Enhancing Sleep Quality: Simple Tips For Better Rest

Sleep is an essential pillar of health, alongside exercise and a healthy diet. Poor sleep can negatively impact your thinking ability, mood, heart health, immune health, and more. It can also increase your chances of developing obesity and diabetes. So, what can be done to improve your sleep?

Firstly, it is important to optimise your bedroom environment. This includes reducing noise and light levels, as well as maintaining a comfortable temperature. You should also invest in a good quality mattress and bedding. In addition, you can improve your sleep by making changes to your diet and lifestyle. For example, reducing your caffeine and alcohol intake, particularly later in the day, and avoiding eating large meals close to bedtime. Regular exercise can also help promote better sleep, but it is important to avoid intense exercise close to bedtime as this may hinder your body's ability to settle down before sleep.

Avoid caffeine, nicotine and alcohol before bed

Caffeine, nicotine, and alcohol are all stimulants that can make us more alert and affect our sleep. It is recommended that you avoid these substances close to bedtime to improve your sleep quality.

Caffeine is known to negatively impact sleep, especially when consumed late in the day. A 2023 research review found that consuming caffeine late in the day reduced total sleep time by 45 minutes and decreased sleep efficiency by 7%. Caffeine may also negatively affect REM sleep. To improve your sleep, it is advisable to avoid caffeinated beverages at least 8 hours before bedtime. If you must have a caffeinated drink in the late afternoon or evening, opt for decaffeinated coffee or tea.

Nicotine is also a stimulant that can disrupt sleep. Evening nicotine use has been linked to sleep disturbances, making it more difficult to fall asleep and leading to fragmented sleep. If you smoke, try to avoid doing so in the hours leading up to bedtime. If you live with smokers, take steps to avoid secondhand smoke exposure, as this has also been associated with sleep problems.

While alcohol may make you feel drowsy initially, it can disrupt your sleep later in the night. Alcohol affects the brain in ways that lower sleep quality and can cause or worsen sleep apnea, snoring, and disrupted sleep patterns. It also interferes with the production of melatonin, a key sleep hormone. To improve your sleep, avoid consuming alcohol close to bedtime.

By avoiding caffeine, nicotine, and alcohol before bed, you can create a more conducive environment for restful sleep and improve your overall sleep quality.

Exercise daily, but not too close to bedtime

Exercise is an important part of improving your sleep quality. However, it is crucial to avoid exercising too late in the day, as this may cause sleep problems.

Daily exercise has numerous health benefits, and it can also promote solid sleep. Most experts recommend avoiding vigorous exercise close to bedtime because it may hinder your body's ability to settle down before sleep. The stimulatory effect of exercise increases alertness and the levels of hormones such as epinephrine and adrenaline. Therefore, it is advisable to finish any intense workouts at least a few hours before bedtime.

Moderate aerobic exercise is particularly beneficial for improving sleep. It boosts the amount of nourishing slow-wave (deep) sleep you get. Additionally, aerobic exercise releases endorphins, which can keep you awake, so it is best to avoid aerobic workouts within two hours of bedtime.

Gentle mind-body exercises, such as yoga or tai chi, are excellent choices for just before bed. These activities can help relax your body and mind, preparing you for a good night's sleep.

Exercising daily and timing your workouts appropriately can significantly improve your sleep quality. By incorporating exercise into your daily routine and ensuring you leave enough time between your workout and bedtime, you will be well on your way to enjoying a better night's rest.

Optimise your bedroom environment

Your bedroom environment is key to achieving a good night's sleep. It's not just about having a comfortable bed or bedding, but also about creating a sleep-friendly space. Here are some tips to optimise your bedroom environment:

• Minimise external noise by keeping the bedroom quiet. If you can't eliminate nearby sources of noise, consider using a fan or white noise machine to drown them out. Alternatively, you can use earplugs or headphones to block out the sounds.
• Reduce light exposure by minimising external light sources and artificial lights from devices such as alarm clocks. Use blackout curtains or a sleep mask to block light from windows.
• Maintain a comfortable temperature. The ideal temperature varies based on individual preferences, but most people find that a cooler room, around 65 to 68 degrees Fahrenheit (18.3 to 20 degrees Celsius), is most conducive to sleep.
• Improve air quality by ensuring proper ventilation in the bedroom.
• Keep your bedroom dark. Avoid turning on bright lights if you need to get up at night, and instead use a flashlight or nightlight to minimise visual disruption.
• Create a relaxing atmosphere by playing ambient sounds such as rainfall or gentle music, or using white noise.
• Keep your phone on silent or out of the room entirely to ensure a quiet environment.
• Use good curtains or blinds to block out unwanted light and keep the room dark.
• Ensure your room is well-ventilated to maintain a comfortable temperature and improve air quality.

Stick to a sleep schedule

Sticking to a sleep schedule is one of the most important things you can do to improve your sleep. Our bodies have an internal clock, known as the circadian rhythm, which is aligned with sunrise and sunset. By keeping a consistent sleep schedule, you can train your body to be ready for sleep at the same time every day.

• Set a bedtime and wake-up time: Determine a bedtime that allows you to get at least seven hours of sleep. Calculate this based on your fixed wake-up time, which should remain consistent, even on weekends.
• Be consistent: Stick to your chosen bedtime and wake-up time every day. Over time, your body will adjust to this routine, making it easier to fall asleep and wake up.
• Avoid napping: Naps can disrupt your sleep schedule, especially if they are too long or too late in the day. If you must nap, aim for a 20-minute power nap in the early afternoon.
• Wind down before bed: Start your bedtime routine 30 minutes to an hour before your chosen bedtime. During this time, engage in relaxing activities such as reading, listening to soothing music, or practising relaxation techniques like meditation or deep breathing.
• Optimise your bedroom environment: Create a sleep-friendly space by minimising noise, light, and artificial lights from electronic devices. Keep your bedroom at a comfortable temperature, typically between 65°F and 68°F (18.3°C to 20°C).
• Limit stimulants: Avoid caffeine, nicotine, and alcohol close to bedtime. These substances can interfere with your sleep and make it harder to fall asleep. Aim to limit stimulants at least one to two hours before bed.

Try supplements and natural remedies

Supplements and natural remedies can be a great way to improve your sleep quality. Here are some tips to help you sleep better:

Melatonin Supplements

Melatonin is a key sleep hormone that signals to your brain when it's time to relax and go to bed. Taking melatonin supplements can help you fall asleep faster. These supplements are widely available over the counter and can be purchased at your local pharmacy. However, it's important to note that melatonin is not regulated by the FDA, so dosages and ingredients may vary between manufacturers. Consult with a healthcare professional before taking melatonin, especially if you intend to give it to a child.

Valerian, Chamomile, and Glycine

In addition to melatonin, other natural sleep aids include valerian, chamomile, and glycine. These supplements can help you relax and improve your sleep quality when combined with other strategies. When trying out these supplements, test them one at a time to ensure they have the desired effect on your sleep and to avoid any negative reactions.

Warm Milk, Chamomile Tea, and Tart Cherry Juice

Although there isn't extensive scientific evidence, some natural drinks may help improve your sleep. Warm milk, for example, is believed to contain chemicals that simulate the effects of tryptophan, a building block for serotonin, which plays a role in the sleep-wake transition. Chamomile tea is also recommended as it contains flavonoids that may interact with receptors in the brain involved in the sleep-wake transition. Additionally, tart cherry juice may support melatonin production and promote a healthy sleep cycle.

Exercise

Engaging in physical exercise during the day can improve your sleep. Moderate aerobic exercise increases the amount of nourishing slow-wave (deep) sleep you get. However, it's important to time your workouts correctly. Avoid exercising within two hours of your bedtime, as aerobic exercise releases endorphins that can keep you awake and raises your core body temperature, making it harder to fall asleep.

Bedroom Environment

Creating a sleep-friendly bedroom environment is crucial for improving sleep quality. This includes minimizing noise, light, and artificial lights from electronic devices. Keep your bedroom at a comfortable temperature, typically between 65°F and 68°F (18.3°C to 20°C), as this range is generally considered ideal for most people.
