HLTH 1000 Unit 3 (Final Exam) Study Guide Focus On: Improving Your Sleep Increased exposure to interactive technology may increase alertness compared to just watching television. Artificial light exposure from multiple devices in the hours before we go to bed may suppress the release of melatonin, a hormone that helps regulate biological rhythms and promotes sleep, while increasing alertness and shifting circadian rhythms to a later hour, making it harder to fall asleep. (p. 100) The evidence grows daily for the importance of adequate sleep to overall health and daily functioning. (p. 100) Sleep disruption, particularly when circadian rhythms are disrupted repeatedly, results in an overall disruption of immune functioning.
