Body in shape-wefornews

London, Oct 14, 2017: Want to live a long life? Reducing excess weight and staying in shape may prolong life expectancy by two months, researchers suggested.

The study showed that people who are overweight cut their life expectancy by two months for every extra kilo of weight they carry.

Cigarette smoking and traits associated with lung cancer also had the greatest impact on shortening lifespan.

In addition, body fat and other factors linked to diabetes also have a negative influence on life expectancy, the researchers mentioned.

“Our study has estimated the causal effect of lifestyle choices. We found that, on average, smoking a pack a day reduces lifespan by seven years, whilst losing one kilogram of weight will increase your lifespan by two months,” said Peter Joshi, researcher at the University of Edinburgh in Scotland.

The team took the data from 25 separate population studies and analysed genetic information from more than 600,000 people alongside records of their parents’ lifespan.

People share half of the genetic information with each of their parents. Therefore, certain lifestyle factors become highly influenced by some genes that further impacts life expectancy of people, like, increased alcohol consumption and addiction, the researchers explained, in the paper published in the journal Nature Communications.

The study also identified two new DNA differences that affect lifespan. The first in a gene that affects blood cholesterol levels and reduces lifespan by around eight months.

The second is a gene linked to the immune system which adds around half a year to life expectancy.

“The power of big data and genetics allow us to compare the effect of different behaviours and diseases in terms of months and years of life lost or gained, and to distinguish between mere association and causal effect,” said Jim Wilson, Professor at the varsity.

Cycling, walking in nature may improve your mental health

walk-walking

London, Oct 20: People who commute — walking or cycling — through natural environments are more likely to develop better mental health than those who commute less, according to a new study.

Natural environments included all public and private outdoor spaces that contain ‘green’ and/or ‘blue’ natural elements such as street trees, forests, city parks and natural parks/reserves and all types of water bodies.

“Mental health and physical inactivity are two of the main public health problems associated with the life in urban environments. Urban design could be a powerful tool to confront these challenges and create healthier cities. One way of doing so would be investing in natural commuting routes for cycling and walking,” said Mark Nieuwenhuijsen from the University of Barcelona.

For the study, published in the journal, Environment International, the research team examined nearly 3,600 participants who answered a questionnaire about their commuting habits and their mental health.

The findings showed that respondents commuting through natural environments on a daily basis had on average a 2.74 point higher mental health score compared to those who commuted through natural environments less frequently.

This association was even stronger among people who reported active commuting, the team said.

“From previous experimental studies we knew that physical activity in natural environments can reduce stress, improve mood and mental restoration when compared to the equivalent activity in urban environments,” said first author Wilma Zijlema from the varsity.

“Although this study is the first of its kind to our knowledge and, therefore, more research will be needed, our data show that commuting through these natural spaces alone may also have a positive effect on mental health.”
