- Morning Alarms to Keep on Schedule: Alarm clocks can help normalize sleep schedules, ensure punctuality, and provide peace of mind about waking up on time. However, there are potential downsides to alarm clocks, including sleep anxiety, stress from sudden wake-ups, and disruption of natural circadian rhythms.
- Alarm Clocks Can’t Make Up for Poor Sleep: Maintaining good sleep hygiene, going to bed with enough time for sufficient sleep, keeping regular sleep hours, and avoiding the snooze button can help reduce reliance on alarm clocks. Listening to your body’s sleep needs and addressing any underlying sleep issues is essential for waking up refreshed and on time.
- How You Can Be Woken Up: Don’t like the beeping of a standard alarm clock? Some smart alarm options exist, such as those that use light or vibrations to wake you gently, and they can be considered as alternatives to traditional alarm clocks.
Alarm clocks are a common fixture in most bedrooms, but do they actually help us get better rest? Let’s take a look at the history of alarm clocks and see what the experts think about their role in achieving healthy sleep.
Origins of Alarm Clocks
People have been using alarms of sorts to wake up well before clocks were even a thing. The morning sun was the original cue to rise and shine, and roosters have likely been crowing sleepers awake for eons.
Plato is said to have woken up early with a clever device that used draining water to signal a whistle as the contraption filled, supposedly spurring the development of later mechanical time-keepers. Church bells have awoken communities for morning service for centuries, and by the 1300s, we can find descriptions of chiming clock towers in Europe designed to inform residents of the time.
Later, booming industrial factories in the 18th century relied on an on-time workforce, and would sound morning whistles to rouse their workers living nearby. Some cities and companies even employed a “knocker-up”, designated people that would go door to door delivering wake up calls.
Although existing as early as the 1500s, it wasn’t until the 1870s that alarm clocks started to become a common thing in private homes with the advent of the mechanical wind-up version. Over time, this fixture cemented it’s position in the bedroom, incorporating additional features like radio receivers, cuckoos, snooze buttons and more. Modern alarm clocks continue to evolve, with everything from light-based alarms to clocks that run across the room, and even phone apps.
With jobs, school and other responsibilities, waking up by a set time remains a must for the majority of us. So, naturally, many people depend on alarm clocks to start the day. But, are they really doing us a favor, or is this reliance on alarm clocks detrimental?
How Morning Alarms Help Us
Alarm clocks have been in use for centuries because they solve a real problem—ensuring we wake up on time. Their utility is undeniable, and many of us would probably have a hard time making it to work every day without one.
Mark Muehlbach, Ph.D., F.AASM, R.PSGT, clinical director at the Clayton Sleep Institute in St. Louis, provides a little background on why waking up in the morning can be so difficult:
Here’s a an overview of the ways alarm clocks benefit us:
Staying on Society’s Time
Without alarms, many of us would oversleep and wind up late for work. As great as sleeping in sounds, being on time is a (harsh) reality we often must abide. In order for business and schools to run smoothly, agreeing on a set time to be there can be essential, whether you’d like more sleep or not.
Plus, too much oversleeping can have its drawbacks when it comes to your health.
Normalizing Sleep Schedules
Alarm clocks can also be helpful for keeping sleep schedules regular. Waking up around the same time each day is beneficial for our internal biological clocks. Using an alarm clock can help keep your schedule consistent and normalize your sleep patterns.
Peace of Mind
Richard Shane, PhD, psychotherapist and Founder of Sleep Easily, suggests that alarms can also provide peace of mind, adding:
Potential Downsides of Alarm Clocks
However, alarm clocks aren’t always helpful; in fact, sometimes they can be counterproductive to overall health and even for getting good sleep.
Sleep anxiety, or worrying about not falling asleep or what can happen while you’re asleep, can paradoxically contribute to insomnia. And, alarm clocks are right there helping, counting down the precious minutes of sleep left until wake up time. Most sleep experts suggest covering clock faces or turning them away from the bed so you’re not tempted to watch the minutes tick by.
Levels of the stress hormone cortisol naturally rise shortly after waking for most people. Although there’s no studies showing alarms further increase cortisol, being startled awake by a loud alarm first thing in the morning certainly doesn’t make things more relaxing.
Researchers are also looking into correlations between heart attacks and alarm clocks, due to their adrenaline-spiking jolt which can trigger the flight-or-fight response and accelerate heart rate and blood pressure.
Social jetlag refers to the sleep deprivation many people experience as they try to eek by on less sleep in order to keep up with social demands. Oneshowed that two-thirds of adults sleep over an hour more on weekends as opposed to weekdays, and that although wakeup times are staying the same, we are going to bed later. Researchers argue this is messing with our internal biological clocks, affecting sleep and significantly increasing risk of weight gain and obesity as well.
Some alarm clocks have brightly-lit faces, and while good for seeing the time, researchers have found thatcan affect sleep.
How to Wake Up Refreshed and On-Time
So, is there a better way to wake up? The ability to rise the morning after a full night’s rest, without needing an alarm, is something plenty of people would prefer over blaring beeps.
However, most of can’t just toss the alarm in the trash and tell the boss we’ll be in whenever we get up. Following good sleep habits and making sure you’re actually getting enough sleep are good ways to begin repairing your internal clock, though.
1. Follow Good Sleep Hygiene
Sleep hygiene refers to habits shown to help encourage better rest. These include things like:
- Eating a balanced diet with plenty of nutrients, and drinking plenty of plain water during the day.
- Avoiding stimulants in the evening like caffeine.
- Getting regular exercise and some time in the sun (for Vitamin D).
- Sleeping in a cooler bedroom with a comfortable mattress and bedding.
- Minimizing use of electronics like smartphones and TVs before bed, and keeping bedrooms as dark as possible during rest.
2. Go to Bed with Plenty of Time
If you find it impossible to wake up in the morning without an alarm or feel groggy after waking fairly often, take a look at how much sleep you’re actually getting.
Dr. Lynn Johnson, psychologist and author of The Healing Power of Sleep, says we need seven and a half to eight hours of sleep a night, adding:
And, when sleep experts say you should get seven to eight hours of sleep, they mean actual sleep, not just time spent in bed. If you tend to take a while to settle in and relax, factor that into your allotted bed time.
For example, if it usually takes you around 30 minutes to get in the zone and you need 7.5 hours to feel your best, aim to be in bed at least eight hours before you need to wake up. Turning in with time to spare can also reduce sleep anxiety, so you aren’t counting down the time on the alarm and hoping to fall asleep quickly.
If you find it takes a very long to time to fall asleep or you wake often through the night, try instituting earlier cut-off times for things like caffeine and electronics, or incorporate stress relief habits like deep breathing or stretching before bed.
3. Keep Regular Hours, Avoid Snooze
If you’re one of the many that can’t wake up on time without an alarm, it might surprise you to know that we all actually have an internal alarm of sorts. Researchers have identified biological processes that signal to the body when it’s time to get drowsy and when it’s time to wake up.
The best way to support this natural rhythm is keeping a regular bedtime and waketime. People on regular schedules often find they wake up before their alarm even goes off, for example.
But, there are several things that can throw our internal clocks off, including aging, shifting schedules, and travel. So, alarm clocks aren’t all bad, and for a lot of people, they are very necessary to maintain a regular schedule.
But, try not to hit snooze, says Dr. Muehlbach:
Other sleep researchers concur, suggesting that hitting the snooze button actually sets you up for groggier mornings, and can even make you feel like you had a worse night’s sleep overall. Use your alarm clock to stick to a regular schedule, as this will be most helpful for your body’s internal clock.
4. Try a Smarter Alarm
A few companies and app developers offer takes on gentler versions of morning wakeup calls. From rousing you with bright light or vibrations to aiming for a more ideal wakeup time in your sleep cycle, you might find one of these solutions help you wake up on time without the headache inducing bleating of a traditional clock.Several free or inexpensive apps can be found in both Android and iOS stores, and companies like Philips and Lumie make popular wake-up alarm clocks.
If you do require an alarm clock, Dr. Richard Shane offers the following suggestions for minimizing sleep disturbances:
One wearable smart alarm, the Sleep Shepherd Blue, aims to help people sleep better by monitoring biofeedback and brain waves, inducing relaxation with binaural beats and waking you up gently at the ideal stage. Engineer and Sleep Shepherd creator Michael Larson, PhD, explains the workings behind the smart alarm concept:
5. Listen to Your Body
If you wake up every morning groggy and tired, it might be time to readjust your sleep schedule, perhaps going to bed 15 or 30 minutes earlier until you feel more refreshed.
Changes in age, stress, health and many other things influence the amount of sleep we need. Even an old mattress can contribute to less restful sleep according to so be aware of your sleep environment too.
If you have the basics of healthy sleep down and still feel tired, there could be other factors at play. Dr. Muehlbach explains:
If difficulty falling asleep or staying asleep impacts your ability to feel rested during the day and incorporating healthy sleep habits isn’t helping, bring it up with your doctor. Things like sleep apnea, restless leg syndrome, and insomnia can have significant effects on how you feel during the day, and often go undiagnosed.
