Regular yoga promotes mindful eating

A new study has revealed that regular yoga practice promotes mindful eating and those who eat mindfully are less likely to become fat.

The study led by Dr Alan Kristal, Fred Hutchinson Cancer Research Centre, showed that regular yoga practice may help prevent middle-age spread in normal-weight people and may promote weight loss in those who are overweight.

The researchers suspected that the weight-loss effect is related to do a sensitivity to hunger and satiety than the physical activity of yoga practice itself.

“In our earlier study, we found that middle-age people who practice yoga gained less weight over a 10-year period than those who did not,” said Kristal.

“This was independent of physical activity and dietary patterns. We hypothesised that mindfulness — a skill learned either directly or indirectly through yoga — could affect eating behaviour,” he added.

The study showed that people who ate mindfully — those were aware of why they ate and stopped eating when full — weighed less than those who ate mindlessly, who ate when not hungry or in response to anxiety or depression.

‘Super sensors’ to ‘sniff out’ cancer

Tel Aviv University researchers have created an electrode-based tiny device which they liken to the sensitive seismographs that pick up tremors of impending earthquakes long before they strike.

Judith Rishpon, TAU’s Department of Molecular Microbiology and Biotechnology, says that the novel device can quickly and precisely detect pathogens and pollution in the environment, and infinitesimally small amounts of disease biomarkers in blood.

She says that the new invention, about the size of a stick of gum, may be applied to a wide range of environments and situations.

The aim is for the device to be disposable and cost about one dollar.

Dream therapy useful treatment

A European Science Foundation (ESF) workshop has found similarities in brain activity during lucid dreaming and psychosis, which suggests that dream therapy may be useful in psychiatric treatment.

Lucid dreaming, when a person is aware that he/she is dreaming, is a hybrid state between sleeping and being awake. It creates distinct patterns of electrical activity in the brain that have similarities to the patterns made by psychotic conditions, such as schizophrenia.

Ursula Voss, University of Frankfurt, Germany, points out that confirming links between lucid dreaming and psychotic conditions offers potential for new therapeutic routes based on how healthy dreaming differs from the unstable states associated with neurological and psychiatric disorders.

New data obtained during the workshop suggests that while dreaming lucidly the brain is in a dissociated state, something that affirms the connection.

Too much TV can up BP risk in kids

Sedentary behaviours such as watching TV and use of computers, videos and video games are likely to increase the risk of high blood pressure in children, finds a new study.

“The clustering of cardiovascular disease risk factors in overweight youth suggests that risks may be immediate and not just indicative of potential future problems,” say the authors.

Although elevated blood pressure is associated with genetic factors, healthy physical, dietary and sleep habits seem to be relevant contributors to blood pressure levels in children.
