This quote means that human beings need physical touch like they need the sun’s light to live. Just like sunlight is essential for life, so is physical touch. This can mean different kinds of touch, such as a hug from a friend, a pat on the back from your boss, or a handshake from a stranger. Physical touch can make people feel safe, accepted, and cared for, and can even reduce stress and improve physical and emotional health. Therefore, it is just as important as the sun’s rays.
