After extensive research and years of work dedicated to understanding mental health, we now have evidence that suggests nearly 2 in 3 of us will experience a mental health problem in our lives, and 1 in 6 is managing fluctuating levels of distress each week.Mental health is an integral part of health; indeed, there is no health without mental health. Mental health is determined by a range of socioeconomic, biological and environmental factors. Cost-effective public health and intersectoral strategies and interventions exist to promote, protect and restore mental health.
