    1. . It should be noted that stress can be seen as the inverse of “satisfaction” [22], and is relative to a contextual and non-stationary target.
      • for: stress - satisfaction, lack project, poverty mentality, David Loy
      • comment
        • what is interesting is that there is strong emphasis on Buddhist and other contemplative teachings on acceptance of the present state and cessation of searching.
        • In Buddhist teachings, desire is an expression of a dissatisfaction of some aspect of the present and drives change
        • and last but perhaps most importantly, Buddhist teachings teach that the source of the desire is indicative of attachment to the constructed self narrative
        • hence, at first read, it would seem the goal-oriented nature of the definition is at odds with Buddhist teachings.
        • David Loy refers to desires as a way to fulfill something we feel is missing. He refers to this as a "Lack project"
        • If we penetrate the self construct and see it's constructed, provisional nature, then we also expose the greater already existent reality that we already are.
        • It seems paradoxical. While we are strongly reifying the self-construct, we will be goal-seeking and a priority goal may be to experience the self as a construct, which has the effect of ending root level goal seeking.
    2. “stress” (the delta between current state and optimal state, or the difference between the goals at different subsystems’ levels)
      • for: definition, definition - stress, stress
      • comment
        • this is a generalized definition of stress that includes basal cognitive organisms
      • definition: stress
        • In the context of a generalized definition of intelligence applied beyond the traditional definition that applies only to organisms with neurons and nervous systems to include organisms that display basal cognition,
          • stress is defined as the delta between
            • current state and
            • optimal state,
          • or the difference between the goals at different subsystems’ levels
        • Reduction of this stress parameter is a driver that keeps the system exerting energy in action to move and navigate within the problem space.
        • The authors note that stress can be seen as the inverse of “satisfaction”, and is relative to a contextual and non-stationary target.
    1. Die jetzt schon übernutzten Grundwasservorräte in Indien werden durch die globale Erhitzung ab etwa 2040 dreimal so schnell abnehmen wie bisher, wenn sich die landwirtschaftlichen Methoden nicht radikal verändern. Die wachsenden Monsunregenfälle können nicht ausgleichen, was durch trockene Winter und mehr Verdunstung verloren geht. https://www.nytimes.com/2023/09/01/climate/india-groundwater-depletion.html

    1. Dr Lisa van Aardenne, the chief scientist of the University of Cape Town’s climate system analysis group, discussed the use and utility of thermal stress indices. She pointed out that, by the definitions of the universal thermal climate index, much of Africa is under heat stress most days of the year.  Van Aardenne noted that these indices have been developed from a European perspective and do not align with the reality on the ground in Africa. She added: “I’m very concerned that these indices are not fit for purpose here.”

      So for Africa, the figures are so bad that they always look like they're in an emergency? I'm guessing the impact would be that people are more likely to ignore them

    2. Prof Kris Ebi from the University of Washington started off the third day of the conference with a presentation on heatwaves and early action plans. She pointed to the 2021 Pacific north-west “heat dome” event, which resulted in around 800 excess deaths and was later found to be a 1-in-10,000 year event. The rarity of that event means, in effect, “these people died because of climate change,” Ebi said. She added: “Every heat-related death is preventable.”

      I hadn't realised the attribution was so clear like this. Wow.

    1. “My job involves supporting faculty wellness through pedagogy, but also supporting students’ wellness through the practice of pedagogy,”

      Fascinating order in that sentence. I don't think we pay enough attention to the way that course design/practice choices impact faculty wellness.

      The Good Fight S4 E5 "The Gang Goes to War"

      This episode features Diane chatting with a co-star about her note taking experience. The woman indicates that she took notes incessantly and voraciously, but that she never referred back to them. The experience just caused her extreme stress so she gave it up completely as she felt it never gave her any benefit. She resorted instead to a more zen practice of drawing circles in her notebooks. She showed Diane a pile of notebooks filled with circles in various designs and colors. Later in the episode while in court the woman asked Diane about it and Diane showed her some of her new circle "note" pages.

      [Watched the episode passively sometime in the past two weeks.]

    1. Accordingly, poverty acts to reduce overall available bandwidth. It does thisthrough creating greater stress and worries, reduced nutrition, exposure to toxicenvironments, and so on. For example, the constant worry of how to survive ona day-to- day basis acts to reduce bandwidth:Being poor means having less money to buy things, but it also means havingto spend more of one’s bandwidth managing that money. The poor mustmanage sporadic income, juggle expenses, and make difficult trade-offs.Even when the poor are not actually making financial decisions, thesepreoccupations can be distracting. Thinking and fretting about money caneffectively tax bandwidth.23This body of research has demonstrated that it is important to understanddecision- making not only within the socioeconomic context of individuals’lives, but within the psychological context as well.

    1. phytoncides, antibacterial and antimicrobial substances that trees and other plants release into the air to help them fight diseases and harmful organisms. When humans breathe in these substances—typically by spending time in nature—their health can improve. Across several studies, phytoncides have been shown to boost immune function, increase anticancer protein production, reduce stress hormones, improve mood, and help people relax.

    1. Understanding the importance of helping others can also have benefits in your own life, such as reducing your stress. It’s true that you create more responsibility for yourself when you choose to help someone. But this won’t add extra stress to your life. In reality, helping others will allow you to handle stress more easily.

      It's important to understand the valued importance of helping others as it can also help as well especially n the face of reducing your stress. By helping others, you're creating more responsibility, however, this won’t make you feel worse by adding more stress. This is because, helping others allows you to handle stress more easily.

    1. Valter Longo, PhD has been studying an aspect of fasting and autophagy that is fascinating enough, I wanted to include it in it’s own section. One area of his research focuses on how fasting induces differential stress resistance to make chemotherapy far more effective. In a food scarce environment, normal cells become more resistant to oxidative stress, but cancer cells don’t. Remember, cancer cells are broken cells. Something went wrong with them and they are replicating out of control. Being broken means they don’t retain all the typical functions and protective mechanisms of normal cells, like antioxidant generation. That’s one of the reasons cancer cells switch their metabolism from oxidative phosphorylation to glycolysis even in the presence of oxygen. It’s known as the Warburg effect. There are many theories on why this happens, but one is because cancer cells are more sensitive to the reactive oxygen species created during normal metabolism. Eating creates an environment where cancer cells thrive and normal cells are stressed. Cancer cells need an environment rich with sugar, growth factors (like IGF-1) and amino acids like glutamine. For normal cells, metabolism creates reactive oxygen species and triggers an immune response to deal with all the pathogens riding along on top of your meals. However, when you fast, normal cells become 1000 times more resistant to reactive oxygen species, but cancer cells do not. This same starvation-protection also makes normal cells far more resistant to chemotherapy drugs.

      So fasting helps protect healthy cells and weakens cancerous ones. That's cool. But then it says cacer clles need sugar, growth factors like [[IGF-1]] and amino acids like glutamine. The [[Carnivore Diet]] is going to increse IGF-1 and amino acid levels but should starve the cancer cells of sugar. Given Dr Clemens' success treating cancer with the [[PKD]] protocol I'm inferring that it's the triad that needs to be inn place and if sugar is missing then the other factors being elevated eoesn't matter that much.

    1. Nursing professionals are facing with severe sleep problems during the covid 19 pandemic time. Nurses were asked to work in an environment that had a more increased level of risk than ever before. Depression and anxiety from the workplace could affect the confidence of healthcare workers in themselves as well as general trust in the healthcare system. This will lead to their turnover intention which may undermine the efforts of the governments to control the COVID-19 pandemic. The rising concern may change the working schedules of healthcare workers, offering more occupational healthcare support.

    1. Why I chose to step down as CEO of CircleUpOver the past year, when I began telling team members, investors, LPs and other stakeholders about my transition, their first question was, inevitably, “Why?” I typically explained that the average founder/CEO of a startup is in the seat for less than five years; I had been with CircleUp for nine, and I was exhausted. But there was so much more to it than that.I don’t remember the first time I told our board that I was exhausted and needed to step down as CEO. I imagine it was around 2016 or 2017, a period defined by stressful business decisions and physical and mental health issues. I later realized that the board interpreted my complaints as “typical founder/CEO exhaustion”. I blame myself for that lack of clarity. For years I did a poor job of communicating the depth of my stress and exhaustion, a problem only compounded by the fact that, at times, I wasn’t even sure of my own feelings. There were stretches of time where I felt horrible — lonely; terrified; depressed. Depression exacerbates exhaustion. But I tried to put on a brave face to make sure the board felt comfortable.

    1. But isolation plus public shaming plus loss of income are severe sanctions for adults, with long-term personal and psychological repercussions—especially because the “sentences” in these cases are of indeterminate length.

      Putting people beyond the pale creates isolation, public shaming, loss of income, loss of profession, and sometimes loss of personal identity and psychological worth. The most insidious problem of all is the indeterminate length of the "sentence".

      For wealthy people like Harvey Weinstein, Matt Lauer, and Kevin Spacey, they're heavily insulated by the fact that at least they've got amassed wealth which mitigates some of these issues. In these cases the decades of extracting wealth through privilege gives them an unfair advantage.

      There are now apparently enough cases of this happening, it would be interesting to watch the long term psychological effects of this group to see if these situations statistically effects their longevity or if there are multi-generational knock on effects as have been seen in Holocaust survivors or those freed from slavery.

I remember not having anything. On the last day of the month, I opened the freezer, and there's nothing in there.

    1. When you intentionally push yourself outside of your comfort zone and schedule periods of rest and recuperation, something interesting happens: Your capacity to endure stress increases. It’s as if you’ve created a new, set point for what feels normal.

      Constantly pushing yourself past your comfort zones expands your comfort zone.

      A new normal for stress endurance is made as you consonantly push yourself

    2. Our human tendency is to focus on threats and problems. For the sake of our emotional wellness, it makes sense to modify that automatic tendency. You can’t control the stressors that come your way, but you can influence the focus of your own attention. You can focus on the things that give you back a feeling of control.

      We tend to focus attention towards stressors. Instead we should try to focus on things that give us more control of the situation. That way we can face our stressors with more resources.

    1. However, there is still a gap in research efforts moving from laboratory studies to real-world settings. A small number of research has verified when a physiological response is a reaction to an extrinsic stimulus of the participant’s environment in real-world settings.
    1. We developed an automatic stress detection system using physiological signals obtained from unobtrusive smart wearable devices which can be carried during the daily life routines of individuals.

Anything I need to know about major headlines gets surfaced through other channels, or even just other parts of Twitter, so I don't need to see social media updates from media companies whose entire economic model is predicated on causing me enough stress to click through to their sites.

      Some good general advice...
