Floating effective for stress and painRelaxation in large, sound- and light-proof tanks with high-salt water floating is an effective way to alleviate long-term stress-related pain. This has been shown by Sven-ke Bood, who recently completed his doctorate in psychology, with a dissertation from Karlstad University in Sweden.
The dissertation confirms what earlier studies have indicated: sleep was improved, patients felt more optimistic, and the content of the vitalizing hormone........Go to the Psychology news blog (Added on 11/5/2007 9:19:32 PM)
Breaking a sweat means less pounds laterDon't slack off on exercise if you want to avoid packing on the pounds as you age.
A consistently high level of physical activity from young adulthood into middle age increases the odds of maintaining a stable weight and lessens the amount of weight gained over time, as per a new analysis from Northwestern University's Feinberg School of Medicine.

Emotional Intelligence and the use of tobacco and cannabisThe term Emotional Intelligence could be defined as the capacity to perceive, comprehend and regulate one's own emotions and those of others so as to be able to distinguish between emotions and use this information as a guide for one's thoughts and actions.

Fountain of youth for your heart?An age-related decline in heart function is a risk factor for heart disease in the elderly. While a number of factors contribute to a progressive age-related decline in heart function, alterations in the types of fuels the heart uses to produce energy also play important roles. Jason Dyck and his research team at the University of Alberta have been studying the types of fuels used by the heart in young and aged mice.
