Seven hours of uninterrupted sleep is essential for a healthy and better living. 

Sleep is one of the most important activities in our lives. Sleep also determines the well-being of the person. However, with the changing trends and busy schedule, often people are sleep deprived.

In India, the prevalence of insomnia is 9% and about 30% suffer from occasional insomnia.  More cases were reported from the urban population in North IndiaThis is due to late-night shifts at work, influence of social media, party culture, television, etc. 

Sleep is also governed by sleep positions. 41% of adults prefer to sleep in the fetal position while only 8% sleep on their back. People with regular eating and sleeping patterns are not affected by lifestyle diseases. 


There have been several studies that highlight the importance of sleep cycle. They describe the association of sleep cycles with lifestyle diseases like diabetes, cholesterol, high blood pressure, etc.  Recently, a study revealed that people who do not follow regular sleeping and waking up schedules, face fluctuations in the amount of sleep they receive every night.

Therefore, they have a higher risk of some lifestyle diseases like obesity, high cholesterol, hypertension, high blood sugar, and other metabolic disorders. In fact, for every hour of fluctuation in sleep, one may be at a 27% greater risk of developing the metabolic disease.


Frequent changes in our time of sleep multiply the adverse effects of metabolism on our body. This is because the metabolic processes like digestion, absorption of nutrients and excretion are disturbed during the sleeping (cycle) hours.

Such people are susceptible to diseases like high depressive symptoms, total caloric intake, and index of sleep. Increasing sleep duration can be associated with multiple metabolic problems such as lower High-Density Lipoprotein (HDL). It may also cause cholesterol and higher waist circumference, blood pressure, total triglycerides, and fasting glucose. 

There has to be proper planning in the sleep timings. An uninterrupted seven hours of sleep during the night is a must for all age groups. The results also suggest that maintaining a regular sleep schedule is important for efficient metabolic functions. This study also promotes the association of metabolic diseases and sleep cycle. Thus, by focusing on sleeping hours and getting sufficient sleep, leads to a  healthy lifestyle. A good amount of sleep will keep your body fit and energetic, mind fresh and would make you happy.

Indian authors named Dr Samhita Panda, Dr Arun B Taly, Dr Sanjib Sinha, Dr G. Gururaj, Dr N. Girish, Dr D. Nagaraja had published a research work in the Journal named Neurology India. The work entitled was ‘Sleep-related disorders among a healthy population in South India’ in the year 2011.  Sleep-related disorders (SRDs) though common, are under-reported and their indications are often ignored. This study aimed to determine the SRDs in healthy South Indian population. With the results of this study, it was concluded that SRDs are common in India. Considering the health implications and poor knowledge, there is a need to generate awareness amongst physicians and the public.
