---

Introduction

Healthy sleep habits are crucial for improving mental health and overall well-being. By practicing good sleep habits, people can experience improved mood, better cognitive function, and a reduced risk of mental health issues such as racing thoughts and nightmares.

This guide introduces the concept of sleep hygiene and offers practical suggestions for improving your sleep environment, establishing effective bedtime routines, and developing positive daily habits.
It also includes a sleep hygiene checklist to assist you in making small yet impactful changes that can lead to better sleep and improved mental health.

What is Sleep Hygiene?

Sleep hygiene refers to the habits, behaviors, and environmental factors that can be adjusted to promote a good night’s sleep. ^[1]. It encompasses a variety of practices and habits necessary for optimal nighttime sleep quality and full daytime alertness. ^[4] .

The term “sleep hygiene” builds on the understanding of several clinical terms related to sleep and biological health. ^[4]

Definition and Key Concepts

The idea behind sleep hygiene is simple. It suggests certain habits and settings to help you sleep well. They developed it first to help people fight light to middle-level sleep problems. But everyone can benefit from its rules.
Doctors suggest adults sleep straight for seven to nine hours each night, although this could differ for different people.

Knowing how to make a bedroom suitable for great sleep is what good sleep cleanliness is about. It has to do with things like what you eat how you arrange your bedroom, and what you do before going to bed. ^[3][4]

Importance for Physical and Mental Health

Good sleep hygiene plays a crucial role in promoting overall well-being and mental health. ^[1] Poor sleep habits can exacerbate symptoms of mental health disorders like depression and anxiety, while the reverse is also true – mental health conditions can disrupt sleep patterns. ^[3]

Chronic sleep disruptions have been found to alter brain chemistry, potentially leading to the development of mental health issues. ^[4] Addressing both sleep hygiene and mental health together can be an effective path to optimal treatment.^[3]

Building Good Daytime Habits

Regular Exercise and Its Timing

Regular exercise has been found to promote better sleep quality and alleviate sleep-related issues. Studies suggest that moderate to vigorous exercise can increase sleep quality for adults by reducing the time it takes to fall asleep and decreasing the amount of time spent awake during the night.^{[5] [6]}

Exercise can also indirectly improve sleep by reducing the risk of excessive weight gain, which is a contributing factor to obstructive sleep apnea (OSA).^[5]

The timing of exercise can also impact sleep quality. Late-night exercise, particularly within an hour before bedtime, may affect sleep efficiency and total sleep time due to increased core body temperature. However, some individuals report better sleep when exercising later in the evening. The ideal exercise window for most people is between 4 p.m. and 8 p.m. ^[5]

Healthy Diet and Hydration

Proper nutrition and hydration play a crucial role in promoting quality sleep. Diets low in fiber, high in saturated fat, or high in sugar have been linked to less restorative sleep. Conversely, certain foods like tart cherry juice, kiwi fruit, fatty fish, and whole grains containing tryptophan may help improve sleep quality. ^[7]

Eating simple carbohydrates four hours before bedtime can aid in falling asleep faster, but a balanced diet with adequate amounts of carbohydrates, protein, and fat is recommended for long-term sleep health. Caffeine, alcohol, and high-fat or spicy foods, especially when consumed close to bedtime, can disrupt sleep and should be avoided. ^[7][8]

Managing Daytime Naps

Daytime naps can be beneficial when taken in moderation and at the right time. A nap between 20 and 30 minutes can enhance alertness, mood, and memory without causing grogginess. However, napping too close to bedtime or for extended periods may interfere with nighttime sleep quality. ^[9]

The ideal nap time for most adults is before 3 p.m., and napping in a cool, quiet, and dark environment can promote better sleep quality. Excessive daytime sleepiness may indicate an underlying sleep disorder and should be evaluated by a professional. ^[9

Optimizing Your Sleep Environment

Ideal Bedroom Conditions

Creating an ideal sleep environment is crucial for promoting quality rest. A relaxing ambiance is essential for a good night’s sleep, as studies have shown that people sleep better when their bedroom is optimized for temperature, noise, and light levels, as well as comfort. Temperature plays a vital role in sleep quality. Many experts recommend keeping the bedroom temperature between 65°F (18.3°C) and 71°F (22°C). ^[11]

Exposure to excessive heat can disrupt sleep, so erring on the cooler side is advisable ^[12] . Noise disturbances, even at low levels, can cause sleep fragmentation and disruption, leading to negative impacts on physical and mental health. ^[11] sing a white noise machine can help drown out external noises beyond your control. ^[12]

Light exposure in the evening can delay circadian rhythms and prolong sleep onset. Studies have found that exposure to light sources with a lux of 10 or higher later in the day can lead to more nocturnal awakenings and less restorative slow-wave sleep. ^[11] Ensuring a dark environment by blocking out external light sources is recommended for optimal sleep.

Additionally, maintaining good air quality by ensuring proper ventilation and reducing potential allergens like mold can contribute to better sleep quality. ^[12]

Choosing the Right Mattress and Pillow

The mattress and pillow play a crucial role in attaining restorative sleep and preserving overall health. The optimal combination can significantly affect sleep quality by fostering proper spinal alignment and minimizing discomfort.

When selecting a mattress, consider factors such as firmness, material (e.g., memory foam, latex, innerspring), and your body weight and sleeping position. Heavier individuals may require a firmer mattress to avoid excessive sinkage, while lighter individuals can opt for a softer mattress that conforms to their body contours. ^[13]

Similarly, the pillow’s loft (height) should be chosen based on shoulder width and neck length to maintain correct spine alignment and reduce strain. ^[13] For instance, side sleepers may benefit from a fuller, firmer pillow to support their head and take pressure off their shoulders. ^[14]

Individuals with specific health concerns, such as back pain or allergies, should select mattresses and pillows that address these issues. Memory foam mattresses can reduce back pain discomfort, while hypoallergenic materials like latex can minimize exposure to potential allergens. ^[13]

Using Sleep Tools

Incorporating sleep tools and gadgets can enhance the sleep environment and promote better rest. Devices like white noise machines, essential oil diffusers, and smart lighting systems can help create a calming atmosphere conducive to sleep^{. [11][12]}

Smart mattresses and pillows with adjustable firmness, temperature control, and position adjustment can provide personalized comfort and support throughout the night. ^[15] Sleep trackers can analyze the sleep environment and provide valuable insights into how factors like light, sound, temperature, and air quality affect sleep quality. ^[15]

Regularly washing bedding can also contribute to a fresh and comfortable sleep environment by reducing the buildup of dust mites, body oils, and other potential allergens. ^[11]

Creating Effective Nighttime Routines

Develop a Routine

A core element of sleep hygiene is making sure that daily habits work to promote consistent sleep. ^[16] Going to bed and waking up at the same time every day, including on weekends, helps regulate the body’s internal clock. ^[16] Following a steady routine before bed, such as winding down and relaxing for an hour, can signal to the body that it’s time to prepare for sleep. ^{[16] [[16]}

Pre-Bedtime Relaxation Activities

Engaging in relaxing activities before bedtime can ease the mind and body into a restful state. ^{[16] [19]} Enjoying a warm cup of non-caffeinated tea, taking a hot bath, listening to calming music, practicing guided meditation, or doing progressive muscle relaxation can promote relaxation. ^{[16] [19]} Reading a book with an uneventful plot, journaling, or making a to-do list for the next day can also be helpful pre-bedtime activities. ^[16]

Avoiding Disruptive Activities

Certain activities close to bedtime can interfere with the sleep cycle and should be avoided. Napping, especially in the late afternoon or evening, can disrupt the sleep-wake cycle. Consuming caffeine after noon, as its effects can last up to 8 hours, and drinking alcohol or having a large meal in the evening can also negatively impact sleep quality. ^[16]

Additionally, the blue light emitted by electronic devices like smartphones, tablets, and televisions can suppress melatonin production, making it harder to fall asleep, so it’s best to limit their use before bedtime. ^{[16] [19]}
