You’ve probably heard about a thing called “Biological Clock” and how your sleep circle can affect your overall health. Well if you don’t know what a biological clock means, I’ll tell you. A Biological Clock refers to how your natural body reacts to time. For example, being very strong during your youth and then feeling easily exhausted when you become really old or being fully awake during the day and falling asleep at night or the other way round. In this article, I’ll be talking about 4 different sleep related topics.
1. Negative effects of Sleep Deprivation.
2. How lack of sleep affects your learning process and how you retain knowledge.
3. How much sleep do you really need?
4. Sleep Improvement.
But because sleep is a very broad topic to talk about, I’ll be splitting this article into two parts so as to not bore you.
1. Negative Effects Of Sleep Deprivation.
Sleep deprivation negatively affects the quality of your future sleep routine which will further have a detrimental effect on your health. Not getting enough sleep weakens your immune system and can cause serious consequences. A review based on 16 different studies concludes that people who sleep less than 6 hours a day have a 12% higher rate of premature death than those who sleep over 6 hours daily.
If you constantly yawn, feel sleepy, easily irritated and exhausted during the day, you most likely suffer from sleep deprivation. Not getting enough sleep increases the risks of developing the following problems.
– Changes in hormone functions.
– Visual Impairment.
– Cardiovascular diseases such as high blood pressure.
Also character changes like mood swings, and anger. In worst cases of sleep deprivation, some people even get to have visual hallucinations. Yes, visual hallucinations. Sleep deprivation also causes “Micro-Sleep” which is when an individual falls asleep for few second or minutes without even realising it. This is a very dangerous case and people experiencing this tend to get injured when they fall or trip over something or worse even get involved in a car crash.
According to the American National Highway Traffic Safety Administration, in the US lack of sleep has caused 72,000 crashes, 44,000 injuries and 800 deaths from 2014-2017.
On top of it all, bad sleep habits negatively affects your physical body and appearance and may be seen in weight gain, circles under the eyes and a poor complexion. Long periods of sleep deprivation also leads to lack of concentration, decrease in everyday efficiency/productivity and premature aging.
2. How Sleep Affects Your Learning Process And How You Retain Knowledge.
Being a student, I have to spend tons of hours studying in order to be ahead of my class and that cab be really difficult having to balance your Normal school life which is combination of your class attendance and personal studying, religious life, social life and your overall healthy life. So I had to stay awake about 84% of the day and sleep for just 16% which made me feel so exhausted and the most annoying part was that I wasn’t even retaining so much from all those hours of reading. So I decide to research more about how I could do well in school and also feel strong and healthy and I found this study done some years ago by some psychologists on 3 groups of people and these were the results.
Group A~ 7-8 hours of sleep ~ good cognitive functions.
Group B~ 4-6 hours of sleep ~ significant decrease in cognitive functions.
Group C~ Less than 4 hours of sleep ~ very significant decrease in cognitive functions.
NOTE: Cognitive functions refers to brain functions that lead to knowledge which includes Information acquisition, Reasoning, Memory, Attention, Language and Retainment of information.
Stay tuned for part two.
