DESCRIPTION
Why do some of us show only minor effects of stress while others show a more severe and disabling mental and physical decline? This slide share presentation explains how you can use your brain to recognise stress and manage it so as to benefit yourself and others in your lives. Topics addressed include (i) understanding the brain and how it processes emotions, (ii) understanding psychological stress including its sources and consequences and (iii) reducing and preventing stress through the practice of mindfulness (awareness), cognitive restructuring (recognising your thoughts), diet, exercise and progressive relaxation.

Exercise increases ‘neurogenesis’ (growth of neurons) in the
hippocampus - a region important for memory and implicated in cognitive
aging.

Warmer colours indicate higher levels of nerve growth factor in the
hippocampus of [A] exercising animals compared to [B] sedentary
animals - blue indicates the lowest level.
PHYSICAL ACTIVITY ENHANCES MOOD AND COGNITION
MENTAL STIMULATION IS ALSO IMPORTANT
People who read more challenging books develop more neural connections.
When it come to knowledge, you either use it or loose it.
