Circadian rhythm is the internal biological clock that regulates approximately 24 hours cycle of biological processes. It is monitored by the hormone melatonin which is secreted by the pineal gland in the brain. It is so incredible how this small tissue has a significant role in our body system. It is stimulated by external cues such as sunlight and temperature. Circadian rhythm is important in determining the sleeping pattern of human being. Could you imagine that what happen to our sleeping pattern if the circadian rhythm is not performing its function at all? I guess, we sleep all 24 hours a day without conscious awareness of our environment. We do not able to focus in our daily activities and we remain unconscious forever. What about for those who lost circadian rhythm due to Brain injuries or diseases? Do they have other mechanism to accomplish their daily activities or they just simple set up an alarm every day. I am just wondering what happen to them; do they stay conscious and be able to perform the physiological activities without the biological clock? What do you think? People with circadian sleep disorder unable to sleep and wake up at the time required for normal work, school, and social needs. We need to get enough sleep in order make our biological clock work properly so that we are able to accomplish the physiological activities in a time manner.so if we have such a dynamic tissue in our brain why we need an artificial alarm today? We do not need to spend our money for nothing. What we do is just get enough sleep and make our circadian rhythm work well.
