Colouring in shapes and patterns can be very relaxing. To do it right it requires attention and care and so can be quite absorbing. At the same time, it is not cognitively demanding freeing up the brain for either mind wandering (day dreaming) and/or unconscious or conscious processing (thinking through) of worries and anxieties. A few colouring sheets are easy to carry and have ready for when necessary.
A book can provide an easy opportunity to escape the stresses of the moment. Whether it is escaping into the fantasy world of a novel or being absorbed by a non-fiction book on your favourite topic; books are generally acknowledged to be a relaxing past-time. Parents of pre-school children often carry books around with them so they are to hand when required. Older children can also benefit from having access to a favourite book when out and about or in school.
Getting outdoors into a different environment is really important and walking helps to regulate breathing, improve blood flow and reduce muscle tension. These all help to promote a more positive mental state. It is not alway convenient to head off for a long walk in a park or the countryside. However, simply adding more walking into the daily routine can help: walking to the local shops; walking to school or if it is too far, parking the car a few roads away (getting off bus or train a stop or two early) and walking the last kilometre or two.
For many of us, the opportunity to wallow in a warm bath at the end of a stressful day is very appealing. The same is true for many children. Bubbles, bath oils and scented candles can all be part of the experience if desired.
