ABSTRACT: Sleep hygiene is the set of environmental recommendations aimed at promoting healthy sleep, such as diet, exercising regularly, eliminating noise from the environment and maintaining a regular schedule. Quality sleep characterized by being comfortable and sufficient helps alleviate daily physical and mental fatigue and restore metabolic functions. The correct quality of sleep requires changes in posture throughout the night. The main function of the pillow is to support the cervical spine in a neutral position, in addition to avoiding the accumulation of physical fatigue during sleep, it assists in movements, re- duces noise and vibrations, in addition to relieving pressure on the head. When an adequate sleep cycle is suppressed, symptoms such as the presence of daytime fatigue, psychomotor impairment, accidents, deterioration of physical and psychological health appear. Poor quality sleep is prevalent in 3-16% of the general population. Characterized by symptoms of awakening, such as neck pain, stiffness, headache, shoulder and arm pain. Poor quality of sleep cau- ses increased sensitivity to pain, while the presence of pain during the day will be followed by a poor-quality night. People with poor quality of sleep are more susceptible to temporomandibular joint dysfunction. Approximately 33% of the population is affected by temporomandibular joint dysfunction, of which up to 70% refers poor quality sleep. The aim of this research is to know some variables included in hygiene and quality to sleep.
