Because the pill erases the symptom without touching the cause. Sedation is not complete physiological sleep, and chronic insomnia almost always has roots in cortisol, hormones, glucose or habits. While the cause stays active, the dose stops working and the insomnia returns.
The right question is not "which pill makes me sleep", it is "why did my body unlearn how to sleep on its own". Sedating the brain and truly sleeping are different things: the sleep induced by some sedatives does not reproduce the full architecture of physiological sleep, and it is in the deep stages that the body repairs itself.
In Reactiva's insomnia data, with 267 responses, 96% of poor sleepers had already tried something, and the most tried item, by far, was medication: 3 in 4 had turned to it. The list includes anxiolytics and sleep aids used on people's own initiative or renewed for years without reassessment. If medication solved the cause, these people would not be filling out a form about insomnia.
The cycle the pill does not break
- •Chronic stress keeps cortisol high at night, when it should be at its minimum.
- •The body treats the night as a threat: light sleep, awakenings, a racing heart.
- •The pill forces sedation on top of the alarm that stays on. The alarm stays on.
- •Tolerance arrives, the dose climbs, and the cause remains intact.
Where the cause usually lives
High cortisol at night, a dysregulated thyroid, falling progesterone and estradiol in perimenopause, low testosterone in men, glucose swinging in the small hours, magnesium and vitamin D deficiencies, and the phone in bed telling the brain it is still daytime. It is almost always a combination, not a single cause. That is why treating one isolated piece fails.
The path that works
Investigate the whole system before any decision: late-night salivary cortisol when excess is suspected, TSH and free T4, estradiol and progesterone in women, testosterone in men, fasting insulin, and the sleep described in detail. With the cause mapped, sleep goes back to being a consequence. Important: anyone using sleep medication should not stop on their own, but reassess under medical supervision.

The answer is not one more isolated lab test. It is reading the system.
Medicine is one. The body does not divide itself into specialties: the model does. When each symptom goes to a different office and each doctor sees one piece, you spend years circling between referrals, holding reports and missing answers. In that back-and-forth, you lose time and health.
Precise diagnosis and treatment come from the opposite path: understanding everything and going deep into one patient. Sleep, hormones, weight, energy and mind interpreted together, because that is how the body works.
