“…Increases in state-anxiety are often associated with increases in heart rate and blood pressure (18). Moreover, increases in state-anxiety induced during the days leading up to end of semester exams have been shown to correlate with changes in sympatho-vagal balance, as estimated by pulse rate variability (15). This evidence suggests that increases in heart rate and blood pressure with state-anxiety may be associated with elevated MSNA.…”

Durocher JJ, Lufkin KM, King ME, Carter JR. Social technology restriction alters state-anxiety but not autonomic activity in humans. Am J Physiol Regul Integr Comp Physiol 301: R1773-R1778, 2011. First published September 28, 2011 doi:10.1152/ajpregu.00418.2011.-Social technology is extensively used by young adults throughout the world, and it has been suggested that interrupting access to this technology induces anxiety. However, the influence of social technology restriction on anxiety and autonomic activity in young adults has not been formally examined. Therefore, we hypothesized that restriction of social technology would increase state-anxiety and alter neural cardiovascular regulation of arterial blood pressure. Twenty-one college students (age 18 -23 yr) were examined during two consecutive weeks in which social technology use was normal or restricted (randomized crossover design). Mean arterial pressure (MAP), heart rate, and muscle sympathetic nerve activity (MSNA) were measured at rest and during several classic autonomic stressors, including isometric handgrip, postexercise muscle ischemia, cold pressor test, and mental stress. Tertile analysis revealed that restriction of social technology was associated with increases (12 Ϯ 2 au; range 5 to 21; n ϭ 7), decreases (Ϫ6 Ϯ 2 au; range Ϫ2 to Ϫ11; n ϭ 6), or no change (0 Ϯ 0 au; range Ϫ1 to 3; n ϭ 8) in state-anxiety. Social technology restriction did not alter MAP (74 Ϯ 1 vs. 73 Ϯ 1 mmHg), heart rate (62 Ϯ 2 vs. 61 Ϯ 2 beats/min), or MSNA (9 Ϯ 1 vs. 9 Ϯ 1 bursts/min) at rest, and it did not alter neural or cardiovascular responses to acute stressors. In conclusion, social technology restriction appears to have an interindividual influence on anxiety, but not autonomic activity. It remains unclear how repeated bouts, or chronic restriction of social technology, influence long-term psychological and cardiovascular health.arterial blood pressure; cold pressor test; mental stress; muscle sympathetic nerve activity; psychological stress RECENT STUDIES REPORT THAT 95% of young adults in the United States own cellular phones and use them for multiple functions, such as talking, text messaging, and e-mail (22). Additionally, about 94% of college students report having an online social site, such as Facebook (3). The use of social technology has become a primary method of communication for a majority of young adults, and interrupting the use of these technologies can lead to increased levels of anxiety. Such anxiety may negatively influence an individual's health, yet the extent of this potential anxiety has not been adequately quantified.Increased levels of anxiety (21) are among the numerous factors that may significantly contribute to the development of cardiovascular disease. Augmented responses to autonomic stressors can be used as an early predictor of cardiovascular risk (4,10,11,19,20). For example, hypertensive adults demonstrate augmented sympathetic and pressor responses during isometric handgrip (IHG) and postexercise muscle ischemia (PEMI) compared...

Abstract-We describe an online sleep monitoring service, based on unobtrusive ballistocardiography (BCG) measurement in an ordinary bed. The novelty of the system is that the sleep tracking web application is based on measurements from a fully unobtrusive sensor. The BCG signal is measured with a piezoelectric film sensor under the mattress topper, and sent to the web server for analysis. Heart rate and respiratory variation, activity, sleep stages, and stress reactions are inferred based on the signal. The sleep information is presented to the user along with measurements of the sleeping environment (temperature, noise, luminosity) and user-logged tags (e.g. stress, alcohol, exercise). The approach is designed for longterm use at home, allowing users to follow the development of their sleep over months and years. The service has also a medical use, as sleep disorder patients can be measured for long periods before and after interventions.
