Based upon Brain function booster existing literature, wakefhlness is no wakefulness and diet that certain wkefulness of food have waefulness measurable effect wakefulness and diet sleep, either subjectively wakeffulness assessed by validated questionnaires or objectively when measured via polysomnography or wearable devices. Yamada, T. Nutrients 8E Research has found that people who stick to a Mediterranean diet are more likely to have adequate sleep quality. Restricted feeding uncouples circadian oscillators in peripheral tissues from the central pacemaker in the suprachiasmatic nucleus.

Wakefulness and diet -

experience insomnia, which refers to trouble falling asleep, staying asleep, or getting good quality sleep. According to the National Heart, Lung, and Blood Institute , insomnia can hinder concentration and memory in the short term.

In the long term, it can increase the risk of high blood pressure, heart disease, diabetes, and cancer. While other health conditions and lifestyle factors can lead to insomnia and difficulty sleeping, the food a person eats can also strongly influence sleep quality.

Keep reading to learn more about some foods that can negatively affect sleep quality and keep people awake. Caffeine is a drug that stimulates the central nervous system. Many people consume caffeine, for example, in the form of coffee, to help them wake up in the morning.

Caffeine is also present in chocolate, tea, energy drinks, and soda, such as cola. A systematic review combined evidence from several clinical trials and found that caffeine prolongs the time it takes to fall asleep, reduces total sleep time, and worsens sleep quality.

Additionally, the substance increases wakefulness and arousals. Although some studies have shown health benefits from moderate doses of caffeine, the Food and Drug Administration FDA has recommended that healthy adults limit their consumption to less than milligrams mg per day , the equivalent of 4—5 cups of coffee.

Consuming caffeine in excess can cause nausea, dizziness, dehydration, headaches, restlessness, rapid heartbeat, insomnia, and anxiety. Additionally, the Centers for Disease Control and Prevention CDC recommend that people with insomnia avoid caffeine.

Although alcohol is a depressant, it does not promote restful sleep. Although some people may fall asleep quickly after consuming alcohol, they often find themselves waking up earlier than usual and struggling to go back to sleep. Alcohol also interferes with the circadian rhythm, worsening sleep quality.

It can also negatively affect sleep apnea. A review of studies in healthy adults confirmed the negative effects of alcohol on sleep. It found that although alcohol may reduce the time a person needs to fall asleep, it significantly disrupts rapid eye movement REM sleep, particularly in the second half of sleep.

People require quality REM sleep for sufficient rest. A study of medical students reports that spicy foods may negatively affect sleep in several ways. They can cause indigestion, acid reflux, and heartburn, making it uncomfortable to lie down.

Additionally, acid reflux can worsen sleep apnea. These foods also raise body temperature, making it difficult to get cool enough to fall asleep comfortably. The tolerance for heat from chili peppers, within in many spicy foods, and its effects on the body, varies from individual to individual.

For those people who find that consuming spicy foods negatively affects sleep, it may be best to avoid eating them in the hours before bedtime. Foods that cause a spike in blood sugar, such as white rice, potatoes, candy, and other sugary foods, are called high glycemic GI foods.

Consuming these foods causes blood sugar to rise rapidly, resulting in the release of insulin, which affects tryptophan and serotonin levels. There is also a complex interaction of insulin with adrenalin, cortisol, glucagon, and growth hormone, all of which can negatively impact sleep.

Research seems to indicate that eating too many of these foods can contribute to insomnia. It can also increase inflammation in the body and alter intestinal bacteria. Eating too many of these foods can also increase inflammation in the body and alter gut bacteria. Additionally, a large study found a link between intake of high GI foods and insomnia in postmenopausal women across a 3-year period.

Consuming high fat content foods, such as fatty meats and desserts, may also disrupt sleep. Fatty foods will cause the stomach to feel full and may make it difficult for individuals to feel comfortable.

They can also cause indigestion and acid reflux, which are also likely to result in poor sleep quality. In a study of medical students , higher fat intake had links to shorter total sleep time, less restorative sleep, and more sleep disruption.

Another smaller study in 26 healthy adults also found that consuming a diet high in saturated fat had associations with lighter, less restorative sleep. However, a much larger cohort study in men found an association between higher levels of trans fats and probable insomnia. A review of epidemiological studies found similar results.

Highly processed foods include fast food and prepackaged foods. While convenient, these foods contain many of the nutritional components above, including sugars and fats, which negatively impact sleep.

In a study of approximately 2, young adults, researchers found that higher consumption of processed foods shares significant links with poor sleep quality. Additionally, research found that highly processed foods cause shorter durations of sleep and poor sleep quality in children aged 12—18 years.

Knowledge in this field has substantially increased over the past 10 years and the importance of sleep is increasingly recognized in public health strategies and clinical practice , However, key knowledge gaps remain and future studies are needed to address these gaps and move the agenda forward Box 3.

Sleep and circadian rhythms are critical for optimal metabolic and weight regulation and directly influence eating and activity behaviours to impact health.

Future efforts should aim to quantify the global burden of disease associated with poor sleep health and circadian health for example, health-care and productivity costs and test the cost-effectiveness of interventions at the population level.

Sleep and circadian health are important pillars of health and are part of an overall healthy lifestyle along with a healthy diet and physical activity.

Large trials with long follow-ups are needed to determine whether the short-term effects of sleep restriction and circadian disruption on metabolic health and obesity last over time. Furthermore, studies are needed to determine whether there are differences between acute and chronic insufficient sleep and circadian disruption.

Research in this area is limited by safety concerns; thus, designs are mostly limited to observational studies. The interaction between sleep, circadian clocks and gut hormones and how these factors modulate appetite and metabolism as well as their clinical relevance for the efficacy of novel pharmacotherapies for obesity should be examined.

The timing of food intake as it relates to the sleep schedule and circadian timing as well as its influence on altering metabolic health and obesity should be examined. Studies are needed to examine how the different sleep health characteristics, combined and individually, affect metabolic health and obesity.

Research is needed to determine whether energy intake is promoted under conditions of circadian misalignment and ad libitum food intake. Studies are needed to examine the most effective circadian times for exercising and how much exercise is needed for shift workers to maintain their metabolic health.

Studies should examine whether obesity, independent of sleep disorders, causes poor sleep and should identify the underlying mechanisms. Additional investigations are needed into how diet content and quality affect circadian rhythmicity and sleep health.
