Direct answer
Poor sleep raises cortisol, lowers testosterone, and blunts nitric-oxide signaling — erections become less predictable and less firm. Even one week of five-hour nights measurably hurts hormonal and vascular markers in healthy men.
Why does this matter for men?
Men optimize supplements while sleeping six hours — the highest ROI lever is ignored.
What causes this?
- Late screens and alcohol.
- Inconsistent wake times.
- Untreated sleep apnea — snoring and daytime fog.
What should you do next?
- Fixed wake time for 14 days.
- Cut alcohol within 3 hours of bed.
- Screen sleep apnea if you snore and wake unrefreshed.
