Professor Mark Williams, former director of the Oxford Mindfulness Centre, says that mindfulness means knowing directly what is going on inside and outside ourselves, moment by moment.
"It's easy to stop noticing the world around us. It's also easy to lose touch with the way our bodies are feeling and to end up living 'in our heads' – caught up in our thoughts without stopping to notice how those thoughts are driving our emotions and behaviour," he says.
"An important part of mindfulness is reconnecting with our bodies and the sensations they experience. This means waking up to the sights, sounds, smells and tastes of the present moment. That might be something as simple as the feel of a banister as we walk upstairs.
"Another important part of mindfulness is an awareness of our thoughts and feelings as they happen moment to moment.
"It's about allowing ourselves to see the present moment clearly. When we do that, it can positively change the way we see ourselves and our lives."
