Coconut fragrance and cardiovascular response to laboratory stress: results of pilot testing.

There is preliminary evidence that pleasant fragrances may alter response to stressors in different settings. This pilot study examined the effect of coconut fragrance on cardiovascular response to standard laboratory stressors. While inhaling coconut fragrance (n = 17) or air (n = 15), subjects performed a Stroop color-word task and a mental arithmetic task.

Breast feeding, bottle feeding, and maternal autonomic responses to stress.

Objective: The aim of this study was to examine the effects of breast feeding on autonomic nervous system (ANS) response to stressors.

Methods: Sympathetic and parasympathetic activities were examined before, during, and after standard laboratory stressors in women who were either exclusively breast feeding (n=14) or nonexclusively breast feeding (n=14), and in non-postpartum controls (n=15).

Results: Mothers who breast fed exclusively showed greater levels of parasympathetic cardiac modulation and slower heart rate (HR) throughout the session and less HR increase and preejection period (PEP) shortening to mental arithmetic (MA) than did nonexclusive breast feeders and controls.

Breastfeeding and maternal stress response and health.

This article reviews findings on the maternal stress and health effects of lactation. Several significant associations have emerged. Compared with not breastfeeding, breastfeeding is associated with increased parasympathetic nervous system modulation, greater vascular stress response, lower perceived stress levels, and fewer depressive symptoms.

Cardiovascular reactivity to mental arithmetic and cold pressorin African Americans, Caribbean Americans, and white Americans.

Background: Caribbean Americans and African Americans, two of the largest Black ethnic groups in the United States, differ in cardiovascular-disease-related mortality rates.

Purpose: Cardiovascular reactivity to psychological stress may be an important marker or mediator of risk for cardiovascular disease development in Blacks in the United States, yet little attention has been paid to ethnicity among Blacks in reactivity research. This study examined cardiovascular reactivity to psychological stress in African American, Caribbean American, and White American participants.

Breast-feeding and maternal health in online mothers.

Self-reports of mothers currently breast-feeding (n = 561) and mothers who had breast-fed in the past (n = 452) were compared for perceived stress, self-reports of upper respiratory infection symptoms, and physician visits for psychological illnesses. Possible demographic confounds were controlled statistically. In analyses examining breast-feeding status as a dichotomous variable (current vs.

Breast-feeding is associated with reduced perceived stress and negative mood in mothers.

Two studies examined the effects of breast-feeding on maternal stress and mood. In Experiment 1, perceived stress in the past month was compared between 28 breast-feeding and 27 bottle-feeding mothers. Breast-feeding mothers reported less perceived stress, after controlling for demographic confounds.
