What is the red band for?

The red bands are from the British Heart Foundation (BHF) charity, which campaigns to fight heart disease.

Conditions like heart attacks are one of the biggest killers in the UK.

The BHF does all sorts of things, like paying for research into heart disease, educating the public and paying for doctors and nurses to be specially trained in dealing with heart problems.

The red bands say 'Feel the pulse' on them.

All of the money raised from them goes to help people affected by heart disease, and to prevent it being such a problem in the future.
