Why a work-free Sunday is more important for workers’ health than any other free day of the week
Health does not only encompass the physical, but also the mental health of workers. The Commission adopts the World Health Organisation’s definition of mental health according to which mental health is “a state of well-being in which the individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community”. A study issued by the DG for Health and Consumers on 13 June 2008 states that mental health
- is affected by policies that influence family life,
- includes concepts such as our ability to initiate and sustain relationships and to play a part in our social world,
- encompasses the ability to develop spiritually.
Finally, in its judgment of 12 November 1996 the ECJ advocated a broad interpretation of the concept of health within the meaning of Article 137 EC Treaty. It refers to the preamble to the Constitution of the World Health Organisation which defines health as the state of complete physical, mental and social well-being that does not consist only of the absence of illness or infirmity.

These findings give strong support to the argument that a free Sunday is ofunparalleled importance for the health of workers
