Sleep Guides for Better Understanding and Better Sleep
Explore practical sleep information, research-based explanations and useful strategies for understanding your sleep.
From insomnia and sleep apnea to sleep supplements and Apple Watch sleep tracking, our goal is to help you make sense of the science.
Welcome to the MySleepPilot Guide Library. Whether you're struggling with sleep, trying to understand your sleep tracker, or researching a popular sleep supplement, you'll find useful information here.
Our articles emphasize clear explanations, practical understanding and the difference between promising research and well-established treatments.
Understanding Sleep: The Foundations
Start here to understand how sleep works, why it matters and how it changes throughout life.
Body Clock Basics
Learn how your internal clock, light exposure and daily timing help regulate sleep and wakefulness.
Understand Your Body Clock →Sleep and Aging
Explore how sleep patterns, timing and sleep architecture can change with age, and what changes may deserve attention.
Read Sleep and Aging →Healthy Sleep Habits
Understand the role of daily routines, light, exercise, bedroom conditions and consistent sleep timing.
Explore Healthy Sleep Habits →Insomnia, Nighttime Awakenings and Poor Sleep
Difficulty falling asleep, waking repeatedly and feeling tired after a full night are not always the same problem. These guides explore possible explanations.
Insomnia Basics
Learn what insomnia is, why it can become persistent and how evidence-based treatments such as CBT-I fit into the picture.
Read Insomnia Basics →Why Am I Waking Up at Night?
Explore common reasons for waking during the night, including sleep patterns, medical conditions and environmental factors.
Explore Nighttime Awakenings →The 2 A.M. Plan
A practical approach to handling nighttime wakefulness without turning a difficult night into an extended struggle.
Read the 2 A.M. Plan →Why Am I Still Tired After Sleeping?
Learn why time spent asleep doesn't always translate into feeling rested the next morning.
Explore Possible Causes →Sleep Apnea, Sleep Studies and Getting Help
Some sleep problems require medical evaluation rather than another supplement or a new bedtime routine.
Sleep Apnea Basics
Understand what sleep apnea is, common warning signs and why disrupted breathing can affect sleep quality and daytime health.
Read Sleep Apnea Basics →Sleep Study Basics
Learn what happens during a sleep study, what different tests measure and how testing can help identify sleep disorders.
Understand Sleep Studies →When to Get Professional Sleep Help
Not every bad night requires a medical appointment, but persistent insomnia, significant daytime sleepiness, suspected breathing interruptions and other symptoms may deserve further evaluation.
Learn When to Seek Help →Apple Watch Sleep Tracking and Sleep Stages
Understand what your sleep tracker reports, what its measurements mean and where the technology has limitations.
Understanding Apple Watch Sleep Data
Learn how Apple Watch estimates sleep, what its stage categories represent and how to interpret the information realistically.
Read the Apple Watch Sleep Guide →Apple Watch Sleep Translator
Enter your Awake, REM, Core and Deep sleep totals to receive explanations and context for your nightly results.
The tool also discusses the limitations of wearable sleep-stage accuracy.
Try the Sleep Translator →A useful reminder: Consumer sleep trackers estimate sleep stages. They do not directly measure brain waves in the way a clinical sleep study does.
Looking at broader trends and how you feel during the day is often more useful than worrying about one night's Deep or REM score.
Sleep Supplements and Melatonin
Explore the science behind popular sleep supplements, their possible benefits, side effects and important limitations.
Sleep Supplements: What Does the Research Really Say?
A detailed examination of melatonin, magnesium, apigenin, glycine, L-ornithine, taurine and Unisom.
Includes human research, potential benefits, side effects, medication interactions and supplement quality.
Read the Sleep Supplements Guide →Melatonin Basics
Understand what melatonin actually does, why timing matters and how its role in circadian regulation differs from that of conventional sleeping pills.
Read Melatonin Basics →Sleep Medication Safety and Brain Health
Understand the risks of common over-the-counter sleep medications, particularly those with anticholinergic properties.
Benadryl, Unisom and Dementia Risk: What the Research Actually Shows
Diphenhydramine and doxylamine are common sedating antihistamines, but both have important anticholinergic effects.
This in-depth article examines their effects on memory, attention, digestion, bladder function and alertness.
It also explores research into long-term cumulative anticholinergic exposure and dementia, explaining what the studies found and what they cannot prove.
Read the Anticholinergic Medication Guide →Sleep Techniques and Practical Experiments
Explore methods intended to help people fall asleep or return to sleep, with attention to what the research does and doesn't establish.
The Eye-Movement Sleep Technique
Andrew Huberman discussed an eye-movement technique on the Diary of a CEO podcast as a possible way to help with falling asleep.
Learn how the technique is performed and why its proposed scientific explanation should be distinguished from direct clinical proof of effectiveness.
Explore the Eye-Movement Technique →What to Do When You Wake at 2 A.M.
A companion nighttime approach focused on responding calmly to wakefulness and avoiding behaviors that can reinforce the struggle to sleep.
