Introduction
In general, consuming lychee has limited effects on improving insomnia, and excessive consumption may even be detrimental to sleep. In daily life, to alleviate insomnia, one should develop regular sleep habits, avoid overeating, and refrain from consuming stimulating beverages before bedtime. It may be beneficial to eat foods that help relax the nerves, such as bananas and milk, while maintaining a quiet and comfortable sleep environment.

Generally speaking, consuming lychee has limited effects on improving insomnia, and excessive consumption may even be detrimental to sleep. The detailed analysis is as follows:

Lychee contains sugars, vitamins, and other nutrients. Moderate consumption can help replenish energy and relieve fatigue, possibly offering slight auxiliary benefits for short-term insomnia caused by mild fatigue or insufficient energy. However, lychee does not contain any components that directly promote sleep and therefore cannot fundamentally resolve insomnia issues.

Excessive consumption of lychee may lead to blood sugar fluctuations due to its high sugar content. It may also cause gastrointestinal discomfort due to increased digestive burden, thereby affecting sleep quality. Particularly when consumed in large quantities before bedtime, it may make it harder to fall asleep due to physical discomfort.

In daily life, to improve insomnia, it is advisable to develop regular sleep habits and avoid consuming large amounts of food or stimulatory beverages before bedtime. One may also consume foods that help relax the nervous system, such as bananas or milk, and maintain a quiet and comfortable sleeping environment to improve sleep quality.
