𝟭. 𝗕𝗿𝗮𝗶𝗻 𝗖𝗼𝗼𝗹𝗶𝗻𝗴 𝗧𝗵𝗲𝗼𝗿𝘆
Study: "Thermoregulatory theory of yawning: What we know from over 5 years of research"
Authors: Gallup & Eldakar
Journal: Frontiers in Neuroscience
DOI: https://doi.org/10.3389/fnevo.2011.00003
Key Finding: Yawning frequency increases with rising brain temperature; acts as a "radiator" for heat dissipation.

𝟮. 𝗔𝗹𝗲𝗿𝘁𝗻𝗲𝘀𝘀 & 𝗔𝗿𝗼𝘂𝘀𝗮𝗹
Study: "Yawning as a brain cooling mechanism: Nasal breathing and forehead cooling diminish yawning" (2014)
Authors: Gallup et al.
Journal: Physiology & Behavior
DOI: 10.1016/j.physbeh.2014.03.032
Key Finding: Yawning increases heart rate by 25-30% for ~15 seconds post-yawn.

𝟯. 𝗖𝗼𝗻𝘁𝗮𝗴𝗶𝗼𝘂𝘀 𝗬𝗮𝘄𝗻𝗶𝗻𝗴 & 𝗘𝗺𝗽𝗮𝘁𝗵𝘆
Study: "Individual variation in contagious yawning susceptibility is highly stable and largely unexplained by empathy or other known factors"
Authors: Bartholomew and Cirulli
Journal: National Library of Medicine
https://pmc.ncbi.nlm.nih.gov/articles/PMC3954725/
Key Finding: 40-60% of people yawn contagiously, linked to social bonding (but not strictly empathy).

𝟰. 𝗢𝘅𝘆𝗴𝗲𝗻/𝗖𝗮𝗿𝗯𝗼𝗻 𝗗𝗶𝗼𝘅𝗶𝗱𝗲 𝗘𝘅𝗰𝗵𝗮𝗻𝗴𝗲
Study: "Yawning: No effect of 3–5% CO2, 100% O2, or exercise" (1987)
Authors: Provine et al.
Journal: Behavioral and Neural Biology
DOI: https://doi.org/10.1016/s0163-1047(87)90944-7
Key Finding: While yawning increases O2 intake, it’s not primarily triggered by low O2 (debunking the "oxygen deficit" myth).

𝟱. 𝗘𝘂𝘀𝘁𝗮𝗰𝗵𝗶𝗮𝗻 𝗧𝘂𝗯𝗲 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻
Study: "Yawning and its physiological significance"
Authors: Gupta et al
Journal: International Journal of Applied and Basic Medical Research
https://journals.lww.com/.../yawning_and_its...
Key Finding: Reviews yawning’s role in pressure regulation (including ear function).
