Understanding the Connection Between Lack of Sleep and Erectile Dysfunction

A good night’s sleep does far more than rest your body; it actively supports most of your bodily functions, from cardiovascular health to sexual wellness. 

Conversely, not getting enough sleep can contribute to erectile dysfunction (ED), an issue that affects about 322 million men around the globe. 

To explain this connection, leading men’s health specialist and board-certified urologist Robert J. Cornell explores how poor sleep quality can impact your sexual health, and how to get both back on track.

What happens when you sleep

There are four stages of sleep, including:

• Stage 1 — Light sleep.
• Stage 2 — Deeper light sleep, when your muscles relax and your heart and breathing rates go down.
• Stage 3 — Deep sleep, during which your blood pressure, breathing, and heart rates reach their lowest points. This stage is when your body repairs tissues, builds bone and muscle, and strengthens your immune system.
• Stage 4 — Rapid eye movement (REM) sleep, which supports cognitive function.

Most adults need about 7-9 hours of sleep so they can fully cycle through these stages and reap the benefits. Unfortunately, 1 out of 3 Americans don’t get enough uninterrupted sleep each night.

Many factors can drive this universal lack of sleep; conditions like insomnia and sleep apnea account are common ones.

How sleep influences sexual function

Your body undergoes a metabolic reset each night that regulates your hormones, including testosterone. If any hormone levels aren’t where they should be, it works to restore balance. However, if your sleep is interrupted and you don’t reach deep sleep, this can negatively impact the production of hormones like testosterone, which can affect sexual function.

Also, typically in the deeper stages of sleep, your cardiovascular system gets a much-needed break as your heart rate slows and blood pressure goes down. Without this rest, your cardiovascular system works overtime and is under a lot of stress, which can lead to premature blockages in your blood vessels that disrupt blood flow to your penis.

Finally, poor sleep can affect sexual health by reducing sleep-related erections. Most men experience erections throughout the night, which helps to deliver oxygen to penile tissues and prevent fibrosis (scar buildup). Without good sleep, you might not have sleep-related erections, and studies show that can lead to erectile impairment.

Improving your sleep and your sexual health

Aiming for better sleep is a great goal; it not only helps with your sexual function, but your overall health. The first step is to figure out what’s behind your lack of sleep so you know what changes to make.

Dr. Cornell can help identify the source of your ED and assess whether sleep issues are contributing to it. He may also recommend tools such as medications, vacuum devices, and penile implants that can help restore sexual function while you concentrate on getting better sleep.
