Regulate sleep
Due to the modest levels of melatonin they contain, walnuts can enhance the quality of your sleep. The hormone melatonin is in charge of producing the wakefulness-related pigment melanin. Melatonin particularly regulates your daily cycles of wakefulness and sleep. Melatonin, which is included in walnuts, may help you sleep better. Melatonin levels in walnuts range from 2.5 grams to 4.5 nanograms.
Melatonin, a hormone that aids in inducing and regulating sleep, is produced by this nut. These nuts contain melatonin in a bio-available form. Laboratory rats given walnuts had higher blood melatonin concentrations than those fed a controlled diet without the nuts, according to a study published in the journal Nutrition in 2005. So, to promote a sound, peaceful night's sleep, it's ideal to include walnuts in your supper dishes.
