SLEEPING

SLEEPING
Relaxed sleeping is a real resetting of the mind. It does refresh and re-charge again.

An act of resetting your mind to its waking up state on the previous morning. It is advisable to scan your mind and run clean up programme before you retire to sleep.

Let me give you some spiritual taste before I take you to the world of research, then we will return together to discuss the reasons why some people suffer from sleep disturbances and how to help them to sleep better. 
In the holy book, it was written: {{ Have We not made the earth an expanse, and the high hills bulwarks?. We have created you in pairs, and have appointed your sleep for repose, and have appointed the night as a cloak, and have appointed the day for livelihood}} . . . the day was designed for us to work and make living, and the night was designed for us to calm down and seek sanctuary. In our night haven, we let ourselves to retire . . . to repose.

Research 

Many people are familiar with the sound of white noise, especially those who owned an analogue TV few years ago. Though hard to describe, it’s a noise containing many frequencies with equal intensities, so unlike a baby crying or the sound of drilling it’s a bland buzz that throws a bit of an audible blanket over every other sound. This "white noise" might be used to cancel out background noise while working, or to help you get to sleep. However, recently, people started talking about a different kind of noise called "pink noise".

Deep sleep is critical to maintaining a robust memory, but both decline with age. In March 2017, a small study published in Frontiers in Human Sciences by Zee et.al, suggested that one easy way for older adults to get deeper sleep and stronger memories is to listen to a certain soothing sound called “pink noise”—a mix of high and low frequencies that sounds more balanced and natural than its better-known cousin, “white noise.”

Pink noise sure sounds a lot more appealing than white noise. So could pink noise be the answer to our tiredness and poor memory?.

In this study, a total of 13 adults ages 60 and older spend two nights in a sleep lab. Each night, they took a memory test, went to sleep wearing headphones, and repeated the same memory test in the morning.

On one night, those adults were played short bursts of pink noise during deep sleep – what Dr. Phyllis Zee, professor of neurology at Northwestern University Feinberg School of Medicine, described to The Time as a “fairly pleasant” noise that “kind of resembles a rush of water” – and on the other night, no noise was played.

A specimen of “pink noise”

It may sound strange, but previous study (J Theor. Biol, 2012 Aug 7) titled: Pink noise: effect on complexity synchronization of brain activity and sleep consolidation, by Zhou J, et al, has found that playing so-called pink noise during sleep improves the memory of younger adults. “We wanted to see if it would work in older people, too,” says senior author prof. Zee. Older people tend to get less slow-wave sleep and are at greater risk for memory impairment.

Older studies have also shown that young people’s memories could be boosted by the noise too.
