Understanding the Relationship Between Eating Habits and Insomnia

Insomnia is a condition with causes that vary from person to person and can be a result of stress, caffeine, and excessive screen time. Can modifying eating habits help reduce episodes and improve sleep patterns?

Eating Habits and Insomnia

Insomnia is a common sleep disorder characterized by persistent difficulty falling asleep, staying asleep, and/or both. Individuals often experience daytime sleepiness, mood disturbances, or cognitive impairments. There are two types:

  • Primary insomnia, which is not linked to other health conditions.
  • Secondary insomnia is associated with other health issues like asthma, depression, or heartburn. (National Library of Medicine, 2024)

While there are various causes of insomnia, researchers have recently learned more about its impact on eating habits. New data has found that an individual’s dietary pattern may impact sleep habits. (Gan Z. H. et al., 2024)

Risk Factors

Chronic insomnia is linked to negative health outcomes, including an increased risk of high blood pressure, diabetes, obesity, depression, heart attack, and stroke. (Chalet F. X. et al., 2023) (Marie-Pierre St-Onge et al., 2016) Researchers recruited over five thousand participants who did not have insomnia and evaluated their eating habits and insomnia incidence. (Gan Z. H. et al., 2024) Results showed that 464 of the participants developed insomnia, and of those, the risk was lower in vegetarians than those who ate more meat. Males who followed a more plant-based diet had a reduced incidence of insomnia; however, this relationship was not seen among females. The research suggests that a diet with more vegetables may positively affect sleep. Many plant-based foods are rich sources of sleep-supporting compounds, such as melatonin. Treating and preventing insomnia is important for restoring health and daily functioning.

Past nutritional data highlights the relationship between healthy sleep and a diet rich in fruits, vegetables, legumes, and other sources of tryptophan and melatonin. (Zuraikat F. M. et al., 2021) Prior research also shows how vegetarian diets can help reduce chronic inflammation, positively impacting sleep. (Dzierzewski J. M. et al., 2020) Specifically, the Mediterranean diet, known for its anti-inflammatory effects, is linked to improved sleep and reduced insomnia. (Zaidalkilani A. T. et al., 2021) Also, data links a vegetarian diet to improved mood, which might enhance the quality of sleep by moderating mental health, including depression condition. (Wang X. et al., 2023)

Support Quality Sleep

According to dieticians, looking at an individual’s eating habits during the day is crucial in determining why they can’t sleep at night. Often, making a few small dietary adjustments is enough to help with better sleep. Some steps to try include:

  • Increase magnesium by adding more leafy greens, nuts, and seeds.
  • Incorporating melatonin-rich foods like walnuts rather than relying on melatonin supplements.
  • Easing off caffeine, alcohol, and refined carbohydrates can help improve sleep quality.

Dietary changes should not be the only way to combat insomnia. Cognitive behavioral therapy (CBT-I) is a recommended first-line treatment rather than sleeping medications, along with learning healthy sleep habits and using the right mattress. This therapy can help improve sleep habits and behaviors by rethinking sleep and current practices that could affect an individual’s ability to sleep well. Combining CBT-I with a healthy diet and regular physical activity can significantly impact overall health and sleep patterns.

Say Goodbye to Insomnia & Start Enjoying Quality Sleep

Can individuals with insomnia find various ways to reduce its effects, such as a full night’s rest and promoting healthy sleep habits?

Insomnia

Many people have often struggled to get a full night’s sleep occasionally, as environmental factors can keep them from falling asleep, making them tired throughout the day. In most cases, many individuals sometimes suffer from a chronic condition known as insomnia. Insomnia is a common sleep disorder, whether short-term or chronic, and it can negatively impact a person’s ability to sleep and stay asleep. (Dopheide, 2020) Insomnia can be in two forms: primary and secondary. Primary insomnia is a fairly common condition that can be resolved without treatment, while secondary insomnia is due to medication side effects or neurological issues that are causing sleep issues. Additionally, insomnia can be developed through various environmental factors like genetic variants, early life stress, major life events, and brain functions and structures that can cause individuals to be vulnerable and have insomnia. (Van Someren, 2021) We associate with certified medical providers who inform our patients of the effects of insomnia that can affect the body when they are not getting enough sleep. While asking important questions to our associated medical providers, we advise patients to incorporate healthy sleeping habits into their treatment plan to reduce insomnia and get proper sleep. Dr. Alex Jimenez, D.C., envisions this information as an academic service.

How It Affects The Body

So, how does insomnia affect the body and a person’s daily routine? Well, when environmental factors start to impact a person, it can cause overlapping risk profiles in the body that can develop into mental disorders like depression. There is a bi-directional relationship between insomnia and depression, as it can cause sleep alterations that can affect the nervous system and develop into chronic conditions. (Riemann et al., 2020) Some of the symptoms that insomnia can affect the body include: (Naha et al., 2024)

  • Fatigue
  • Memory impairment
  • Cardiovascular disorders
  • Gastrointestinal disorders
  • PTSD
  • Daytime napping

However, there are ways to manage insomnia and reduce the co-morbidities.

Ways To Manage Insomnia

When managing and treating insomnia, many people must recognize the many environmental factors that can lead to its development. Since insomnia is linked with environmental factors, many people start making small routine changes to mitigate its effects. Many people can start by identifying the disorder and other co-morbidities contributing to its development. (Waterman & Selsick, 2023) This, in turn, helps doctors develop a customized treatment plan to manage their insomnia.

Sleep Habits

One of the ways many people deal with insomnia can begin with changing their sleep habits to help reduce the environmental factors affecting their sleep quality. Some of the changes include:

  • Sleeping on a comfortable mattress
  • Reduce screen time by an hour before bed
  • Maintain a regular sleep and waking schedule
  • Make sure the bedroom is dark, cool, and has minimal noise

Incorporating these small changes in sleeping habits can help reduce the stressors contributing to insomnia.

Non-Surgical Treatments

Another way for individuals to manage their insomnia is by incorporating non-surgical treatments. Non-surgical treatments like mindfulness meditation, chiropractic care, and acupuncture can help many individuals calm the mind and body by combining deep breathing exercises. (Chan et al., 2021) At the same time, the body and muscles can begin to relax and even help stretch out tense muscles that are affected by insomnia. Many people can utilize non-surgical treatments as part of their routine to live healthy lives and have the best quality of sleep they deserve.

Primary Insomnia Explained: Symptoms and Solutions

Could learning to apply healthy sleep hygiene habits help improve sleep and overall health for individuals with sleeping difficulties?

Primary Insomnia

Insomnia affects most adults at some point in their lives. Primary insomnia is a fairly common condition characterized by difficulty sleeping, and sometimes, it can resolve without treatment. A diagnosis of primary insomnia means that there is no need to worry that a medical or psychological issue is causing sleep problems. Secondary insomnia is the result of medication side effects or medical or psychological issues. However, individuals may need a diagnostic evaluation, including blood tests or an overnight sleep study, to determine an underlying cause for persistent insomnia. Managing lifestyle habits is usually effective for the relief of primary insomnia. If that doesn’t work, medical treatment may be recommended.

Symptoms

Primary insomnia means not getting enough sleep. Individuals with primary insomnia average six hours of sleep per night (Flynn-Evans E. E. et al., 2017). They often toss and turn or get out of bed frequently. Typically, primary insomnia makes it hard to fall asleep and/or stay asleep. Individuals can wake up easily by triggers like noises or even without triggers. Sleep deprivation can lead to several health problems when awake. Symptoms of insomnia fatigue include: (Salisbury-Afshar E. 2018)

  • Trouble waking up in the morning
  • Constant yawning
  • Feeling tired and sleepy throughout the day
  • Lack of energy for physical activity
  • Lack of motivation
  • Hunger
  • Difficulty concentrating
  • Irritability
  • Headaches
  • Hypersomnia or falling asleep during the day
  • Sensitivity to noise or lights when awake
  • Bouts of hyperactivity
  • Jumpiness
  • Being easily alarmed or frightened

Individuals can experience these symptoms for a few days in a row and resolve the day after a restful night of sleep or after a nap. There are times when fatigue can help with falling asleep, which helps to resolve insomnia.

Complications

Individuals can develop severe anxiety and distress about the fact that they are not getting enough sleep. This anxiety is usually more severe before going to bed or in the middle of the night, but the worry can continue during the day as well. Persistent insomnia and chronic lack of sleep can lead to depression and predispose the mind and body to health complications. (Sun, Q., & Tan, L. 2019) Insufficient sleep is associated with lowered immune system function, obesity, and heart disease. (Hung C. M. et al., 2018)

Causes

The conundrum of primary insomnia is that it does not have an identifiable cause, but certain risk factors predispose individuals to have primary insomnia. The condition persists throughout a person’s life, often worsening or improving for months or years. Primary insomnia can be more common among those who have family members with insomnia. Research has found that, while primary insomnia isn’t caused by psychiatric issues, tending to stress or a worry-prone personality might be predisposing factors. (Hung C. M. et al., 2018)

Circadian Rhythm

Research has found that primary insomnia is associated with circadian rhythm irregularities. Primary insomnia can result from individuals falling into deeper sleep phases earlier than those who don’t have the condition. (Flynn-Evans E. E. et al., 2017) However, it can be challenging to know whether early deep sleep is a cause or an effect of primary insomnia. This is because sleep deprivation can also lead to deep sleep’s abrupt or rapid onset.

Diagnosis

Getting enough sleep is a common concern throughout life. Diagnosing primary insomnia involves various steps. One of the main components of identifying insomnia is determining whether the individual needs more sleep than they are getting. For individuals who are unable to get the proper amount of sleep, the second aspect of primary insomnia diagnosis is focused on finding the reason for their lack of sleep. Diagnostic tests measure insomnia and its effects and include:

Sleep Study

  • A polysomnogram is an overnight sleep study measuring brain activity, muscle activity, and breathing.
  • The polysomnogram is expected to show decreased sleep and normal breathing patterns if it is primary insomnia. (Sun, Q., & Tan, L. 2019)

Pittsburgh Sleep Quality Index 

  • The PSQI is a questionnaire that includes a self-assessment of sleep.
  • It helps identify sleep patterns and issues like using the bathroom frequently at night.

Multiple Sleep Latency Test

  • An MSLT is a daytime nap study in which participants are monitored to determine how fast they fall asleep.
  • The test results are a reflection of your sleep deprivation.

These studies help assess whether an individual is not getting enough sleep and what type of sleep interruption is experienced. Other tests might include screening questionnaires or other assessments of emotional issues like depression and anxiety. Sometimes, individuals are aware of these problems but may dismiss symptoms of depression and anxiety, and they instead manifest as insomnia.

Ruling Out Underlying Causes

Medical causes of insomnia can include: (Guo H. M. et al., 2017)

  • Thyroid disease
  • Liver disease
  • Dementia
  • Restless leg syndrome
  • Breathing problems. 

Individuals might need to have tests to determine whether any of these underlying issues are contributing to their insomnia. Individual medical symptoms and physical examination would guide the diagnostic testing.

Sleep Hygiene Habits

Individuals can start making small lifestyle adjustments to help regulate their sleep. The key is to avoid things that prevent falling asleep when you want to. Healthy habits include:

  • Avoid caffeine in the afternoon or evening.
  • Avoid alcohol.
  • Avoid napping during the day.
  • Don’t turn on a phone, computer, or television screen in the bedroom before going to bed.
  • Staying away from bright lights for several hours before sleep.
  • Scheduling tasks so you feel caught up before going to sleep.
  • Getting enough to eat so you aren’t hungry before going to bed.
  • Not eating so much that you feel bloated before going to bed.
  • Doing some light exercise several hours before going to bed.

Medical Treatment

If lifestyle habits don’t help alleviate insomnia, talk to a healthcare provider about medical therapy. Some notice a benefit from treatment with non-prescription-based strategies like counseling, cognitive behavioral therapy for insomnia (CBT-I), or acupuncture. These approaches can have a longer-lasting effect without the risk of side effects. (Salisbury-Afshar E. 2018) A healthcare provider might recommend melatonin or may prescribe medication such as antidepressants, antihistamines, or benzodiazepines.

Injury Medical Chiropractic and Functional Medicine Clinic

Navigating insomnia can be challenging, but understanding the treatment process can significantly help the individual. A healthcare provider can determine the most effective treatment strategies. This can include physical therapy, rest, health coaching, and medication. Overcoming these limitations is possible.
