A new study confirms that e-cigs damage your heart
The damage might not be "as bad" as traditional cigarettes, but it's still pretty bad.
- E-cigarettes reduce the amount of nitric oxide being produced, increasing the likelihood of heart damage.
- Vaping might be "healthier" than smoking traditional cigarettes, but as more research continues to be published, e-cigs are certainly not being shown as "healthy."
- Juul's recent removal of flavored pods from retail outlets was pre-empting forthcoming FDA regulations.
The notion that e-cigarettes are "healthier" than regular cigarettes quickly created another billion-dollar industry. The public imagination in the Information Age allowed for such quick transmission of data, even if these data were bogus. It was bad enough that adults were hooked—good enough for non-smokers, who no longer had to deal with toxic fumes trailing smokers. Then kids started getting hooked; the song changed.
By this fall, nearly 20 percent of middle and high school students have partaken in vaping. The e-cig industry was relying on a lack of credible research, not a surplus of honest studies. A "smaller concentration of toxic substances" does not negate harmful effects; it might reduce them, at best. Forget the addiction question, people simply transferred their cravings to another device, or, worse, an entirely new category of smokers were indoctrinated by flavors like Mango Mangue, Gummi Bear, and Blue Raz Cotton Candy.
Under public pressure, Juul, which controls 70 percent of the e-cig market in the United States, announced it would stop selling most flavored pods in retail outlets, pre-empting FDA plans to tighten regulations on teen smoking. Juul Labs is dedicating $30 million to independent research to battle this trend (transparency about the studies and researchers are hopefully forthcoming; corporations sponsoring research rarely works out well for the public). Their move is equivalent to Nestle launching an anti-sugar crusade to combat youth obesity.
The reality is Juul would have had to have done this anyway, if it hoped to save face. Given how long and hard the cigarette industry has fought regulations and attempted to assert its will into the fabric of society through questionable marketing, it's hard to imagine this as a purely benevolent move. Vaping might be "healthier" than smoking, but the idea that it's not dangerous is laughable.
For example, in August a study at the University of Birmingham discovered that vaping liquid produces inflammatory cytokines, which over the course of decades could contribute to heart problems. Now a new study that was recently presented at the American Heart Association's Scientific Sessions confirms that, like traditional cigarettes, e-cigs cause endothelial cells to produce less nitric oxide, leading to heart damage.
Nitric oxide (NO) is a byproduct shared by almost all forms of organic life. The inner lining of blood vessels (endothelium) use nitric oxide in vasodilation, widening blood vessels, to increase blood flow. Producing less NO results in constricted blood flow, one of the main reasons regular smokers suffer from cardiovascular damage.
The FDA has ordered e-cigarette product makers to devise a plan to keep their devices away from minors, declaring use by teens has reached an 'epidemic proportion'.

Dr. Leila Mohammadi, the lead researcher on this latest study and a postdoctoral fellow at the Cardiovascular Research Institute at the University of California, San Francisco, notes that in this regard, vaping is not much safer than cigarettes.
We showed that blood serum from electronic cigarette users has harmful effects that are similar to that of (tobacco) cigarettes on endothelial cell functions. This harmful effect is likely to adversely affect arteries and cardiovascular health.
University of Louisville professor of medicine, Aruni Bhatnagar, notes that the tobacco industry has a vested interest in promoting the idea that e-cigs are safer. Big players in tobacco, such as R.J. Reynolds, British American Tobacco, and Altria (formerly Phillip Morris) all have vaping divisions that are driving more and more revenue into their coffers. The device changes while the addiction remains the same.
The latest study's principal investigator, Matthew Springer, sums up the whole cigarette vs. vaping debate in the simplest terms possible. It's an argument that anyone employed in the tobacco industry will continue to fight against, regardless of how basic this knowledge is.
Anything you inhale other than clean air seems to be causing vascular problems. Rather than try to find the things to inhale that aren't as bad as cigarettes, we might have to realize (we need) to just breathe clean air.
Sallie Krawcheck and Bob Kulhan will be talking money, jobs, and how the pandemic will disproportionally affect women's finances.
Can an orgasm a day really keep the doctor away?
- Achieving orgasm through masturbation provides a rush of feel-good hormones (such as dopamine, serotonin and oxytocin) and can re-balance our levels of cortisol (a stress-inducing hormone). This helps our immune system function at a higher level.
- The surge in "feel-good" hormones also promotes a more relaxed and calm state of being, making it easier to achieve restful sleep, which is a critical part in maintaining a high-functioning immune system.
- Just as bad habits can slow your immune system, positive habits (such as a healthy sleep schedule and active sex life) can help boost your immune system which can prevent you from becoming sick.
How masturbation affects your brain...<p>Orgasms are a very common human phenomenon. The physical and mental health benefits have been researched frequently as a result, and yet, there is still so much to be learned about how our bodies and brains react to the chemicals and hormones released during and after experiencing this type of sexual release.</p><p>"The amount of speculation versus actual data on both the function and value of orgasm is remarkable" explains Julia Heiman, director of the <a href="https://kinseyinstitute.org/" target="_blank">Kinsey Institute for Research in Sex, Gender, and Reproduction</a>.</p><p>Masturbation causes a rush of <a href="https://www.webmd.com/mental-health/what-is-dopamine" target="_blank">dopamine</a>, which is a chemical that is associated with our ability to feel pleasure. Along with the rush of dopamine that is released during an orgasm, there is also a release of a hormone called <a href="https://www.livescience.com/42198-what-is-oxytocin.html" target="_blank">oxytocin</a>, which is commonly referred to as the "love hormone."<br></p><p>This concoction of chemicals does more than just boost our mood, it also can play a key role in decreasing stress and promoting relaxation. Oxytocin decreases <a href="https://www.webmd.com/a-to-z-guides/what-is-cortisol" target="_blank">cortisol</a>, which is a stress hormone that is usually present (in high volumes) during times of anxiety, fear, panic, or distress. </p><p>According to BDSM and fetish researcher <a href="https://www.psychologytoday.com/us/therapists/dr-gloria-brame-colbert-ga/278388" target="_blank">Dr. Gloria Brame</a>, an orgasm is the biggest non-drug induced blast of dopamine that we can experience. </p><p>By boosting the oxytocin and dopamine levels and subsequently decreasing our cortisol levels, the brain is placed in a more relaxed, euphoric, and calm state. </p>
Masturbation boosts your immune system and raises your white blood cell count.<p>How do those effects on the brain from reaching orgasm translate to boosting our immune system and making our body healthier?</p><p>The increase of oxytocin and dopamine that causes a decrease in cortisol levels can help boost our immune system because cortisol (well-known for being a stress-inducing hormone) actually helps maintain your immune system if released in small doses. </p><p>According to <a href="https://www.health24.com/Sex/Great-sex/incredible-health-benefits-to-masturbating-20181030-2" target="_blank">Dr. Jennifer Landa</a>, a hormone-therapy specialist, masturbation can produce the right kind of environment for a strengthened immune system to thrive. </p><p><a href="https://www.ncbi.nlm.nih.gov/pubmed/15316239" target="_blank">A study</a> conducted by the Department of Medical Psychology at the University Clinic of Essen (in Germany) showed similar results. A group of 11 volunteers were asked to participate in a study that would look at the effects of orgasm through masturbation on the white blood cell count and immune system.</p><p>During this experiment, the white blood cell count of each participant was analyzed through measures that were taken 5 minutes before and 45 minutes after reaching a self-induced orgasm. </p><p>The results confirmed that sexual arousal and orgasm increased the number of white blood cells, particularly the natural killer cells that help fight off infections. </p><p>The findings confirm that our immune system is positively affected by sexual arousal and self-induced orgasm and promote even more research into the positive impacts of sexual arousal and orgasm. </p>
Masturbation can ease and prevent pain, which allows you to achieve the restful sleep that helps your immune system stay strong and healthy.<p>The benefits of masturbation have long been debated, but the more research that is done on the topic the more we understand that there are many positive reactions that happen in our bodies and brains when we orgasm.</p><p>Orgasms can help prevent or mitigate pain, which boosts the immune system, preventing cold and flu symptoms. </p><p>According to neurologist and headache specialist Stefan Evers, about one in three patients experience relief from migraine attacks by experiencing sexual activity or orgasm. Evers and his team <a href="https://www.livescience.com/27642-sex-relieves-migraine-pain.html" target="_blank">conducted an experiment</a> with 800 migraine patients and 200 patients who suffered from cluster-headaches to see how their experiences with sexual activity impacted their pain levels. </p><p>The study showed that 60% of migraine sufferers experienced pain relief after participating in sexual activity that resulted in orgasm. Of the cluster-headache sufferers, about 50% said their headaches actually worsened after sexual arousal and orgasm. </p><p>Evers suggested in his findings that the people who did not experience pain relief from migraines of headaches during their sexual activity did not release as large amounts of endorphins as those who did experience pain relief. </p><p>According to <a href="https://www.sharecare.com/health/chronic-pain/chronic-pain-affect-immune-system" target="_blank">rheumatologist Dr. Harris McIlwain</a>, people who suffer from chronic pain have immune systems that are simply not functioning at full capacity - therefore, alleviating pain (through orgasm, as an example) can help boost the immune system. </p><p>Orgasms can also promote relaxation and make it easier to fall asleep. Serotonin, oxytocin, and norepinephrine are all hormones that are released during sexual arousal and orgasm, and all three are known for counteracting stress hormones and promoting relaxation, which makes it much easier for you to fall asleep.</p><p>There are <a href="https://www.ncbi.nlm.nih.gov/pubmed/1233384" target="_blank">several studies</a> showing that serotonin and norepinephrine help our body cycle through REM and deep non-REM sleeping cycles. During these sleep cycles, the immune system releases proteins called <a href="https://www.sleepfoundation.org/articles/how-sleep-affects-your-immunity" target="_blank"><span id="selection-marker-1" class="redactor-selection-marker"></span>cytokines<span id="selection-marker-2" class="redactor-selection-marker"></span></a>, which target infection and inflammation. This is a critical part of our immune response. Cytokines are both produced and released throughout our bodies while we sleep, which proves the importance of a good sleep schedule to a healthy immune system.</p>
Masturbation promotes a high-functioning immune system; a healthy immune system prevents cold and flu.<p>The immune system is a balanced network of cells and organs that work together to defend you against infections and diseases by stopped threats like bacteria and viruses from entering your system. While there are many things we need to do to keep our immune systems functioning at optimal levels, masturbation (or other means of achieving orgasm) has proven to have positive effects on the immune system as a whole.</p><p>Just as bad habits (such as an inconsistent sleep schedule or harmful chemicals in your body) can slow your immune system, positive habits (such as a healthy sleep schedule and active sex life) can help boost your immune system. </p>
The word "learning" opens up space for more people, places, and ideas.
- The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
- Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
- Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.
The coronavirus pandemic has brought out the perception of selfishness among many.
- Selfish behavior has been analyzed by philosophers and psychologists for centuries.
- New research shows people may be wired for altruistic behavior and get more benefits from it.
- Crisis times tend to increase self-centered acts.
