Causes of ED
Lack of sleep and erectile dysfunction: how sleep affects your erections
If you sleep five or six hours a night and wonder why your drive has dropped, the two may be linked. Research shows a clear connection between lack of sleep and erectile dysfunction, mainly through testosterone, stress and blood vessel health.
In short: Yes, poor sleep can contribute to erectile dysfunction and low libido. Most testosterone is released during sleep, and studies show that a week of restricted sleep can lower testosterone in young men. Sleep apnoea, shift work and insomnia are all linked with ED. Most men need seven to nine hours of good-quality sleep.
How sleep affects erections
Testosterone
Testosterone rises during sleep, peaking in the early morning. A well-known study found that restricting young men to five hours of sleep a night for a week lowered their daytime testosterone noticeably. Lower testosterone can reduce desire and weaken erections.
Night-time erections
Healthy men have several erections during deep (REM) sleep. These help keep penile tissue oxygenated. Broken sleep reduces them, which may matter for long-term erectile health.
Stress hormones
Sleep loss raises cortisol and activates the stress response, which works against arousal.
Blood vessels and weight
Chronic poor sleep is linked with high blood pressure, insulin resistance and weight gain, all major causes of ED.
Sleep apnoea and ED
Obstructive sleep apnoea, where breathing repeatedly stops during sleep, is common in men with ED. Signs include loud snoring, gasping at night, morning headaches and daytime sleepiness. Treating sleep apnoea has been shown to improve erectile function in some men. If you suspect it, see an appropriately registered medical professional for assessment.
Shift work
Men who work night shifts are more likely to report sexual problems, probably because their body clock is disrupted.
Natural ways to sleep better
- Keep a regular bedtime and wake time, even at weekends.
- Aim for seven to nine hours in bed.
- Keep your room cool, dark and quiet, and charge your phone outside the bedroom.
- Avoid caffeine after early afternoon. See does coffee help erectile dysfunction.
- Limit alcohol, which disrupts deep sleep.
- Get daylight and exercise during the day.
- Wind down with reading, a warm shower or slow breathing.
Natural support from a naturopath
Herbal remedies such as rooibos, chamomile or, for some men, ashwagandha may support relaxation. See ashwagandha benefits for men. A naturopath can build a plan for sleep, stress and sexual health together. You might also find signs of low testosterone in men over 40 helpful.
