Such a clock's in vivo period is necessarily almost exactly 24 hours (the earth's current solar day). In most living organisms, internally synchronized circadian ...
The individual's or animal's circadian phase can be known only by the monitoring of some kind of output of the circadian system, the internal "body clock". The researcher can precisely determine, for example, the daily cycles of gene activity, body temperature, blood pressure, hormone secretion or sleep and activity/alertness.
Drinking alcohol can increase the risk of irregular heartbeats, high blood pressure and heart failure, she points out. It also raises the risk of developing obesity and poor sleep patterns, Ruiz adds.
N2 is when the person experiences a light sleep. Eye movement has stopped by this time. Brain wave frequency and muscle tonus is decreased. The heart rate and body temperature also goes down. N3 or even N4 are the most difficult stages to be awakened. Every part of the body is now relaxed, breathing, blood pressure and body temperature are reduced.
