This study was conducted to clarify the relationship between sleep disorders and frequency, or timing of dairy intake with 192 university students in Japan. Pearson’s chi-squared test was carried out to find the relationship between two groups of sleep disorders and the timing of dairy product intake (p = 0.034, df = 4, χ2 = 10.38). The sleep disorder occurred significantly less if participants took a dairy product in the morning (p = 0.004) and significantly more when participants took a dairy product in the afternoon (p = 0.028). The findings showed that consuming dairy products in the morning is effective in treating sleep disorders.
