We examined 6 labourers who were working in temperature of 43°C and humidity of 100% by usiug Motokawa, s flicker method for measuring fatigue.
1. The values of flicker threshold ascended as soon as they worked and reached the highest values at the moment when their morning works ended.
After their lunch the values had tendency to turn back to the values before working and began to ascend again by their afternoon working and turned back to the values before working after they finished their working.
2. We can prove the great differences comparing aforesaid results of labourers with that of control people.
