Polyphasic sleep in it's truest form is a sleep pattern with six, twenty minute naps, taken every four hours throughout the day. People use this sleep pattern claim that they can be very productive and have high energy levels, with only two hours sleep per day. It should be noted that the potential health implications of this type of sleep pattern are not known with certainty and anyone experiencing sleep problems or adjusting their sleep pattern, should consult with a medical professional. Recently I've reduced my night's sleep to between 6 and 6.5 hours per night, by taking a 20 minute nap every lunch time. My plan is to slowly reduce my night's sleep to 4.5 hours per night + two, 20 minute naps during the day. What's your opinion on this type of sleep pattern? Do you know anyone who has ever tried it?
