我们使用数百万条公共推特消息中的数据，确定了全球不同文化中的个人水平的昼夜和季节性情绪节律。我们发现，人们醒来时心情很好，随着时间的推移而恶化--这与睡眠和昼夜节律的影响一致--而且基线积极情绪的季节性变化会随着白天长度的变化而变化。人们在周末更快乐，但积极情绪的早晨高峰期推迟了2小时，这表明人们在周末醒得更晚。
We identified individual-level diurnal and seasonal mood rhythms in cultures across the globe, using data from millions of public Twitter messages. We found that individuals awaken in a good mood that deteriorates as the day progresses-which is consistent with the effects of sleep and circadian rhythm-and that seasonal change in baseline positive affect varies with change in daylength. People are happier on weekends, but the morning peak in positive affect is delayed by 2 hours, which suggests that people awaken later on weekends.
