1. Mobile Phones

For years there has been debate about the effects of radiation from mobile phones. The debate is still not settled. The newest evidence is that the radiation from the phones does affect your skin.
A new study completed by the Finnish Radiation and Nuclear Safety Authority (STUK) on effects of mobile phone radiation on human skin has examined whether a local exposure of human skin to RF-EMF (the radiation from devices like mobile phones) will cause changes in protein expression in living people.

In the study, a small area of forearm’s skin in 10 volunteers was exposed to GSM signal for one hour. After that skin biopsies were collected from exposed and non-exposed areas of skin and all extractable proteins were examined. The analysis of 580 proteins identified 8 proteins that were statistically significantly affected.

”Mobile phone radiation has some biological effect. Even if the changes are small, they still exist”,

says Dariusz Leszczynski, Research Professor at STUK. According to Leszczynski it is much too early to say will these changes induced by the mobile phone radiation have any effect on health.

The entire article “Mobile phone radiation might alter protein expression in human skin” is available in the BMC Genomics web journal: http://www.biomedcentral.com/1471-2164/9/77/abstract

This is a long way from showing that mobile phones are a significant health risk and even further from showing that mobile phones can cause cancer. For me, it means I won’t be talking for extended periods on my mobile.

2. At your desk

If, like me, you work at a desk, it can be hard to get good exercise. The healthblogger has a post (taken from the LiveSmarter blog) listing 20 exercises you can do at your desk, “deskercises”. It is so good that I would like to quote the whole post, but google penalises you for doing things like that. So I’ll just give you some of the highlights for me and then give you the link.

 

3. Body lift
This is a really easy one. Just place your hands on the arms of your desk chair and lift yourself up. Repeat (if you can).

5. Cherry picking
This exercise can help release tension in your upper body and looks just like it sounds. Stretch your arms up, one at a time, as high as you can, as if reaching to pick fruit out of a tree. Repeat 10 times, alternating sides as you go along.

10. The funky chicken

This is an exercise that can help loosen up your upper body. You just might want to wait until none of your coworkers are looking. Put your fingertips on your shoulders and lift your elbows up and then push them down to your sides, as if you’re trying to fly. Repeat 10 times.


17. Float like a butterfly, sting like a bee

Did you get an email from your boss that’s making you livid? Put that energy to good use and get some muscle tone out of it. Just scoot your chair back (so you won’t actually punch a hole in your computer screen) and do some tae-bo action, punching your arms out in front of you and switching sides.

18. Touch your toes
Another easy exercise that will help you work out some tension and maintain flexibility. Stand up in your chair and let your body hang forward, touching as far down on your body as you can. Then, take your right hand and touch it to your left toe and vice versa.

3. Get Out and About.
So much for the phone and the desk. Now some reason to get out and about – or at least to get some aerobic exercise.

Aerobic exercise has now been shown to protect against stroke as well as heart attack. And this is moderate levels of aerobic activity – you don’t need to be an elite level athlete.

“Fitness has a protective effect regardless of the presence or absence of other stroke risk factors

said Steven Hooker, director of the Prevention Research Center at the University of South Carolina Arnold School of Public Health.

Researchers, led by Steven Hooker, analyzed data on more than 60,000 people — 46,405 men and 15,282 women who participated in the Aerobics Center Longitudinal Study between 1970 and 2001 at the Cooper Aerobics Center in Dallas. The participants were followed for an average of 18 years. (If you remember those aerobics books with lots of charts for all the different kinds of exercises, they were written by the Mr. Cooper who runs this centre.)

“We found that a low-to-moderate amount of aerobic fitness for men and women across the whole adult age spectrum would be enough to substantially reduce stroke risk,” Hooker said.

That corresponds to 30 minutes or more of brisk walking, or an equivalent aerobic activity, five days a week.

So don’t talk too long on the mobile, take a break at the desk, and get out and about for a brisk walk for a half hour each day.
