The modern way of living has caused many negative effects on the health of humanity and the natural world at large. Perhaps the most prominent and overlooked effect is the disruption of harmonious sleep.
The “Circadian Rhythm” is our body's natural 24-hour cycle of biological processes, including sleep. Our circadian rhythm is what tells our body when it is time to rise in the morning, and rest at night.
It is easy to tell when your circadian rhythm is out of sync. Signs of a disrupted circadian rhythm include:
Being tired when it is light outside
Being wide awake when it is dark outside
Having difficulty falling asleep early
Having difficulty waking up early
The most significant causes of a disrupted circadian rhythm is a lack of spending time outdoors, and being exposed to too much artificial light.
As natural beings, we are meant to rise and fall in alignment with the sun.
Because of modern living, many people are stuck inside all day at their job. This prevents them from experiencing natural light throughout the day which is essential for maintaining an optimal circadian rhythm.
With the rise of synthetic technology, most of us are exposed to harmful artificial lights such as blue light from cell phones, tablets, and other devices. Exposure to blue light at night is especially disrupting to one's circadian rhythm.
When the sun goes down, your body will naturally release melatonin (sleep hormone) to help you begin the process of going to sleep. However, if you expose yourself to blue light at night, your brain will think it is still daytime which means melatonin release will be inhibited, keeping you awake when you should be tired.
