Can Napping Boost Testosterone Levels?
Many of us know that mid-afternoon slump. That feeling when your energy dips, your focus fades, and you feel your body crave that afternoon nap. And after a few short winks we wake up feeling rested and refreshed. But could that nap do more than just refresh your mind? Could that quick kip actually help your testosterone levels too?
Testosterone, which plays a key role in men’s health and sexual performance, would benefit from a small boost now and again, and is that nap the very boost it needs?
The Connection Between Sleep and Testosterone
Testosterone is the primary male sex hormone responsible for many aspects of men’s health such as muscle mass, mood, and sexual function.

Research has shown that most men’s testosterone production occurs during deep sleep, particularly in the early morning. When sleep is cut short, or disrupted, these testosterone levels can drop significantly. One study even found that those with restricted sleep (5hrs per night) showed a 10-15% decreased level of testosterone compared to their fully rested levels.
Chronic sleep deprivation, where a person regularly does not get enough sleep over a significant period, doesn’t just make you tired, but can also affect your mood, libido, and can even contribute to erectile dysfunction (ED).
Does a Nap Make Up for Lost Sleep?
In short, no. A nap won’t completely replace a full night’s rest. But, it can help reduce fatigue and support hormone balance. Short naps (20-40 minutes) have been shown to be enough to reduce stress hormones such as cortisol, which can indirectly help to maintain healthier testosterone levels.
Longer naps, however, (those longer than an hour) may go on to disrupt nighttime sleep, which can have the opposite effect. So, while a short nap in the mid-afternoon might help to refresh those hormone levels and help you feel more focussed later in the day; too long will just mess with your sleep cycle.
