Comparing 1,101 women with invasive ovarian cancer, 389 with borderline disease and 1,832 without, researchers in Occupational and Environmental Medicine report that ever having worked night shifts was associated with higher risk, with some evidence the risk is lower for night owls.

Breastfeeding cuts the risk of breast cancer - new study
Yumia Sugawara's team followed 26,680 Japanese women aged 40 to 79 for 11 years. Compared with mothers who only breastfed, those who only bottle-fed were 80% more likely to develop breast cancer and 236% more likely to develop endometrial cancer.

Physical activity helps people with hypertension
A Journal of Physical Activity and Health study of 53 adults with newly diagnosed essential hypertension found habitual physical activity at every intensity was inversely associated with pulse wave velocity and augmentation index, two measures of arterial stiffness.

Physical activity good for people at high risk of Alzheimer's disease
A Brain Sciences review finds leisure-time physical activity and exercise training help older adults hold on to cognitive function, most markedly among those at raised genetic risk. Highly active APOE-e4 carriers showed more reduced amyloid burden.

Long lactation or breastfeeding leads to lower risk of ovarian cancer - study
In a case-control study of 493 ovarian cancer patients and 472 controls in Guangzhou, China, women who breastfed more than 31 months had 91 percent lower risk than those who breastfed under 10 months. Breastfeeding three or more children tracked with 62 percent lower risk.

Lifestyle parameters linked to cardiovascular disease
In a Dutch study of 1,626 adults of South Asian Surinamese, African Surinamese and Dutch descent, low physical activity, current smoking and not drinking were associated with 88, 63 and 52 percent higher risk of cardiovascular hospital admission, with no difference by ethnicity.

Tobacco smoking linked to multiple sclerosis
A Swedish case-control study of 192 multiple sclerosis patients and 384 matched controls found that cotinine levels of 10 ng/mL or more carried a 50 percent higher risk of MS. The effect showed only in people under 26.4 years old at blood sampling, where the risk doubled.

Night shift jobs linked to breast cancer - new study
A French case-control study of 1,232 breast cancer patients and 1,317 controls tied night shift work to 27 percent higher risk overall. Women who worked nights for more than four years before their first full-term pregnancy were almost twice as likely to develop the disease.

Extreme Endurance Cardio May Do More Harm than Good
Cardiologist James O'Keefe argues in a TED talk that extreme endurance training can do more harm than good. One study he cites finds benefits plateau past 40 to 50 minutes of vigorous exercise a day, while light daily activity keeps paying off the more you do.

Why Afternoon May Be the Best Time to Exercise
Mercola describes circadian rhythms as an internal clock that times sleep, gene expression and organ signalling, and cites a December 2012 Journal of Physiology study finding exercise helps regulate those rhythms, with the effect possibly strongest in the middle of the day.

Tobacco linked to stroke
A case-control study of 521 first-stroke patients and 1,851 controls in New Zealand found active smokers about four times as likely to suffer a stroke as never-smokers. Passive smoking and past long-term smoking were each tied to 82% higher risk.

Tobacco Smoking Linked to Breast Cancer
A review concludes the evidence points to active smoking as a potential cause of breast cancer, particularly among long-term heavy smokers who started young. Evidence on secondhand smoke is weaker, though premenopausal women exposed to it appear to be at elevated risk.

Tobacco smoking linked to diabetes mellitus type 2
Analyzing 90,819 Norwegians, researchers tied tobacco smoking to a 33 percent higher risk of type 2 diabetes, but only among overweight men. Current smokers showed a 48 percent lower risk of autoimmune diabetes, and heavy smokers 58 percent lower.

Coronary heart disease linked to stress
A meta-analysis of six studies in the American Journal of Cardiology found high perceived stress was associated with a 27 percent higher risk of coronary heart disease.

Cigarette smoking linked to diabetes mellitus type 2
Among 90,819 Norwegians followed from 1984 to 2008, smoking was tied to a 33% higher risk of type 2 diabetes, but only in overweight men. Current smokers had a 48% lower risk of autoimmune diabetes, and heavy smokers 58% lower.

Exercise Helps Your Immune System Protect Against Future Cancers
In a preliminary study, 16 cancer survivors who had just finished chemotherapy did 12 weeks of tailored strength, endurance and flexibility training. Blood analysis showed many of their T cells shifted into a naive form the researchers suggest may fight disease more effectively.

5 Sleep Mistakes You'll Regret Tomorrow
Five habits that work against sleep: hitting the snooze button, keeping an irregular bedtime, taking long daytime naps, eating sugar before bed, and drinking caffeine late in the day. The piece also points to David Randall's book Dreamland on the science of sleep.

Abortion linked to high breast cancer risk
A study in the Asian Pacific Journal of Cancer Prevention compared 263 breast cancer patients with 457 controls at a hospital in Yunnan and reported induced abortion among the risk factors, alongside late first birth, never breastfeeding and oral contraceptive use.
