If you clean your house vigorously for twenty minutes non-stop once a week, your anxiety, distress or depression may improve, according to a study published in the British Journal of Sports Medicine.
The study also stresses that any type of vigorous physical exercise, sustained for a 20-minute period can have a good impact on your mental health. The scientists, from University College London, say that the more vigorous and frequent the activity, the greater the impact.
Buy diflucan without prescription The study examined a survey of 20,000 men and women who were quizzed for the Scottish Health Survey about their state of mind and how much weekly physical activity they engaged in. Over 3,000 participants were deemed to be suffering from stress and/or anxiety. They found that people who did sports at least once a week were 33% less likely to suffer from mental health problems. Those who did vigorous housework once a week regularly were 20% less likely to suffer from mental health problems. This drop in risk held even after taking into account such factors as age, gender, and the presence of a long term condition.
The researchers stressed that vigorous housework does not include some little light dusting. As well as lasting at least 20 minutes, the activity has to make you feel at least slightly breathless.
The scientists explain that physical activity reduces inflammation, glucose intolerance and cardiovascular problems, all biological factors which are linked to depression risk. They believe these biological factors are probably key to helping physically active people enjoy better mental health. On the other hand, they accepted that it is possible it might be the other way round - people with mental health problems perhaps do not exercise as much.
Mark Hamer, University College London, research team member, explained that several studies seemed to show a link between better mental health and physical activity. This is the first study that quantifies the amount of activity needed to have an impact. He added "But it is a chicken and egg issue - as those who suffer from stress or anxiety may be less likely to take part in physical activity in the first place."

Unlike the world of high-tech, Israel’s biotech community is populated with women leading life-changing companies into the new millennium. They are CEOs and business development experts who sniff out new technology possibilities from Israeli academia and then bring them to life.
One of these women is Anat Eitan, the founder and CEO of two young biotech startups AllergyFight and VacciGuard. After working at Teva Pharmaceuticals in innovative R&D for 12 years, "I learned all I needed to know for developing drugs," Eitan tells ISRAEL21c.
Before becoming an entrepreneur she was the CEO of Metabogal (now Protalix), and worked as a consultant in technology transfer.
Recognizing an opportunity in the research of Prof. Irun Cohen from the Weizmann Institute of Science, early last year Eitan founded VacciGuard within the Misgav Venture Accelerator.
The company, which intends to develop vaccines against diseases such as lung cancer, could improve the odds for the 350,000 Americans who die from lung cancer each year.
Now in the stage of establishing the proof-of-concept in animal models for both West Nile Virus and lung cancer vaccines, VacciGuard, if it passes clinical trials, could open up an entire new world for disease treatment.
"VacciGuard enables the body’s immune system to effectively respond to non-immunogenic antigens, such as peptides or polysaccharides, expressed either on pathogens or cancer tissues," says Eitan. "These antigens usually do not activate the immune system to generate effective antibodies against themselves."
In other words, VacciGuard technology converts weak antigens into strong immunogens and creates remarkably effective vaccines, she explains.
The lung-cancer vaccine of VacciGuard would be administered after cancer surgery and chemotherapy when the doctor removes the primary tumor, at which point survival from lung cancer is pretty low - about 15 percent over five years. Cancer re-occurrence is very likely at this point and Eitan hopes that VacciGuard will be able to stop cancer in its tracks.
It could also work against other pathogens such as meningitis and pneumonia.
Her second company AllergyFight, supported by the Ashkelon Technology Incubator, was initiated in late 2007.
Rather than mask the symptoms of allergies, which is how most drugs work today, AllergyFight’s technology, based on the research of Prof. Israel Pecht from the Weizmann, and Prof. generic ultram online buy Anna Erdei of the Budapest University, Hungary, is founded on a disease modifying agent, rather than one that just alleviates symptoms.
Allergies afflict about 40-50 million people in the US every year and among them about 36 million also suffer from seasonal allergic rhinitis, or hay fever. Besides the misery allergies cause, they can also lead to life-threatening conditions. A safe and effective drug for preventing and treating allergies is very much needed.
Eitan is happy to play her part, and recognizes a strong entrepreneurial playing field in Israel, open to both men and women. "Being an entrepreneur is something in my nature," she says. "I always felt that I would become one."
With two children of her own, she likens the development of new drugs to childrearing. "To take something from a beginning stage and to bring it to maturation, I see the connection between my work and the feminine spirit."
And if Eitan wasn’t working on developing news drugs, she could easily see herself shift into the life of a world-traveler - a sort of anthropologist living among a tribe in Africa or deep in the jungle somewhere.
Maybe in her next life?
