The thing we probably hate hearing the most is the sound of our alarm, mostly because we haven't had enough time to sleep.
Sleep deprivation has become a global problem. A scientist at Oxford University, Dr. Paul Kelly, has recently made a discovery that possibly affects most of us.
While examining different forms of modern-day torture, he found that waking up and going to work before 10 am is one of the most common of them all.
Dr. Paul says that everybody has their body clock, also known as Circadian Rhythm, and it's pre-programmed and can't be changed.
"We cannot change our 24-hour rhythms. You cannot learn to get up at a certain time…your liver and your heart have different patterns, and you're asking them to shift two or three hours."
So, if we force ourselves to wake up earlier than our organs and brain are ready, then we're fighting the natural clock, and it can cause many adverse effects on our health.
Kelley believes that lack of sleep is an international issue, and as mentioned earlier, it can be dangerous for our health.
For instance, starting work earlier than 10 am every day can cause sleep deprivation and physical and emotional stress, which can lead to even more dangerous health risks.
"It is hugely damaging to the body's systems because you are affecting physical, emotional, and performance systems in the body…"
According to the scientists, a week with less than six hours' sleep every night leads to 711 changes in how our genes function.
He believes that the work effects will be drastically improved if only we made simple changes in the time we start and end work.
Dr. Kelley and other neuroscientists insisted that it's fundamental to understand the functionality of our body at different ages, especially when it comes to sleep cycles.
Sleep deprivation often starts in adolescence as teenagers are biologically inclined to go to sleep around midnight.
If they're not awake until 10 am, and due to the strict early morning hour school schedules, they are losing an average of 10 hours of sleep every week.
And because the teens tend to stay awake longer into the night on weekends, they'll face difficulty to constantly readjust to the early-to-bed, early-to-rise sleep cycle that's structured for the 55-year-olds.
A British school examined Dr.Kelley's theory that schools should start at 10.00 am rather than 8.30. After some time, the grades of the students were significantly improved, as well as their attendance and general productivity.
So, if we were to incorporate such changes in all sectors of modern society, many people will undoubtedly become more productive, healthier, happier, full of energy and joy, instead of being stressed, fatigued, and addicted to coffee.
