According to traditional medicine, longan is used to support the treatment of nervousness and insomnia due to lack of qi and blood. The dried longan flesh has the effect of soothing, helping to relax the spirit, especially suitable for people who are sleepless due to thinking too much, leading to heart failure.
Longan contains amino acids and trace elements that can affect neurotransmitters in the brain. Some active ingredients help reduce mild anxiety, create a feeling of relaxation, thereby supporting sleep. This is also the reason why many people feel sleepy after eating longan.
When combined with longan and lotus seeds, the sedative effect can be enhanced. However, it is necessary to use in moderation, about 5 longans and 10 lotus seeds are suitable; using too much can cause dry mouth. The best time is to eat about 2 hours before bedtime for the body to have time to absorb.
Another way to use it is to cut longan meat into small pieces and put it in warm milk. Tryptophan in milk combined with longan ingredients creates a synergistic effect, helping to fall asleep more easily. Note that milk should only be at a moderately warm level because too high a temperature can reduce beneficial nutrients. This combination is usually more effective than eating longan individually.
However, you should not eat too much longan after 8 pm, as high sugar content can cause blood sugar fluctuations. For people with slow metabolism, this can even cause them to wake up in the middle of the night, reducing sleep quality.
