A study published in the Journal of Clinical Endocrinology & Metabolism found that men with higher urinary phthalate metabolites showed testosterone reductions of 10–34% compared to those with lower exposure — across multiple age groups including men 40–60.
"We found evidence that reduced levels of circulating testosterone were associated with increased phthalate exposure in several key populations, including men and women ages 40–60."

Put your phone in another room before you go to sleep. Not on airplane mode. Not face-down. In another room.
Here's why this matters: the blue light emitted by screens suppresses melatonin production, which delays the onset of deep sleep — the sleep stage during which 80% of your daily testosterone is produced. Poor sleep architecture is one of the fastest ways to tank your hormone levels.
