Cognitive behavioral therapy for insomnia
The first step in treating insomnia with CBT-I is to identify the underlying causes of the insomnia. People with insomnia should evaluate or have their sleep patterns evaluated and take into account all possible factors that may be affecting the person's ability to sleep. This would involve keeping a sleep diary or journal for a couple weeks. The journal will help to identify patterns of thoughts or behaviors, stressors, etc. that could be contributing to the person's insomnia.
Sleep deprivation
Obstructive sleep apnea is often caused by collapse of the upper airway during sleep, which reduces airflow to the lungs. It has many serious health outcomes if untreated. Positive airway pressure therapy using a CPAP (Continuous positive airway pressure), APAP or BPAP devices is considered to be the first line treatment option for sleep apnea. Mandibular displacement devices in some cases can reposition the jaw and tongue to prevent the airway from collapsing. For some patients supplemental oxygen therapy may be indicated. Nasal problems such as a deviated septum will shut down the airway and increase swelling in the mucus lining and nasal turbinates. Corrective surgery (septoplasty) in some cases may be an appropriate choice of treatment.
