The main purpose of sleep is to boost our mood. So, you do not look like this.
Sleep is especially important for cute and smart seventh graders, so they can be at their best all day long! They have to sleep for atleast 8 hours so they do not get angry or frustrated and stay happy all day long!
Now coming back to the normal human beings, sleep is important to everybody because:
- It stengthens the memory
- It boosts our energy
- It makes us more creative
- It lowers stress
- It sharpens attention
- It helps us maintain a healthy weight
And these are just a few uses.To get the most out of our sleep, both quantity and quality are important. Children and teens need at least 8 hours—and on average 9¼ hours—a night of uninterrupted sleep to leave their bodies and minds rejuvenated for the next day. If sleep is cut short, the body doesn’t have time to complete all of the phases needed for muscle repair, memory consolidation and release of hormones regulating growth and appetite. Then we wake up less prepared to concentrate, make decisions, or engage fully in school and social activities. Sleeping is an integral part of our life, and as research shows, it is incredibly complex. There are four stages of sleep.
N1 (formerly "stage 1")
- Between being awake and falling asleep
- Light sleep
N2 (formerly "stage 2")
- Onset of sleep
- Becoming disengaged from surroundings
- Breathing and heart rate are regular
- Body temperature drops (so sleeping in a cool room is helpful)
N3 (formerly "stages 3 and 4")
- Deepest and most restorative sleep
- Blood pressure drops
- Breathing becomes slower
- Muscles are relaxed
- Blood supply to muscles increases
- Tissue growth and repair occurs
- Energy is restored
- Hormones are released, such as: Growth hormone, essential for growth and development, including muscle development
REM (25% of night): First occurs about 90 minutes after falling asleep and recurs about every 90 minutes, getting longer later in the night
- Provides energy to brain and body
- Supports daytime performance
- Brain is active all day long
Also, to answer your first question, no we cannot live without sleep. Sleep is as important as the air we breathe in.
