SELLEST OSAST
If you’re reading this in the middle of a heatwave, you’ve probably already noticed your brain isn’t firing on all cylinders. The good news is, it’s not just you.
In this episode, Grace is joined by Professor Binna Kandola OBE to explore the growing body of research showing that as temperatures rise, our ability to do demanding mental work can start to decline.
Together, they unpack why complex cognitive tasks are especially vulnerable, what this means for organisations and education, and how heat is likely to become an increasingly important issue in the years ahead.
They also discuss what workplaces, schools and universities can do differently — from improving airflow to rethinking when demanding work, meetings and exams are scheduled.
