It has been known for a long time that sleep is critical in order to function well sexually. Or put differently, we have known for many years that lack of sleep can cause erectile dysfunction.
The sleep cycle consists of 4 stages, where each stage is a deeper and deeper kind of sleep. The last stage is also called REM sleep (rapid eye movement sleep) because during this stage our eyes move rapidly from side to side.
We normally go through 4-5 sleep cycles per night.
But which of these sleep stages are most important for sexual health?
A new research study on 12 healthy males may have given us the answer.
In this study, the researchers interrupted sleep stage three, the deepest form of non-REM sleep and the sleep cycle that is also called slow-wave sleep.
This sleep cycle was interrupted so that the men spent 54.2% less time in this sleep stage and more time in stage one and two. However, total sleep time was not materially reduced.
The following day, the researchers measured the levels of testosterone and its precursor 17α-hydroxyprogesterone.
What was the result?
Reduced levels of testosterone and 17α-hydroxyprogesterone.
The researchers concluded therefore that the reduction of these hormones was associated with the time spent in sleep stage three.
And testosterone is the primary male sex hormone that governs and regulates your sexual functions. With low levels of testosterone, you are much more likely to suffer from erectile dysfunction and a low libido.
With this research study we now know that not only is the amount of sleep you get incredibly important, but also the quality of your sleep.
Meaning, you need to spend an adequate amount of time in deep sleep stages.
However, one thing to note: The participants who spent less time in sleep stage three, also spent less time in sleep stage 4. Therefore, it is possible that both these deep sleep stages are very important for testosterone production.
