““Happiness and relationships One of the strongest predictors (and not only correlates!) of happiness is social relationships. In fact, to be happy we need to spend six to seven hours a day in social settings, and up to nine if our jobs are stressful (Rath & Harter, 2010). This applies regardless of whether we are extraverted or introverted (Froh et al., 2007). In their study of exceptionally happy people (10 per cent of 222 college students), Diener and Seligman (2002) found only one main difference between the happiest and the rest of the students. The very happy people had a rich and fulfilling social life. They spent the least time alone, had good relationships with friends and had a current romantic partner. They did not have fewer negative and more positive events, nor differed on amount of sleep, TV watching, exercise, smoking, drinking, etc. Perhaps not surprisingly, frequency of sexual intercourse is strongly associated with happiness. Marriage usually leads to a rapid increase in SWB, which, unfortunately, comes down after a while. However, it does not return to the starting point, but stays at a higher level than before marriage. So marriage changes the set point of SWB, although this change is not large. However, if your relationship is on the rocks, you are likely to be less happy than people who are unmarried or divorced.””
