Sleep better tonight: natural sleep tips from our RTs
Evidence-informed habits that help most people sleep better. The foundation, even for those already on CPAP or BiPAP.
Good sleep doesn't always need a machine. These evidence-informed habits help most people sleep better, and they're the foundation even for those already on CPAP or BiPAP therapy.
1. Keep a consistent sleep schedule
Going to bed and waking up at the same time every day, including weekends, is one of the most powerful sleep habits you can build. Consistency synchronises your body's internal clock (circadian rhythm), which makes falling asleep faster and waking more natural. Most people underestimate how much irregular timing costs them.
Even one night of shifted sleep timing can make the following nights harder. Resist the urge to "catch up" on weekends: sleeping in on Sundays often delays your body clock and makes Monday mornings worse, not better.
2. Manage your light exposure
Light is the primary signal that sets your body clock. Bright natural light in the morning (ideally within the first hour of waking) anchors your sleep timing for the night ahead. In the evenings, dimming lights and reducing blue-light exposure from screens in the hour or two before bed supports your body's natural melatonin rise.
Practical steps: open curtains or step outside shortly after waking; switch to warm, dim lighting after dinner; use night mode on your phone or put it away before bed.
3. Keep the bedroom cool, dark, and quiet
Your body's core temperature drops to initiate sleep. A cool bedroom, generally 18-20°C (Sleep Foundation guidance), supports that drop and helps most adults sleep more deeply. Blackout curtains or an eye mask block light that disrupts melatonin production; earplugs or white noise handle inconsistent sounds.
For those on CPAP or BiPAP: a cooler room also tends to reduce mask discomfort and condensation in the tubing.
4. Limit caffeine after 2pm
Caffeine works by blocking the adenosine receptors that build "sleep pressure" over the day. Its half-life in most adults is roughly 4 to 6 hours (FDA guidance), so a 3pm coffee still carries a meaningful load by bedtime. Cutting off caffeine at 2pm (or noon for sensitive people) gives your sleep pressure a chance to accumulate properly.
This includes coffee, tea, energy drinks, and some sodas. Decaf is not caffeine-free; it contains a small amount.
5. Build a wind-down routine
Your brain needs a transition signal before sleep. A consistent 30 to 60 minute wind-down routine (no screens, dimmed lights, a low-stimulation activity) gives it one. A physical book, gentle stretching, a warm shower, or quiet conversation all work. The specific activity matters less than the consistency.
Repeat the same sequence every night and your brain starts to read it as a "sleep is coming" cue. The warm shower has an added benefit: the body-temperature drop afterward can help initiate sleep onset.
6. Sleep positioning: side sleeping for Obstructive Sleep Apnea
For people with Obstructive Sleep Apnea, sleeping on your side (lateral position) produces fewer airway events and less snoring than sleeping on your back. When you lie supine, the tongue and soft palate tend to fall backward and partially block the airway. The lateral position keeps that from happening.
A sleep-positioning pillow can help you stay on your side through the night if you tend to roll back during sleep. Respyre carries one as part of our sleep hygiene service, an affordable starting point for people not yet on a CPAP machine. Learn more about our sleep hygiene service.
Our licensed RT will advise on whether positional therapy is appropriate for your situation.
7. Limit alcohol before bed
Alcohol may help you fall asleep faster, but it fragments sleep in the second half of the night and reduces REM sleep. For people with sleep apnea, it also relaxes throat muscles further and can worsen breathing events. Limiting alcohol, particularly in the two to three hours before bed, makes a meaningful difference to sleep quality.
8. Exercise regularly, but not right before bed
Regular physical activity improves sleep quality and duration. Moderate aerobic exercise done in the morning or afternoon tends to benefit sleep the most. Vigorous exercise in the hour or two immediately before bed can raise core temperature and heart rate in ways that delay sleep onset for some people. Find a timing that works for your schedule and repeat it.
Frequently asked questions
Melatonin helps regulate the body clock and may ease sleep onset, but it does not treat sleep apnea. Sleep apnea is a breathing disorder that requires clinical evaluation and, where appropriate, a CPAP or BiPAP machine. Our licensed RT will advise on your next steps.
For people with OSA, side sleeping (lateral position) produces fewer airway events than sleeping on the back, consistent with a systematic review of body position and OSA severity (PMC). A sleep-positioning pillow can help maintain the side position through the night. For people without OSA, the best position is the one that gives you comfortable, uninterrupted sleep.
Most adults are advised to aim for 7 to 9 hours per night (AASM/Sleep Research Society consensus). Individual needs vary; consistently waking unrefreshed despite 7+ hours may suggest an underlying sleep disorder worth evaluating. Our licensed RT will advise on your next steps.
For people diagnosed with sleep apnea, sleep hygiene complements CPAP or BiPAP therapy; it does not replace it. Good habits support therapy adherence and overall sleep quality, but they do not address the airway obstruction or brain-signalling issue that causes sleep apnea. Our licensed RT will advise on the right approach for your situation.
The most important factor is consistency. Your ideal bedtime is roughly 7 to 9 hours before your required wake time. Going to bed and waking at the same time every day helps synchronise your body clock and makes falling asleep easier over time.
