Japan NattoKinase Association - It is Monday when people feel most stressed out -

Having Thrombus Prevention Month (20th Jan – 19 Feb, 2011), we, Japan NattoKinase Association conducted a research on the actual situation of stress which is one of the causes of thrombosis. A total of 800 Japanese men and women in their 20s to 50s throughout the country were surveyed. (The details are given below.)

It has been found out that the most of the participants (98.1%) are feeling some sort of stress in everyday situation from this survey. Also Monday is the day people feel most stressed by far compared to other days of the week (61.1%). Focusing on the time of the day, the largest number of participants answered “during working hours”, and “when waking up” was in the second place (36.3%). In addition, the result shows that 63.1% of the participants feel gloomy thinking about the next day on Sunday night. Stress contributes to thrombus generation and thrombus is a cause of brain infarction and heart infarction. Looking at the causes of death for Japanese people, these cerebral vessel disease and cardiac disease follows cancer. Adding those 2 together, the ratio is even more than that of cancer.
According to the research (*1) presented by Department of Cardiovascular Medicine Osaka University Graduate School of Medicine (OACIS), which posses the world’s leading database about myocardial infarction and is the authority of myocardial infarction research, the incidence of myocardial infarction among employees is large on Monday, and especially with males the rate of crisis is 30% higher on Monday compared to other days of the week.
Now regarding the result of our survey as well, it can be said that there is a high risk for thrombosis on Monday morning especially in this cold season, and it is an asymptomatic disease; so extra attention should be paid.
