Insomnia

Symptoms & Logged Metrics · Reviewed August 2026

Definition

Insomnia is difficulty falling asleep, staying asleep, or getting sleep that feels restful, despite having enough time in bed, with knock-on effects the next day.[1] As a logged symptom it captures how sleep felt, and in menstruating people self-reported sleep quality often dips around menstruation.[2]

What an Insomnia Log Measures

Clinical references split insomnia into two main difficulties: trouble initiating sleep (lying awake at bedtime) and trouble maintaining it (waking during the night or too early), with daytime effects like sleepiness and irritability.[1] As a tracked symptom, an insomnia log records the felt side of sleep. That matters because felt sleep and measured sleep can disagree: research finds subjective sleep quality is lowest around menses even though sleep timing and composition stay relatively stable across the cycle in healthy women.[2]

How It's Measured

Diagnosis in clinical settings relies on self-reported history rather than a lab test.[1] Tracking works the same way: a nightly or morning rating of how well you slept, ideally next to device-measured sleep like sleep stages so the two views can be compared.

Why People Track Insomnia

Sleep complaints that cluster at a cycle phase only show up when sleep and cycle sit on the same chart. A diary study of 213 women found distinct patterns: some women's difficulty sleeping rose perimenstrually, some rose mid-cycle, and others showed no cyclical change at all.[3] That's a strong argument for tracking your own pattern rather than assuming the average applies to you. A few cycles of ratings answer which group you're in.

How Go Go Gaia Tracks Insomnia

Go Go Gaia logs sleep quality as a 1-click rating from 1 (very poor) to 5 (excellent), with a separate 1-to-5 log for how sleep-deprived you feel during the day. Both are charted against your cycle phase and shown alongside sleep duration and stages synced automatically from HealthKit, so you can see whether rough-feeling nights line up with a cycle phase, with shorter measured sleep, or with neither.

What the Research Shows

A review of menstrual-cycle sleep research found that subjective sleep quality is lowest around menses, while lab measures show the timing and composition of sleep remain relatively stable across the cycle in healthy women, apart from small luteal-phase changes such as reduced REM sleep.[2] The honest summary is that the felt change is better established than any objective one, the same split our sleep stages entry describes.

A two-cycle diary study of 213 women found self-reported difficulty sleeping followed different patterns in different women, perimenstrual for some, mid-cycle for others, and flat for the rest, with sleep difficulty tracking psychological and somatic symptoms reported at the same time.[3]

A review in Sleep Medicine Clinics adds one consistent thread: poorer sleep quality in the premenstrual phase and during menstruation is common in women who have premenstrual symptoms or painful menstrual cramps.[4]

Frequently Asked Questions

Educational information based on published sources. Not medical advice. For personal concerns, please consult your doctor.

Does the menstrual cycle affect sleep?

Research shows a split between how sleep feels and how it measures. Women report their worst subjective sleep quality around menstruation, yet lab studies find sleep timing and composition stay relatively stable across the cycle in healthy women.[2] Diary studies also show individual patterns differ, with some women reporting perimenstrual difficulty, some mid-cycle difficulty, and some no cyclical change.[3]

What counts as insomnia?

Clinical references define insomnia as difficulty initiating sleep, maintaining sleep, or getting sleep that feels restful, despite adequate opportunity to sleep, with daytime effects like sleepiness or irritability.[1] As an app log it's simpler: a record of nights when falling or staying asleep was hard.

Why log insomnia alongside cycle data?

Because sleep complaints that cluster at a particular cycle phase only become visible when both are on the same chart. A few cycles of ratings show whether your rough nights repeat premenstrually, mid-cycle, or at random, and pairing the rating with device-measured sleep data shows whether felt sleep and measured sleep tell the same story.
