项目摘要

The purpose of this study is to investigate effects of tryptophan intake and light exposure on sleep and melatonin secretion, by modifying tryptophan ingestion at breakfast and light exposure during the daytime, and measuring sleep quality and melatonin secretion at night. Thirty three of male University students completed the experiments lasting 5 days and 4 nights. The subjects were randomly divided into 4 groups: tryptophan-poor breakfast (55mg/meal) in the morning and dim light environment (<50lx) during daytime, tryptophan-rich breakfast (476mg/meal) and dim light, tryptophan-poor breakfast and bright light (>5000lx), tryptophan-rich breakfast and bright light. Saliva melatonin concentrations on the fourth day was significantly lower than on the first day in Poor*Dim, whereas it was higher on the fourth day in Rich*Bright. The result indicates that the combination of a tryptophan-rich breakfast and bright light exposure during daytime could promote melatonin secretion at night.

本研究的目的是通过改变早餐时的色氨酸摄入量和白天的光照量，并测量夜间的睡眠质量和褪黑激素分泌量，研究色氨酸摄入量和光照量对睡眠和褪黑激素分泌的影响。 33名男大学生完成了历时5天4夜的实验。受试者被随机分为4组：早上和白天昏暗光线环境（<50lx）时色氨酸含量低的早餐（55mg/餐），光线昏暗时富含色氨酸的早餐（476mg/餐），以及光线昏暗时色氨酸含量低的早餐。明亮的光线（>5000lx）、富含色氨酸的早餐和明亮的光线。在“Poor*Dim”中，第四天的唾液褪黑激素浓度显着低于第一天，而在“Rich*Bright”中，第四天的唾液褪黑素浓度较高。结果表明，富含色氨酸的早餐和白天的强光照射相结合可以促进夜间褪黑激素的分泌。
