If you want your wounds (physical ones, whether or not they were caused by your spouse) to heal faster. Wound-healing may be delayed as much as a day, says this report in New Scientist. The underlying research study was done by a team led by Janice Kiecolt-Glaser at the Ohio State University College of Medicine.
The following comment is from Patricia Price of the Wound Healing Research Unit at Cardiff University, Wales, who was not involved in the study:
This study was carried out on healthy people – a lot of them young. So imagine the effect on people who are elderly or already immunosuppressed. Some wounds, such as leg ulceration associated with diabetic foot disease, can take months to heal and the implications of stress for these people could be enormous.
