Everyone is now running a competitive robotic life due to their lifestyle and a regular schedule from the day starting. The shift working many multinational companies is also playing important role in disturbing routine activities.
In the ancient period, it was said as a proverb that “Boycott Nature means the reduction of the life.” It is very true and we can’t ignore this. Due to activities using digital gadgets including mobile, computers, and other digital media, sound sleep has left away the majority of the people of the world, especially in developing countries.

| [Importance of sound sleep] |
A new study has just revealed the standard sleep duration for a healthy brain. As we know that sleep is very important for our health. A new study result has been published in the journal Nature Aging just revealed standard sleep time to have probably the healthiest brain.
To determine the sleep time necessary for a healthy brain, Christelle Langley, from the Department of Psychiatry at Cambridge University (United Kingdom) and researchers from Fudan University (China) came to analyze data from the UK Biobank of approx. Five lakhs people aged 38-73. The latter had been questioned about their sleep habits, mental health, and well-being. On top of that, about 40,000 people provided brain imaging data and genetic data.
The results thus show that after the age of 40, the optimal duration of sleep is 7 hours is highly recommended. We also learn that shorter sleep time was directly associated with impaired cognitive performance, such as information processing speed, memory, problem-solving ability, and visual attention. Of course, this optimal period of 7 hours of sleep implies sleeping in good conditions. Episodes of awakening during the night can for example impact the optimal efficiency of the brain.
The researchers further add that the results show the importance of having a regular sleep pattern. The researchers then conclude: “7 hours of sleep per night is the optimal amount to maintain good cognitive performance. Finding ways to improve sleep in the elderly could therefore be crucial in helping them maintain good mental health and avoid cognitive decline, especially for patients with psychiatric disorders and dementias.” According to them, the association between insufficient sleep and cognitive decline is caused by the disturbance of deep sleep.
Stay healthy, stay safe...
