Katina Tengesdal/MDN - - Dr. Bahram Kordlar, neurologist and sleep medicine specialist for Trinity Health, views data collected during sleep studies at Trinity’s Sleep Center.

Adults ideally spend about eight hours per day, 56 hours per week, and 2,688 hours per year sleeping. Nearly one-third of daily life is devoted to sleep. Sleep disorders not only interfere with sleep. They can cause a decreased quality of life. Dr. Bahram Kordlar, neurologist and sleep medicine specialist for Trinity Health, explained that several common sleep disorders can cause fragmented sleep. Those disorders include primary and secondary insomnia, sleep disordered breathing conditions such as obstructive sleep apnea, and restless leg syndrome. For patients with untreated disorders, there can be many unwanted effects. “People who have sleep apnea are four times more prone to having high blood pressure,” Kordlar said. “Apnea can also increase the risk of coronary heart disease, and can increase the risk of stroke. Apnea can also increase resistance in our body to insulin, which can aggravate underlying diabetes.
