Getting enough good-quality sleep is essential for physical health, emotional balance, concentration, memory, and everyday functioning. Yet many people regularly struggle to fall asleep, remain asleep, or wake earlier than they intend.

Occasional sleeplessness can happen because of stress, changes in routine, illness, travel, or lifestyle habits. When sleep difficulties become frequent and begin affecting daytime life, they may be related to insomnia.

Fortunately, several evidence-informed approaches can help improve sleep. These include maintaining a consistent sleep schedule, managing stress, improving the bedroom environment, limiting stimulating activities before bed, exercising regularly, and addressing medical conditions that interfere with sleep.

This guide explains practical ways to improve sleep quality and manage insomnia.

What Is Insomnia?

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking earlier than desired. People with insomnia may also experience daytime problems such as tiredness, difficulty concentrating, impaired thinking, irritability, or changes in mood.

Not every night of poor sleep means that someone has insomnia. Temporary sleep disruption is common and may resolve when the underlying cause improves.

Insomnia can also involve early-morning awakening, sometimes called terminal insomnia, in which a person wakes significantly earlier than planned and cannot easily return to sleep.

The frequency and duration of symptoms are important when determining whether sleep difficulties meet the criteria for an insomnia disorder.

Acute vs. Chronic Insomnia

Insomnia can generally be described as acute or chronic depending on how long the problem persists.

• Acute insomnia: Short-term difficulty falling or staying asleep that lasts less than three months.
• Chronic insomnia: Sleep difficulties occurring at least three nights per week for three months or longer.

Persistent insomnia deserves attention because ongoing poor sleep can affect mood, thinking, daily performance, and overall quality of life.

What Causes Poor Sleep in Children and Adults?

Sleep problems can have many causes, and they may differ between children, adults, and older adults.

Sleep Problems in Children

Children may experience poor sleep because of:

• Irregular bedtime routines
• Excessive screen exposure
• Environmental disturbances
• Certain medical conditions
• Family or behavioral factors
• Individual or genetic differences

Creating a predictable bedtime routine and maintaining a suitable sleep environment can support healthier sleep habits.

Sleep Problems in Adults

Adults may experience insomnia or disrupted sleep in association with:

• Stress and anxiety
• Depression
• Chronic pain
• Cardiovascular disease
• Neurological or neurodegenerative conditions
• Substance use
• Poor sleep habits
• Irregular schedules

Older adults may also experience changes in sleep patterns as they age. Persistent insomnia can contribute to reduced quality of life and should be discussed with a healthcare professional when it continues.

How to Sleep Better With Insomnia

Improving sleep usually involves more than changing one habit. A combination of behavioral strategies, environmental changes, stress management, physical activity, and treatment of underlying conditions may provide better results.

1. Consider Cognitive Behavioral Therapy for Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured treatment designed specifically for people experiencing persistent sleep difficulties.

CBT-I may include several components, including:

• Sleep restriction therapy
• Stimulus control
• Cognitive therapy
• Sleep hygiene education
• Strategies for preventing relapse

The goal is to change behaviors and thought patterns that can maintain insomnia and to rebuild a healthier relationship between the bed and sleep.

Sleep Restriction Therapy

Sleep restriction therapy does not simply mean sleeping less. Instead, it initially reduces the amount of time spent awake in bed and gradually adjusts time in bed as sleep becomes more efficient.

This approach can help reduce prolonged periods of wakefulness during the night and improve sleep continuity.

Because sleep restriction can be demanding and may not be appropriate for everyone, it is best performed with appropriate professional guidance.

Stimulus Control Therapy

Stimulus control aims to strengthen the connection between bed and sleep while reducing the association between the bed and wakefulness.

For example:

• Go to bed when you feel sleepy.
• Avoid using the bed as a place for prolonged work or scrolling.
• If you remain awake for a long period, get out of bed and do something quiet until you feel sleepy again.
• Keep a consistent wake-up time.

These behaviors may be particularly useful when a person has developed anxiety or alertness around bedtime.

2. Keep a Sleep Diary

A sleep diary can help identify patterns that may be contributing to poor sleep.

You can record:

• Bedtime
• Approximate time you fall asleep
• Nighttime awakenings
• Wake-up time
• Naps
• Caffeine intake
• Exercise
• Screen use
• How rested you feel during the day

Looking at these patterns can make it easier to identify habits that interfere with sleep and discuss them with a healthcare professional.

Digital sleep-tracking tools can also provide information, although excessive focus on sleep measurements can sometimes increase anxiety about sleep.

3. Reduce Screen Use Before Bed

Phones, tablets, computers, and other digital devices can interfere with sleep when used excessively or immediately before bedtime.

Several factors may contribute, including:

• Exposure to light from screens
• Delayed bedtime
• Mental stimulation
• Work-related stress
• Social media activity
• Doomscrolling

Try establishing a screen-free wind-down period before going to bed. Avoid reading stressful work messages or engaging with stimulating social media while in bed.

The goal is to make the bedroom a place associated primarily with rest and sleep.

4. Maintain a Consistent Sleep Schedule

A regular sleep-wake schedule can help support healthy sleep habits.

How to Fix Your Sleep Schedule

Allow enough time for sleep: Most adults generally need around 7–9 hours of sleep. Give yourself enough time in bed rather than routinely cutting sleep short.

Keep your wake-up time consistent: Waking at approximately the same time each day can help stabilize your sleep routine.

Leave the bed if you cannot sleep: If you remain awake for a prolonged period, get out of bed and do something calm in low light. Return when you feel sleepy.

Use naps carefully: Long or poorly timed naps may interfere with nighttime sleep in some people with insomnia.

Watch for social jet lag: Social jet lag occurs when your sleep schedule changes substantially between workdays and free days. Large differences between social schedules and your natural circadian rhythm may contribute to sleep difficulties.

Stress Management for Better Sleep

Stress is a common contributor to both short-term and persistent insomnia. Worrying about work, relationships, finances, health, or upcoming responsibilities can keep the brain alert when it should be preparing for sleep.

Developing a relaxing evening routine may help reduce this mental activation.

Mindfulness and Meditation

Mindful breathing and meditation can help create a calmer transition from daytime activity to sleep.

A simple bedtime routine might include:

1. Sit or lie comfortably.
2. Breathe slowly and naturally.
3. Pay attention to the movement of your breathing.
4. When distracting thoughts appear, acknowledge them without dwelling on them.
5. Gradually return your attention to your breathing.

Mindfulness-based approaches may be useful for some people, although individual responses can vary.

Progressive Muscle Relaxation

Progressive muscle relaxation involves deliberately tightening and then relaxing different muscle groups.

The technique can help reduce physical tension and promote relaxation before bedtime.

It may be particularly useful for people whose sleep difficulties are accompanied by muscle tension or stress.

Cognitive Shuffling

Cognitive shuffling is a technique intended to shift attention away from repetitive worrying.

The idea is to think briefly about neutral or pleasant concepts and then move from one unrelated image or thought to another. This may help interrupt repetitive thinking at bedtime.

Evidence for this approach is still developing, so it should be viewed as a relaxation technique rather than a guaranteed treatment.

Try a Gratitude Journal

Writing down a few things you are grateful for before bed may help shift attention away from negative thoughts.

The purpose is not to force positive thinking but to create a calmer mental state before sleep.

Try a “Brain Dump” Before Bed

If your mind becomes busy with unfinished tasks, worries, or tomorrow’s responsibilities, write them down before going to bed.

A simple list can include:

• Tasks you need to complete
• Questions you want to address tomorrow
• Appointments
• Concerns you want to discuss later
• Ideas that keep coming to mind

Creating a specific to-do list before bedtime may help reduce the need to mentally rehearse tasks while trying to fall asleep.

Optimize Your Bedroom for Better Sleep

Your sleeping environment can influence how easily you fall asleep and remain asleep.

Consider the following changes:

• Keep the bedroom comfortably cool.
• Use blackout curtains if outside light is disruptive.
• Consider white noise if environmental sounds frequently wake you.
• Keep the sleeping area comfortable and reasonably uncluttered.
• Choose a mattress that provides appropriate support and comfort.
• Avoid using the bedroom for activities that keep you mentally alert.

Some research has also examined aromatherapy and scents such as lavender for sleep. However, results vary, and more research is needed to determine how consistently aromatherapy benefits insomnia.

Circadian Rhythm and Light Exposure

Your circadian rhythm is the body’s internal timing system that helps regulate sleep and wakefulness.

A region of the brain called the suprachiasmatic nucleus (SCN) helps coordinate this rhythm. Light reaching the eyes provides important signals that help regulate the body clock and influence melatonin production.

Get Natural Light in the Morning

Exposure to natural light in the morning can help reinforce the body’s daily sleep-wake rhythm.

Try spending some time outdoors or near natural daylight earlier in the day when practical.

Reduce Bright Light Before Bed

Bright lighting late at night can make it harder for the body to transition toward sleep.

Consider:

• Dimming household lights during your evening wind-down period.
• Avoiding unnecessarily bright overhead lighting.
• Reducing screen exposure close to bedtime.
• Using night-mode settings on devices when appropriate.

Blue Light and Sleep

Blue-wavelength light from electronic devices can influence melatonin production and may interfere with the body’s preparation for sleep.

Reducing exposure to bright screens in the evening may therefore be helpful for people who are sensitive to nighttime light.

Light Therapy and Circadian Problems

Precisely timed light exposure can be useful for certain circadian rhythm problems, including some situations involving jet lag or shift work.

Because timing is important, people with significant circadian rhythm problems may benefit from discussing light therapy with a healthcare professional.

Food and Drink Habits That Can Affect Sleep

What and when you eat or drink may influence sleep quality.

Foods and Eating Habits That May Disrupt Sleep

Large meals shortly before bedtime can cause discomfort and may interfere with sleep.

Spicy foods may also worsen acid reflux or GERD symptoms in susceptible individuals, potentially disturbing nighttime sleep.

At the same time, going to bed extremely hungry may also make it harder to sleep comfortably.

A balanced approach is to avoid heavy meals close to bedtime while maintaining an appropriate eating routine.

Caffeine, Alcohol, Nicotine, and Evening Fluids

Several substances can interfere with sleep:

• Caffeine: Because caffeine is a stimulant, consuming it late in the day can make falling asleep more difficult.
• Alcohol: Although alcohol may initially make some people feel sleepy, it can disrupt sleep later in the night.
• Nicotine: Nicotine can stimulate the nervous system and interfere with sleep.
• Excessive evening fluids: Drinking large amounts close to bedtime can increase nighttime bathroom trips.

If you experience frequent nighttime awakenings, consider whether your evening intake may be contributing.

Foods That May Support Healthy Sleep

A generally healthy eating pattern may be beneficial for overall sleep and health.

Some foods have been studied in relation to sleep, including:

• Kiwi
• Bananas
• Tart cherries
• Almonds
• Dairy products
• Fruits and vegetables

However, evidence for individual foods remains limited, and these foods should not be considered treatments for insomnia.

Exercise and Physical Activity

Regular physical activity can support overall sleep quality and may help reduce the risk of insomnia.

Activities such as walking, moderate aerobic exercise, stretching, and yoga can also help manage stress and physical tension.

Does Exercise Help Insomnia?

Regular exercise has been associated with improved sleep quality. Moderate physical activity may be particularly useful as part of a healthy lifestyle.

Yoga may also support sleep by combining movement, relaxation, and stress reduction.

Can Exercising at Night Cause Insomnia?

The effect of evening exercise varies between individuals.

Very intense workouts immediately before bedtime may make it harder for some people to fall asleep because of increased alertness and physiological activation.

If late exercise affects your sleep, try moving vigorous workouts earlier in the day.

Sleep Supplements: What Does the Evidence Say?

Many people consider supplements when they have trouble sleeping. Commonly discussed options include:

• Melatonin
• Magnesium
• Valerian
• Chamomile
• L-theanine
• Ashwagandha

However, “natural” does not automatically mean safe or effective for everyone.

Melatonin

Melatonin is a hormone involved in regulating the sleep-wake cycle and is commonly used in sleep-related products.

Research suggests it may help some people, although its effectiveness for insomnia varies.

Possible side effects can include:

• Headache
• Dizziness
• Stomach discomfort

Magnesium

Magnesium is sometimes used as a sleep supplement. Research has explored different magnesium formulations and their possible effects on sleep and cognitive function.

Possible gastrointestinal effects can occur in some people.

Anyone considering magnesium supplementation should take into account their overall health, medications, and dietary intake.

Valerian Root

Valerian is an herbal product commonly marketed for sleep.

Research has not established it as a consistently effective treatment for insomnia, although some studies suggest it may modestly improve people’s perception of sleep quality.

Possible side effects include headache, dizziness, and stomach upset.

Chamomile

Chamomile contains compounds such as apigenin that have been studied for their potential effects on relaxation and sleep.

Some research suggests chamomile may have sleep-supporting effects, but stronger evidence is needed before considering it a reliable insomnia treatment.

Allergic reactions are possible, although uncommon.

L-Theanine

L-theanine is an amino acid found naturally in tea and is also available as a supplement.

Some research has examined its potential role in relaxation and sleep quality. However, evidence is still developing, and supplement use should be individualized.

Ashwagandha

Ashwagandha has also been investigated for its possible effects on stress and sleep.

However, it can cause side effects such as:

• Nausea
• Diarrhea
• Abdominal discomfort
• Vomiting

It may also interact with medications or be unsuitable for certain people.

Important Safety Considerations

Before starting a supplement for insomnia, talk with a healthcare professional, particularly if you:

• Take prescription medications.
• Have a chronic medical condition.
• Are pregnant or breastfeeding.
• Are considering long-term supplementation.
• Have unexplained or persistent sleep problems.

Supplements should not replace evaluation and treatment of an underlying sleep disorder.

Medical Conditions That Can Affect Sleep

Sometimes insomnia is not simply a matter of sleep habits. Another health condition may be contributing to the problem.

Possible contributors include:

Restless Legs Syndrome

Restless legs syndrome can cause uncomfortable sensations and an urge to move the legs, making it difficult to fall or remain asleep.

GERD

Gastroesophageal reflux disease can cause nighttime discomfort and may interfere with sleep in some people.

Allergies and Nasal Congestion

Allergic rhinitis and nasal congestion can make comfortable breathing during sleep more difficult and may contribute to poor sleep.

Obstructive Sleep Apnea

People with obstructive sleep apnea repeatedly stop or reduce breathing during sleep. These events can cause repeated awakenings and significantly disrupt sleep quality.

Loud snoring, witnessed breathing pauses, and excessive daytime sleepiness can be warning signs.

Mental Health Conditions

Anxiety, depression, bipolar disorder, schizophrenia, and other mental health conditions can affect sleep.

The relationship can also work in the opposite direction: persistent insomnia may worsen emotional and mental well-being.

Long COVID and Sleep Problems

Some people experiencing long COVID report disrupted sleep, frequent awakenings, difficulty maintaining sleep, nightmares, or restless-leg symptoms.

Skin Conditions

Conditions such as eczema, atopic dermatitis, and psoriasis can cause itching or discomfort that interrupts sleep. Poor sleep may also make it harder for the body to recover from ongoing physical stress.

Menopause-Related Sleep Problems

Hormonal changes during menopause can contribute to nighttime awakenings, temperature changes, and alterations in sleep patterns.

If menopausal symptoms are significantly affecting sleep, discussing treatment options with a healthcare professional may help.

When Should You See a Doctor About Insomnia?

Consider speaking with a healthcare professional if:

• Sleep problems continue for three months or longer.
• You regularly feel excessively sleepy during the day.
• Loud snoring or breathing pauses occur during sleep.
• Anxiety or depressive symptoms accompany your sleep problems.
• Poor sleep is interfering with work, studies, relationships, or daily activities.
• You regularly depend on sleep medication or supplements.
• You suspect another medical condition is affecting your sleep.

Persistent insomnia may require more than lifestyle changes. A healthcare professional can help determine whether an underlying sleep, medical, or mental health condition needs treatment.

Frequently Asked Questions About Insomnia

How Can I Manage Insomnia During the First Trimester of Pregnancy?

During early pregnancy, maintaining a regular sleep schedule, reducing screen exposure before bedtime, and limiting caffeine later in the day may support better sleep.

Pregnancy-related sleep problems can have multiple causes, so persistent or severe insomnia should be discussed with a healthcare professional.

Is There a Connection Between Diabetes and Insomnia?

Yes. Diabetes and sleep can influence one another.

People with type 2 diabetes may be more likely to experience sleep problems, particularly when other health conditions are present. In turn, poor sleep may make blood glucose management more difficult.

Maintaining a regular sleep-wake routine and getting adequate sleep can be part of a healthy diabetes-management strategy.

Can a Sleep Tracker Cause Insomnia?

In some people, excessive attention to sleep-tracker data may increase anxiety about sleep.

This phenomenon is sometimes called orthosomnia. A person may repeatedly check their sleep score and become worried about not achieving an “ideal” amount of sleep.

Sleep trackers can provide useful information, but they should not become a source of bedtime stress.

Can Knowing Your Chronotype Help With Insomnia?

A chronotype describes a person’s natural tendency toward earlier or later sleep and wake times.

Understanding your chronotype may help explain why certain schedules feel easier or more difficult. When possible, maintaining a routine that is compatible with your natural sleep timing may reduce circadian disruption.

Can Sleeping Pills Cause Insomnia?

Some prescription sleep medicines can provide short-term relief, but medication should be used under appropriate medical supervision.

Certain sedative medications can cause dependence when used for extended periods. Long-term sleep problems should therefore be evaluated rather than managed indefinitely through medication alone.

Never stop a prescribed sleep medication suddenly without speaking with your healthcare professional.

What Is the 10-3-2-1-0 Sleep Method?

The 10-3-2-1-0 method is a popular sleep routine based on several time-based habits:

• 10 hours: Avoid caffeine for approximately 10 hours before bed.
• 3 hours: Avoid food and alcohol close to bedtime.
• 2 hours: Stop work or mentally demanding tasks.
• 1 hour: Avoid screens.
• 0: Avoid repeatedly using the snooze button in the morning.

Although the method is popular online, there is not enough specific scientific evidence to establish that the complete 10-3-2-1-0 system itself treats insomnia.

What Is the 30-30 Rule for Insomnia?

The 30-30 approach is associated with Brief Behavioral Treatment for Insomnia (BBTI), a shorter behavioral approach related to CBT-I.

One principle is to avoid remaining awake in bed for prolonged periods. If you have been awake for around 30 minutes, getting out of bed and returning when sleepy may help prevent the bed from becoming associated with wakefulness.

Behavioral insomnia treatments can be individualized, so professional guidance may be useful.

What Deficiencies Are Associated With Sleep Problems?

Some nutritional deficiencies have been associated with sleep-related problems. Iron and vitamin D are among the nutrients that have been studied in relation to sleep.

However, insomnia should not automatically be attributed to a nutrient deficiency. Testing and supplementation should be based on individual circumstances and medical advice.

Is There a Best Sleeping Position for Insomnia?

There is no single sleeping position proven to be best specifically for insomnia.

However, sleeping position can influence other conditions that affect sleep. For example, side sleeping may help some people with snoring or mild sleep apnea, while certain positions may worsen symptoms of reflux or musculoskeletal discomfort.

Choose a comfortable position and discuss persistent symptoms with a healthcare professional.

Final Thoughts

Better sleep often starts with consistent daily habits rather than a single quick fix. Maintaining a regular sleep schedule, reducing stimulating screen use before bedtime, managing stress, getting appropriate physical activity, optimizing the bedroom, and using light strategically can all support healthier sleep.

For persistent insomnia, Cognitive Behavioral Therapy for Insomnia (CBT-I) is an important evidence-based treatment approach. Supplements such as melatonin, magnesium, valerian, chamomile, and other products may be considered in some circumstances, but their benefits and risks vary.

Most importantly, ongoing insomnia should not simply be ignored. Sleep difficulties may sometimes be a symptom of another medical, mental health, or sleep-related condition. If poor sleep continues or starts affecting daytime functioning, consult a qualified healthcare professional for an appropriate evaluation.
