Why Fans Can Be So Relaxing

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
