5 Science-Backed Sleep Habits That Actually Work, According to Neurologists

Every month, more than 74,000 people search “how to fall asleep fast” on Google, hoping for that elusive trick to drift off quickly.

Here’s the plot twist: The most effective sleep habits have nothing to do with what happens in bed—and everything to do with what you do from the moment you wake up.

1. Prioritize Regularity Over Length

When it comes to improving sleep, most people focus on getting the recommended seven to nine hours a night. But sleep regularity—as in going to bed and waking up at consistent times—may be even more important than duration alone.

It’s important to get up “at the same time every day,” Dr. Douglas Kirsch, neurologist and medical director of Atrium Health Sleep Medicine, told The Epoch Times.

A 2018 study of Norwegian university students published in the Journal of European Psychology Students found that students who slept irregularly reported lower life satisfaction and more daytime tiredness, even when total sleep time was similar.

The same pattern showed up in a 2025 study of more than 700 middle-aged and older adults published in the Journal of Sleep Research, which found that people with irregular sleep schedules reported lower quality of life, even when they logged the same total hours of sleep. These people also reported worse mental and physical health scores.

And in a large-scale analysis of data from more than 300,000 adults, those with regular sleep routines got more restful sleep overall. Even chronotype, the natural preference for morning versus evening, didn’t override the effect: A late sleeper with a regular schedule slept better than an early sleeper with an irregular one.

The body’s restorative processes run on an internal clock that depends on timing, not just duration. So an irregular sleep schedule can lead to waking up groggy and sluggish in the morning despite spending the same number of hours in bed, much like jet lag.

Kirsch said that this consistency should extend to weekends as well. People often try to sleep longer on weekends to make up for lost sleep during the week, but doing so doesn’t undo the metabolic damage and only disrupts the body clock further.

2. Skip the Alarm Clock and Stop Snoozing

Many of us rely on alarm clocks to wake up, but this abrupt jolt isn’t good for us.

“When you’re awoken by an alarm clock, it shocks your body and brain awake, triggering a burst of the stress hormone cortisol,” Whitney Roban, who has a doctorate in clinical and school psychology and is a sleep expert, an author, and the founder of Solve Our Sleep, told The Epoch Times.

Normally, when you wake up without an alarm, your sleep cycle ends in a lighter stage, making the transition to wakefulness smoother and clearer, and you wake up feeling rested.

Waking up using alarms disrupts the natural waking process, causing you to wake up feeling tired. Snoozing won’t be able to remediate the disturbance and only causes you to drift into shallow, unstable sleep. Snoozing won’t be restorative because your brain is already anticipating the next interruption, Roban said.

“As a result, you miss out on the benefits of deep sleep and often wake up feeling even more groggy due to sleep inertia,” she said.

Sleep inertia is the heavy, foggy state that happens when you’re forced awake before your brain has naturally completed its transition out of sleep.

Sleep inertia and feeling tired from an incomplete sleep cycle can lead to daytime sleepiness, which leads to excessive snoozing and late naps—all of which chip away at nighttime sleep pressure and make it harder to fall asleep later.

Dr. Thien Thanh Dang-Vu, neurologist and director of the Sleep, Cognition & Neuroimaging Laboratory at Concordia University, advised limiting naps to 30 minutes or less, ideally in the early afternoon.

You can build sleep pressure with sustained wakefulness and doing cognitively stimulating or physically demanding activities during your waking hours.

3. Bask in Bright Morning Light

A key to improving sleep regularity is exposure to natural light. “Bright light in the morning is essential to our starting the sleep clock for the following night,” Kirsch said, adding that if possible, take a walk outdoors soon after waking. Five to 10 minutes of exposure is enough on a sunny day, but you may need closer to 10 to 15 minutes when it’s overcast.

Melatonin, the hormone that regulates your sleep-wake cycle, is closely tied to light exposure. That’s why getting natural light in the morning and reducing light at night helps signal to your body when it’s time to wake up—and when it’s time to sleep.

Research showed that exposure to bright artificial light within the first few hours after waking helped participants feel more alert in the morning and prepared people for sleep in the evening. This early light exposure reinforces your natural day-night rhythm and makes a steady sleep schedule easier to keep.

Exposure to bright light (such as sunlight) at midday helps stabilize your circadian rhythm, keeping you alert during the afternoon and helping you wind down at night.

Evening light has the opposite effect. Exposure to light in the evening mimics the properties of natural daylight, suppressing melatonin release, which may interfere with sleep. This includes things from room lights to electronic devices.

4. Journal Before Bed

During waking hours—especially on busy days—most of us don’t have time to reflect or process negative and anxious thoughts. But those unprocessed worries tend to catch up with us at night, often surfacing as we try to fall asleep or when we wake in the middle of the night.

“When we start worrying or ruminating at night, the brain activates the sympathetic nervous system,” Roban said, noting that the resulting rise in heart rate and blood pressure makes sleep even more difficult.

To help the brain wind down, Roban recommends journaling about an hour before bed to release intrusive thoughts and jot down the next day’s to-do list.

Writing things down signals to your brain that these concerns are captured and don’t need to be actively held in memory.

5. Stop Checking the Time

It’s common to glance at the clock to see how much sleep time is left, but tracking your rest in real time can backfire.

“Stop watching the clock during the night,” Kirsch said. “It’s not helpful and often makes sleep worse.” Clock-watching fuels anxiety and raises cortisol levels, making it even harder to fall asleep.

Checking the time can become a habit—and the more you do it, the more likely you are to wake up again during the night because you become more conscious of the time. Instead, Kirsch recommends keeping the bedroom dark and free of distractions and stimuli, which makes it easier to drift back to sleep.

While the improvements in your sleep may not be observable at first, consistency and trust are what will bring your sleep back to normal. Studies suggest the body clock can usually shift by about an hour a day.
