Cold weather & urination
- Tuesday, 14 January 2014
Whizzing in winter. Why being cold makes you want to ‘go.’
Ever wonder why you have to pee when you’re cold? Although there’s no consensus on why this happens, one popular theory says that when your temperature drops, your body tries to reduce heat loss by constricting blood vessels and reducing blood flow to the outer layers of your body. And because more pressure in needed to pump blood through narrowed veins and arteries, your blood pressure increases. In response, the kidneys extract more fluids from the blood — and excrete it as urine. An old, but often cited study indicates that moderate exercise can prevent cold diuresis, which is the medical term for frequent urination when you’re exposed to the cold.
Weight & Prostate Cancer Survival

Obese men diagnosed with prostate cancer more likely to die from the disease
A man’s weight could be a factor in whether he survives or dies from prostate cancer.
A Kaiser Permanente study patients has found that men who are obese or overweight at the time of their prostate cancer diagnosis are more likely to succumb to the disease than men who are of a healthy weight. Researchers also found a stronger correlation in overweight men with aggressive prostate cancer.
The study was published in the journal Obesity Research & Clinical Practice. It was based on a study of 751 Kaiser Permanent prostate cancer patients who had their prostates removed. They had a radical prostatectomy. Researchers found that men in the study who died from the disease were 50 percent more likely to be overweight or obese.
An Old Remedy As A New Chemo Drug?

Ipecac Syrup Shows Promise As A New Chemo Drug
Ipecac syrup, an erstwhile staple found in many families’ medicine cabinets, shows promise as a new chemotherapy drug for bladder cancer, according to a study conducted by Loyola University Medical Center near Chicago.
The study found that emetine dihydrochloride, an active ingredient in ipecac syrup, used alone or used with a standard chemotherapy drug called cisplatin, inhibited the proliferation of bladder tumor cells. The study also discovered that emetine has little effect on normal cells.
The study was published online in The Journal of Urology.
Years ago, ipecac was used to induce vomiting after ingesting a poison. That practice is no longer recommended.
Skin Disease Associated With Kidney Disease

Psoriasis linked to chronic kidney disease
As if the itchy scales weren’t enough…People moderate to severe psoriasis are also at increased risk of developing kidney disease (CKD). Those with severe psoriasis are almost twice as likely to develop CKD, and four-times more likely to develop kidney failure requiring dialysis than those without the chronic skin disease. The risk is greatest for those with psoriasis affecting 3% or more of their surface skin.
Chronic kidney disease is characterized by progressive loss of kidney function over time. The kidneys filter the blood. CKD often goes unnoticed until it reaches advanced stages.
Researchers at the Perelman School of Medicine at the University of Pennsylvania in Philadelphia discovered the first-time ever association between the two conditions. Their study results were published in the online version of BMJ (British Medical Journal). Researchers examined an electronic medical records database of nearly 144,000 people with the condition in the United Kingdom.
Diet-induced ED may benefit from exercise

Sex & (Ahem…) Size
Your lovemaking may be suffering if you’re a guy with sizable love handles. Obesity can affect a man’s sexual function. It can interfere with blood flow and can cause the male hormone, testosterone, to plummet. Many blame our Western-style diet and its associated weight gain.
Eastern Carolina University researchers put rats on a junk-food diet to test the affects of aerobic exercise. For 12 weeks, the researchers fed one group of rodents food high in sugar and fat. The other group ate healthy rat chow. Half of the animals in both test groups exercised by running on a treadmill five days a week. The researchers’ findings? Rats who ate a Western style diet and stayed sedentary developed ED. Rats who ate the high-sugar high-fat Western-style diet and exercised improved their erectile dysfunction and the function of vessels that supply blood to the heart.
Caveat: Instead of reaching for donut, grab a dumbbell instead.
