  1. Although I agree that caffeine dehydrates you, this doesn't mean it negates the stimulant effects.

  2. Some symptoms of long covid there's more research for like lung damage or loss of taste. https://astralcodexten.substack.com/p/long-covid-much-more-than-you-wanted Fatigue and especially brain damage can be explained by people who are more likely to report negative symptoms after knowing they have covid.

  3. It does have some bearing on reality if people used it for a long time. There is a tradition and history behind so more are aware of it's effects. The reason it felt good and seemed to help is better than a substance that was recently discovered and uncommonly used.

  4. Yes it's good for the coffee industry but this does not mean it's the primary reason most people agree that it's healthy. Beer is similar in that way and most agree that it's not healthy.

This suggests that a humidity between 50-60% is optimal https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2863430/

I noticed this too. When wearing a bandana as a mask, humidity is building up while exhaling, causing it to be slightly damp.
