Superman is one of the most powerful superheroes in the DC universe, but does he need to eat or sleep? The answer is a little complicated. While Superman doesn't need to eat or sleep by human standards, he may choose to do so to fit in and maintain his psychological well-being. Growing up as a human farm boy in Kansas, he developed habits and behaviours like eating and drinking, which he continues even though his body doesn't require it. Superman's body is energised by solar radiation, and he can function without sleep, but he may choose to sleep to process knowledge, memories, and revitalise his brain.

Superman's body may be energised by solar radiation, but he still needs to sleep for psychological reasons
Superman does not need to eat or sleep by human standards. However, he does so to fit in and because of the habits he developed growing up as a human. He was raised as a human for the first 18 years of his life before his powers fully kicked in, and during that time he learned human behaviours, like eating and drinking, and tastes and sensations. He can function in full solar panel mode, but he can also get tired, and he can fall asleep. Even though he can go far longer without sleep than humans, he still needs to sleep to process knowledge, memories, and revitalise his brain and body.
