We should work less at night

There is growing amount of evidence that doctors' performance is poorer if they work for over-prolonged duties or at night. These working patterns decrease the standard of care and increase the health care expenses. Furthermore, night workers have serious health risks due to their non-physiological work shifts. Effective ways to reduce the overall consequences of fatigue and night work include minimising the amount of work carried out at nighttime and setting up rules for maximal hours for each work shift.
