Grapes, bananas, kiwi fruit, strawberries, lychee

Recently, a study has confirmed that grapes are good for improving insomnia. The reason for this is that grapes contain melatonin, a substance that aids sleep. Melatonin is a substance secreted by the pineal gland in the brain, and there is a close relationship between it and sleep. The night is a period of strong melatonin secretion, signaling the impending sleep, and the morning is the time when melatonin secretion is at its lowest, which means it is time to sleep and wake up. Therefore, it can help regulate the sleep cycle, so that abnormal sleep conditions can be improved. Experts also say that the melatonin content in wine may be a little higher due to the antioxidants and alcohol it contains, which is more helpful for sleep.

Bananas contain vitamin B6, which keeps people away from depression, and 5-hydroxytryptophan, a substance that makes people happy, as well as a large amount of potassium, which has a health effect on the human body and can effectively keep people away from the symptoms of depression and promote sleep.

A recent study shows that consuming two kiwi fruits a day can improve sleep quality by forty percent! Sleep disorders are related to excessive arousal of the central nervous system, sympathetic nervous system or stress that leads to hormonal secretion. Kiwi fruit is rich in calcium, magnesium and vitamin C, which helps the synthesis and transmission of neurotransmitters, in addition, it also contains other fruits in the rare calcium, with mood stabilization and inhibit the role of the sympathetic nervous system.

The food with more mineral elements has a calming effect on the mind, and the strawberry, which is regarded as the holy fruit of beauty by women, also contains a high amount of potassium and magnesium which are two kinds of trace elements, which can effectively relieve the nervous tension, stabilize the mood, and have a hypnotic effect.

As lychee is rich in glucose, sucrose, vitamin A, vitamin B, vitamin C, as well as citric acid, folic acid, malic acid and free amino acids, and thus has a very good therapeutic effect on the treatment of overthinking, forgetfulness and insomnia.
