The Impact of Sitting All Day – Part 4
In part 1, I looked at the impact of sitting on your muscles, and in part 2 generally explored the impact on the rest of your body. In part 3 I focused on the impact of sitting on your circulatory system including your heart. In this article I will explore the impact of sedentary behaviour (sitting) and the link to cancer.
So how common is cancer?
According to Cancer Research UK
- Every two minutes someone in the UK is diagnosed with cancer.
- 1 in 2 people in the UK born after 1960 will be diagnosed with some form of cancer during their lifetime.
- Breast, lung, prostate and bowel cancers together account for over half of all new cancers each year.
- Overall cancer incidence rates in Great Britain have increased by more than a third since the mid-1970s, with almost this entire rise occurring before the late 1990s.
And here is the good news is more people survive cancer than die from it now.
- 46% of men and 54% of women cancer patients diagnosed in 2010-2011 in England and Wales are predicted to survive 10 or more years.
- Cancer survival in the UK has doubled in the last 40 years.
The Link Between Cancer & Inactivity
Last year in a meta-analysis, Daniela Schmid and Michael F. Leitzmann of the University of Regensburg in Germany analyzed 43 observational studies, amounting to more than 4 million people’s answers to questions about their sitting behavior and cancer incidences. The researchers examined close to 70,000 cancer cases and found that sitting is associated with a 24% increased risk of colon cancer, a 32% increased risk of endometrial cancer, and a 21% increased risk of lung cancer.

The really bad news is that your can’t exercise away the harmful effects, “Adjustment for physical activity did not affect the positive association between sedentary behavior and cancer” write Schmid & Leitzmann. Even participants who achieved the daily recommended levels of physical activity were at the same risk as those who spent their day sitting.
One theory as to why this is the case, is that regular movement boosts natural antioxidants that kill cell-damaging and potentially cancer-causing free radicals, another theory is that the excess insulin encourages cell growth.
The pancreas produces insulin, a hormone that carries glucose to cells for energy. But cells in idle muscles don’t respond as readily to insulin, so the pancreas produces more and more. A 2011 study by Stephens et al found a decline in insulin response after just one day of prolonged sitting.

Following on from part 1 on how to treat unirary tract infections naturally here are more tips. Probiotics In a study of postmenopausal women prone to UTIs, a probiotic supplement containting Lactobacillus rhamnosus GR-1 and Lactobascillus reuteri RC-14 cut the number of recurrences by around 50% over a yea. The "good guy" bacteria were almost as effective as antibiotics and they had the advantage of not leading to drug resistant bacteria which may happen with antibiotics. Probiotics also seem to help prevent UTI when use as vaginal suppositories. Ulva Ursi There is evidence to suggest the herby may reduce the duration of a UTI when one strikes. The German Federal Institue for Drugs and Medical devices approves the herb for treatment of UTIs. In one clinical trial, supplements containing standardized extracts of uva ursi as well as dandelion root taken for 1 month effectively prevented UTIs over the following year. Vitamin C Vitamin C may help prevent and treat UTIs by acidifying the urine, creating a hostile environment for infection - causing bacteria. In a study of preganty women, those given daily supplements including 100mg vitamin C experienced significantly fewer UTIs than women given supplements without vitamin C.

Why do muscles get stiff and painful?
Muscle fibers are designed to tense and relax and go through a natural tense/relax cycle as you use your body. A muscle under sustained tension without a corresponding relaxation phase becomes stiff and eventually spams causing pain. There are three reasons why muscles don’t relax:
- Overuse is for example when you injury yourself in the gym.
- Disuse is when your muscles tense when you are at your desk due to the body’s natural response to the demands and pressure you are under. Muscles are designed to be used which means if you sit still for long periods the muscular tension doesn’t dissipate.
- Misuse for the majority of people this is due to poor habits when walking, standing and sitting. Sedentary lifestyles means the muscles of the legs are often held in contracted positions for long periods of time and which can lead to stiffness. Sitting at computers for long hours keeps the neck and back in fixed positions causing the same muscles to contract which can lead to muscle tension and in some people muscle pain.
- Stretching Often - Stretching is, of course, a valuable way to relieve muscle stiffness.
- Exercise - Exercise in general is extremely good for releasing muscular stiffness, improving your mood and creating good health.
- Yoga -You can also consider yoga, which is a form of both exercise and stretching, and may have a positive effect on your future muscle discomfort.
- General Health - Your muscles are also very sensitive to your general health as well. You need to do anything you can to make sure you're getting enough sleep, eating protein, and drinking water. These small changes are going to improve your muscle health, which should improve the way your muscles deal with demanding lifestyles.
- Massage - Massage is an excellent way to combat muscle stiffness and pain.
Smell the wellness
I had always assumed that its just tradition that you buy flowers for somebody that is ill. Speaking as a woman who loves flowers, its always nice to receive flowers but I had underestimated their power. Research completed by the American Society of Horticulture Science discovered that surgical patients exposed to flowers or plants in their recovery rooms have
- lower blood pressure
- lower heart rates
- less pain
- less anxiety
- less fatigue
