Be a morning person to ward off breast cancer risk

Could being a morning or an evening person be a risk factor for breast cancer? A large study suggests that women who are morning people could be at lower risk. They report that they found "consistent evidence" of morning preference having a "protective effect" on breast cancer risk. They also found "suggestive evidence" that sleeping more than 7–8 hours per night could have an "adverse effect" on breast cancer risk. The researchers emphasize that the effects they found are small, compared with that of other risk factors for breast cancer, such as BMI, alcohol consumption, and smoking. In the new study, the researchers carried out two types of analysis. In the first type, they ran a multivariable regression analysis on the UK Biobank data to find links between breast cancer and what each participant reported as their morning or evening preference, sleep duration, and insomnia symptoms. In the second type of analysis, they used participants' genetic profiles of chronotype, sleep duration, and insomnia to look for links between these and breast cancer. The team chose to use MR analysis because their data came from observational studies, which are studies that track people over time. Such studies can only find links between variables, they are not able to prove that one variable actually causes another. Given that the MR analysis confirmed the first set of results, the authors conclude that the "findings provide strong evidence for a causal effect of chronotype on breast cancer risk."

Fact behind reddening of face after drinking alchohol

In this article, we look at why some people experience facial flushing from alcohol, while others do not. We also look at the risks of this side effect and how to prevent it. After having a drink, the body begins to break down the ethanol into other substances, or metabolites, to make it easier to flush out of the body. One of these metabolites, acetaldehyde, is very toxic to the body. When drinking in moderation, the body can usually process these metabolites relatively well. However, if a person is sensitive to alcohol or has a lot to drink, their body may not be able to manage all of those toxins, and acetaldehyde can begin to build up in the body. The red facial flush happens because the blood vessels in the face dilate in response to these toxins. In some people, this can happen after very little alcohol. The red flush that some people get while drinking alcohol may not seem serious, but it can indicate that someone has a higher alcohol sensitivity and may have an increased risk of high blood pressure and certain cancers. While taking antihistamines can help reduce the redness, these drugs only hide the symptoms and do not address the underlying cause. The Centers for Disease Control and Prevention (CDC) recommend that if people choose to drink, they do so in moderation. They define moderate amounts as one drink per day for women and two drinks per day for men. If a person has high alcohol sensitivity, meaning a low tolerance to alcohol, they may feel the effects of alcohol more strongly and quickly and may benefit from drinking less alcohol. People who are concerned about this symptom can talk to their doctor for advice.
