Five main specializations in psychology

Cognitive, humanistic, social, developmental, clinical

Symptoms of High Levels of Thyroid Hormones

Difficulties sleeping, Increased heart rate, Feeling anxious

Stage 3 and 4 sleep

Each of these lasts about 30 minutes; deep sleep with very slow delta waves in your brain - more in stage 4 than 3

Stage 1 sleep
