of the condition, such as hypogonadism, prior to treatment" .
In fact, research shows that 35% to 50% of men with hypogonadism also experience clinical depression . These symptoms often overlap with poor sleep patterns, which can further disrupt testosterone production.
Poor sleep can have a direct impact on testosterone levels, creating a cycle that’s hard to break. Some common signs of poor sleep include:
Over time, consistently sleeping fewer than 7–9 hours per night can reduce testosterone levels . Sleep disorders like sleep apnea are especially concerning, as they are closely tied to lower nighttime testosterone production . Symptoms such as loud snoring, pauses in breathing, or waking up gasping for air could point to sleep apnea as a contributing factor.
"Low testosterone levels are associated with reduced well being and vigor, which may also occur as a consequence of sleep loss" – Eve Van Cauter, PhD, professor in medicine .
The effects of poor sleep on testosterone can mimic aging by 10–15 years. If you notice several of these symptoms, it’s a good idea to consult a healthcare provider or urologist for a proper assessment . Spotting these signs early can help you take steps to improve both your sleep and testosterone levels.
Getting quality, consistent sleep plays a big role in maintaining healthy testosterone levels. To keep your hormones balanced, focus on building regular sleep habits and creating a peaceful sleep environment.
Aim for a bedroom temperature between 60–67°F, keep the space dark and quiet, and minimize any noise or light disruptions . Since testosterone peaks around 8 a.m. and dips to its lowest by 8 p.m. , sticking to a regular sleep routine is crucial.
Here are some tips to help:
Exercise not only boosts testosterone but also improves sleep quality.
"We have solid evidence that exercise does, in fact, help you fall asleep more quickly and improves sleep quality" - Charlene Gamaldo, M.D., medical director of Johns Hopkins Center for Sleep at Howard County General Hospital .
A study from 2007 found that men who did strength training three times a week for four weeks saw noticeable increases in testosterone levels, both immediately after workouts and over time . To get the most out of your workouts, try these:
Pair good sleep habits and exercise with a balanced diet and supplements to further support testosterone production.
A nutrient-dense diet is essential for both better sleep and hormone health. Focus on:
For extra support, consider supplements like the T3 Multiplier Testosterone Booster from Supernatural Man, which includes boron and other ingredients backed by research. Always consult your healthcare provider before starting any new supplement.
Timing matters too: take magnesium in the evening to aid sleep and vitamin D in the morning with a meal containing healthy fats for better absorption.
Not getting enough sleep can significantly lower testosterone levels, with effects comparable to aging 10–15 years . Keeping your weight in check is also key - research shows that losing just 5% of body weight can increase total testosterone by 2 nmol/L (58 ng/dL) .
"Sleep disorders including a decrease in sleep quality, inadequate sleep duration, disruption of circadian rhythm, and sleep breathing disorders such as sleep apnea can all negatively affect the testosterone production cycle and result in decreased testosterone production, and consequently decreased blood testosterone levels." - John Lynam, D.O.
