Sleep hygiene is a set of behavioural and environmental practices developed in the 1970s to help people with insomnia and other conditions like depression. It includes setting a strict sleep schedule, following a bedtime routine, forming healthy habits, and optimising your bedroom for sleep. While sleep hygiene can be an important part of a public health strategy, it is not always effective in treating insomnia. This has raised questions about the ineffectiveness of sleep hygiene as a treatment in clinical sleep medicine. Sleep is closely tied to mental health, and insomnia can worsen mental health problems. Therefore, it is essential to address the root causes of insomnia, such as ongoing pain, depression, or anxiety, rather than solely focusing on sleep hygiene practices.

What You'll Learn
Sleep hygiene is a behavioural and environmental practice
Sleep hygiene is a set of behavioural and environmental practices developed in the late 1970s to help people with mild to moderate insomnia. It involves assessing sleep habits and offering recommendations to improve sleep quality and quantity. Sleep hygiene practices include establishing a regular sleep schedule, being mindful of napping, limiting physical and mental exertion before bed, reducing worry, minimising light exposure in the evening, avoiding stimulants like caffeine and alcohol, and creating a peaceful, comfortable, and dark sleep environment.
The effectiveness of sleep hygiene as a treatment for insomnia and other sleep disorders has been questioned, with research showing inconsistent results. While it provides a framework for improving sleep habits, it may not address underlying causes of sleep problems, such as pain, depression, or anxiety. For example, individuals with depression may struggle with good sleep hygiene practices, as they are more likely to take naps during the day, consume alcohol or caffeine, and have disrupted sleep environments.
However, sleep hygiene can be a powerful tool when combined with other treatments. Cognitive behavioural therapy for insomnia (CBT-I) includes sleep hygiene practices and helps individuals identify and replace harmful behaviours that interfere with sleep. Stimulus control therapy retrains the brain to associate bed with sleep rather than wakefulness, encouraging a consistent sleep schedule and avoiding long naps late in the day. Relaxation techniques, such as meditation and muscle relaxation, can also be employed to soothe the body and mind, making it easier to fall asleep.
Overall, sleep hygiene is a low-cost, low-risk practice that can benefit anyone seeking to improve their sleep. It involves creating a sleep-promoting environment and set of routines, including a fixed wake-up time, a regular sleep schedule, and a bedtime routine. By prioritising sleep and making gradual adjustments, individuals can improve their sleep hygiene and, consequently, their sleep quality and overall health.

Sleep hygiene doesn't address the root causes of insomnia
Sleep hygiene is a set of behaviours that promote good sleep. It includes keeping a consistent bedtime and wake time, maintaining a cool and dark bedroom, winding down at bedtime, and helping your body relax. While these behaviours can be beneficial for average sleepers, they may not be sufficient for individuals with insomnia.
Annie Miller, a behavioural sleep medicine therapist at DC Metro Sleep and Psychotherapy, states that "sleep hygiene gives you a framework to change some habits, but it may not focus on these core things." Miller and other experts often use cognitive behavioural therapy (CBT-I) as a standard treatment for chronic insomnia. CBT-I includes sleep hygiene practices but also helps individuals identify and replace harmful behaviours that interfere with sleep quality.
In addition to CBT-I, there are other treatments for insomnia that go beyond sleep hygiene. Stimulus control therapy, for example, retrains the brain to associate going to bed with falling asleep rather than wakefulness. This involves setting a regular schedule for waking up and going to bed only when feeling sleepy. Relaxation techniques such as meditation and muscle relaxation can also help soothe the body and mind. Biofeedback is another technique that involves tracking heart rate, muscle tension, and other functions that impact sleep, allowing individuals to learn to control and relax these functions for better sleep.
While sleep hygiene can be a good starting point for improving sleep, it may not address the underlying causes of insomnia. It is important to explore other treatment options if sleep hygiene alone is not effective.

Light therapy as a treatment for insomnia and other health issues
Sleep hygiene alone may not be enough to address insomnia and other health issues. It does not address the root causes of insomnia, such as ongoing pain, depression, or anxiety. Light therapy, on the other hand, is a type of treatment for insomnia and certain sleep disorders that aims to reset your body clock. It involves sitting in front of a light therapy box, which emits bright light similar to natural sunlight. This light tells your body to stop producing melatonin, a hormone that aids sleep. The timing of light exposure is critical, and it can be used in the morning or evening depending on whether you have trouble waking up or tend to wake up too early.
Light therapy is one of the primary treatments for circadian rhythm sleep disorders, which can develop naturally or be brought on by working night shifts or travelling across time zones (jet lag). It can also be helpful for some types of depression. The treatment is generally safe, but individuals with bipolar disorder, skin or eye conditions, or sensitive eyes should consult a doctor before undergoing light therapy.
Light therapy is often used in conjunction with other treatments, such as cognitive behavioural therapy (CBT-I) for insomnia, which includes sleep hygiene as well as identifying and replacing harmful behaviours that interfere with sleep. Stimulus control therapy is another treatment for insomnia that involves retraining your mind to associate going to bed with sleep rather than wakefulness. This method includes setting a regular schedule for waking up, only going to bed when sleepy, and avoiding long naps late in the day. Relaxation techniques such as meditation and muscle relaxation can also help soothe the body and mind.

Sleep hygiene recommendations for college students
Sleep is a pillar of health that is often overlooked. College students often forego sleep to study or socialise, leading to sleep deprivation, insomnia, and irregular sleep patterns. 60% of college students suffer from poor sleep quality, and nearly 8% struggle with insomnia. This can compromise students' ability to understand and retain information, even affecting their grades.
- Limit caffeine, nicotine, alcohol, and stimulant drugs: These substances can disrupt your sleep. Avoid caffeine and stimulant drugs close to bedtime, and if possible, try to avoid alcohol.
- Avoid screens before bed: The blue light emitted by electronic devices can disrupt your sleep. Avoid phones, laptops, tablets, and desktops at least 30 minutes to an hour before bedtime.
- Establish a sleep schedule: Try to go to bed and wake up at the same time every day. This will help set your body's internal clock and improve your sleep quality.
- Create a relaxing bedtime routine: Engage in activities that help you relax before bed, such as taking a warm shower, drawing, journaling, or listening to quiet music.
- Make your bedroom sleep-friendly: Create a dark, quiet, comfortable, and cool sleeping environment. Consider using blackout curtains, a fan, and clean bedding.
- Exercise regularly: Daily physical exercise can help improve your sleep, but avoid intense exercise within two hours of bedtime.
- Manage stress: Write down any worries or frustrations in a notebook before bed, and then put the notebook away. This can help you relax and clear your mind for sleep.
- Seek help if needed: If you continue to have difficulty sleeping, consider speaking to a healthcare professional or a sleep therapist. They can help you identify any underlying causes of your sleeplessness and recommend appropriate treatments or therapies.

Sleep hygiene and its impact on mental health
Sleep hygiene refers to the sleep environment and daily routines that promote consistent, uninterrupted sleep. It includes setting a strict sleep schedule, following a bedtime routine, forming healthy habits, and optimising your bedroom for sleep. Sleep hygiene alone may not cure sleep problems, but it can be an essential part of improving sleep quality and overall health.
The impact of sleep hygiene on mental health has been the subject of several studies. Research has found a significant association between poor sleep hygiene practices and sleep problems, daytime sleepiness, and depression. Poor sleep hygiene can negatively impact both sleep quantity and quality, and treating sleep issues can improve mental health symptoms. For example, individuals with depression may be more likely to take naps during the day, consume alcohol or caffeine before bed, and spend more time in disruptive sleeping environments, all of which can contribute to poor sleep hygiene.
College students and shift workers are particularly at risk of poor sleep hygiene due to irregular schedules and environments that can disrupt their sleep-wake cycles. In addition, long and irregular work hours can force individuals to sleep during the day, disrupting their natural circadian rhythm and reducing the physiological benefits of sleep. This can result in a constant state of survival, releasing cortisol and adrenaline, which interfere with sleep. Therefore, addressing these behavioural and environmental factors through sleep hygiene practices can potentially improve sleep quality and positively impact mental health.
While sleep hygiene can be a useful tool for improving sleep, it may not address the root causes of insomnia or other sleep disorders. For example, ongoing pain, depression, or anxiety can contribute to insomnia, and sleep hygiene recommendations may not directly target these underlying issues. In such cases, additional treatments or therapies may be necessary to address the specific causes of insomnia and improve mental health outcomes. Overall, sleep hygiene can be a beneficial component of a comprehensive approach to improving sleep and mental health, but it should be combined with other strategies to address individual needs and circumstances.
