Myths vs facts: Testosteron and sleep

Testosterone and sleep have a bidirectional relationship. Fact: Sleep deprivation significantly lowers testosterone – even one week of 5 hours per night can reduce levels by 10–15%. Conversely, low testosterone can impair sleep quality, increasing nighttime awakenings and reducing deep sleep. Myth: Testosterone therapy cures sleep apnea. In reality, it may worsen obstructive sleep apnea, especially if untreated. Another myth: A single morning testosterone test is sufficient for diagnosis. Testosterone follows a circadian rhythm; multiple morning samples are needed for accuracy. Consumer tests (e.g., MyBody-X Men's Wellness Check) provide only a snapshot and are not diagnostic. For sleep issues and suspected hormonal imbalance, consult a physician for repeated lab work and possibly a sleep study.
