What is Sleep Hygiene and Why is It Important?

There is an old Irish proverb that says:

“A good laugh and a long sleep are the best cures in the doctor’s book.” [1]

It turns out that your grandmother and great-grandmother were right. Decades of research have confirmed their wise advice: the duration, as well as the quality of sleep, are foundational to human health, productivity, and happiness.

The path to good sleep, especially now, can be long and winding. After all, we’re constantly bombarded by the pressures of work, family, and global events. We’re also so busy that we sadly put our sleep needs on the back burner.

Unfortunately, many of us have been conditioned over the years to minimize the value of healthy sleep habits. We know now from definitive and well-executed research over time that sleep is not an optional activity. [2]

So, what helps us along that path to ha good nigh-quality’s sleep that rejuvenates our mind, body, and spirit?

The answer lies in optimal sleep hygiene.

What is Sleep Hygiene?

Think of sleep hygiene as your bedtime routine’s best friend. It’s all about creating healthy habits that make it easier to fall asleep and stay asleep.

This includes things like:

• Making your bedroom a sleep sanctuary: Think cozy, dark, and quiet. [3]
• Unwinding before bed: A warm bath, reading, or light stretching can do wonders.
• Sticking to a consistent sleep schedule: Go to bed and wake up around the same time each day, even on weekends.

All of these steps work together to give you optimal sleep hygiene. [4]

The ideal sleep hygiene strategy is different for everyone. Many factors come into play, including the following:

• Do you travel?
• Does your job require shift work?
• Do you have a medical condition or take medication that interferes with sleep?

Also, we’re all unique, with different backgrounds, cultures, and genetic histories. Thus, it takes time to explore and establish your own sleep hygiene design.

Sleep hygiene refers to the practices and habits that help promote better sleep, duration, and consistency. Good sleep hygiene is essential for overall health and well-being, as it can improve cognitive function, mood, and physical health.

On the flip side, poor sleep hygiene can lead to common sleep disorders, daytime fatigue, and other health problems. By understanding the importance of sleep hygiene, individuals can take steps to establish healthy sleep habits and reduce the potential risk of developing sleep problems.

Whether it’s creating a calming bedtime routine or optimizing your sleep environment, these practices can make a significant difference in achieving healthy sleep.

How to Improve Your Sleep Hygiene

Good sleep hygiene looks different for everyone, but the fundamentals don't change much. Your environment, your pre-bed habits, and your daily schedule all play a role in whether you're actually getting quality rest or just logging hours in bed.

Finding What Works for You

The beauty of an individualized sleep hygiene strategy is that you create something that works best for you. Thus, if you travel, your sleep recipe and special toolbox can travel with you. Sure, you won’t be able to sleep in your own cozy bed while staying at a hotel.

But still, you can certainly pack your comfy slippers and lower the room temperature. Every little bit helps when trying to maintain your bedtime ritual! [11]

For persistent sleep issues, consulting with sleep medicine specialists can be crucial. They can provide expert help and proper diagnosis, which can significantly enhance treatment outcomes for conditions like obstructive sleep apnea and insomnia.

Whether at home or on the road, many people can relate to the stress that’s created during the holidays or family gatherings. Even though we love our families, the tensions created can be similar to those of many high-stress professions. Why should you practice good sleep hygiene? By creating good sleep hygiene, it can help people cope with these stressors.

Admittedly, it can be difficult to find that “sweet spot” of the perfect sleep hygiene strategy. When it comes to caffeine intake (which includes other substances in addition to coffee), empirical research has reported a variety of findings.

The discrepancy might be due to the concept of half-life. Half-life can be described as the amount of time it takes for the body to metabolize approximately half of the drug it has consumed. In the case of caffeine, half-life is used as an approximation of when effectiveness begins to decrease. [12] [13]

How long caffeine stays in the body depends on the individual, their tolerance level, genetic makeup, total daily caffeine intake, and individual body metabolism. For some people, caffeine has no effect at all, meaning no sleep problems. [14] [15]

Did You Know: Nicotine, much like caffeine, acts as a stimulant that revs up your system, making it harder to wind down and fall asleep. That’s why smoking is often linked to a variety of sleep problems, from trouble falling asleep to waking up throughout the night.

But, it may affect you. If it does, learn more about how caffeine can affect your sleep.

The below checklist can help you find new ways to strengthen your sleep and bedtime rituals. Applying minor changes or adjustments can improve the quality of your sleep, resulting in more energy and improved mood. Give one or two a try, but be patient; keep in mind that it will take a few days (or weeks) to see changes.

Here’s a checklist to help you optimize your sleep:

Signs You Might Have Poor Sleep Hygiene Practices

Think of poor sleep hygiene like a messy room – it makes it hard to relax and get comfortable. Just like a messy room, weak sleep habits can make it tough to fall asleep and stay asleep.

Here are some common signs:

• Frequent Sleep Disturbances: Do you often wake up in the middle of the night and have trouble falling back asleep? Or do you toss and turn a lot throughout the night? These are signs that your sleep might be disrupted.
• Daytime Sleepiness: Feeling tired and sluggish during the day, even after a full night’s sleep? This could be a sign that your sleep isn’t as restful as it should be.
• Difficulty Falling Asleep: Do you find yourself lying in bed for hours, unable to drift off? This is a common symptom of poor sleep hygiene.
• Lack of Sleep Quality and Quantity: This means you’re not getting enough sleep, and the sleep you do get isn’t deep and restorative. You might wake up feeling unrefreshed, even after a full night.

Sleep Tip: Consider using a sleep tracker like Sleepme to gain a deeper understanding of your sleep

Final Thoughts

There are many benefits of good sleep hygiene, including preventing and developing sleep disorders and other related concerns. Sleep hygiene is essential for everyone, from early childhood to adulthood.

Scientific research continues to untangle the magic and mystery of this critical part of human self-care and development. One of the conclusions is that various sleep hygiene strategies work differently depending on genetics, personality, body metabolism, and a host of other factors. If you are still having trouble falling asleep, it’s recommended you speak with your doctor.

At sleepme, we encourage the exploration of your ultimate sleep hygiene design.

As Dr. William Dement, founder of the Sleep Research Center at Stanford University, once said, “You’re not healthy unless your sleep is healthy.” [16] In addition to his groundbreaking research, we wouldn’t be surprised if he also listened to his grandmother.
