In premenopausal women, the risk of developing atherosclerosis is half that of men. In 1991, Sullivan proposed the iron hypothesis which attributed this decreased risk to premenopausal women's lower blood iron levels, and suggested that blood donation may reduce the risk of developing atherosclerosis. The validity of the hypothesis is still an open ...

Why it has been long assumed that caffeine or coffee is dehydrating? Because caffeine is a mild diuretic - it stimulates water excretion through the kidneys. But the amount of water you consume with caffeinated drinks is usually greater than the amount of water you lose in urine due to caffeine diuretic effect, so there is no net water loss and hence no ...

In addition to alcohol, benzodiazepines and the opiates (rare), another class of drugs that can cause lethal withdrawal symptoms is the barbiturates. In fact, they present the most dangerous withdrawal of all. Their use has largely been replaced with the benzodiazepines, so abuse is much less common today than it was in the 1960s and 1970s. https://...

There is some weak evidence that high intake of fish high in omega-3 fatty acids EPA and DHA (salmon, mackerel, roe, anchovies, tuna, herring, sablefish, sardines) or fish oil capsules might delay wound healing. Here is one experiment about wound healing in rats fed with fish oil: Detrimental effects of an omega-3 fatty acid-enriched diet on wound healing (...

A better comparison than "beard vs toilet" may be "face with beard vs face without beard." This is actually a reasonable concern in the context of healthcare, where healthcare staff can be a vector for disease and where vulnerable people are numerous. If facial hair is a reservoir for disease, it might be reasonable to recommend that healthcare staff remain ...

Stockholm Syndrome does exist. It has an exceptionally high face validity. It does have this attribute due to many case reports available in the non-medical newspapers. You see a pattern, you have a desire to name it. The trick of taxonomy is trying to explain this behaviour pattern, many psychological theories stand at the ready: Traumatic Entrapment, ...

No, nothing will "sober up" a drunk; only time does that. What coffee does is provide caffeine, a stimulant. The stimulant effects will increase alertness, but they will do nothing for perception, coordination, balance or judgement. So, as mentioned in comments, all coffee gives you is an alert drunk. And sure, alcohol plus coffee is two diuretics, so it's ...

The phenomenon you are describing of the pupils dilating when telling a lie has to do with the way the muscles around the eye are wired to the nervous system, and more specifically, the autonomic nervous system. For better understanding, I suggest reading the chapter about neurotransmission in any introductory pharmacology book, such as Katzung's Basic and ...

Males secrete factors that block the development of female ducts and structures. Once the male embryo produces testosterone, the hormone can influence other sex-specific traits around the body. Men having nipples doesn't really have any evolutionary advantage, but it usually doesn't hurt anything either. Barring specific medical conditions—like a tumor on ...

Cairo University's Journal of Advanced Research (PDF) looks at all of the studies on ElectroMagnetic Interferene (EMI) from mobile cellular phones and medical equipment. It says that based on the literature, it was realized that during the initial development of cellular phones, the 2G cellular phones had caused more interference in the functioning of some ...

No. Shaving your facial hair (i.e. beard) or any part of your body for that matter will not make it grow back faster. There is nothing proven scientifically or otherwise that has claimed that when a razor meets your skin does your hair automatically sprout up at a quicker rate. Now there are a few reasons why people might think that this is the case to ...

Yes, both eidetic memory and hyperthemsia exist. And photographic memory has never been proven to exist. But they aren't what pop culture advertises them as. Hyperthemsia first. It is the ability of a person to remember extremely detailed events from most of their life. But it is of limited use. It is an extremely self centered memory condition. Most ...

Stockholm Syndrome certainly does exist. It is a manifestation of capture-bonding, an evolutionary psychology[1] term for the evolved psychological mechanism[2] behind Stockholm syndrome. John Tooby (then a graduate student at Harvard University) originated the concept and its ramifications in the early 1980s, though he did not publish.[3] The term is ...

Evolution tends to select out traits that are harmful (in quite simple terms) AND expressed soon enough to negatively affect reproductive success. Nipples (and breast tissue) on males are extremely unlikely to have a negative effect on reproduction, which means there's no negative selective pressure on them. Since all embryos have the tissue required to ...

You're correct, your friend is indeed gullible. Oropharyngeal candidiasis can be diagnosed by an experienced clinician by looking at the mouth to see characteristic plaques, or by taking swabs for microbiological culture. Blood cultures can be taken for systemic candidiasis. Antibody profiles are suggested as a method to also assist in the diagnosis. The ...
