Getting overheated or hungry and dehydrated can make irritable employees and may increase risk of sickness. Long shifts or excess stress on the job may leave workers tired which can increase risk of accidents on the job. Adequate breaks to eat and relax or take a short walk or even a short nap can send workers back to the job with better cognitive skills - more alert and maybe even with a solution to a problem they had been working on.
