Sleep Health Guide: How to Sleep Better

What sleep health means

Sleep health is broader than “eight hours.” A person can spend enough time in bed but sleep poorly because of repeated awakenings, an irregular schedule, substances, pain, stress, a body-clock mismatch or an untreated sleep disorder. Another person may sleep continuously but still obtain too little sleep because work, caregiving or habits restrict the opportunity.

A useful review considers six connected dimensions:

No single dimension diagnoses a disorder. Together, they give a clearer picture of what needs attention.

• Duration: whether there is enough actual sleep for age and individual need.
• Timing: whether sleep occurs at a time that fits the body clock and daily responsibilities.
• Regularity: how much bedtime and wake time vary across workdays, weekends and shifts.
• Continuity: whether sleep is repeatedly interrupted or difficult to maintain.
• Satisfaction and restoration: whether sleep feels reasonably refreshing rather than consistently poor.
• Daytime function: alertness, attention, mood and the ability to drive or work safely.

How Canadians sleep

• Insomnia is common. In a 2023 national survey of 4,037 adults, about 1 in 3 had insomnia symptoms and about 1 in 6 met the criteria for insomnia disorder (Morin et al., Sleep Medicine, 2024). See our insomnia guide.
• Sleep aids are widely used. Almost half of adults (46%) had used something to help them sleep in the past year. Natural or over-the-counter products are the most common, followed by cannabis and prescription medicines (same study).
• Sleep differs across groups. A study of 39,346 adults in the 2021 Canadian Community Health Survey found that women reported nighttime insomnia more often than men (23% vs 15%), that people with lower incomes tended to sleep worse, and that sleep problems varied by background, immigration status and sexual orientation (Chaput et al., Sleep Health, 2024).

How much sleep do you need?

Sleep need changes across the lifespan and varies between people. Most adults should allow at least seven hours regularly, while children and teenagers generally need more. Time in bed is not identical to time asleep, and repeatedly extending time in bed does not solve every cause of fatigue.

Use How Much Sleep Do You Need? for age-based guidance and a practical way to compare sleep opportunity with daytime function.

Timing and the body clock

The circadian system helps coordinate sleepiness and alertness across the day. Light is a major timing signal, but activity, meals, work schedules and social routines also contribute. A late or irregular schedule can create difficulty even when total sleep time appears adequate.

Morning light and consistent wake time often help anchor a daytime schedule, but standard advice must be adapted for night work, rotating shifts and unusually early starts. Read Circadian Rhythm: Understanding Your Body Clock or the Shift Work and Sleep guide for those situations.

Sleep quality and continuity

Good-quality sleep is not perfectly uninterrupted sleep. Brief awakenings can occur normally, especially with age. The concern is a repeated pattern of long awakenings, difficulty returning to sleep, choking or gasping, pain, uncomfortable legs, unusual behaviour or waking unrefreshed.

Consumer trackers can estimate patterns, but their scores and sleep stages are not a diagnosis. Use them as context: look for repeated changes that match how you feel, and bring the exact device and trend to a healthcare conversation when needed.

Habits and environment that support sleep

The most useful sleep habits create enough opportunity and reinforce a repeatable rhythm:

These are supports, not tests of discipline. Choose the change that matches the actual barrier. Explore Sleep Hygiene, How to Build a Bedtime Routine and The Best Bedroom Environment for Healthy Sleep for focused guidance.

• keep wake time reasonably consistent;
• allow enough time for sleep rather than borrowing from it;
• obtain suitable daytime light and activity;
• make the bedroom dark, quiet, comfortable and appropriately cool;
• create a manageable wind-down rather than demanding instant sleep;
• consider the timing and amount of caffeine, alcohol and nicotine;
• reduce late work, emotionally activating content and bright light when they delay sleep; and
• use naps deliberately so they help alertness without repeatedly displacing nighttime sleep.

Anchor the morning

A consistent wake time, appropriately timed morning light and daytime activity help organize the sleep-wake cycle. Large weekend shifts can make the next workday harder. If the preferred sleep period conflicts with work, school or caregiving, the circadian rhythm guide explains how timing cues interact.

Build an evening transition

Lower room and screen brightness, close demanding work, prepare essential items for tomorrow and choose a calm activity. A short sequence is easier to repeat than an elaborate wellness checklist. Use the bedtime routine guide for a flexible 60–30–10-minute plan.

What to do when you cannot sleep

Do not try harder, repeatedly check the time or stay in bed becoming increasingly frustrated. Keep light low and use a quiet activity until sleepiness returns. For persistent insomnia, stimulus control and sleep restriction are parts of cognitive behavioural therapy for insomnia and are best used within an appropriate treatment plan rather than improvised from a short tip.

Supplements and sleep products

“Natural” does not mean universally safe or effective. Melatonin timing and product content matter, and sedating products can interact with medicines, pregnancy, alcohol, driving and health conditions. Ask a pharmacist or healthcare provider before adding a sleep product, especially for children or ongoing use.

For Canadian rules on melatonin, including the June 2026 prescription requirement for anyone under 18, see melatonin in Canada.

Find the right starting point

The main symptom usually determines the most useful next page.

Try a two-week sleep-health check

For two weeks, record only information that will help answer a question:

Choose one or two changes that fit the clearest barrier and define them precisely. Compare the overall pattern rather than judging one night. A sleep record can support a clinical conversation but cannot diagnose insomnia, sleep apnea or another disorder.

• approximate bedtime, estimated sleep onset and final wake time;
• long awake periods and whether the cause was clear;
• naps, caffeine and alcohol timing;
• work shifts, major schedule changes and unusual stress or illness;
• snoring, gasping or breathing pauses reported by another person;
• morning restoration and sleepiness at two or three consistent daytime points; and
• any driving, work or near-miss safety concern.

When healthy habits are not enough

Sleep hygiene cannot reliably treat every sleep disorder. Seek an assessment when there is:

Start with the Sleep Apnea Symptoms hub when breathing symptoms are present, or Why Am I Always Tired? when fatigue is the main concern.

• persistent difficulty falling asleep, staying asleep or waking too early despite adequate opportunity;
• loud snoring with witnessed breathing pauses, choking or gasping;
• severe or uncontrollable daytime sleepiness;
• uncomfortable urges to move the legs or repeated limb movements;
• unusual movements, behaviours, confusion or injury during sleep;
• a body-clock pattern that repeatedly conflicts with required sleep and wake times;
• persistent fatigue despite adequate sleep opportunity; or
• a sleep problem associated with pain, breathing disease, pregnancy, menopause, medicines, substance use or another health condition.

Sleep health through changing circumstances

Sleep can change with age, pregnancy, menopause, shift work, caregiving, travel, illness, pain and mental-health concerns. The correct response is not always stricter habits. Sometimes the priority is more sleep opportunity, accommodation of a temporary life stage, treatment of another condition or assessment for a sleep disorder.

Advice should be adapted to the person’s abilities, living situation, work and access to care. If a strategy creates distress, worsens safety or conflicts with medical guidance, stop the experiment and seek appropriate advice.
