There is no shortage of advice on how to sleep better.
Buy blackout curtains. Take magnesium. Stop looking at your phone. Start meditating. Get morning sunlight. Tape your mouth shut. Drink something with ashwagandha in it. Buy a $500 device that tells you how badly you slept.
Some of that advice has merit. Some of it is mostly good marketing.
The frustrating part is that the things most likely to improve sleep are usually much less exciting. They are also largely free.
Sleep is not just time when the body shuts down for the night. It plays an important role in memory, mood, metabolism, cardiovascular health and everyday functioning, and most adults need at least seven hours a night on a regular basis.
But getting seven or eight hours in bed and actually sleeping well are not necessarily the same thing. If you regularly lie awake for an hour, wake repeatedly through the night or feel exhausted despite giving yourself plenty of time to sleep, the answer may be less about chasing the newest sleep hack and more about getting the basics right.
Your body likes a schedule, even if you don’t
Going to sleep and waking up at roughly the same time every day might be the least glamorous sleep advice ever given.
It is also one of the recommendations that shows up again and again in guidance from both the CDC and National Heart, Lung, and Blood Institute. A regular sleep-wake schedule helps reinforce the body’s circadian rhythm, the internal system that influences when you feel awake and when you start feeling ready for sleep.
The wake-up time may actually be the easier place to start.
If your bedtime varies because some nights you’re simply not tired yet, keeping your morning alarm relatively consistent still gives your body a reliable anchor. That includes weekends — although nobody is suggesting your Saturday morning needs to operate with military precision.
The bigger issue is swinging wildly between schedules. Sleeping from 11 p.m. to 7 a.m. during the week and then staying awake until 3 a.m. every weekend is effectively asking your internal clock to keep changing time zones.
Consistency is boring. Your circadian rhythm loves boring.
Caffeine lasts longer than your coffee
There is a reason you can drink coffee after dinner and insist it “doesn’t affect you” while also scrolling through your phone at 1:13 a.m. wondering why you aren’t tired.
Caffeine can remain active for hours. NHLBI notes that its effects may last as long as eight hours, although people differ considerably in how quickly they metabolize it.
That doesn’t mean everyone needs to stop drinking coffee at noon.
It does mean that if you’re struggling to fall asleep, your 4 p.m. iced coffee is an extremely easy variable to test before purchasing another sleep supplement.
Try moving your last caffeine earlier for a week or two and see what happens. Coffee, tea, energy drinks, pre-workout and even chocolate can contribute caffeine, so “I only had one coffee” does not always tell the whole story.
And while we’re ruining evening beverages, alcohol isn’t particularly helpful either.
A drink can make you feel sleepy initially, which is why alcohol sometimes gets mistaken for a sleep aid. But it can also contribute to lighter, more disrupted sleep and make waking during the night more likely.
Passing out faster and sleeping better are not the same thing.
Your phone isn’t the only problem. Light is.
Phones tend to get all the blame for bad sleep, but the issue is slightly more complicated than “blue light bad.”
Light itself is one of the strongest signals used by the body to regulate the sleep-wake cycle. Evening exposure to artificial light can suppress melatonin and delay signals associated with sleep, while daytime light helps reinforce the opposite side of that rhythm.
That means dimming your environment before bed can matter.
You don’t necessarily need to exile every electronic device from your house at sunset. The CDC recommends turning off electronic devices at least 30 minutes before bed, while NHLBI suggests using the hour before sleep for quieter activities and reducing bright light exposure.
There is also a behavioural side that is impossible to ignore.
Your phone contains work emails, breaking news, group chats, TikTok, Instagram and an infinite supply of things capable of making “I’ll just look for five minutes” turn into 45.
Sometimes the problem isn’t that your iPhone secretly destroyed your melatonin. You just never gave your brain a chance to stop doing things.
Make the bedroom good at its one main job
A bedroom doesn’t need to look like a wellness retreat.
It does help if it is dark, quiet, cool and comfortable. That’s one of the most consistent pieces of advice from public-health sleep guidance.
Blackout curtains can help if exterior light is an issue. Earplugs or white noise can make sense if your environment is loud. If your room feels like a sauna every night, turning the temperature down is probably more useful than buying another pillow mist.
The basic idea is to remove things that repeatedly wake you or make you uncomfortable.
The same logic applies to your bed. If you spend hours working, eating and watching television in it every day, the association between bed and sleep can get a little blurry. This becomes particularly important for people dealing with insomnia; one part of cognitive behavioural therapy for insomnia involves strengthening the relationship between bed and sleep rather than spending long stretches awake in bed.
Which brings us to an important point: sleep hygiene can help, but it isn’t a cure for every sleep problem.
Exercise helps. You don’t need to destroy yourself.
Regular physical activity is another habit consistently associated with healthier sleep, and both the CDC and NHLBI recommend staying active during the day.
You do not need to schedule a two-hour workout specifically to earn sleep.
Walk. Strength train. Cycle. Take a class. Do something you will actually keep doing.
Timing can matter more for some people than others. If a hard late-night workout leaves you feeling wired, experiment with moving it earlier rather than deciding that evening exercise is universally terrible.
The larger point is that sleep is connected to what happens during the other 16-ish hours of your day too.
You cannot optimize your way around an actual sleep disorder
This is the part that gets lost when sleep becomes wellness content.
If you have persistent insomnia, basic sleep habits may not be enough. Cognitive behavioural therapy for insomnia, or CBT-I, is generally recommended as a first treatment for long-term insomnia and uses specific behavioural and cognitive techniques to improve sleep.
There are also sleep problems that a perfect bedtime routine isn’t going to fix.
Loud habitual snoring, gasping or choking during sleep, breathing that repeatedly stops and starts, or significant daytime sleepiness can be symptoms of sleep apnea and are worth discussing with a healthcare provider.
No amount of lavender spray is going to outsmart an airway problem.
And if you routinely give yourself enough opportunity to sleep but still wake up feeling awful, keeping a simple sleep diary can be useful. NHLBI even provides one designed to track sleep times, caffeine, alcohol, medication and daytime sleepiness — exactly the kind of information that can reveal patterns or give a clinician something more useful than “I sleep terribly.”
So, what actually matters?
You don’t need a 14-step nighttime routine.
Give yourself enough time to sleep. Try to keep your wake and sleep times relatively consistent. Get some daylight and movement during the day. Pay attention to how late you’re drinking caffeine. Don’t rely on alcohol to knock yourself out. Turn the lights down and give your brain some distance from whatever is happening on your phone.
Make your bedroom somewhere you can actually sleep.
Then do those things consistently enough to find out whether they work.
That last part is usually where sleep advice falls apart. We want something we can take tonight that will fix everything by tomorrow morning. Unfortunately, most of the science points back toward habits repeated often enough that the body starts to know what to expect.
Not particularly sexy.
Still probably more useful than protein-infused sleep water.
