Understanding Sleep Hygiene

Sleep hygiene is the set of habits and behaviors that you practice before, during, and after sleep to promote healthy sleeping patterns. It’s important to develop a regular, consistent sleep schedule which can significantly impact your physical and mental health. From setting bedtimes to drinking stimulants in the evening, various practices can help or harm your sleep hygiene. Understanding the basics of sleep hygiene is essential for maintaining a healthy and consistent sleep schedule.

Sleep hygiene also contributes a lot to one’s cognitive health. Healthy sleep patterns can help to improve your memory, concentration, learning ability, and performance. Proper sleep hygiene ensures that your body can enter deep sleep, which is essential for forming memories and consolidating information. Evidence suggests poor sleep hygiene could be associated with cognitive decline and memory impairment. One’s sleep quality is directly related to cognitive performance, highlighting the importance of addressing sleep disturbances to protect mental health at a population level.

Common Mistakes in Sleep Hygiene

When it comes to sleep hygiene, many common mistakes people make can significantly impact their sleep quality. Different habits, behaviors, and environmental factors can all contribute to poor sleep hygiene.

One of the most common mistakes is having an irregular sleep schedule. According to a study, people with irregular sleep patterns were likelier to have metabolic disorders such as obesity, diabetes, and high cholesterol than those with regular sleep patterns.

Another common mistake is spending too much time in front of screens. The blue light from electronic devices can prevent melatonin production, a hormone that helps regulate your sleep-wake cycle. The light from screens can trick your brain into thinking it’s still daytime, disrupting your circadian rhythm and making it difficult to fall asleep.

Lastly, having an improper bedroom environment can also harm your sleep. For one, poor air quality in the bedroom can make it difficult to breathe and get comfortable. Excessive light in the bedroom can also disrupt sleep quality by preventing melatonin production. And, of course, noise pollution in the bedroom is another big issue that can disturb sleep, leading to an increase in your body’s production of adrenaline, a faster heart rate, and even the potential for an increased risk of diabetes, depression, and hyperactivity.

By identifying and addressing these common mistakes, you can improve your sleep hygiene and get a better night’s rest.

Mistake 1: Irregular Sleep Schedule

A consistent sleep schedule is one of the most important aspects of good sleep hygiene. The body’s circadian rhythm is essential for regulating sleep-wake cycles, and when it is disrupted, one can often experience difficulty sleeping. Some evidence suggests that an irregular sleep schedule can have other physical and mental health implications.

An irregular sleep schedule can throw off the body’s natural hormone production, leading to fatigue and difficulty concentrating. It can also lead to poor performance on cognitive tasks like memory formation and problem-solving. Additionally, chronically irregular sleep patterns can increase the risk for metabolic disorders such as diabetes, obesity, and high cholesterol.

To create a consistent sleep schedule, it’s best to go to bed and wake up at the same time every day. This will help your body become accustomed to a set sleep-wake pattern and establish healthy, regular sleeping habits. Setting alarms to remind yourself of bedtime can also help maintain consistency. You should also aim to get 8-9 hours of sleep every night, as this will help ensure you get the restful sleep needed for optimal cognitive performance.

Some people also find it helpful to establish a nighttime ritual. This can include reading, stretching, or listening to music before bedtime. These activities can help relax the body and prepare it for sleep. They can also structure your day, allowing you to adjust more quickly to a consistent sleep-wake pattern.

Mistake 2: Excessive Screen Time

Excessive screen time is one of the most common mistakes in sleep hygiene. The blue light that emits from electronic devices can interfere with melatonin production. Too much light exposure also makes it difficult for your brain to recognize when it’s time to sleep, disrupting the body’s natural circadian rhythm. Furthermore, spending too much time in front of screens can lead to overstimulation and make it difficult to wind down for bed. And, of course, it can distract from the other activities that help promote better sleep, such as reading or stretching.

Limiting your screen time in the evening is essential to protect your sleep. Reduce your nighttime device usage to avoid the potential for blue light exposure and overstimulation. If you can, try to turn off all devices at least an hour before bedtime. This will help signal your brain that it’s time to rest and allow you to enter a relaxed state that is conducive to falling asleep.

A digital detox may also be beneficial. Regular breaks from digital devices can help you become more aware of the time and adjust to a consistent sleep schedule. For example, you can turn off all devices a few hours before bedtime or commit to one day each week when you don’t use any digital devices. These activities can help reduce your reliance on screens and improve sleep quality.

Mistake 3: Poor Bedroom Environment

Having a conducive bedroom environment is essential for quality sleep. Poor air quality, excessive light, inconsistent temperature, and noise pollution can all disrupt your sleep-wake cycle and make it difficult to rest. Instead, you want a comfortable, quiet bedroom environment that encourages relaxation and induces sleep.

Start by assessing the air quality in your bedroom. Ensuring enough ventilation will prevent dust, allergens, and other pollutants from circulating. If you think the air quality in your bedroom needs to be improved, you can use air purifiers or invest in plants that absorb pollutants and release clean oxygen into the air.

Noise pollution is another important factor when creating a conducive sleeping environment. Noise can make relaxing and falling asleep difficult, leading to increased adrenaline production and potential long-term health risks. If you don’t have soundproof windows, you may want to invest in a white noise machine or earplugs to prevent outside noise from disrupting your sleep.

Temperature also plays a role in sleep quality. The optimal sleeping temperature is 60 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius). Too hot or too cold of a room can make it difficult to get comfortable and lead to tossing and turning throughout the night. You may want to invest in a good thermostat or air conditioner to help you maintain your bedroom’s optimal temperature.

Finally, light can also be an issue regarding sleep hygiene. While some people may find a night light helpful, excessive light can interfere with the body’s production of melatonin. Investing in blackout curtains or an eye mask can prevent excess light from entering your bedroom and help you get a better night’s sleep. Try to keep your bedroom as dark as possible.

Mistake 4: Unhealthy Sleep Habits

Unhealthy sleep habits can also significantly impact sleep quality. Consuming coffee close to bedtime is one of the most common unhealthy sleep habits. As a stimulant, caffeine can interfere with the body’s natural circadian rhythm. Caffeine takes six to eight hours to leave your system, so avoiding consuming coffee or other caffeinated beverages at least six hours before bedtime is best.

Alcohol can also make it difficult for your body to enter deep sleep, leading to fatigue and cognitive impairment the next day. So, it’s best to avoid drinking alcohol close to bedtime. Healthy, caffeine- and alcohol-free alternative drinks include chamomile tea, warm milk, or herbal teas. These drinks can help relax your body and prepare it for restful sleep.

Of course, eating a heavy meal close to bedtime can also negatively affect sleep quality due to indigestion and discomfort. Eating a light snack before bed is fine, but it’s best to avoid heavy or sugary foods that can disrupt your sleep. Instead, opt for light snacks like a handful of nuts or some yogurt.

Another unhealthy sleep habit is engaging in strenuous activities right before bedtime. Physical activity can make it more difficult to wind down and relax for sleep, so it’s best to avoid exercising or doing strenuous activities at least two hours before bedtime. You can engage in activities such as reading, stretching, or journaling instead to help you relax.

Some people also find that napping or sleeping throughout the day disrupts their natural sleep-wake cycle. Many people are tempted to take naps during the day or sleep in on the weekends. However, doing this can throw off your body’s sleep cycle and make it more difficult to fall asleep at night. Try to avoid naps or sleeping in during the day if possible.

Mistake 5: Lack of Relaxation Techniques

Relaxation techniques are essential for unwinding and preparing the body for sleep. Stress, worries, and racing thoughts can make relaxing and falling asleep at night difficult. Relaxation techniques can help relieve tension in your body and mind, allowing for a more restful sleep. By disengaging from anxious thoughts and relaxing, you can help your body enter a state of restfulness and sleep easier. Many different relaxation techniques can help you get a better night’s sleep.


One of the best relaxation techniques for sleep is meditation. Meditation helps reduce stress and clears your mind of anxious thoughts. You can focus on your breath or practice body scanning to do this. Listening to guided meditations before bed can also help calm the mind and ensure a restful night’s sleep.

Deep Breathing

A simple but effective relaxation technique is deep breathing. This helps relax the body and can slow down a racing mind. Focus on taking deep, calming breaths in and out. You can even count to four or five on each breath in and out. This will help reduce tension in the body and mind, allowing you to sleep easier.

Progressive Muscle Relaxation

Another relaxation technique is progressive muscle relaxation. This involves tensing and then releasing different muscles in the body, one by one. Start with your toes and work your way up to the top of your head. Spend a few seconds tensing each muscle and then release. This can help relax the body and prepare it for sleep.

Yoga and Stretching

Instead of strenuous activities, you can practice gentle stretching or yoga poses that help relax the body. This helps loosen tight muscles and ease tension in the body. It can also help clear your mind and promote relaxation. Try to practice gentle stretches or yoga poses at least an hour before bed, as this can help you wind down and prepare for sleep. But, of course, avoid any strenuous yoga moves that can get your heart rate up.

Developing Healthy Sleep Hygiene Habits

Developing and maintaining healthy sleep hygiene habits is essential for a good night’s rest. Depending on your individual needs and lifestyle, there are various steps you can take to ensure that you have good sleep hygiene. Aside from the tips mentioned above, here are other ways to help you develop healthy sleep habits:

Use your bedroom only for sleeping

When you enter your bedroom, you should only engage in activities promoting sleep. This means avoiding screens or any other distracting and stimulating activities that can interfere with your sleep.

Exercise regularly

During the day, engage in regular physical activity. This can help improve sleep quality by reducing stress and fatigue. By burning off excess energy during the day, you can prepare your body for restful sleep.

Schedule time for relaxation

Set aside some time at the end of the day to relax and unwind. This can help transition your body from an alert state to a calmer one conducive to sleep. If possible, try to avoid stimulating activities close to bedtime.

Avoid naps

Napping can interfere with your body’s natural sleep-wake cycle, making it more difficult to fall asleep at night. If you need to nap, limit it to one 20-minute power nap during the day and avoid napping close to bedtime.

Make necessary lifestyle changes

Making specific lifestyle changes can also help improve your sleep hygiene. Eating a balanced diet and avoiding drinks with caffeine and alcohol can help enhance sleep quality. Additionally, make sure to get enough sunlight during the day and avoid blue light exposure at night. These changes can help your body adjust to a consistent sleep-wake cycle and ensure you get the restful sleep needed for optimal cognitive performance.

If you still have trouble sleeping after making the necessary adjustments to your sleep hygiene, it may be time to seek professional help. Chronic insomnia and other persistent sleep issues can significantly impact your mental and physical health. Other sleep disorders, such as sleep apnea, restless leg syndrome, and periodic limb movement disorder, can also make it difficult to get a good night’s rest.

If you need professional help, ask your doctor for a referral to a sleep specialist. A specialist can assess your sleep habits and recommend lifestyle changes or treatments to help you get a better night’s sleep. This may include cognitive behavioral therapy, lifestyle modifications, or medications.

Some clinics also offer sleep studies to assess your sleep behavior. As you sleep, you’ll be monitored in a laboratory, and a specialist will analyze the results. This can help determine the underlying cause of your sleep issues and allow for more effective treatment.
