Shift Work and Sleep: Surviving Nights and Rotating Schedules

Shift work asks your body to do something it’s fundamentally not designed to do: be alert and functional during the biological night, and sleep during the biological day.

Waking Up to Pee at Night (Nocturia): Causes and What Actually Helps

It’s 3 a.m. and you’re awake again, making the familiar trip to the bathroom. Maybe it happens once a night. Maybe two or three times.

ADHD and Sleep: Why Adults With ADHD Sleep Differently

For most of ADHD’s history as a recognized condition, sleep problems were treated as a side effect — maybe medication-induced insomnia, maybe stress from the chaos of unmanaged ADHD, maybe just an unrelated coexisting issue.

Circadian Rhythm for Productivity: Scheduling Work Around Your Biology

Most people schedule their work around their calendar, their meetings, and the demands of others — almost never around their own biology. They do their hardest cognitive work whenever there’s a gap, answer email during their sharpest hours, and wonder why some tasks feel effortless one day and impossible the next. The missing variable

Best Timing for Melatonin Internationally: The Direction-Specific Protocol

Walk into any drugstore and you’ll find melatonin in the sleep aid section, sold in doses of 3, 5, 10, even 20 milligrams. The marketing is implicit: melatonin is a sleeping pill.

HRV and Sleep Quality: What the Numbers Actually Mean

If you wear an Oura ring, a Whoop, a Garmin, or any modern sleep tracker, you’ve seen the HRV number. Heart rate variability. It goes up on good days and down on bad ones, and the app tells you whether you’re “recovered” or should “take it easy.” Most people glance at it, feel either reassured

Sleep and Decision Making: The Hidden Performance Cost of Sleep Debt

Here’s the most dangerous fact about sleep deprivation and decision-making: you can’t feel the impairment. Research has repeatedly shown that as people become sleep-deprived, their cognitive performance declines measurably while their self-assessment of their performance stays roughly the same.
