Sleep is important for Happiness. If you have good sleep of 6-8hours it is a healthy sign. The sleep has different stages. When we sleep our unconscious takes control of us and the body does regular repair work during sleep. Any sleep disorder actually interfere in the natural process of healing resulting prolonged issues and unhappiness.
A healthy body goes into four stages in sleep 1. Deep Sleep which should be around 15-20% of your sleeping time this is consider healthy. 2. Light Sleep a healthy bench mark for this is around 45-55%. 3. REM( Rapid Eye Movement)) which should around 15-20% 4. Awake this should be around 10-15%. this vary from individual to individual. You can regulate your sleeping time but quality of sleep depends of several factors such as stress, anxiety and unhappiness.
Challenging a widely accepted notion that the brain controls all aspects of sleep, a new research shows that protein in the muscle can lessen the effects of sleep loss in mice. The finding gives scientists a new target besides the brain to develop therapies for people with excessive sleepiness.
“This finding is completely unexpected and changes the ways we think sleep is controlled,“ said Joseph Takahashi, chairman of Neuroscience at University of Texas Southwestern Medical Center in the US.
The research demonstrated how a circadian clock protein in the muscle, BMAL, regulates the length and manner of sleep. While the protein’s presence or absence in the brain had little effect on sleep recovery, mice with higher levels of BMAL1 in their muscles recovered from sleep deprivation more quickly . In addition, removing BMAL1 from the muscle severely disrupted normal sleep, leading to an increased need for sleep, especially deeper sleep, and a reduced ability to recover.
The finding may eventually lead to therapies that could benefit people in occupations requiring long stretches of wakefulness, from military to airline piloting, Joseph said.
“These studies show that factors in muscles can signal to the brain to influence sleep.If similar pathways exist in people, this would provide new drug targets for the treatment of sleep disorders,“ Joseph said.
