Stress; when a good thing goes bad | Dr Natalie Riddell | TEDxGuildford

How do different types of stress effect immune function, health and ageing? In this talk, the scientist describes the physiological changes brought about by psychological stress and explores the need to address the growing impact that stress is having on the wellbeing of the population. Natalie recently joined the University of Surrey as a Lecturer in Immunology and Ageing. She gained her PhD in 2010 at the University of Birmingham where Natalie investigated the effects of acute psychological stress, and the concurrent release of adrenaline, upon immune function. Next, she joined UCL to study how the immune system changes with advancing age, and how these alterations may result in increased infection and illness in older individuals. Understanding how stress and stress related hormones may regulate immune function and influence ageing of the immune system is now the main focus of her research. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
