1. Alcohol consumption increases adenosine. https://pmc.ncbi.nlm.nih.gov/articles/PMC6826818/
2. High-flow oxygen reduces adenosine. https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2020.00097/full
3. Caffeine blocks adenosine. https://pubmed.ncbi.nlm.nih.gov/20164566/
4. Adenosine has been associated with cluster headaches. https://pubmed.ncbi.nlm.nih.gov/38127692/
Therefore, I think I'll try reducing adenosine. Coffee is not the only thing that is supposed to work for that. https://selfhacked.com/blog/adenosine-risks/
