Euphoric feelings, also known as 'highs, ' are a state of intense happiness and joy. They can be caused by a variety of things, such as a great accomplishment, a special moment with a loved one, or even a simple act of kindness. Highs are often accompanied by a feeling of elation and a sense of being on top of the world. They can be short-lived or last for an extended period of time, depending on the individual and the situation.
