Melatonin is a natural hormone that plays an important role in sleep. Foods like pistachios, tart cherries, mushrooms, and tomatoes are good sources of melatonin.
Foods like kale, broccoli, chicken, nuts and whole grains are rich in tryptophan, magnesium, calcium and other nutrients essential to helping your body regulate sleep, says Kelly M. Rubenstein, a registered dietitian with the UCI Health Weight Management Program.
Eggs and fish are higher melatonin-containing food groups in animal foods, whereas in plant foods, nuts are with the highest content of melatonin. Some kinds of mushrooms, cereals and germinated legumes or seeds are also good dietary sources of melatonin.
Broccoli : Broccoli is beneficial for health. But don't make the mistake of eating at dinner. The fiber present in broccoli takes longer to digest, which can disrupt sleep at night. Apart from this, gas or acidity problems may also occur in the morning.
Dim your lights at night
Bright lights at night can confuse and disrupt our internal body clock as melatonin increases with darkness and decreases with light. A simple yet effective way to increase melatonin production, to help you sleep, is to dim your lights at least one hour before bedtime.
Melatonin secretion decreases during aging. Reduced melatonin levels are also observed in various diseases, such as types of dementia, some mood disorders, severe pain, cancer, and diabetes type 2. Melatonin dysfunction is frequently related to deviations in amplitudes, phasing, and coupling of circadian rhythms.
Cherries (especially sour cherries like the Montmorency variety) are one of the only (and highest) natural food sources of melatonin. Studies have shown a boost in circulating melatonin after consumption of cherries, though sweet cherries have half the melatonin content as sour cherries.
Leafy greens are good for all sorts of things, but they're also a powerful sleep aid. Lettuce, in particular, contains high levels of lactucarium. Commonly called “lettuce opium,” this powerful substance is a sedative that helps promote feelings of relaxation and sleepiness.
Blueberries Improve Memory, Sleep Quality, and Mood
They're also an excellent source of melatonin—the hormone that helps you sleep.
Melatonin is a natural hormone that's mainly produced by your pineal gland in your brain. It plays a role in managing your sleep-wake cycle and circadian rhythm. Scientists still have a lot to learn about all of its effects on the human body.
The synthesis and release of melatonin are stimulated by darkness, melatonin is the "chemical expression of darkness" and inhibited by light [4]. Photic information from the retina is transmitted to the pineal gland through the suprachiasmatic nucleus of the hypothalamus (SCN) and the sympathetic nervous system [5].
According to one study, kiwis have shown to improve sleep quality and may be one of the best foods to eat before bed. In a 4-week study, 24 adults ate 2 Zespri® Green Kiwifruit one hour before bed every night. Results indicated the adults fell asleep 42% quicker and stayed asleep 13% longer.
In humans and most diurnal mammals, melatonin is secreted at night with a robust circadian rhythm and maximum plasma levels that occur around 3 to 4 AM. The daily rise of melatonin secretion correlates with a subsequent increase in sleep propensity about 2 hours before the person's regular bedtime.
In the UK and most of Europe, it's classed as a medicine, not a health supplement and as such, requires a prescription. This is because melatonin is considered “medical by function” which means that it requires a drug licence.
Melatonin levels decline gradually over the life-span and may be related to lowered sleep efficacy, very often associated with advancing age, as well as to deterioration of many circadian rhythms. Melatonin exhibits immunomodulatory properties, and a remodeling of immune system function is an integral part of aging.
According to Lauren Popeck, RD, a dietitian at Orlando Health, Greek yogurt is perfect for bedtime, because it contains the sleep-inducing chemical tryptophan. And because it's such a rich source of protein, Greek yogurt can also help you avoid that same glucose spike.
