This Is Why Fans Are So Relaxing - Dr Ekberg

Hi this is Dr. Ekberg so here we are in a

Mexican restaurant in Florida and Pam

just noticed how she was getting relaxed

from the fans so she asked why that was

and the answer is quite simple that if

there's five fan blades and they spin

about one turn per second that becomes a

frequency of five Hertz and your brain

is being stimulated each time a fan

blade passes so that's like in training

the brain to a 5 Hertz frequency which is high

theta or in the theta range

which is a very relaxing frequency that

your brain uses to go to sleep so

that's how fans can relax you
