Is It Possible to Wake Up Without an Alarm?

Humans have a natural circadian rhythm that controls sleep cycles and wake times. With enough sleep, a consistent sleep schedule, and exposure to natural light, your body will help you wake up without an alarm clock.

Alarm Clocks Can Mess With Sleep Quality and Circadian Rhythms

If you have any morning schedule, whether school or work, you’ve probably incorporated an alarm clock to ensure you can be where you need to be on time. When you wake up to an alarm clock, your body can find it jarring, and you’ll often feel as though you haven’t gotten a good night’s sleep. The truth? It’s because you probably didn’t. Depending on the alarm clock can mean your sleep quality is lacking. Your body clock alarm, aka your circadian rhythm, controls your natural sleep cycle. It tells you when to feel tired (or when to hit the snooze button) and when to feel alert. With enough sleep and a consistent sleep-wake schedule, your circadian rhythm will help you feel alert during the daytime and sleepy in the evening. But, if you’re sleep deprived, you might have trouble waking up to your alarm, and in the worst of times, you may even sleep right through it!

Disrupted Sleep Cycles Make Waking Up Harder

Alarm clocks can be aggravating and disruptive, and many of us prefer to wake naturally rather than be jolted into consciousness. Natural light is our body’s most excellent trigger for waking up. If your body can’t jumpstart to the morning light and needs an alarm clock, it might be a good indicator that your body isn’t getting the sleep it needs. The impact of alarm clocks on sleep cycles. Our sleep is made up of cycles, each lasting about 90 minutes. We move through different stages during each sleep cycle, including:

Deep sleep
REM sleep

If an alarm clock wakes you from deep sleep, you will likely feel groggy and disoriented. This grogginess, sleep inertia, occurs when you interrupt your body’s crucial restorative process, making it more challenging to get your day going.

The Snooze Button Is Not Your Friend

Many of us hit the snooze button for extra minutes of sleep. These brief interruptions in sleep can make you feel more tired. When you go back to sleep for just a few minutes, your body starts a new sleep cycle that gets interrupted when the alarm goes off again, leading to even more grogginess when you finally get up.

Sleep Anxiety Can Make Waking Up to an Alarm More Stressful

Regular use of alarm clocks can also lead to a kind of sleep anxiety for some people. You might wake frequently at night to check the time because you’re worried about oversleeping. This can disrupt your sleep even further and reduce the overall quality of your rest.

The Stress of Waking Up to an Alarm Can Ruin Your Mornings

Starting your day with stress. A loud alarm can jolt you awake suddenly, so your day starts with a surge of stress. This abrupt wake-up call can trigger a rush of adrenaline and cortisol — stress hormone — making your mornings feel hectic and unpleasant.

Light Can Help Reset Your Circadian Rhythm

In an ideal world, we wouldn’t need alarm clocks; we would simply go to bed when we felt tired and sleep until we were ready to wake up. The ubiquity of artificial light after dusk means that relying on when we feel sleepy to dictate our bedtimes isn’t very helpful. Our natural sleep rhythm has shifted later, yet most of us must wake up at a prescribed time to go to work or school, meaning our sleep is cut short. It also means that we often wake up when our bodies think it is still night-time, which increases feelings of “sleep inertia” – the grogginess you experience immediately upon waking. US researchers showed that when people were sent on a camping trip and denied access to their electronic gadgets, their circadian rhythms shifted about two hours earlier, meaning they felt sleepier and got more sleep.

Everyone Is Different: Chronotypes Affect Natural Wake Times

So, is it better to get up early or late? That depends on your chronotype – your natural sleep-timing preference – which is hardwired in your genes. “It is not a choice and it is very difficult to change,” says Matthew Walker, a professor of neuroscience at the University of California, Berkeley, and the author of Why We Sleep. Some people are larks and predisposed to wake up early. Others are late types who naturally sleep in; most of us lie somewhere in between. Even night owls can become a little more lark-like if they reduce their exposure to light at night and seek out bright light from when they wake up, pushing the master clock earlier. These innate sleep preferences also vary with age. Teenagers’ sleep timing typically shifts about two hours later, while as we get older, we become progressively more lark-like.

Consistency Is Key for Natural Wake Times

Consistency in the timing of your sleep is more important than when you prefer to get up. If you go to bed and wake up later at weekends, you are effectively giving yourself jet lag – and when your alarm clock wakes you at 7 am on Monday, your body will still think it’s night-time. “The most important advice I can give people who are struggling with sleep or want to get good-quality sleep is to keep it regular,” says Walker.

Train Your Body to Naturally Wake Up at a Certain Time

Can you train yourself to get up at a particular time without an alarm clock? Yes, provided you sleep at about the same time every night and wake at the same time each morning, says Lisa Artis, an adviser for the Sleep Council. “Your internal body clock will strengthen, and you will start to wake naturally at a time that suits you. Even so, if not setting an alarm will make you anxious about sleeping in and missing a train or an important meeting, you should set the alarm,” she adds. “Otherwise, you will spend most of your time in bed worrying you won’t get enough sleep.”

How to Wake Up Without an Alarm & Reset Your Natural Sleep Cycle

1. Harness the Power of Morning Light

Regular daylight exposure in the morning is one of the most potent ways to regulate your circadian rhythm. Morning sunlight helps the body coordinate its internal clock, influencing when you feel alert or sleepy. Most experts recommend at least 30 minutes of daylight exposure every morning to help establish a sleep-wake cycle conducive to waking up without an alarm. Natural light exposure is optimal, but some bright lights can also benefit. Waking up with the sunrise can ensure morning light exposure and eliminate the need for an alarm. Light therapy lamps with at least 10,000 lux of light are recommended when natural light exposure is impossible, especially in dark winters.

2. Simulate Dawn

A dawn simulator or wake-up light can facilitate waking up without an alarm. These devices gradually increase bedroom illumination for 15 to 45 minutes before a set wake-up time. Designed to mimic the sunrise, dawn simulators slowly nudge a sleeper toward awakening. One study found that dawn simulators improved alertness and cognitive function after waking up.

3. Keep a Consistent Schedule

Studies have found that self-awakening is more common in people who keep a consistent sleep schedule, so try to stick to a set bedtime and wake-up time. When determining a schedule, budget enough time to get the recommended amount of sleep. Keep the same sleep schedule every day, including weekends. Big swings in sleep timing can throw off sleep patterns. Insufficient sleep can also cause debt to build up, making it hard to wake up early without an alarm. “Your alarm can wake you up during the middle of a sleep phase, which can cause sleep inertia, or the groggy feeling from abruptly interrupted sleep.” Dr. Lulu Guo, Sleep Physician

4. Dim the Lights Before Bed

Too much artificial light at night can delay circadian rhythms and make waking up early without an alarm more difficult. About two hours before bedtime, dim the lights and avoid bright light from TVs, mobile phones, and other screens. Blue light exposure in the evening can be incredibly disruptive to sleep by suppressing Melatonin release, a natural hormone regulating our circadian rhythm. Blue light is usually from viewing screens such as:

TVs
Phones
Computer monitors

If these devices are needed in the evening, wearing blue light-blocking glasses can help.

5. Avoid Sleep Disruptors

Avoid things that can interfere with normal sleep to maintain a regular sleep schedule.

Caffeine: Because this stimulant stays in the body for several hours, it should be avoided in the late afternoon and evening.
Alcohol: Alcohol can interfere with normal sleep stages, so limit or eliminate alcohol intake at night.
Nicotine: Nicotine is a stimulant, which makes tobacco consumption before bed detrimental to sleep.
Heavy meals: Eating a big dinner too late at night can lead to an upset stomach that throws off normal sleep. This can also trigger insulin release late at night, keeping you up for longer or resulting in more disrupted sleep.

6. Exercise early in the morning

If you want to go to bed earlier to wake up at a good time, try exercising earlier. Regular exercise is excellent, but if you hit up your weights session at 5–8 pm (primarily if you use pre-workout or other caffeine supplements), you might struggle to fall asleep or even stay asleep during the night time. Incorporate exercise into your morning routine. It’ll keep you alert for when you need to be alert and help you fall asleep faster in the evening.

7. Avoid eating too close to bedtime

Eating before bedtime can cause disrupted sleep. If you want to wake up without an alarm clock, it’s highly recommended that you have your last meal 2-3 hours before going to sleep. Opt for a light snack if you need to eat before bedtime. Why is this the case? It’s because your body needs time to digest your food. If you go to sleep while your body is still digesting, it might cause an upset stomach, acid reflux, or even indigestion. That said, don’t ditch a meal just to follow this rule! It’s not hard and fast – if you simply had a busy schedule that day and you’re eating closer to bedtime than you’d like, it’s OK to do it occasionally. Try easy-to-digest foods like:

Toast
Rice
Nuts
Fish

8. Try some wake-up lights

Like alarm clocks, wake-up lights help you wake up naturally by simulating a sunrise within 30 minutes and two hours of your desired wake-up time. This way, you won’t have to hit snooze because your biological clock will tell you it’s morning. Wake-up lights can get you started to better your circadian rhythms, but they’re not something to be depended on. First, You’ll want to be sure you’re getting a quality seven to nine hours of sleep and that you have no pre-existing sleep disorders causing a distorted sleeping schedule. Once the wake-up lights have done their trick, try implementing a few or all of our other tips.

9. Support sleep with your diet

What you eat—and when you eat—can affect your sleep. Avoid heavy meals, caffeine, and alcohol close to bedtime. If you feel hungry, choose a light, healthy snack full of nutrients.

10. Consider your other lifestyle factors

Sometimes, it’s not about the hours you spend lying in bed but the quality of those hours. For good quality sleep, you will want to address the other things you have going on in your life before you can expect to get quality hours of sleep. Consider any health conditions, injuries, or bedroom environment issues that may be contributing to you feeling groggy. If your bedtime routine is off because of your work schedule, try a bedtime routine to get yourself all relaxed before you try falling asleep. When all else fails, it’s time to consult a physician. Sleep is imperative to your well-being and as essential to your overall health as nutrition and water. If your sleep quality is lacking and none of these tips seems to help, contact your family doctor.

How Long Does It Take to Adjust to Waking Up Naturally?

Waking up naturally is like building a new habit. The time it takes to adjust to waking up naturally can vary from person to person. It may take you anywhere between 30 to 60 days to get accustomed to the habit of waking up early. Once you get used to your new sleep schedule, you won’t need an alarm to wake you up.

Start Gradually: Work Your Way to Waking Up Early

Setting realistic expectations and gradually easing into waking up early can help your body adjust to the new schedule. Don’t start with an unnatural hour. For example, if you are used to waking up at 7 a.m., start by setting the alarm for 6:45 a.m. Once your body adjusts to this change and you find it easier to fall asleep early, you can push it further by another 15 minutes. Going step by step will help your body better adapt to the change. When you wake up 15 minutes earlier than usual, you won’t resent the idea and give it up altogether, feeling sleep-deprived.

Kick the Snooze Button to the Curb

Keeping the alarm clock away from the bed decreases your chances of hitting the snooze button. Instead of keeping the clock on your bedside table, you can keep it on a shelf or a table on the other side of the room. When the alarm rings, you’ll have to walk up to it to turn it off. Taking those few steps to your alarm may help you shake yourself out of slumber.

Get Out of the Bedroom As Soon As You Wake Up

Your brain is conditioned to feel sleepy in the bedroom. Stepping out of the bedroom as soon as you wake up discourages you from returning to sleep. While trying to become early risers, many night owls give in to the temptation of going back to bed when they spend time in the bedroom.

Motivate Yourself to Rise and Shine

Having the motivation to get up will help you wake up early. For example, you may want to wake up early to go to the gym or spend time gardening. Whatever the motivation, try to keep something associated with it right before you. For example, you may keep your gym clothes or gardening gloves where you can see them as soon as you get out of bed. Make plans for when you wake up.

Reward Yourself for Waking Up Early

While training yourself to wake up early, you can incentivize the system. You can treat yourself to your favorite flavor of coffee or spend extra time in the shower. Do something that you don’t usually do to make yourself feel remarkable about your achievement of waking up early. Rewarding yourself helps you continue the practice diligently.

Follow Proper Sleep Hygiene

Develop a bedtime routine that tells your body it’s time to sleep. For example, take a hot shower, read your favorite book, or reminisce about the positives in your day. All of these help you unwind and prepare your body to sleep. Taking a warm water shower physiologically prepares your body for sleep. The warm water raises your body temperature then drops immediately as you step out of the shower. When you sleep, your body experiences a drop in temperature, so a warm bath facilitates this sleep process.

Be Kind to Yourself During the Adjustment Period

If you feel under the weather or exhausted, be easy on yourself and don’t force yourself to wake up too early. This flexibility will prevent you from resenting the idea of waking up early.

Eliminate Excuses for Sleeping In

When you train yourself to wake up in the morning, you may feel like sleeping on a rainy or cold day. Try to avoid giving in to such excuses because once you give in, it’ll be challenging to break out of the habit, and you’ll have to retrain yourself all over again.
