The number of people who wholeheartedly love getting up early can be counted on both hands. An early start to the day may be a prerequisite for success but may also negatively affect our health.
8 hours of sleep are enough for a person to recharge and rest appropriately. Despite this, even if we get the needed amount of sleep, it's beyond difficult getting up with a smile in the morning. Scientists from Oxford have taken it upon themselves to find out the cause of this phenomenon.
Research has shown that the busy schedule of the majority of people is at odds with their circadian rhythms or so-called biological clock.
These are the cycles that are responsible for the psychological, physical and mood changes in a person. They control every 24 hours of our life. It is indeed our circadian rhythms that tell us when to fall asleep and when to wake up. They are the internal alarm clock of every single person.
That being said, the circadian rhythms are a major part of our lives. Besides sleep, they are practically responsible for every aspect of our lives - when to feel a surge of energy and when not to, when to feel hungry and full. As such, an early start to the day may turn out to be extremely unhealthy because it stands at odds with our natural habits.
The test results show that children between 8 and 10 years of age shouldn't begin their day earlier than 8:30. Those between the ages of 16-18 are best able to work after 10 in the morning, no earlier.
To take maximum advantage of their circadian rhythms, people between the ages of 18-55 also should not begin work before 10 in the morning.
