Stress & sleep : the keys of mental well-being

Mental health is defined by the WHO as a state of well-being that enables everyone to cope with the daily challenges of life, to flourish and to contribute to society. Long considered a taboo subject, it is now recognised as a major public health issue, affecting all age groups and social backgrounds.

Two people of the same biological age can age differently depending on their lifestyle and exposure to stress. Studies show that certain intense situations (illness, surgery, pregnancy, long COVID, etc.) accelerate biological ageing – but the good news is that, this effect is partially reversible once the stress has gone.
The same is true for sleep: according to a Swiss study [2], 24 hours of sleep deprivation could age the brain by 1 to 2 years.
