This article aims to provide evidence-based tips for improving sleep quality, employing scientific research and expert recommendations. These strategies encompass natural supplements and remedies, the creation of a sleep-friendly environment, and the management of sleep disorders like sleep apnoea and insomnia.

By incorporating these tips into one's daily routine, you may enhance the quality and duration of your sleep, leading to improved physical and mental health outcomes. Remember, the effectiveness of these strategies may vary depending on individual circumstances, and it is advisable to consult with a healthcare professional for personalised advice.


Key Takeaways

  • Natural sleep aids like magnesium, calcium, glycine, theanine, valerian, and passion flower can help improve sleep.
  • Maintaining a consistent sleep schedule and developing a relaxing bedtime routine, like meditation for sleep, can enhance sleep quality.
  • Avoid blue light exposure in the evening and use blue light lamps or wake-up light alarm clocks to regulate sleep patterns.
  • Avoid caffeine, nicotine, and alcohol close to bedtime, exercise regularly but not too close to bedtime, and manage nighttime anxiety through relaxation techniques.

How to Improve Sleep Quality

Enhancing sleep quality involves behavioural approaches such as creating a sleep-friendly environment, establishing a consistent sleep schedule, and developing a relaxing bedtime routine.

A sleep-friendly environment entails keeping the bedroom cool, dark, and quiet, using light pollution-blocking tools, investing in comfortable bed accessories, and using white noise or calming sounds to counteract sleep disruptions[1]

Establishing a consistent sleep schedule helps regulate the body's internal clock and promotes a regular sleep-wake cycle. This means going to bed and waking up at the same time every day, even on weekends [2]

Developing a relaxing bedtime routine, such as reading before bed, practising relaxation techniques, or engaging in calming activities, can signal to the body that it is time to sleep.

Natural Supplements and Remedies

Magnesium, calcium, glycine, theanine, valerian, and passion flower are recommended sleep supplements. They have been studied for their potential effects on sleep and relaxation.

Magnesium is involved in numerous biochemical reactions in the body, including sleep regulation. Calcium is crucial for muscle relaxation and promotes better sleep. Glycine, an amino acid, may enhance sleep quality by reducing body temperature and promoting relaxation. Theanine, another amino acid found in green tea, can increase sleep quality and reduce anxiety. Valerian root and passion flower have been traditionally used for their calming properties and may promote better sleep [3]

While these sleep-promoting foods and supplements show promise, it's crucial to consult with a healthcare professional before starting any new regimen.

Creating a Sleep-Friendly Environment

Creating an environment conducive to sleep is essential for improving sleep quality. Here are key elements to consider when creating a sleep-friendly environment:

  1. Bedroom Conditions: Keep the bedroom cool, ensure the room is dark by using blackout curtains or eye masks, and minimise noise disruptions.

  2. Sleep Schedule and Routine: Establish a consistent sleep schedule and develop a relaxing bedtime routine, which could include activities like reading or practising meditation for sleep.

  3. Comfortable Sleep Environment: Invest in comfortable bed accessories, create a clutter-free environment, and maintain a suitable bedroom temperature to promote deeper sleep.

Managing Sleep Disorders

For addressing sleep disorders, it's effective to seek professional help and potentially undergo a sleep study. Sleep disorders can have various causes such as sleep apnoea, restless leg syndrome, or medication side effects. Consulting a doctor or sleep specialist can help identify the specific condition and develop an appropriate treatment plan.

A sleep study, also known as polysomnography, involves monitoring various physiological parameters during sleep, providing valuable insights into the nature and severity of the sleep disorder, which can guide the selection of appropriate interventions [4]


In conclusion, optimising sleep quality is vital for overall health and well-being. By employing science-based strategies, such as incorporating sleep-promoting foods and supplements, creating a sleep-friendly environment, and managing sleep disorders, individuals can enhance their sleep patterns.

Also, adopting a healthy lifestyle, including managing nighttime anxiety, can significantly improve sleep quality. By following these science-based tips, individuals can make significant strides in enhancing their sleep quality and overall health.
