We know that physical connection and touch make us feel better if we're feeling down in the dumps. Think of a baby that instantly stops crying when they are picked up. The same happens if you're upset or anxious about something, and someone squeezes your hand or gives you a hug: some of that tension is released, and you start to relax.
So what, now what? The sense of touch can be very nurturing – so if you have a loved one, ask for a foot massage or a back rub, and take turns so that you both benefit. If you are alone, you can massage your feet or your shoulders. When you speak to someone (even in the office) touch them on the arm, or if you know them well, give them a hug.
