People 2012 (5) - Sleeping Man

Sleep deprivation.

Reports have shown that 80,000 drivers fall asleep behind the wheel everyday.

A study found that sleep deprivation resulted in reduced cortisol secretion the next day, driven by increased subsequent slow-wave sleep. Sleep deprivation was found to enhance activity on the hypothalamic-pituitary-adrenal axis (which controls reactions to stress and regulates body functions such as digestion, the immune system, mood, sex, or energy usage) while suppressing growth hormones.

“Sleep hath its own world, and a wide realm of wild reality. And dreams in their development have breath, and tears, and tortures, and the touch of joy” Lord Byron
