Here are 17 evidence-based tips to sleep better at night.

Updated: Jun 24

1. Increase Bright Light Exposure During The Day


Your body has a natural time-keeping clock known as your circadian rhythm

It affects your brain, body and hormones, helping you stay awake and telling your body when it's time to sleep.

Natural sunlight or bright light during the day helps keep your circadian rhythm healthy. This improves daytime energy, as well as nighttime sleep quality and duration.

In people with insomnia, daytime bright light exposure improved sleep quality and duration. It also reduced the time it took to fall asleep by 83% .

A similar study in older adults found that two hours of bright light exposure during the day increased the amount of sleep by two hours and sleep efficiency by 80% .

While most research is in people with severe sleep issues, daily light exposure will most likely help you even if you experience average sleep.

Try getting daily sunlight exposure or — if this is not practical — invest in an artificial bright-light device or bulbs.


2. Reduce Blue Light Exposure in the Evening


Exposure to light during the day is beneficial, but nighttime light exposure has the opposite effect.

Again, this is due to its impact on your circadian rhythm, tricking your brain into thinking it is still daytime. This reduces hormones like melatonin, which help you relax and get deep sleep .

Blue light — which electronic devices like smartphones and computers emit in large amounts — is the worst in this regard.

There are several popular methods you can use to reduce nighttime blue light exposure. These include:

Wear glasses that block blue light.

Download an app such as f.lux to block blue light on your laptop or computer.

Install an app that blocks blue light on your smartphone. These are available for both iPhones and Android models.

Stop watching TV and turn off any bright lights two hours before heading to bed.


3. Don't Consume Caffeine Late in the Day


Caffeine has numerous benefits and is consumed by 90% of the US population.

A single dose can enhance focus, energy and sports performance.

However, when consumed late in the day, coffee stimulates your nervous system and may stop your body from naturally relaxing at night.

In one study, consuming caffeine up to six hours before bed significantly worsened sleep quality.

Caffeine can stay elevated in your blood for 6–8 hours. Therefore, drinking large amounts of coffee after 3–4 p.m. is not recommended — especially if you are sensitive to caffeine or have trouble sleeping.

If you do crave a cup of coffee in the late afternoon or evening, stick with decaf coffee.


4. Reduce Irregular or Long Daytime Naps


While short power naps are beneficial, long or irregular napping during the day can negatively affect your sleep.

Sleeping in the daytime can confuse your internal clock, meaning that you may struggle to sleep at night

In fact, in one study, participants ended up being sleepier during the day after taking daytime naps.

Another study noted that while napping for 30 minutes or less can enhance daytime brain function, longer naps can negatively affect health and sleep quality .

However, some studies demonstrate that those who are used to taking regular daytime naps do not experience poor sleep quality or disrupted sleep at night.

If you take regular daytime naps and sleep well, you shouldn’t have to worry. The effects of napping depend on the individual.


5. Try to Sleep and Wake at Consistent Times


Your body's circadian rhythm functions on a set loop, aligning itself with sunrise and sunset.

Being consistent with your sleep and waking times can aid long-term sleep quality .

One study noted that participants who had irregular sleeping patterns and went to bed late on the weekends reported poor sleep.

Other studies have highlighted that irregular sleep patterns can alter your circadian rhythm and levels of melatonin, which signal your brain to sleep.

If you struggle with sleep, try to get in the habit of waking up and going to bed at similar times. After several weeks, you may not even need an alarm.


6. Take a Melatonin Supplement


Melatonin is a key sleep hormone that tells your brain when it's time to relax and head to bed.

Melatonin supplements are an extremely popular sleep aid.

Often used to treat insomnia, melatonin may be one of the easiest ways to fall asleep faster.

In one study, 2 mg of melatonin before bed improved sleep quality and energy the next day and helped people fall asleep faster. In another study, half of the group fell asleep faster and had a 15% improvement in sleep quality.

Additionally, no withdrawal effects were reported in either of the above studies.

Melatonin is also useful when traveling and adjusting to a new time zone, as it helps your body's circadian rhythm return to normal.

In some countries, you need a prescription for melatonin. In others, melatonin is widely available in stores or online. Take around 1–5 mg 30–60 minutes before bed.

Start with a low dose to assess your tolerance, and then increase it slowly as needed. Since melatonin may alter brain chemistry, it is advised that you check with a medical professional before use.

You should also speak with a healthcare provider if you're thinking about using melatonin as a sleep aid for your child, as long-term use of this supplement in children has not been well studied.


7. Consider These Other Supplements


Several supplements can induce relaxation and help you sleep, including:

Ginkgo biloba: A natural herb with many benefits, it may aid in sleep, relaxation and stress reduction, but the evidence is limited. Take 250 mg 30–60 minutes before bed.

Glycine: A few studies show that 3 grams of the amino acid glycine can improve sleep quality.

Valerian root: Several studies suggest that valerian can help you fall asleep and improve sleep quality. Take 500 mg before bed

Magnesium: Responsible for over 600 reactions within your body, magnesium can improve relaxation and enhance sleep quality

L-theanine: An amino acid, l-theanine can improve relaxation and sleep. Take 100–200 mg before bed

Lavender: A powerful herb with many health benefits, lavender can induce a calming and sedentary effect to improve sleep. Take 80–160 mg containing 25–46% linalool

Make sure to only try these supplements one at a time. While they are no magic bullet for sleep issues, they can be useful when combined with other natural sleeping strategies.


8. Don't Drink Alcohol


Downing a couple of drinks at night can negatively affect your sleep and hormones.

Alcohol is known to cause or increase the symptoms of sleep apnea, snoring and disrupted sleep patterns

It also alters nighttime melatonin production, which plays a key role in your body's circadian rhythm

Another study found that alcohol consumption at night decreased the natural nighttime elevations in human growth hormone (HGH), which plays a role in your circadian rhythm and has many other key functions


9. Optimize Your Bedroom Environment


Many people believe that the bedroom environment and its setup are key factors in getting a good night's sleep.

These factors include temperature, noise, external lights and furniture arrangement

Numerous studies point out that external noise, often from traffic, can cause poor sleep and long-term health issues

In one study on the bedroom environment of women, around 50% of participants noticed improved sleep quality when noise and light diminished

To optimize your bedroom environment, try to minimize external noise, light and artificial lights from devices like alarm clocks. Make sure your bedroom is a quiet, relaxing, clean and enjoyable place.


10. Set Your Bedroom Temperature


Body and bedroom temperature can also profoundly impact sleep quality.

As you may have experienced during the summer or in hot locations, it can be very hard to get a good night's sleep when it's too warm.

One study found that bedroom temperature affected sleep quality more than external noise

Other studies reveal that increased body and bedroom temperature can decrease sleep quality and increase wakefulness

Around 70°F (20°C) seems to be a comfortable temperature for most people, although it depends on your preferences and habits.


11. Don't Eat Late in the Evening


Late-night eating may negatively impact both sleep quality and the natural release of HGH and melatonin

That said, the quality and type of your late-night snack may play a role as well.

In one study, a high-carb meal eaten four hours before bed helped people fall asleep faster

Interestingly, one study discovered that a low-carb diet also improved sleep, indicating that carbs are not always necessary — especially if you are used to a low-carb diet


12. Relax and Clear Your Mind in the Evening


Many people have a pre-sleep routine that helps them relax.

Relaxation techniques before bed have been shown to improve sleep quality and are another common technique used to treat insomnia

In one study, a relaxing massage improved sleep quality in people who were ill

Strategies include listening to relaxing music, reading a book, taking a hot bath, meditating, deep breathing and visualization.

Try out different methods and find what works best for you.


13. Take a Relaxing Bath or Shower


A relaxing bath or shower is another popular way to sleep better.

Studies indicate that they can improve overall sleep quality and help people — especially older adults — fall asleep faster

In one study, a hot bath 90 minutes before bed improved sleep quality and helped people get more deep sleep

Alternatively, if you don't want to take a full bath at night, simply bathing your feet in hot water can help you relax and improve sleep


14. Rule Out a Sleep Disorder


An underlying health condition may be the cause of your sleep problems.

One common issue is sleep apnea, which causes inconsistent and interrupted breathing. People with this disorder stop breathing repeatedly while sleeping

This condition may be more common than you think. One review claimed that 24% of men and 9% of women have sleep apnea

Other common medically diagnosed issues include sleep movement disorders and circadian rhythm sleep/wake disorders, which are common in shift workers

If you've always struggled with sleep, it may be wise to consult with your doctor.


15. Get a Comfortable Bed, Mattress and Pillow


Some people wonder why they always sleep better in a hotel.

Apart from the relaxing environment, bed quality can also affect sleep

One study looked at the benefits of a new mattress for 28 days, revealing that it reduced back pain by 57%, shoulder pain by 60% and back stiffness by 59%. It also improved sleep quality by 60%

Other studies point out that new bedding can enhance sleep. Additionally, poor-quality bedding can lead to increased lower-back pain

The best mattress and bedding is extremely subjective. If you are upgrading your bedding, base your choice on personal preference

It is recommended that you upgrade your bedding at least every 5–8 years.

If you haven't replaced your mattress or bedding for several years, this can be a very quick — although possibly expensive — fix


16. Exercise Regularly — But Not Before Bed


Exercise is one of the best science-backed ways to improve your sleep and health.

It can enhance all aspects of sleep and has been used to reduce symptoms of insomnia

One study in older adults determined that exercise nearly halved the amount of time it took to fall asleep and provided 41 more minutes of sleep at night

In people with severe insomnia, exercise offered more benefits than most drugs. Exercise reduced time to fall asleep by 55%, total night wakefulness by 30% and anxiety by 15% while increasing total sleep time by 18%

Although daily exercise is key for a good night's sleep, performing it too late in the day may cause sleep problems.

This is due to the stimulatory effect of exercise, which increases alertness and hormones like epinephrine and adrenaline. However, some studies show no detrimental effects, so it clearly depends on the individual


17. Don't Drink Any Liquids Before Bed


Nocturia is the medical term for excessive urination during the night. It affects sleep quality and daytime energy

Drinking large amounts of liquids before bed can lead to similar symptoms, though some people are more sensitive than others.


Although hydration is vital for your health, it is wise to reduce your fluid intake in the late evening.

Try not to drink any fluids 1–2 hours before going to bed.

You should also use the bathroom right before going to bed, as this may decrease your chances of waking in the night.


The Bottom Line

Sleep plays a key role in your health.

One large review linked insufficient sleep to an increased obesity risk of 89% in children and 55% in adults

Other studies conclude that less than 7–8 hours per night increases your risk of developing heart disease and type 2 diabetes.

If you are interested in optimal health and wellbeing, then you should make sleep a top priority and incorporate some of the tips above.
