Exercise to live four years longer

Exercising can extend your life expectancy by nearly four years, a new study has revealed.  New research gathered studies on the question of whether physical activity increases life expectancy.

The studies offered a range of answers, but among the results, the median increase in life expectancy of both men and women came to 3.7 years each.

The German researchers also discovered that getting your exercise as leisure, rather than, as part of your work may be more beneficial, Discovery News reported.

But that could also be a reflection of an overall healthier lifestyle among those people
who took time to workout during their leisure time. The research was recently published in the Journal of Aging Research.

Sunbeds raise skin cancer risk by 90per cent

Using a sunbed under the age of 35 almost doubles the risk of developing skin cancer, a study has warned.

Scientists found that skin in younger people is more susceptible to cell damage that could eventually trigger tumour growth.

The chance of it becoming cancerous went up by 87 percent — and every extra sunbed session under the age of 35 upped the risk by 1.8 per cent.

For users over 35 there was at least a 20 per cent greater chance of developing cancer.
Some 100,000 adults in the UK have skin cancer, and the number has quadrupled since the late 1970s with the advent of sunbed use and cheap package holidays abroad.

Experts based at the International Prevention Research Institute and the European Institute of Oncology studied more than 12,000 skin cancer victims between 1981 and 2012.

They analysed the impact of sunbed use on men and women from the UK, France, Germany and other European nations.

The study found almost 65,000 cases of the deadliest form of skin cancer — melanoma — can be directly linked to sunbed use and it accounts for almost 900 deaths every year in Europe.

Coloured potato chips can curb overeating

Researchers at Cornell University have found that stacking coloured potato chips with regular potato chips acts as a visual cue to curb your chip intake. As part of an experiment carried out on two groups of college students (98 students total) while they were watching video clips in class, researchers from Cornell’s Food and Brand Lab served tubes potato chips, some of which contained chips dyed red.

Researchers found that the red chips served as subconscious “stop signs” that curtailed the amount of food consumed.

In the first study, the red chips were interspersed at intervals designating one suggested serving size (seven chips) or two serving sizes (14 chips); in the second study, this was changed to five and 10 chips.

Unaware of why some of the chips were red, the students who were served those tubes ate 50 percent less than their peers. “People generally eat what is put in front of them if
it is palatable,” said Cornell Food and Brand Lab director Brian Wansink.

“An increasing amount of research suggests that some people use visual indications such as a clean plate or bottom of a bowl to tell them when to stop eating,” he added.
Wansink said further studies are needed among larger, more diverse groups to determine in what context segmentation cues work.
