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.

这项研究的目的是研究色氨酸摄入量和光暴露对睡眠和褪黑激素分泌的影响，通过在白天进行早餐和光暴露时修饰色氨酸摄入，并在晚上测量睡眠质量和褪黑激素分泌。 33名男大学生完成了持续5天4晚的实验。将受试者随机分为4组：早晨的色氨酸贫困早餐（55mg/餐），白天昏暗的环境（<50lx），富含色氨酸的早餐（476毫克/餐）以及昏暗的淡淡，淡淡的淡淡，畅通无阻的早餐和鲜艳的早餐和明亮的浅色（> 5000lx），富有色彩的早餐和亮点。第四天的唾液褪黑激素浓度明显低于第一天的贫困*，而在第四天，在Rich*Bright的第四天较高。结果表明，在白天，富含色氨酸的早餐和明亮的光线曝光的结合可以在晚上促进褪黑激素的分泌。
