What You'll Learn
Stick to a sleep schedule
Sticking to a sleep schedule is a key part of maintaining good sleep hygiene. Sleep hygiene refers to the healthy habits, behaviours, and environmental factors that can be adjusted to help you get a good night's sleep.
Firstly, it is important to go to bed and wake up at the same time every day, even on the weekends. Maintaining a consistent sleep schedule helps to set and maintain the timing of your body clock, or circadian rhythm. This internal clock is partly controlled by an internal clock within the brain, which is influenced by the pattern of daylight where you live. By waking up at the same time every day, you will find yourself getting sleepy at roughly the same time every night.
However, it is also important not to ignore feelings of tiredness or force yourself to go to bed if you don't feel tired. If you go to bed when you're not tired, you risk reinforcing bad habits, such as lying awake in bed. Instead, listen to your body and go to bed when you feel ready.
If you often have trouble sleeping, or if you still feel tired after sleeping, consider keeping a sleep diary for a week and sharing it with your doctor. They may suggest different sleep routines or medicines to treat any underlying sleep disorders.

Avoid caffeine, nicotine, and alcohol
Consuming caffeine, nicotine, and alcohol can affect your sleep. Caffeine is a stimulant and the most widely consumed psychoactive drug in the world. It is commonly found in tea, coffee, chocolate, cola, and energy drinks. While it may not significantly affect sleep patterns for most people, it can make it harder to fall asleep and cause you to sleep more lightly. It is recommended to avoid caffeine at least two hours before bedtime.
Nicotine is also a stimulant that can promote alertness. Smoking or vaping before bed can make it harder to fall asleep and stay asleep. If you wake up during the night and consume nicotine, you may find it more difficult to fall back to sleep. It is best to avoid nicotine at least two hours before bedtime.
Many adults use alcohol to relax or as a nightcap. However, alcohol consumption before bed can negatively impact your sleep quality and quantity. It can increase sleep fragmentation and lower sleep efficiency. Even modest amounts of alcohol can significantly increase sleep disorders such as snoring, restless leg syndrome, and obstructive sleep apnea. It is recommended to avoid alcohol at least three to four hours before bedtime, although this may vary depending on individual factors such as sensitivity to alcohol and medication use.
In summary, avoiding caffeine, nicotine, and alcohol close to bedtime is a modifiable behavior that can significantly improve your sleep quality and continuity. It is essential to find alternative ways to relax before bed, such as adhering to a sleep schedule, maintaining a healthy diet, and practicing good sleep hygiene. Remember that the effects of these substances on sleep can vary between individuals, so it is important to listen to your body and make adjustments as needed.

Exercise and daylight exposure
Sun exposure is beneficial for your sleep, as it helps to regulate your body's internal clock, or circadian rhythm. Morning sunlight can help you sleep better at night, as it resets your body's inner "sleep clock". This is because sunlight affects your body's natural rhythms and sleep patterns. Sunlight also plays a role in regulating your hormones, including serotonin and melatonin, which are both important for sleep.
If you are unable to get outside, light therapy can be a helpful alternative. Light therapy uses a high-powered lamp to mimic daylight, which can be used to retrain the body's internal clock. This is often used in the morning to normalise circadian timing.
Exercising in the morning can also be a good way to get sunlight, and it is beneficial to stick to a regular schedule. This could be in the form of a walk, or even eating breakfast outside. If you are unable to get outside, it is still possible to get the benefits of sunlight on an overcast or cloudy day.

A comfortable sleep environment
Firstly, ensure your bedroom is dark. Invest in light-blocking curtains or shades to block out streetlights or early morning sunlight. Alternatively, consider using an eye mask to cover your eyes and block out light. This is especially useful if you work night shifts and need to sleep during the day.
Secondly, maintain a quiet bedroom. Keep noise to a minimum to promote a sleep-friendly space. If you cannot control external noise sources, consider using a fan, white noise machine, or earplugs to drown out the unwanted sounds.
Thirdly, maintain a comfortable temperature in your bedroom. The ideal temperature varies individually, but most research suggests sleeping in a slightly cooler room, around 65 to 68 degrees Fahrenheit. Ensure your bedding helps maintain a pleasant sleeping temperature. Choose sheets and blankets that feel comfortable and breathable.
Additionally, invest in a supportive mattress and pillow. Ensure they provide the correct level of support and comfort for your body. A good mattress and pillow are vital to ensuring your spine is properly aligned and supported, preventing aches and pains.
Lastly, reserve your bed for sleeping and intimacy only. Avoid using your bed for activities such as watching TV, working, or talking on the phone. This helps train your mind to associate your bed solely with sleep and relaxation.

Treating sleep disorders
Sleep is essential for our health and emotional well-being. Lack of sleep can lead to weight gain, impaired blood sugar control, and an increased risk of various diseases and disorders, including heart disease, stroke, obesity, and dementia. If you're struggling to get enough sleep, there are several strategies and treatments that can help you improve your sleep quality.
Maintain Good Sleep Habits
Good sleep habits, also known as sleep hygiene, are essential for improving sleep quality. This includes sticking to a consistent sleep schedule by going to bed and waking up at the same time every day, even on weekends. Maintaining a strict routine helps set your body's internal clock, making it easier to fall asleep and wake up at the same time each day. Additionally, limit daytime naps to 20 minutes or less if you have trouble sleeping at night.
Create a Sleep-Conducive Environment
Your bedroom should be dark, quiet, and comfortable. Use blackout curtains or an eye mask to block out excess light, and minimize noise with earplugs, a fan, or white noise machine. Maintain a cool temperature in the room, somewhere between 65 to 68 degrees Fahrenheit. Ensure your bed is comfortable and provides proper support for your spine. Reserve your bed solely for sleeping and intimacy, avoiding activities like watching TV or talking on the phone in bed.
Lifestyle and Behavioural Adjustments
Get some exercise every day, preferably earlier in the day rather than close to bedtime. Spend time outdoors in natural daylight, especially during the early morning, to help set your body clock. Limit caffeine intake, especially later in the day, and if you consume alcohol, do so in moderation. Avoid smoking, as nicotine is a stimulant that can disrupt your sleep. If you find yourself lying awake at night worrying, try stress management techniques or do something relaxing like reading or meditating until you feel sleepy.
Seek Professional Help
If you've tried improving your sleep hygiene and making lifestyle adjustments without success, consider seeking professional help. Talk to your healthcare provider about your sleep issues, and they may recommend different sleep routines, medications, or refer you to a sleep specialist. Cognitive behavioural therapy (CBT) has been shown to help people with insomnia, and specific treatments like CPAP machines and mouthguards can benefit those with sleep apnea. Keeping a sleep diary for a week and sharing it with your doctor can help them better understand your sleep patterns and make more targeted recommendations.
