Three recent experimental studies focused on low consumption / exposure.949596 In one study, 29 smokers each consumed a single cigarette, immediately after which they had a significant decrease in blood vessel output power and significant increase in blood vessel ageing level and remaining blood volume 25 minutes later, as markers of atherosclerosis.94 In another study, human coronary artery endothelial cells were exposed to the smoke equivalent to one cigarette, which led to activation of oxidant stress sensing transcription factor NFR2 and up - regulation of cytochrome p450, considered to have a role in the development of heart disease.95 These effects were not seen when heart cells were exposed to the vapour from one e - cigarette.95 A study exposed adult mice to low intensity tobacco smoke (two cigarettes) for one to two months and found adverse histopathological effects on brain cells.96

We'll put a link to it in the show notes but what it comes down to and this is something I didn't talk about in that episode is what's called pseudo anemia which is naturally lower hemoglobin levels of athletes so what happens is that aerobic exercise specifically, it expands what's called your plasma volume and this naturally reduces the concentration of your red blood cells so what I mean by that is when you exercise really vigorously, it will, in the short term, while you're exercising, reduce your plasma volume by about 10 - 20 %.

In addition to dizziness, a person with POTS may have low blood pressure and low blood volume, and high levels of norepinephrine upon standing.

Additionally, hemolysis results in release of analytes and enzymes from red blood cells (RBCs), which can falsely elevate many test results.5 Destruction of RBCs yields a lower RBC count.1 Excess fluid released from the lysed RBCs also creates a dilution effect in serum and can result in an artifactually decreased packed cell volume.
