Monday
Your bedroom, fixed
Light, temperature, sound and air, corrected one small change at a time.
The number one performance drug is free
I spent 10 years testing every sleep fix.
Here is the 20% that works.
Lights Out is a free nightly letter from Claire Ashton, a recovered insomniac turned sleep researcher. One small fix a night, backed by research, costing close to nothing.
Free forever. One letter a night. One click to leave.
Why this letter exists
Ten years of failure taught me which 20% is real.
Melatonin. Chamomile. Lavender spray. White noise machines. Every bottle on the shelf, and almost none of it moved the needle.
So I started testing properly. One change at a time, reading the trials instead of the labels, throwing out anything that only worked because I wanted it to.
It was never your fault, and it was never a discipline problem. The real fix is smaller and cheaper than they want you to believe.

The scorecard
Hack, or garbage? Pick one.
Sleepmaxxing has hundreds of millions of views, and 37% of American adults have already tried a viral sleep hack. Here is my verdict on the four you keep seeing.
Partly works
Tart cherry does carry natural melatonin, and the magnesium helps, but only in the right form. Most people reach for the cheapest one on the shelf, which is the one that does the least.
Risky, skip it
It can trigger panic, and it can quietly worsen undiagnosed sleep apnea. There is almost no clinical evidence behind what the videos promise.
Does nothing
The lactucarium concentration is so low you would need to drink a bathtub of it to feel anything. Charming idea, no effect.
Works, with one rule
Only amber or orange lenses do anything measurable. The clear lenses sold as blue light protection are mostly marketing.
The $0.80 secret
Eat two kiwis one hour before bed.
Taipei Medical University put it through a clinical trial. Four weeks later subjects were falling asleep 35% faster, sleeping 13% longer, and waking less in the night. No influencer pushes kiwis, because there is no brand deal attached to a piece of fruit. That is exactly why I trust it.
