En la semifinal de Río de Janeiro, cuando Nacho Buse estuvo realmente muy afectado por el calor, leí algo que me llamó la atención: decían que los pelirrojos son más sensibles al calor. Ya habíamos visto casos similares antes de Jannik Sinner sufriendo mucho con las altas temperaturas, y ahora en #RolandGarros volvió a pasar algo parecido. Eso me hizo querer investigar un poco más. Encontré un estudio llamado “Could redheadedness be an adaptation to temperate climate?” o “¿Podría el cabello pelirrojo ser una adaptación al clima templado?” (Charles University, 2020), donde se analizaron 73 personas pelirrojas y 130 no pelirrojas. Los resultados mostraron que los pelirrojos tenían niveles más altos de calcidiol (un precursor de la vitamina D). Los autores plantean que el fenotipo pelirrojo podría ser una adaptación evolutiva a zonas con baja radiación solar, facilitando la producción de vitamina D. En simple: la piel de las personas pelirrojas parece producir vitamina D de forma más eficiente con menos radiación UV. Esto se explica porque tienen menos eumelanina (el pigmento que protege del sol) y más feomelanina, lo que también hace que se quemen más rápido y tengan mayor sensibilidad a la radiación solar. Esto no implica necesariamente una peor tolerancia al calor como tal, pero sí una mayor sensibilidad a la radiación UV y una respuesta distinta de la piel frente al sol. De igual forma, cualquier ser humano jugando en temperaturas tan altas como las que se viven hoy en París va a sufrir, pelirrojo o no pelirrojo. Si hay algún biólogo o médico que quiera aportar con algo para esta data, bienvenido.

You know what’s a major public health concern in Peru 🇵🇪? Road safety. Had 5 people hospitalized in my ward because of motorcycle accidents, thankfully everyone wore helmets.
For me it’s: 1. WC 2. CL 3. PL 4. Copa America 5. Eurocup 6. Libertadores 7. Afcon 8. La Liga 9. Brasilerao 10. Serie A 11. Europa League 12. For me MLS shouldn’t be listed Opinions?
I went unmatched this cycle. Pass, Step2 245, YOG 6, I got 3 IVs with connections last cycle. USCE: 1 year. US Research Experience: 2 years. Research Output: 22 scholarly activities I would appreciate any help and mentorship preparing for the next cycle.
