How to Sleep Better
Learn how to fall asleep faster, stay asleep longer, and wake up feeling rested. Covers routines, environment, and the habits that actually make a difference.
We used to think being bad at sleeping was just a personality trait. Some people sleep well, some people lie awake staring at the ceiling wondering if they remembered to lock the front door. We assumed we were the second type and that was that.
Turns out a lot of it is behavioral rather than fixed. The things you do during the day and in the hours before bed have a large effect on how quickly you fall asleep, how deeply you sleep, and how you feel in the morning. Some sleep problems are medical, and the end of this guide covers when to stop adjusting habits and see a doctor.
The CDC reports that roughly one in three American adults does not get enough sleep on a regular basis. That is defined as less than seven hours per night. The consequences are well-documented: impaired concentration, weakened immune function, increased risk of chronic conditions, and mood changes that make everything harder.
Sleep hygiene, the habits and environment around sleep, is something you can improve starting tonight. None of these changes require medication, expensive mattresses, or major lifestyle overhauls. They are small adjustments that add up to significantly better rest.
Set a consistent sleep and wake schedule
Go to bed and wake up at the same time every day, including weekends. This is the single most effective thing you can do for your sleep. Your body has an internal clock (circadian rhythm) that regulates when you feel sleepy and when you feel alert. Keeping a consistent schedule trains this clock to initiate sleep at the right time. When you stay up two hours later on Friday and sleep in on Saturday, you give yourself social jet lag, which is exactly what it sounds like. By Sunday night, your body does not know when it is supposed to be tired, and Monday morning is miserable. Pick a wake-up time and stick with it. Your body will start getting sleepy at the right time on its own within a week or two.
Good to know: If you can only change one thing, make it your wake-up time. Waking up at the same time every day is more important than going to bed at the same time, because the morning anchor sets the rest of your circadian rhythm.
Make your bedroom dark, cool, and quiet
Three things decide whether your bedroom helps or hinders. Start with temperature. The ideal bedroom temperature for sleep is between 60 and 67 degrees Fahrenheit (15 to 19 degrees Celsius). Your body needs to drop its core temperature to initiate and maintain sleep. A warm room fights this process. Darkness is the second factor. Any light in your bedroom can interfere with melatonin production, especially blue and white light from electronics. Use blackout curtains or a sleep mask. Cover or remove any electronics with LED indicator lights. For noise, use earplugs or a white noise machine if you live somewhere loud. A fan serves double duty by creating white noise and keeping the room cool.
Build a wind-down routine
Your brain needs a transition period between being awake and being asleep. Starting 30 to 60 minutes before bed, do the same relaxing activities in the same order each night. This could be reading a book (not on a screen), stretching, taking a warm shower, or making a cup of herbal tea. The specific activities matter less than the consistency. When your brain recognizes the pattern, it starts releasing melatonin and preparing for sleep before you even get into bed. A warm shower or bath is particularly effective because the rapid cooling of your body afterward mimics the natural temperature drop that signals sleep.
Cut screen time at least one hour before bed
Screens emit blue light that suppresses melatonin production, but the light is only part of the problem. The content on screens is stimulating. Social media, news, work emails, and even entertaining videos keep your brain engaged and alert when it should be winding down. Put your phone in another room at least one hour before bed. If you use your phone as an alarm, buy a cheap alarm clock and charge your phone in the kitchen. The first few nights without your phone in the bedroom will feel strange. Give it a week before you judge whether it helped.
Heads up: Night mode and blue-light glasses help a little with the light issue, but they do not address the stimulation problem. Scrolling through social media with a warm-toned screen is still keeping your brain wired. The best screen filter is putting the phone in another room.
Watch what you eat and drink after mid-afternoon
Caffeine has a half-life of five to six hours, which means half of the caffeine from your 3 PM coffee is still in your system at 9 PM. Cut off caffeine by early afternoon, or noon if you are sensitive. Alcohol might make you feel drowsy, but it disrupts sleep architecture later in the night. It suppresses REM sleep, which is the deep, restorative stage your brain needs. If you drink, stop at least three hours before bed and keep it moderate. Eating a large meal close to bedtime can also disrupt sleep because your digestive system keeps your body active when it should be slowing down. Finish dinner two to three hours before bed. If you need a late snack, keep it small and avoid sugar.
Get bright light during the day
This sounds like it has nothing to do with sleep, but it is one of the most important factors. Exposure to bright light during the day, especially in the morning, strengthens your circadian rhythm and makes your body produce more melatonin at night. Aim for 15 to 30 minutes of outdoor light within an hour of waking up. A morning walk works, so does eating breakfast by a window, and so does standing outside with your coffee. On cloudy days, outdoor light is still significantly brighter than indoor lighting. Even overcast daylight measures around 10,000 lux, while a well-lit office is only about 500 lux. If you work indoors all day with limited natural light, a light therapy lamp on your desk can help.
Handle racing thoughts with a brain dump
If you lie in bed with your mind racing through tomorrow's to-do list, unresolved conversations, or random worries, try a brain dump. Keep a notepad on your nightstand. Before turning off the light, spend three to five minutes writing down everything on your mind. To-do items, worries, ideas, things you need to remember. Get it all out of your head and onto paper. A 2018 study published in the Journal of Experimental Psychology found that participants who wrote a to-do list before bed fell asleep significantly faster than those who wrote about completed tasks. Writing things down tells your brain that the thought is captured and can be addressed tomorrow. It does not need to keep rehearsing it.
Better sleep does not happen all at once. It is the result of consistent habits that create the right conditions for your body to do what it already knows how to do. Pick two or three changes from this guide and implement them tonight. A consistent wake-up time, screens off an hour before bed, and a cooler bedroom temperature are the three that change the most for the least effort. Give it two weeks. Sleep habits take time to shift because your circadian rhythm adjusts gradually, not overnight. If you are still struggling after a month of consistent sleep hygiene, talk to a doctor. There are treatable conditions like sleep apnea and restless leg syndrome that no amount of good habits will fix.
Questions we get asked about this
Answers from experience, not a textbook.
The National Sleep Foundation recommends seven to nine hours for adults aged 18 to 64, and seven to eight hours for adults over 65. The right amount varies by individual. Some people function well on seven hours while others need nine. The best indicator is how you feel during the day. If you need caffeine to stay alert, feel drowsy during afternoon meetings, or fall asleep within minutes of sitting down, you are probably not getting enough.
Short naps of 20 to 30 minutes before 2 PM are generally helpful and do not interfere with nighttime sleep. Longer naps or naps later in the day can reduce your sleep drive and make it harder to fall asleep at night. If you are struggling with nighttime sleep, avoid napping entirely for two weeks to rebuild sleep pressure. Once your nighttime sleep improves, you can reintroduce short early-afternoon naps if you need them.
Melatonin supplements can help with the timing of sleep but not the quality or duration. They are most effective for jet lag or shifting your sleep schedule (for example, when adjusting to a new time zone or a new work schedule). For general insomnia, the evidence is modest. The dosage matters, and the common mistake is taking too much. Research suggests that 0.5 to 1 mg is effective, while most over-the-counter supplements contain 3 to 10 mg. Higher doses can cause grogginess the next day and may actually disrupt your natural melatonin production. Talk to a doctor before using it long-term.
Get up. Do not lie in bed tossing and turning because your brain starts associating the bed with being awake and frustrated. Go to another room, do something quiet and non-stimulating in dim light (reading a physical book, light stretching, listening to calm music), and return to bed only when you feel sleepy. This technique is called stimulus control and it is one of the most evidence-based treatments for insomnia. It trains your brain to associate the bed exclusively with sleep.
