My head gets hotter and I do feel some kind of pressure around forehead for “thinking hard under pressure”, but I think it’s mostly the stress hormones and increased blood pressure / flow / heart rate.
Similar thing for looking at a monitor for many hours straight, but that too may be related to eye muscle strain.
What makes me tired is continued social interaction, especially using several languages. It’s fun but tiring. Then it’s always nice to hide in toilet or go for a walk or something, to relax and breath a bit, before continuing. That tiredness is definitely related to “thinking hard” tiredness.
EDIT: no headache. My headaches are almost exclusively due to not drinking enough water timely.
