Good sleep is not just about hours in bed, the habits you build in the hour or two before bedtime matter just as much for how well you actually sleep.
1. Dim the Lights an Hour Before Bed
Bright light, especially blue-spectrum light from screens, suppresses melatonin production, the hormone that signals your body it is time to sleep. Dimming overhead lights and switching devices to night mode gives your body a clearer signal.
2. Keep the Room Cool
Most sleep research, including guidance from the CDC, points to a bedroom temperature around 65-68F (18-20C) as ideal for most adults, your core body temperature naturally drops to initiate sleep, and a cool room supports that process rather than fighting it.
3. Cut Off Caffeine Early
Caffeine has a half-life of roughly 5-6 hours, meaning a 3pm coffee can still have a meaningful amount active in your system at 9pm. See our Caffeine Calculator for a personalized cutoff guideline.
4. Have a Consistent Wind-Down Routine
Reading, light stretching, or journaling for 15-20 minutes signals to your brain that sleep is coming, the same way a consistent routine helps young children fall asleep more easily. Consistency, more than the specific activity, is what matters.
5. Avoid Large Meals and Alcohol Close to Bedtime
Eating a heavy meal or drinking alcohol within a couple hours of bed can disrupt sleep architecture, alcohol in particular tends to fragment sleep in the second half of the night even though it can make falling asleep initially easier.
6. Get Consistent Light Exposure During the Day
Morning sunlight exposure helps anchor your circadian rhythm, making it easier to feel sleepy at a consistent time each night. Even 10-15 minutes outside shortly after waking can help.
The Bottom Line
None of these habits work as a single magic fix, but stacked together consistently, they create the conditions your body needs to fall asleep faster and sleep more soundly.

Frequently Asked Questions
How long does it take for a bedtime routine to start working?
Many people notice a difference within 1-2 weeks of consistent practice, though building a strong habit fully can take longer.
Is it bad to check my phone right before bed?
The blue light and mental stimulation from scrolling can both interfere with falling asleep, night mode settings help somewhat, but stepping away from the phone entirely works better.
Does a warm bath before bed help or hurt sleep?
It can help, the drop in body temperature after getting out of a warm bath mimics the natural pre-sleep temperature dip, which may make falling asleep easier.
