About 80 percent of Japanese working women grow tired on the job and eat sweets, even though eating them actually spurs fatigue.

These are the findings of a survey conducted by Chimeguri Kenkyukai (a blood circulation study association), a group involved in promoting health education and awareness with the support of Kao Corp., a maker of detergents, cosmetics, health food and feminine and baby-care products.

The group asked 1,000 women in their 20s to 40s if they became tired while working and learned that 77.7 percent of them responded affirmatively, particularly during the peak period between 4 p.m. and 5 p.m. Of this total, 28.3 percent said they felt "very tired" while 49.4 percent said they grew "tired."
