Outline of Final Research Achievements |
In the present study, by analyzing salivary hormones in infants, we examined the effects of quality of sleep and health on post-awakening salivary hormone secretion. We also used a physical activity meter to examine the effects of daytime physical activity on the quality of sleep. Our findings revealed that maintaining a sufficient amount of daytime physical activity may ease the awakening process the following day. Sufficient daily physical activity increases sleep efficiency and helps the body get a good rest during sleep. As a result, the pre-awakening activity of the sympathetic nerves increases, which improves the awakening process. This sequence of events leads to a well-rested feeling. Findings of this study support the common belief that exercising improves the quality of sleep.
