- Young people increasingly affected by low quality of sleep
- Depression and fatigue affects the sleep duration of people
- Obesity and high body mass index also result in poor quality of sleep, says research study.
- A person need six hours continuous sleep on an average
- Constituent deprivation of sleep might result in serious health issues
Although many research studies throw light upon factors influencing the quality of sleep, a point to point analysis on sleep duration has been missing all these while, and a recent study in Korea shows that depression and fatigue can decrease the sleep duration even in healthy people.
The research conducted by Joohee Shim and Seung Wan Kang of College of Nursing, Seoul National University, Korea found out that shorter sleep duration was correlated with people having depression and fatigue. Higher body mass index and old age too can act as factors affecting the poor quality of sleep, as per the research study.
According to psychiatrists, in India, people in their younger age have been increasingly affected by low quality of sleep due to various health problems and work stress. While studies point out reasons like psychiatric conditions, usage of medicines, etc. for the lack of sleep and other sleep disorders in aged, in young individuals, the reasons for shifts in sleeping hours and lack of sound sleep were not much put on to study. Proper analysis of the prevailing situation of the low quality of sleep or sleeplessness is needed though in geriatrics and other conditions such studies were conducted already.
A higher body mass index can also act as a reason for shorter sleep duration, says the study which selected 240 individuals for the research.
Increased intake of fat and carbohydrates, with decreased physical activity, which resulted in Obesity, too influenced the sleeping hours while non-obese people reported better sleep duration, indicates the research study.
Meanwhile, Dr. K. S. Shaji, Psychiatrist at Medical College Hospital, Thrissur, Kerala, opines that rather than counting the number of hours of sleep, the continuity should be considered.
While environmental factors can disrupt sleeping hours, depression has been considered as an important factor affecting sleep. It can cause insomnia, which is the inability to sleep. Depression can also result in terminal insomnia, the condition of waking up one or two hours early than normal waking time, for which immediate consultation with a doctor has been suggested.
Doctors also suggest avoiding caffeine intake before going to bed. Smoking too would affect the sleeping hours of an individual.
