The Science of Stress: From Psychology to Physiology

What goes on in our bodies and minds to cause stress? Watch the Q&A here: https://youtu.be/UYUiX7SqWn0 Subscribe for regular science videos: http://bit.ly/RiSubscRibeStress is our natural reaction to physical or emotional pressure, encompassing everything from too much work to being tortured. But how does stress affect our memory, mood and thinking? And what effect does stress have on our overall health? Vincent Walsh and a panel of experts investigate.Vincent Walsh is a neuroscientist at University College London interested in finding out how the brain works. He is particularly fascinated by the the things we take for granted, like dealing with stressful situations.Joe Herbert is interested in the role of the brain in adaptive responses, with particular reference to the reciprocal interaction between hormones and the brain. He is a Professor at the Department of Clinical Neurosciences at the University of Cambridge.Shane O’Mara is Professor of Experimental Brain Research in Trinity College Dublin. His research focuses on the relations between cognition, synaptic plasticity and behaviour, in the context of brain aging and depression.Julie Turner-Cobb is Professor of Psychology at Bournemouth University. She researches the effects of psychosocial factors, particularly stress, coping and social support, on endocrine functioning across a range of acute and chronic health conditions in adults and children.The Ri is on Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and Tumblr: http://ri-science.tumblr.com/ Our editorial policy: http://www.rigb.org/home/editorial-policy Subscribe for the latest science videos: http://bit.ly/RiNewsletter

Stress Management – Permanent Solutions For Stress Reduction

Stress Management – How stress works, where it comes from, and practical solutions for permanent reduction.The Ultimate Life Purpose Course – Create Your Dream Career: http://www.actualized.org/life-purpose-courseLeo’s Top 140 Self Help Books http://www.actualized.org/booksFull Video Transcript Here: http://www.actualized.org/articles/stress-managementVideo Summary: Stress is one of the most common problems of modern life. Stress is an emotional and chemical response to stimuli around us, but the problem lies inside our heads. Stress is most often associated with lack of time or money, or by relationships at work, home, or with family. Achieving better emotional control helps some folks handle stress much better than others, but some situations are inherently more stressful than others.Ideally, the long-term solution to stress is to overhaul your attitude via personal development work. But while you’re working on that, there are some strategies to help you cope in the short-term.If your stress originates from too little money, the logical answer is to get a better-paying job. Too little time: slow down, prioritize, be realistic, and focus. Multi-tasking is a crazy-making oxymoron. If your stress originates in your relationships, stop blaming other people; stop trying to control other people; and focus on your own life and its direction.The best solution over-all for dealing with stress in the short-term is to know your values and your life’s purpose and to stay grounded in yourself.Disclaimer: All personal development advice and information is provided as-is and may not suit your specific circumstances.

In linguistics, and particularly phonology, stress or accent is relative emphasis or prominence given to a certain syllable in a word, or to a certain word in a phrase or sentence. This emphasis is typically caused by such properties as increased loudness and vowel length, full articulation of the vowel, and changes in pitch. The terms stress and accent are often used synonymously in this context, but they are sometimes distinguished. For example, when emphasis is produced through pitch alone, it is called pitch accent, and when produced through length alone, it is called quantitative accent. When caused by a combination of various intensified properties, it is called stress accent or dynamic accent; English uses what is called variable stress accent. Since stress can be realised through a wide range of phonetic properties, such as loudness, vowel length, and pitch, which are also used for other linguistic functions, it is difficult to define stress solely phonetically. The stress placed on syllables within words is called word stress or lexical stress. Some languages have fixed stress, meaning that the stress on virtually any multisyllable word falls on a particular syllable, such as the penultimate (e.e. Polish) or the first. Other languages, like English and Russian, have variable stress, where the position of stress in a word is not predictable in that way. Sometimes more than one level of stress, such as primary stress and secondary stress, may be identified. However, some languages, such as French and Mandarin, are sometimes analyzed as lacking lexical stress entirely. The stress placed on words within sentences is called sentence stress or prosodic stress. This is one of the three components of prosody, along with rhythm and intonation. It includes phrasal stress (the default emphasis of certain words within phrases or clauses), and contrastive stress (used to highlight an item − a word, or occasionally just part of a word − that is given particular focus).

A stress position, also known as a submission position, places the human body in such a way that a great amount of weight is placed on just one or two muscles. For example, a subject may be forced to stand on the balls of his feet, then squat so that his thighs are parallel to the ground. This creates an intense amount of pressure on the legs, leading first to pain and then muscle failure. Forcing prisoners to adopt such positions is an enhanced interrogation technique used for extracting information.
