Sleep disturbances, diseases more serious
We all have our eyes open at night. We sometimes hear a faint noise, the sound of cars or birds chirping and as a result we move our hands or feet a little and sometimes we take turns. Researchers call this process ‘cortical arrhythmias’. In simple terms it can be called a ‘short period of unconscious awakening’. This kind of semi-awareness affects heart rate, blood pressure and blood flow and is a normal thing.
But if this semi-awakening is continuous at night and sleep is disturbed, then it is a ‘burden’. Researchers who study sleep (polysomnologists) call such repeated awakenings a “nightmare burden.” According to the research of these scientists, the ‘nocturnal burden’ disturbs the cardiovascular system of the human body.
The long-term study involved more than 8,000 people from different test groups. According to research, ‘nocturnal load and cardiovascular disorders or heart disease’ can both lead to death. This shows how dangerous sleep disorders can be.
Heart disease is the leading cause of death in the world. According to the World Health Organization (WHO), “CVDS causes more deaths in the world than any other disease. About 18 million people worldwide have died of heart disease in the past year.
