Describe the significance of adequate sleep to optimal physiological and cognitive function
Dr. Loredo states in the video “Sleep and Sleep Disorders in the Older Adult – Research on Aging” (Loredo, n.d.,) that sleep affects optimal physiological and cognitive functions significantly by improving the ability to learn and in the prevention of diseases, particularly cardiovascular disease. An example of an improvement of a cognitive function is learning. Learning can be furthered by “30, 40, and 50%” (Loredo, n.d.) with sleep habits are improved. This is especially true when students follow the “study, sleep (a good night’s sleep), and take the test” order that Dr. Loredo encourages (Loredo, n.d.). Sleep also affects our health, specifically our cardiovascular health. According to research that Dr. Loredo cited, when a person sleeps six hours or less, their blood pressure increases. A person receiving five hours or less increases the risk for coronary disease. Sleeping no less than seven hours but no more than nine hours improves a person’s health, decreases the blood pressure by 10% to 20%, and helps prevent cardiovascular disease (Loredo, n.d.).
Explain the mechanisms that occur with sleep apnea.
During sleep apnea, the tongue falls back blocking the airflow. The blocked airflow causes pauses in breathing (called apnea,) this is followed by loud snoring and results in brief awakenings (known as arousals.) The outcome is excessive daytime sleepiness. The cycle of sleep apnea…
