What you would tend to do when you got to the beach is to lie down and do nothing, just watch the waves roll onto the shoreline. This act of doing nothing, followed by letting your mind drift as well as the wide-open spaces are said to factor in on reducing your levels of stress drastically. The ocean is always considered a serene and calming location, as such even the idea of looking forward to a trip to the beach, is said to help in getting rid of stress by scientists that study stress, its factors and how it can be mitigated. This is why you may find that contrary to what your parents said to you when you were younger, it is beneficial to the body to just lie around all day.
