Hedonic adaptation, also known as the "hedonic treadmill," is a psychological concept describing the tendency for individuals to return to a relatively stable baseline level of happiness despite major positive or negative life changes or events. This means that the initial surge of happiness (or sadness) felt after a significant event tends to fade over time, as individuals adapt to their new circumstances. Researchers often refer to hedonic adaptation as the hedonic treadmill because people tend to end up back where they started, returning to their baseline set point.
This cycle can occur after various events, such as making a new purchase, starting a new relationship, or getting a promotion at work. While hedonic adaptation can provide resilience after distressing events, it can also diminish the joy derived from positive experiences. The "double whammy" of the hedonic treadmill is that new experiences are often compared not only to past experiences but also to the experiences of others, potentially raising the baseline for happiness and making it harder to achieve. Overcoming the challenges of hedonic adaptation may involve practicing gratitude, pursuing meaningful goals, and remembering that negative feelings tend to improve over time. It may be possible to adjust your emotional baseline by putting in consistent effort and using effective methods to increase your general level of happiness.
