Your sleep problem may begin hours before you get into bed.
The Night Audit is a whole-day inventory. It is not a diagnostic test. It helps you notice the inputs, habits and conditions worth paying attention to before assuming the answer lives in a stronger sleep product.
Timing
When did you wake up? Nap? Get into bed? Has your schedule shifted recently?
Light and technology
How much daylight did you get? How bright was the evening? What entered the night through your phone, laptop or television?
Inputs
When were your last caffeine, nicotine and alcohol exposures? When did you last eat a large meal?
Body
Movement, exercise, pain, temperature, restlessness and physical comfort can all belong in the picture.
Mind and emotion
What unfinished work, relationship tension, financial concern, anticipation, grief, excitement or decision followed you toward bed?
Environment
Noise, temperature, light, partner, children, pets and interruptions matter too.
When this should leave the Held lane
Persistent sleep difficulty, significant daytime sleepiness, loud frequent snoring, waking while gasping or short of breath, or other concerning symptoms deserve evaluation by a healthcare professional. A consumer wellness tool should not try to explain those away.
Before asking what to take tonight, ask what happened today.
Evidence base
NIH sleep guidance discusses regular sleep timing, light exposure, caffeine, nicotine, alcohol, meals, physical activity, bedroom conditions and stress as relevant sleep factors. The Night Audit organizes those factors into a usable reflection rather than claiming to diagnose their effects in an individual.
