Sleep is essential for our physical and mental well-being, but many people struggle to get enough quality sleep. To improve your sleep, you can make changes to your diet and lifestyle, such as spending time in natural sunlight, avoiding screens before bed, and cutting back on caffeine and alcohol. You can also try natural sleep aids like melatonin supplements, chamomile tea, and valerian. If you're waking up in the middle of the night, try to avoid turning on the lights or looking at the time, as this can increase stress and make it harder to fall back asleep. Instead, focus on relaxing activities like quiet reading or listening to music. Maintaining a consistent sleep schedule and creating a comfortable sleep environment are also key to improving your sleep.

What You'll Learn
Stick to a sleep schedule
Sticking to a sleep schedule is one of the most important things you can do to improve your sleep quality. Sleep is just as important for your health as regular exercise and a healthy diet, and poor sleep can negatively impact your thinking ability, mood, heart health, and immune health.
The first step to sticking to a sleep schedule is to understand the benefits of getting enough quality sleep. By prioritizing sleep, you are more likely to maintain a consistent sleep schedule. The next step is to pick a bedtime and wake-up time that allows you to get sufficient sleep and then stick to it as closely as possible. Consistency is key, even on weekends and holidays. Your body's circadian rhythm functions on a set loop, aligning with sunrise and sunset, so it's important to synchronize your sleep schedule with daylight hours. This means winding down and getting ready for bed when it gets dark in the evening and waking up around the start of daylight hours.
It may take some time to adjust to a new sleep schedule, but there are several techniques to help you stick to it. You can set reminders on your phone to alert you when it's time to start your bedtime routine, and you can use a wake-up alarm to ensure you don't oversleep in the morning. You can also focus on creating a fixed wake-up time first and then gradually adjust your bedtime using good sleep hygiene habits.
In addition to improving your sleep hygiene, you may want to discuss taking supplements with your doctor. Melatonin supplements are commonly used to aid sleep and are available over the counter. However, it's important to note that they are not regulated by the FDA, so dosages and ingredients may vary between manufacturers. Natural sleep aids such as valerian, chamomile, and glycine may also be beneficial.

Avoid screens and bright lights before bed
Light exposure within two hours of bedtime can be disruptive to your sleep cycle. This is because exposure to blue light at night stimulates your brain into thinking it's still daytime. As a result, your brain slows or stops its release of melatonin, making it harder to fall asleep.
Blue light has shorter wavelengths than other colours in the visible light spectrum and causes more alertness than warmer light tones. Blue wavelengths boost attention, reaction times, and mood during the day, but they are the most disruptive at night. The proliferation of electronics with screens and energy-efficient lighting has increased our exposure to blue light, especially after sundown.
Harvard researchers and their colleagues conducted an experiment comparing the effects of blue light and green light. They found that blue light suppressed melatonin for about twice as long as green light and shifted circadian rhythms by twice as much. Even dim light can interfere with a person's circadian rhythm and melatonin secretion.
To avoid the negative impacts of blue light on your sleep, try to avoid looking at bright screens beginning two to three hours before bed. If you must use electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength. Exposing yourself to bright light during the day can also boost your ability to sleep at night and improve your mood and alertness.

Make your bedroom a dark, cool sanctuary
A good night's sleep is essential for your health, so it's important to make your bedroom a sanctuary for rest and relaxation. Here are some tips to make your bedroom a dark, cool haven for sleep:
Firstly, eliminate electronics and clutter. Keeping your space minimal and free from screens will give your mind peace and help you prepare for sleep. This includes removing or reducing light-emitting devices like phones, laptops, and TVs, which can prevent the release of the sleep hormone melatonin. If you must use your phone, consider installing a blue light filter to reduce the impact on your sleep.
Next, embrace the darkness. Choose dark, rich colours for your walls, such as deep jewel tones, a moody plum, or a sophisticated charcoal grey. These shades will create a cohesive and inviting atmosphere. You can also add a touch of soft, warm string lights to create a magical vibe, but ensure they're not too bright. Opt for dark-coloured bedding and furniture, too. Dark wood furniture, like walnut or mahogany, will complement the dark walls and add a sense of sophistication.
To enhance the relaxing ambiance, consider adding some spa-inspired accessories. Battery-operated candles, essential oil diffusers, and soft lighting can all contribute to a zen-like space. A comfortable armchair with a plush cushion and soft fabric can create a cozy reading nook, especially when placed near a window or lamp for the perfect lighting.
Finally, pay attention to your bedding. Make your bed each morning, adding throw pillows and interesting textures like pom-pom quilts, velvet pillows, or faux fur throws. Layer your bedding so you can adjust your bedtime temperature as needed. A comfortable, inviting bed will make all the difference in creating a sanctuary for sleep.
By following these steps and making your bedroom a dark, cool sanctuary, you'll be well on your way to improving your sleep hygiene and getting the rest you need.

Try natural sleep aids like chamomile tea or melatonin supplements
Natural sleep aids can be a great way to improve your sleep quality without the side effects or drug interactions that may come with prescription sleep aids. Two of the most popular natural sleep aids are chamomile tea and melatonin supplements.
Chamomile Tea
Chamomile tea is an herbal tea that has been used to promote relaxation and sleep since ancient times. It is naturally caffeine-free, but it is still important to check the label before drinking chamomile tea to ensure that it has not been combined with another type of tea that contains caffeine. Research suggests that chamomile tea may help improve sleep quality and reduce the number of awakenings after sleep. It is also believed to have flavonoids that may interact with benzodiazepine receptors in the brain involved in the sleep-wake transition. The optimal time to drink chamomile tea is 45-60 minutes before bedtime or during wind-down time.
Melatonin Supplements
Melatonin is a hormone that is naturally produced by the body and helps signal to the brain that it is time to sleep. Melatonin supplements have become a popular sleep aid, especially for those experiencing insomnia, jet lag, or a delayed sleep phase. When taking melatonin supplements, it is recommended to start with a lower dosage of 1 to 3 milligrams two hours before bedtime. It is also important to note that melatonin supplements are not regulated by the FDA, so it is essential to consistently buy the same brand and consult your doctor before taking them, especially if you are pregnant or breastfeeding or have certain health conditions.
In addition to natural sleep aids, improving your overall sleep hygiene is crucial for getting a good night's sleep. This includes practices such as maintaining a consistent sleep schedule, limiting exposure to blue light before bed, and creating a relaxing bedtime routine through activities such as quiet reading or listening to soothing music.

Avoid large meals, alcohol, and caffeine before bed
While a nightcap may seem like a good way to unwind, alcohol should be avoided close to bedtime. Experts recommend refraining from drinking alcohol at least 3 hours before bed. Alcohol can cause frequent wakings and negatively impact your overall sleep quality. Long-term alcohol use can even lead to chronic sleep issues such as sleep apnea. It is better to opt for a non-alcoholic drink such as warm milk, chamomile tea, or tart cherry juice, which are all recommended for aiding sleep.
Caffeine is another substance that should be avoided before bed. Caffeine has been used as a model of insomnia in studies, and it is widely recommended to refrain from consuming it close to bedtime. The specific timeframes vary, with some sources suggesting 4 hours and others suggesting up to 11 hours before bedtime. Caffeine can cause significant sleep disturbances, so it is best to limit your intake or avoid it altogether if you plan to get a good night's rest.
When it comes to food, it is best to avoid large meals 2 to 4 hours before bedtime. Eating a high-calorie meal with large amounts of fat or carbohydrates less than an hour before bed can make it harder to fall asleep. It can also increase the likelihood of waking up in the middle of the night. Instead, opt for a light snack that is easily digestible and low in calories. This will help appease any hunger cravings without disrupting your sleep.
If you are prone to acid reflux, it is especially important to avoid eating large meals before bed. Eating too close to bedtime can trigger gastroesophageal reflux disease (GERD) or acid reflux. It is recommended to avoid lying down immediately after eating and to allow some time for digestion.
