Touch is one of the most important of our five senses. It is one of the first senses we develop. One of the most commonly accepted forms of touch among people is also one of the first experiences we have in the world—a hug!

There is no better way to understand the importance of hugs than to lose them. For those who have experienced the loss of hugs, you will know how important they are to share.

A recent research has shown that when people hug, the brain releases the chemical(化学物质) which increases our willingness to trust and reduces fear. It has also shown that hugs are great for your heart.

In 1995, a pair of newly born twins was being cared for in hospital. While one of the twins seemed quite healthy, her sister was not. After trying different medical treatments, the nurse on duty, Gayle Kasparian, placed the twins in bed together. The twins immediately snuggled(依偎) up to each other. As one placed her arm around the other, the weak baby became better gradually(逐渐地). How great the power of a hug is!

The need for hugs doesn’t disappear as we grow older, though it seems we are less willing to give them. Research on people of all ages has proven that a hug is necessary for physical and emotional health.

Without hugs we can become sad. A hug provides safety and gentleness. A hug provides us with social contact, a sense of health and a feeling of importance and belonging.
