Sleep Hygiene: Small Habits That Make Sleep Easier

 

Good sleep isn’t just luck or genetics. It’s mostly a set of repeatable behaviors that make it easier for your brain and body to do what they already want to do: cycle through deep, restorative sleep. That set of behaviors is often called sleep hygiene. It won’t cure every sleep disorder, but it will lower the friction that keeps many of us up at night.

 

How sleep works:

​

- You have two main systems: a circadian clock that runs on roughly 24 hours and is set by light, and a sleep-pressure system that builds “tiredness” the longer you’re awake.

​

- Morning light helps set your clock so you feel sleepy at night and alert in the morning. Bright light at night pushes your clock later.

​

- Body temperature follows a daily rhythm. You fall asleep more easily as your core temp drops; a cool bedroom and a warm bath or shower before bed can help that drop happen.

 

The big levers (the 80/20 of sleep hygiene):

​

- Keep a consistent schedule. Wake up at the same time every day, weekends included. A stable wake time is the strongest anchor for your clock.

​

- Get morning daylight. Within the first 1–2 hours after waking, get 10–30 minutes of outdoor light (longer if it’s overcast). If outdoors isn’t possible, use the brightest indoor light you have.

​

- Dim and warm your evening. About 2–3 hours before bed, reduce light intensity and shift to warmer tones. Avoid bright overhead lights; use lamps. If you need screens, turn brightness down and use night mode.

- Caffeine cut-off. Caffeine can linger 8–12 hours. As a rule of thumb, have your last caffeinated drink at least 8 hours before bedtime (earlier if you’re sensitive).

​

- Alcohol and nicotine. Both fragment sleep. If you drink, stop 3–4 hours before bed and hydrate. Avoid nicotine close to bedtime.

​

- Move your body. Aim for 150+ minutes of moderate exercise weekly. Most people tolerate light to moderate evening activity; very intense workouts close to bedtime can be too stimulating.

​

- Time your meals. Finish large meals 2–3 hours before bed. If hungry, choose a small, simple snack. Heavy, spicy, or high-fat meals late can cause reflux and wakefulness.

​

- Nap smart. If you’re struggling at night, avoid late or long naps. If you must nap, keep it to 10–30 minutes before mid-afternoon.

​

- Build a wind-down routine. Reserve 30–60 minutes for calming activities: reading paper pages, stretching, gentle yoga, a warm bath or shower, journaling, or a simple breathing practice. Repeat the same steps nightly to teach your brain the sequence.

​

- Make your bedroom a sleep cue. Cool (about 60–67°F or 15–19°C), dark, and quiet. Consider blackout curtains, a white-noise fan, and hiding the clock face. Keep the bed for sleep and sex only.

​

- Manage a racing mind. Do a “brain dump” list earlier in the evening. If worries pop up in bed, write them briefly on a notepad and revisit tomorrow. Try a body scan or slow breathing (for example, 4-second inhale, 6–8-second exhale).

​

- If you can’t sleep, don’t force it. After about 15–20 minutes awake in bed, get up and do something calm in dim light. Return to bed when sleepy. This retrains your brain to link bed with sleep, not tossing and turning.

 

What to do when you wake up at night:

​

- Keep lights very dim; avoid bright screens.

- Don’t clock-watch. Turn the clock away.

- If your mind is busy, try a simple script: “Thinking is normal; I’m safe; I’ll rest my body.” If wakefulness persists, get up briefly and read something low-stakes in dim light.

 

Travel, shift work, and social jet lag:

​

- For travel across time zones, shift your schedule 1–2 hours per day before you go, chase morning light at the destination, and dim evening light. Short, early-afternoon naps can help the first few days.

​

- For early shifts, get bright light on waking and keep evenings very dim. For night shifts, use bright light during the shift, wear sunglasses on the way home, sleep in a cave-dark room, and keep a short “anchor” sleep at the same time daily.

​

- On weekends, try to keep wake time within about an hour of weekdays. Sleep-ins feel good but can push your clock later and make Monday rougher.

 

Supplements, trackers, and myths:

​

- Melatonin helps shift the timing of sleep; it’s not a strong sedative. It’s most useful for jet lag or delayed sleep schedules. If you try it, small doses (often 0.3–1 mg) 4–6 hours before your target bedtime can be more “clock-shifting” than large doses at bedtime. Ask a clinician if you have medical conditions or take other meds.

​

- Magnesium, glycine, and similar supplements have mixed evidence. If you experiment, change just one thing at a time and track how you feel.

​

- Sleep trackers are best for spotting trends, not absolute numbers. Don’t chase the “perfect score.” If they make you anxious, take a break.

​

- Not everyone needs 8 hours. Most adults land somewhere between 7 and 9. Your best number is the one that leaves you feeling alert and functioning well.

- You can’t fully “bank” sleep, but catching up a bit after a short night is reasonable. Just avoid sleeping so long that you can’t fall asleep the next night.

​

- Evening exercise isn’t automatically bad. If you feel wired, move it earlier; if you sleep great after a 7 p.m. workout, keep it.

 

A 2-week reset plan:

Week 1

- Pick a consistent wake time and stick to it daily.

- Get outside light every morning. If you sit at a desk, work by a bright window when possible.

- Set a caffeine cut-off. If your target bedtime is 10 p.m., aim for no caffeine after 2 p.m. (earlier if needed).

- Create a 45-minute wind-down that you can repeat: tidy up, warm shower, stretch, read.

- Darken your bedroom and lower the temperature. Add white noise if outside sounds wake you.

- Keep a simple log: wake time, light exposure, caffeine timing, exercise, bedtime, total sleep time, and how you feel.

 

Week 2:

- Tighten consistency. Keep weekend wake time within an hour of weekdays.

- Tweak your “sleep window.” If you’re lying awake a long time, go to bed a bit later so you’re sleepier, but keep wake time the same. As sleep becomes more efficient, move bedtime earlier by 15 minutes every few nights.

- Refine the evening: dim lights 2 hours before bed; plan tomorrow earlier in the evening to cut bedtime rumination.

- If you’re still wide awake in bed, practice getting up for a quiet, dim-light activity until drowsy.

 

Special situations and quick fixes:

​

- Snoring partner or city noise: try white noise or earplugs; encourage evaluation for snoring that includes gasping or pauses.

- Pets and kids: if frequent disruptions are unavoidable, double down on naps earlier in the day (short power naps) and prioritize a rock-solid wake time.

- Allergies or reflux: reduce triggers in the bedroom, elevate the head of the bed slightly for reflux, and time meals earlier.

 

When to get help:

​

- Persistent trouble falling or staying asleep at least three nights a week for three months or more.

- Loud snoring with choking or gasping, morning headaches, or significant daytime sleepiness.

- Restless or uncomfortable legs at night, teeth grinding, or frequent nightmares.

- Mood changes, anxiety, or pain that interferes with sleep.

Evidence-based first-line treatment for chronic insomnia is cognitive behavioral therapy for insomnia (CBT-I), which a trained clinician can provide in person or via digital programs.

 

A simple checklist you can post on your fridge:

​

- Same wake time every day

- Morning daylight exposure

- Caffeine cut-off 8+ hours before bed

- Dim lights 2 hours before bed

- 45-minute wind-down routine

- Cool, dark, quiet bedroom

- Bed only for sleep and sex

- If awake >20 minutes, get up and reset

 

You don’t have to implement everything at once. Pick two or three changes, keep them for a week, then layer in the next. Consistency beats perfection, and small habits add up to better nights.
