A study says people feel happiest in the mornings, and that midnight is when we feel the bluest. Researchers in London conducted a study on mood, frame of mind, and mental well-being at varying times of the day. They asked participants to rate their feelings of happiness, overall satisfaction with life, and how worthwhile they thought life was. The researchers said: "Generally, things do seem better in the morning." They said: "We repeatedly saw mornings align with better mental health…and midnight with the lowest."

The researchers also looked at which days of the week we felt happiest. They found we felt happiest on Sunday mornings, when feelings of anxiety are fewer. This is perhaps because people have the chance to unwind on Saturdays, when they are more likely to have fun. They might splash out on something nice while shopping. This has a positive impact on making us feel happier. The researchers posited that other "drivers" could affect our feelings of positivity. These include the seasons, weather, rain, humidity, and societal factors.
