According to a researcher from Oxford University, the world-accepted standard of resuming work by 8 am is against how the human body works. Resumption at work any time before 10 am is tantamount to subjecting the body to torture.

Unfortunately, this is the norm in most parts of the world. The researcher recently researched to establish his theory. His theory states that the human body runs on a body clock called Circadian Rhythm.

According to him, Circadian Rhythm regulates human hormone production, perception of time, brain activity, and even energy levels. If this holds, the implication is that when you begin work before 10 am, you must have interfered with the human biological clock unnaturally. Hence, the body systems react negatively to this interference by losing the collective balance.

Since you can’t change your body’s 24-hour rhythm, you will only end up shifting some organs and systems by about 3 hours. Some of the organs that the interference shifts are the liver and heart.


The 8-hour working day began in the early part of the 20th century. It was developed to enhance factory productivity where production goes on for 24 hours a day and 7 days a week. This idea was adopted by a lot of employers as the standard but the human biological clock was not considered.

Over the years, the human body evolved around the daily cycle of sunlight, but it has yet to adjust to the widely accepted 8 am to 4 pm daily work cycle. In other words, a lot of people suffer from sleep deprivation all over the world. The anomaly has become an international issue.

The researcher suggests that schools should begin at 10 am as against the currently adopted 8.30 am. To prove his point, he put his theory to a test using a particular school. After a certain period of tests and many examinations, his theory was proved right by this test.

The level of attendance and general performance of the students in the school improved clearly. This further indicates that there will be more improvements if the 10 am resumption time is adopted in other spheres of society.


There will be happy, highly productive, and hardworking employees instead of having an over-labored, sleep-deprived, and tired set of employees. And the improvement will reflect in the bottom line of the company. According to the researcher, even though they may not be aware of this, employers who compel their employees to resume work before 10 am subject their employees to both emotional and physical stress. These employees also suffer the risk of having long-term adverse effects.

This is why a lot of Americans consume several cups of coffee a day to induce mental and physical alertness. Over 40 billion dollars that are spent on coffee annually will reduce drastically. If this proposition is adopted.
