1. Set a Consistent Wake-Up Time (Not Just a Bedtime)

Most advice focuses on when you go to bed. But sleep specialists say the more powerful anchor is your wake-up time. Waking at the same hour every day—including weekends—strengthens your circadian rhythm and makes it easier to fall asleep at the right time the following night.

If you currently sleep in on Saturdays and Sundays, try shifting your weekend wake-up time to within 30 minutes of your weekday time. Your body will thank you by Monday morning.

2. Dim the Lights 60 Minutes Before Bed

Light is the single most powerful signal your brain uses to determine whether it is time to be awake or asleep. Bright light in the evening—especially blue light from screens—suppresses melatonin production and delays sleep onset.

Sleep experts recommend reducing bright light exposure at least 30 to 60 minutes before bedtime. Practical steps include turning off overhead lights, using lamps with warm bulbs, and dimming your phone or tablet screen to its lowest setting.

3. Put Your Screens Away (Yes, Really)

The research on screen use before bed is consistent: smartphones, tablets, and laptops delay bedtime and reduce sleep quality. A 2025 study in Nature confirmed that evening light exposure acutely attenuates melatonin release and has phase-delaying effects on the circadian system.

If going fully screen-free feels unrealistic, try a “digital sunset” of at least 30 minutes. Use that time for a low-stimulation activity: reading a physical book, gentle stretching, or journaling.

4. Keep Your Bedroom Cool, Dark, and Quiet

Your body temperature naturally drops as you approach sleep. A cooler bedroom supports this process. The National Sleep Foundation recommends a thermostat setting between 60 and 67 degrees Fahrenheit (15.5 to 19.4 degrees Celsius) for most adults.

Darkness matters too. Even small light sources—a blinking charger, a streetlight through thin curtains—can interfere with melatonin production. Blackout curtains, sleep masks, and covering or removing light-emitting devices from your bedroom can make a measurable difference.

5. Watch Your Caffeine Cutoff (It Is Earlier Than You Think)

A 2025 randomized clinical trial published in the journal Sleep found that 400 mg of caffeine—roughly the amount in two large coffees—significantly disrupts sleep when consumed within 12 hours of bedtime. Even 100 mg (about one cup of coffee) can affect sleep if consumed within 4 hours of bed.

If you are sensitive to caffeine or struggle with sleep, consider setting your cutoff at 12 PM rather than 2 PM. This gives your body enough time to metabolize the stimulant before your head hits the pillow.

6. Be Honest About Alcohol

Alcohol is widely believed to help with sleep because it makes you feel drowsy. But a 2026 narrative review published in Nutrients confirms what sleep researchers have known for years: although alcohol may reduce sleep onset latency, it disrupts sleep architecture, suppresses REM sleep, increases fragmentation, and impairs breathing during sleep—particularly in the second half of the night.

The review concludes bluntly: alcohol should not be considered a sleep aid. If you do drink, earlier consumption (with food, several hours before bed) is less disruptive than a nightcap.

7. Do Not Lie in Bed Awake

This is the most counterintuitive tip on the list—and one of the most effective. If you have been awake in bed for more than 20 minutes, get up. Move to another room with dim light. Do something quiet and boring until you feel sleepy. Then return to bed.

This technique is called stimulus control, and it is a core component of Cognitive Behavioral Therapy for Insomnia (CBT-I). The goal is to break the association between your bed and frustration or wakefulness. Veterans Affairs clinical guidelines note that you must follow this rule consistently for 2 to 4 weeks to see an effect.

Frequently Asked Questions

How long should a nighttime routine be?

There is no strict rule, but sleep experts often suggest 30 to 60 minutes of wind-down time before bed. The key is consistency, not duration. Even a 15-minute routine practiced every night can train your brain to associate those actions with sleep.

What if I do not feel sleepy at my usual bedtime?

Follow the 20-minute rule: if you have been in bed for about 20 minutes and are not asleep, get up. Do something quiet in dim light until you feel sleepy, then return to bed. Do not force yourself to stay in bed awake.

Does exercise help with sleep?

Yes. A 2024 review in the European Journal of Applied Physiology found that regular exercise—including aerobic activity, resistance training, and mind-body exercises like yoga—can improve sleep quality, particularly for people with insomnia. Morning or afternoon exercise is generally preferable to intense workouts right before bed.

Is it okay to read on a tablet before bed?

Tablets emit blue light, which can suppress melatonin and delay sleep onset. If reading is part of your routine, a physical book or an e-reader with a warm, dim screen setting is a better choice than a phone or tablet on full brightness.
