TFA is about buildings and working environments, but I have been suffering through these same environmental aspects on my bus commute recently. I have a short (35 min avg.) ride with no transfers from my place to the Los Angeles office. The past few months my transit operators have been really inconsistent in the use of the AC on the bus and it's killing me. When I step onto a bus and the wave of warm, moist air hits me I will nearly freak out[0]. I can't help but snap at the operator, "Will ya' turn on the dang AC, please... it's hot in here!". How can 20-40 people just sit there like that and not feel it, or say something about it? With West LA (my area) having such a temperate climate, I suspect the bus operators -- who sit by their own window, and have the boarding door open constantly, providing circulation -- don't seem to know how bad it is in the back. And while it may be 18c or so outside, as you HN folks know, the human body puts out a great deal of heat. I did a little BOTEC the other day, and 40 people on the bus puts out about the same heat as 2 1/2 conventional (open) gas fireplaces (~4kw). I don't care if the windows are open or if its 15c outside -- it's going to get warm in the bus with 4kw of heat burning inside, and that doesn't take into account CO2 levels or water vapor (humidity) increases, which I don't have good maths for. -- [0] TBH, most day's I am titrating some ADD (CII) meds, but I'm sensitive to these conditions even when I'm rolling my normal cognative/CNS self. (I'm from SEUS originally, so maybe I'm hyper tuned to muggy, stuffy air...). edited for layout

One hypothesis I have myself, is that it could be possible for ADHD to be developmentally "caused" by venous/lymphatic insufficiency. In est, the brain notices early on that it can't drain waste amines from the neural cleft through the glymphatic system (because it's underdeveloped), and downregulates their production to compensate. If that were to be true, then you'd expect to see a high correlation between people who have ADHD, and people who are very sensitive to heat. Blood would be pooling toward their extremeties—though not necessarily to the point of causing edema—and keeping them warm, but also making it easier for the environment to overheat/overcool their blood, somewhat similarly to people with third-degree burns. It would also suggest that people with ADHD would feel positively about any medication that causes a parasympathetic response, pushing blood toward their core—caffeine being a primary example.
