Why apnea hurts hormones
Sleep apnea fragments deep and REM sleep — the windows where testosterone is produced. Untreated apnea is one of the most common hidden causes of low T in men over 35.
The signs
Loud snoring, witnessed pauses in breathing, morning headaches, waking unrefreshed, daytime sleepiness, excessive weight around the neck.
What to do
Get a sleep study (in-lab or validated home test). CPAP therapy restores testosterone toward baseline in many men within 3-6 months.
Frequently asked questions
- Can I have apnea at normal weight?
- Yes — anatomy matters as much as weight. Do not rule it out because you are lean.
- Will losing weight fix apnea?
- Often substantially, especially in overweight men. CPAP bridges the gap during weight loss.
