A condition of body and mind which typically recurs for several hours every night, in which the nervous system is inactive, the eyes are closed, the postural muscles get relaxed, and consciousness practically suspended.
Along with amount of sleep we get each day, other aspects also contribute to our health and well-being.Signs of poor sleep quality include not feeling rested even after getting enough sleep, repeatedly waking up during the night, and experiencing symptoms of sleep disorders.
Sleep plays a critical role to increase immunity, metabolism, memory power, learning, and other major functions.
Tips for Better Sleep:
We should have a consistent sleep everyday including weekdays i.e sleep at the same time and wakeup at the same time.
We should make our bedroom comfortable ,relaxing,quite.
Remove electronic devices such a mobile ,tv remote etc below the pillow.
Take a lite meal and dont take alcohol before going to bed.
Being physically active during the day can help you fall asleep more easily at night.
Surprising Reasons to get more sleep:
Better health:Study after study has found a link between insufficient sleep and some serious health problems, such as heart disease, heart attacks, diabetes, and obesity.
Less pain:Researchers have found that getting good sleep can supplement medication for pain. If we are not able to sleep due to pain, there are also medications available that combine a pain reliever with a sleep aid.
Better mood:When we are exhausted,we are more likely to be cranky. That is not the exact reason. Not getting enough sleep affects our emotional regulation. When we are overtired, we are more likely to burst into tears, or start laughing uncontrollably.
Clearer Thinking:Sleep loss affects the way we think.It impairs your cognition, your attention, and your decision-making.
Stronger immunity:People who got seven hours of sleep a night or less were almost three times as likely to get sick as the people who got at least eight hours of sleep a night.
Better memory:Our brain process and consolidate our memories from the day. If you don't get enough sleep, it seems like those memories might not get stored correctly and can be lost.
Sleep Mechanisms:
Circadian rhythm and homeostasis–work together to regulate when you are awake and sleep.
1.Circadian rhythms:Direct a wide variety of functions from daily fluctuations in wakefulness to body temperature, metabolism, and the release of hormones.
2.Sleep-wake homeostasis:The homeostatic sleep drive reminds the body to sleep after a certain time and regulates sleep intensity.This sleep drive gets stronger every hour you are awake and causes you to sleep longer and more deeply after a period of sleep deprivation.
The Science of Sleep:
The average adult will spend 36 percent of his or her life asleep.Every day, our brain accumulates metabolic waste as it goes about its normal neural activities.It is crucial for memory consolidation, which is the process that maintains and strengthens your long-term memories.
Optimizing our personal habits and your sleep environment is paramount to successful sleep.
