In recent years, a reported 970 million people globally were living with a mental health issue - with anxiety and depression the most common. Such a statistic is a powerful reminder that mental health challenges are not only widespread but deeply human. 

Why Is It Important to Promote Mental & Physical Wellbeing?

Promoting mental and physical wellbeing is essential, as around 1 in 4 adults in England face a mental health issue each year. Women are disproportionately affected, with 20.7% experiencing common disorders, rising to 28.2% among young women aged 16 to 24. Black or Black British individuals also face significantly higher rates of psychotic disorders. In 2023, 6,069 suicides were registered in England and Wales, a staggering 11.4 deaths per 100,000 people - the highest since 1999. These figures highlight the urgent need for inclusive support systems, awareness campaigns and accessible mental health services to protect vulnerable groups and foster a healthier, more resilient society.
