If you are one of the 56 percent of adults who drink coffee every day, you may wish to increase your energy, not relaxation. But scientists found that coffee may have the potential to reduce emotional and physical stress. In the same way that coffee affects the brain to keep you alert, it
affects neurotransmitters that can help your body fight the symptoms of
stress and stress-related illnesses.
Research in animals
A
Japanese study examined the coffee and also other components, caffeine
and chlorogenic acid - a type of plant-based antioxidants - useful for
reducing stress in the hippocampus region of the brain of mice. The
researchers looked at the coffee interaction with the brain chemical
serotonin and dopamine, two neurotransmitters associated with emotion. The result, published in "Neuroscience Letters" issue of 2002 found
that coffee reduces the stress chemical response of mice when they were
tested when the condition is stress.
Stress and Blood Pressure
Researchers
in Switzerland found that coffee affects the stress-induced high blood
pressure differently in people who frequently drink compared with those
who rarely drank coffee. Research
shows that coffee causes an increase in blood pressure under stress
situations for which no / rarely drink coffee, but in those who drank
coffee regularly, their blood pressure is not affected by stress. However, a previous study in 1992, published in "Psychosomatic
Medicine," found that six cups of caffeinated coffee a day increases the
heart rate response to mental stress.
Stress Associated With Pregnancy
The
third trimester of pregnancy is stressful for many women because of
physical changes of the body weight, the pressure on the internal
organs, back pain, frequent urination and heartburn. A
team in Japan studied the effects of coffee consumption on stress in
pregnancy, is determined by the level of cortisol, or "stress hormone."
The study results were published in 2006 in the "International Journal
of Gynaecology and Obstetrics," found that cortisol levels in pregnant
women significantly reduced after consuming coffee. However, as MayoClinic.com notes, because caffeine can affect your
baby's heartbeat and may be associated with a slightly increased risk of
miscarriage, you should consume no more than two cups of coffee (each
cup = 8-ounce) a day while pregnant.
Work Related Stress
Coffee
is a 'friend compulsory' at work for most people, but one study
published in 2007 in the journal "Psychoneuroendocrinology" shows that
coffee is not a good thing when present at the work-related stress. Health-care
workers who drank the most coffee had the greatest level of the stress
hormone cortisol in the evening after a day of work. A second unpublished study at the University of Bristol in England
found that caffeinated coffee consumption in the workplace makes men
feel more depressed, although it tends to reduce stress for women.
Stress Related to Lack of Sleep
Staying
up all night to prepare for the exam tomorrow and accompanied by a cup
of coffee is not unusual for students, but if you lack of sleep can be
stressful to your body. A
study published in 2008 in the "Journal of Agricultural and Food
Chemistry" found that the coffee aroma can help combat the stress of
sleep deprivation. When
the researchers tested the aroma of roasted coffee beans on mice in the
laboratory, some of the genes in mice can be activated, including some
that produce proteins with healthful antioxidant activity and reduce
cortisol.
