Insomnia is a very common disorder, characterized by the inability to fall asleep even when it's time to rest. This problem can be attributed to different causes, like hormonal changes, a busy schedule, environmental noise, and odd behavior of some neurons in the brain that are supposed to "switch off" the signals that keep you awake. Although the main cause of sleep disorders is still largely unknown, serotonin, epinephrine, melatonin, and tryptophan have all been associated with the state of alertness of the brain.
As caffeine and other stimulants cannot overcome the effects of severe sleep deprivation, and those hours can't be recovered, there are natural and delicious alternatives that can help to regulate brain chemistry so that you can finally get some rest.
Among passion fruit's varied medicinal properties and benefits, its harmane content is believed to trigger the release of gamma-aminobutyric acid (GABA), an amino acid that acts as a neurotransmitter in the central nervous system, inducing a state of tranquility and relaxation that leads to a good night of sleep. Drinking some passion fruit juice may help you finally get that much-needed rest.
According to some studies, the antioxidants and serotonin contained in kiwi may have some positive influence on brain chemistry, improving sleep onset, duration, and quality in people who suffer from sleep disorders. Consuming a couple of kiwis at night during a span of four weeks has been shown to help reduce sleep disorders.
Bananas have a powerful combination of magnesium, vitamin B6, and natural complex carbs that promote the production of serotonin, an important neurotransmitter that controls sleep cycles. They are also a great source of tryptophan, an amino acid that induces drowsiness by stimulating serotonin production. Eating bananas on a regular basis can help normalize sleep patterns.
Avenanthramides, polyphenols in oats, have shown strong antioxidant and anti-inflammatory activity. However, oats also produce melatonin, which promotes growth in plants and animals, and is arguably linked to sleep cycles. Although melatonin hasn't been exhaustively studied, it is well-known as the "hormone of darkness" due to the increase in its levels during the night and its influence on the circadian rhythm of most species, including humans. Having a good bowl of oats and bananas before going to bed can make a big difference in the quality of your sleep.
The human body is typically in a state of alertness during the day and goes into a resting cycle during the night. The amount of sleep you need depends on many variables, but generally, seven to eight hours a night seems to be enough for most adults; less than that can cause sleep deprivation. Whatever the reason that keeps you awake, there is always a natural way to regain that necessary balance. Give it a try and have a good night!
