Educational consultant Fintan Connolly shows how the programme works, with the help of 11-year-old Owen Hughes.
Parents often complain that their children spend too much time on computers and it can have an adverse affect on their behaviour.
But this week's Family Focus looks at why some schools in west Belfast are encouraging pupils to log on in order to calm down.
St Clare's Primary School in Cupar Street is using a programme called HeartMath, devised in the US and first introduced in Northern Ireland three years ago.
HeartMath shows children how to change their response to stress - they learn to control their heart rate and deal with feelings of anxiety.
The techniques are used in conjunction with a daily routine called Journey to my safe place which involves the children listening to a CD with their eyes closed and placing their hands on their hearts.
Head teacher Collette White said the children are calmer and better prepared to learn as a result of the programme.
A pilot programme running in a number of schools in the area reported improvements in emotional problems among more than half the pupils and a 43% improvement in their behaviour.
