I tried AYO+ Blue Light Therapy Glasses to help combat my crushing morning fatigue — here's how I feel after 3 months

A TG sleep tech tester sits in bed wearing the AYO+ Light Therapy Glasses soon after waking to fine-tune her circadian rhythm to reduce morning grogginess (sleep inertia) and boost energy.

I'm a Certified Sleep Coach but early motherhood means I haven’t had a good night’s sleep in nearly four years. Most mornings I battle with sleep inertia — that dense, groggy feeling when your brain refuses to reboot. I’ve been relying on caffeine for an energy boost, but it’s interfering with my sleep (caffeine has a half-life of up three to seven hours in adults).

To break the cycle, I decided to stop propping up my morning brain with caffeine and start biohacking it instead. That’s how I ended up testing the AYO+ Light Therapy Glasses (from $249/£249 at Ayo)—lightweight phototherapy frames that use blue-enriched light to fine-tune my circadian rhythm.
