One important reason why we, as humans, love wholesome content is because it helps build and reinforce hope. Psychologists really can’t overstate just how crucial it is for us to feel like there is a chance the future will be better. Interestingly, researchers have also found a connection between hope and creativity.

After all, making something new means committing to the possibility that his unknown thing will turn out well. Positive thinking, which can be toxic in a few instances, ultimately helps keep our minds active and helps us maintain our desire to keep trying. 

One important part of hope isn't just “teaching” us about the possibility that good things can happen, it’s reminding us that they have happened. Unfortunately, our brains can be a bit selective with what they remember, leading to us “conveniently” forgetting the good things we’ve gone through and just focusing on the bad. 

It is important to remember that hope can be problematic in large “doses” as some people, overwhelmed by positive emotions, can start to develop unrealistic goals and expectations, which will just come to harm them in the long run. This is why real stories are important, but they need to be “tempered” with the help of a specialist, like a therapist, if a person is really going through a depressive spell. 

Researchers have also established a pretty strong connection between hope and not just mental health, but physical as well. People dealing with recovery after injury and illness tend to always do better if they demonstrate or report feelings of hope, versus feelings of intermittent sadness. So when you are looking at a list of wholesome images, perhaps bookmark it for a rainy day, it could actually help.
