SUNDAY, Nov. 27, 2005 (HealthDay News) -- The demands of the season are upon you. And all that socializing, present shopping, decorating and feast preparations can turn this time of year into a stress fest that can affect your health.
"If you are not careful, the holidays take an emotional toll on the body, ranging from increased blood pressure to weakening your immune system," said Gina Kearney, a holistic nurse practitioner and site manager at the Integrative Care Center, affiliated with the Hospital for Special Surgery in New York.
Though it's been widely known that stress can boost a person's heart rate and reduce the ability to fight colds, a new study says that even cholesterol levels can be affected.
According to a study by the University College London published in the November issue of the journal Health Psychology, increased cholesterol levels were found in men and women three years after they were subjected to stress-inducing tasks.
"Some of the participants show large increases even in the short term, while others show very little response," researcher Andrew Steptoe said in a prepared statement.
The research suggested that stress prompts the body to produce more energy in the form of fatty acids and glucose, which requires the liver to produce and secrete more low-density lipoprotein (LDL), the principal carrier of cholesterol in the blood.
Another possibility, the study noted, is that stress interferes with lipid clearance or that it increases production of inflammatory processes that increase lipid production.
Steptoe said that the stress-related cholesterol responses in the study volunteers weren't large but, "the levels are something to be concerned about. It does give us an opportunity to know whose cholesterol may rise in response to stress and give us a warning for those who may be more at risk for coronary heart disease."
