It just takes a text: Partner text messages can reduce cardiovascular responses to stress in females

Despite the ubiquity of text messaging, little is known about the physiological impact of receiving texts. This study explored the cardiovascular effects of receiving text messages from romantic partners during a stressor. Seventy-five healthy females received either (1) scripted, supportive text messages from their partners, (2) scripted, mundane text messages from their partners, or (3) no text messages at all (control condition) prior to completing a laboratory stressor. Blood pressure and heart rate were monitored throughout the study. Analyses revealed that systolic blood pressure in response to the stressor was lowest in the mundane text message group and significantly lower than in the other two groups. However, the mundane text message group also exhibited systolic blood pressure that more slowly returned to baseline levels. These findings highlight one potential benefit of text messaging and signal a need for additional work to better understand texting. (C) 2018 Elsevier Ltd. All rights reserved.
