Stress has been defined as the “Health Epidemic of the 21st Century” by the World Health Organization, since it represented a big burden for many people (1) and pandemic outbreak has further emphasized this condition. The panic for the health as well as the fear of future uncertainty had totally turned around many aspect of everyday life. Not to mention, the restrictive measures worsen the people emotional status leading to an increase of stress and anxiety at worldwide level. As a consequence, cognitive health market now is rapidly expanding and is projected to reach US$10.7 billion by 2025 (2).
The major area of consumers’ concern is linked to stress management: according to a European market survey made by Innova Market insights, the 47% of consumers associated it with bad mood, while the 41% linked with sleep disruptions (3). On the same trend, another survey made by American Psychological Association found that around 67% of American adults claim to have experienced a stress increment throughout the Covid-19 outbreak, with 78% stating that the pandemic is a significant source of stress in their lives (4).
