I wouldn't wear headphones listening to Paraliminals while watching TV. Reading I find it okay. Whether I get more value from it. Not always.
it taks about 20 minutes for your brain to integrate that data. And function at wakening brainwave. If you follow it too closely with another entrainment after a short coming out you can experience side effects like falling asleep, tiredness, headaches and other symptoms. Just enough to spoil your day but nothing long term.
