Sleep problems including insomnia are an excellent application of Peripheral Biofeedback and EEG Biofeedback (Neurofeedback). They are also among the major symptoms caused by stress. It is difficult to fall asleep while the body is tense or your brain and nervous system is in fight-fight-freeze (emergency) mode. It is difficult to fall asleep if you close your eyes and your brain is still too busy.
Not getting enough sleep is a problem for between 28.5% – 41.1% of adults in the USA according to CDC 2014 statistics. The term they use is “short sleep duration”, defined as less than 7 hours of sleep per night for adults (see CDC – Data and Statistics – Sleep and Sleep Disorders). People who have short sleep duration also have other health risks at a higher rate than others. Some of these shared risks include obesity, physical inactivity, alcohol use, and smoking.
