What You'll Learn

Relaxing activities before bedtime
Sleep hygiene refers to a set of healthy habits and behaviours that promote better sleep. It involves practices that help you get regular, restful sleep and improve your overall physical and mental health.
Create a Relaxing Environment
Dim the lights and ensure your bedroom is dark when it's time to sleep. Adjust the thermostat to a comfortable temperature, and consider using scented moisturisers or oils to create a soothing atmosphere.
Listen to Calming Music or Sounds
Instead of scrolling through your phone, listen to calming music, white noise, or nature sounds like rain or a crackling fire. Apps like Calm offer soundscapes and sleep stories to help you relax and drift off.
Read or Listen to Audiobooks
Choose something easy and relaxing to read, such as short stories, children's books, or poetry. Alternatively, listen to audiobooks or podcasts in a similar vein. If you have ADHD, consider listening to old-timey radio shows or books you've already read to avoid staying awake to hear what happens next.
Journaling
Spend some time writing down your plans for the next day, reflecting on what you're grateful for, or simply jotting down your thoughts about the day's events. Journaling can help clear your mind and reduce worries that may interfere with sleep.
Breathing and Relaxation Exercises
Practice deep breathing exercises like diaphragmatic breathing to activate your body's natural relaxation response. Visualization exercises and body scans, which involve focusing on different parts of your body and releasing tension, can also help you relax and prepare for sleep.
These activities can help you establish a healthy sleep routine and improve your overall sleep hygiene. Remember, the key is to find what works best for you and to be consistent in your practices.

Consistent sleep schedule
Sleep hygiene refers to a set of healthy habits and behaviours that promote better sleep. It involves behavioural and environmental practices that help people with mild to moderate insomnia.
A consistent sleep schedule is a crucial aspect of sleep hygiene. It involves going to bed and waking up at the same time each day. This helps establish a routine and improves the quality of sleep. Here are some tips to maintain a consistent sleep schedule:
- Stick to a sleep schedule: Try to go to bed and wake up at the same time every day, even on weekends or during holidays. This helps to regulate your body's internal clock and improve the quality of your sleep.
- Allow enough time for sleep: Ensure you are getting 7-9 hours of uninterrupted sleep each night. This is the recommended amount of sleep for adults to maintain optimal physical and mental health.
- Use naps with care: While naps can be helpful after a sleepless night, they may disrupt your nighttime sleep in the long term. Clinicians often advise obtaining the recommended hours of sleep at night instead of napping during the day.
- Avoid oversleeping: While getting enough sleep is important, oversleeping can also disrupt your sleep schedule. Set a consistent wake-up time and avoid sleeping in, even if you've had a late night.
- Gradually adjust your sleep schedule: If you need to change your sleep schedule, do so gradually. Shifting your bedtime or wake-up time by 15-30 minutes each day will help your body adjust more easily.
- Create a bedtime routine: Establish a relaxing bedtime routine that helps signal to your body that it's time to wind down. This could include activities such as reading, listening to soothing music, or practising meditation or deep breathing exercises.

Avoid stimulants
Sleep hygiene is a set of healthy habits and behaviours that promote better sleep. It impacts both the quality and quantity of sleep and plays a significant role in your physical and mental health.
Stimulants are substances that increase the level of some chemical messengers in the central nervous system, making a person more alert and energised. They also increase blood pressure and heart and breathing rates, stimulating the mind and body. These changes may make it difficult for a person to sleep, and stimulants may even be the cause of some sleep problems.
Caffeine is a well-known stimulant that can disrupt sleep. It is advised to limit caffeine intake, especially after the midday meal. Coffee and cough medicines are common culprits, but stimulants may also be found in other foods, drinks, medicines, and supplements. For example, traditional stimulants like amphetamines increase wake-promoting catecholamines, while caffeine blocks sleep-promoting adenosine receptors. CNS stimulants like pitolisant and solriamfetol are used to treat residual daytime sleepiness and narcolepsy but can cause insomnia and rebound hypersomnia.
If you are struggling with sleep, it is worth considering the stimulants that may be interfering with your sleep. A sleep program or coach can help identify these hidden stimulants. Behavioural therapy, relaxation techniques, exercise, and nutritional support are also recommended for a well-rounded treatment approach to improving sleep.

Healthy sleep environment
Sleep hygiene is a set of healthy habits and behaviours that promote better sleep. One of the key components of sleep hygiene is creating a healthy sleep environment.
A healthy sleep environment involves making your bedroom a peaceful, comfortable, and dark place. This means dimming the lights around bedtime and ensuring your room can be completely dark when it's time to sleep. Darkness is essential for the body to produce melatonin, the hormone that regulates sleep.
Keep your bedroom quiet and at a comfortable temperature. Noise is a common sleep disruptor, so consider using earplugs or a white noise machine if you can't control the noise in your environment.
Additionally, avoid using electronic devices at least 30-60 minutes before bed. The blue light emitted by screens can interfere with your sleep by suppressing melatonin production. Instead of screen time, engage in relaxing activities such as meditation, listening to calming music, journaling, or diffusing essential oils.
Finally, avoid consuming stimulants like caffeine and nicotine close to bedtime, as they can activate neurobiological systems that maintain wakefulness. Alcohol should also be avoided as it can disrupt sleep, despite initially inducing sleepiness.

Exercise earlier in the day
Sleep hygiene is a set of healthy habits and behaviours that promote better sleep. It involves practices that maintain health and prevent disease, impacting both physical and mental health.
Exercise is an important part of good sleep hygiene, but the timing of your workouts matters. Exercise stimulates the body by increasing energy levels and body temperature, which can make it harder to fall asleep. Therefore, it is recommended to exercise earlier in the day, preferably in the afternoon or early evening. This gives your body enough time to wind down before bed, promoting a good night's sleep.
Exercising earlier in the day can boost your overall sleep quality. Aim to finish your workout at least one to two hours before your bedtime. This timing ensures that the stimulating effects of exercise, such as increased heart rate and body temperature, have time to subside. By allowing your body to relax and cool down, you create an optimal environment for falling asleep quickly and comfortably.
If you prefer evening workouts, you can still exercise then, but be mindful that it may be more challenging to fall asleep right after. Listen to your body and experiment with different workout times to find what works best for you. Some people find that evening exercises help them sleep, while others may struggle with insomnia as a result.
If you exercise in the evening, consider opting for more gentle activities like yoga or stretching. These activities can help you relax and unwind while still getting the benefits of physical activity. Additionally, if you can't exercise outdoors, don't worry—regular indoor exercise can also improve your sleep quality.
