How circadian rhythm or body's 24 hour clock affects our health and wellbeing is widely studied and recorded around the globeMany studies have indicated the direct link between circadian rhythm and obesity, circadian rhythm and high blood and even circadian rhythm and cardiovascular diseases.
The foundlings of many studies are in line to support the claim that sleep deprivation may be crucial factor for developing of high blood and heart diseases later onIt's known for a long time now that shift workers, long-distance flight crews and sleep deprived people have an increased risk of heart problems.
The early study carried out by Japanese researchers and published in the Archives of Internal Medicine, show that the risk of heart disease increase 1.68-fold among those who sleep fewer than 7.5 hours per night.
Furthermore, short sleep and high night time blood pressure, increases the risk of cardiovascular disease 4.43-fold.
Another study on women suggested that women sleeping less then 7 hours at night are more inclined to develop high blood pressure, coronary diseases and other medical conditions then men.
Recently, when working on mice, Japanese researchers succeeded to find link between body clock and cardiovascular diseaseThey suggest that malfunction in circadian rhythm may be affecting biochemistry in the body and leading to developing of many health conditions and diseases.
The results of the study are published in the journal Nature Medicine and can be found online.
High blood pressure in turn is linked to heart attack, stroke, kidney damage, and many other medical problems.
There are many essential elements and even genes taking part in keeping the proper function of circadian clock or 24-clock of our bodyIn laboratory tests on mice in the university of Kyoto was found that lack of a pair of molecules called Crypto-chromes can seriously affect and cause to abnormalities in the circadian rhythm.
