If our lifestyles were not already fast enough…the advent of the latest tech gadgets, smartphones, convenient internet access, and competitive routines have evolved our lives into unlimited functioning hours with no distinction between day and night time.

The argument, given by the enthusiastic type ‘A’ individuals includes statements like

“I sleep when I have to”

“I sleep less but sleep for good quality hours”

“I compensate my night-time sleep by snoozing in the morning”, and so on

The facts remain quite opposite to the proclaimed statements. Good night sleep is never reimbursed by day-time sleeping. A healthy adult requires a good 7-9 hours/day of sleep, as recommended by the National Sleep Foundation, US (2015). No matter how busy you are, you got to sleep at nighttime. The sun goes down for a reason and your mum made you go to sleep on time for a reason too.

sleep disorder centerContrary to previous notions of a ‘sleep center in the brain’ and a ‘sleep disorder center’, latest research defines sleep as a consequence of series of events that include neurons, brainstem and a plethora of neurotransmitters (chemicals). These events get activated by a complex interaction between external stimuli and our intrinsic circadian rhythm. This results in a sleep-wake cycle that involves multiple areas of the brain. So appointing a single brain area as a sleep center does not justify the intricate mechanism of sleep and sleep disorders.

That is why different sleep disorders require distinctive treatment lines. For example REM sleep behavior disorder treatment follow therapies to control the abnormal activity while sleeping. It targets to tone down the increased muscle activity during sleep.
