一项伦敦研究发现，人们在早晨最快乐，午夜最忧郁。周日早晨幸福感最高，因为周六可以放松和购物，而季节、天气和社会因素也会影响积极情绪。
A study says people are happiest in the mornings, and bluest at midnight. Researchers in London conducted a study on people's mental well-being at different times of the day. They asked people to rate their feelings of happiness, overall satisfaction with life, and how worthwhile they thought life was. The researchers said: "We repeatedly saw mornings align with better mental health…and midnight with the lowest." The researchers also found that we felt happiest on Sunday mornings, when our anxiety is lower. This is because we have the chance to unwind on Saturdays. We are more likely to have fun and splash out on something nice while shopping. This has a positive impact on our happiness. The researchers said there were other "drivers" that affect our positive feelings. These include the seasons, weather, rain, humidity, and societal factors.
