Most people understand the important role exercise plays in maintaining and boosting your health. But expensive gym memberships coupled with the busy lives many people lead mean that getting enough exercise is often a non-starter due to the associated expenses and/or a lack of time. The good news though is that new research shows stair climbing, at short intervals that last just a few minutes throughout the day, can improve cardiorespiratory health. For the study, researchers from McMaster University in Hamilton, Canada, led by Martin Gibala, Ph.D., observed two groups of sedentary youngsters. One group climbed three flights of stairs three times a day and had recovery sessions of between one and four hours in between, while the other group did not exercise. At the end of the study period, the cardiorespiratory health of both groups was assessed. The group that performed the stair climbing each day had higher cardiorespiratory fitness than the group that did no exercise. Moreover, the stair climbers were also found to be stronger at the end of the intervention. Jonathan Little, Ph.D., an assistant professor of kinesiology at the University of British Columbia in Okanagan, Canada, and study co-author, said: “We know that sprint interval training works, but we were a bit surprised to see that the stair snacking approach was also effective. “Vigorously climbing a few flights of stairs on your coffee or bathroom break during the day seems to be enough to boost fitness in people who are otherwise sedentary.” So there you have it. You can boost your cardiorespiratory health by simply adding ‘exercise snacks’ into your daily routine.
Using cleaning products regularly can be as bad for your lungs as smoking 20 cigarettes a day, a new study has found. Tracking people with an average age of 34 over a 20-year period, scientists at Norway’s University of Bergen found that women who regularly used cleaning products had lung function decline equivalent to those who smoked 20 cigarettes a day. For the study, the researchers measured the lung function of participants by testing the amount of air they were able to forcibly breathe out. They then examined the results alongside surveys answered by the study participants. They found that women who regularly used cleaning products had noticeably decreased lung capacities, as well as increased rates of asthma. Prof Cecile Svanes, who led the team from Bergen, said: "We feared that such chemicals, by steadily causing a little damage to the airways day after day, year after year, might accelerate the rate of lung function decline that occurs with age". So what should you be using instead of cleaning products? According to the scientists, microfiber cloths and water should be “enough for most purposes”, while keeping your home ventilated and using liquid cleaners, not sprays, could also help lessen the impact of cleaning products.
