Weird Medicine: The Podcast
Deep Dive
Why do sleeping on your arms for extended periods sometimes cause temporary numbness or loss of function?
Sleeping on your arms can restrict blood flow and nerve circulation, leading to temporary numbness or loss of function. This happens because the nerves in the arm don't get enough circulation, similar to how tourniquets are used in surgeries to temporarily cut off blood flow.
What is the difference between allodynia and hyperalgesia?
Allodynia is a pain response to a non-noxious stimulus, like when a sleeping limb is touched and causes pain. Hyperalgesia is an exaggerated response to pain, often seen in people with neuropathic pain or those taking opioids.
Why does RFK Jr.'s nomination as HHS czar raise concerns among some people?
RFK Jr.'s nomination raises concerns because he has been critical of the Democratic Party and has supported Trump, which may conflict with his wife Cheryl Hines' political views. Additionally, his past lawsuits and iconoclastic views on health issues have made him a polarizing figure.
What percentage of the U.S. food supply is made up of ultra-processed foods, and why is this concerning?
Ultra-processed foods make up an estimated 73% of the U.S. food supply. These foods are concerning because they may contribute to the obesity crisis, though not all ultra-processed foods are necessarily harmful. The issue lies in their high carbohydrate content and the USDA's food pyramid, which promoted excessive grain consumption.
What are the potential risks associated with consuming raw milk?
Raw milk can contain harmful pathogens like listeria and E. coli, which can be dangerous for people with weakened immune systems. Pasteurized milk is generally considered safer because it kills these harmful bacteria.
Why is sugar considered a significant contributor to childhood obesity and cardiovascular disease?
Sugar, especially in the form of high fructose corn syrup, contributes to obesity and cardiovascular disease because it spikes insulin levels, leading to increased fat storage and insulin resistance. This can eventually result in type 2 diabetes and other health issues.
What is the controversy surrounding seed oils like canola and soybean oil?
Seed oils like canola and soybean oil have been marketed as heart-healthy due to their unsaturated fats, but some argue they may have negative effects on health. There is ongoing debate about their toxicity, with some studies suggesting they could aggravate metabolic syndrome or contribute to certain health issues.
Why might taking probiotics set off TSA metal detectors?
There is no definitive evidence that probiotics set off TSA metal detectors, but it is possible that the metal content in some probiotic formulations could trigger the alarm. The TSA agents may have been speculating based on the woman's explanation.
Why was branded Coumadin discontinued, and what are the implications for patients on warfarin?
Branded Coumadin was discontinued because its manufacturer, Bristol-Myers Squibb, couldn't profit from it due to competition from newer anticoagulants like Eliquis. Patients on warfarin may face more frequent monitoring and adjustments due to the drug's sensitivity to diet and other factors.
Why is it recommended to sleep in a pitch-black room for better sleep quality?
Sleeping in a pitch-black room is recommended because exposure to even small amounts of light during sleep can harm cardiovascular function and increase insulin resistance. This can lead to metabolic issues like diabetes and obesity. Complete darkness helps maintain the body's circadian rhythm and sleep-wake cycle.
