Sleep and Teens--Biology and Behavior
How much sleep do teens need? And how much sleep are they realistically getting? Based on current data, most teens need about 9-plus hours to have the best or most suitable sleep night
Many factors combine to decrease sleep in adolescents. We can think in general of two major factors: biological, the brain processes that regulate the amount and timing of sleep, and behavior, all the psychological, parental, societal, cultural features of teen's life.
These changes lay the ground work for the biological night to occur later during the teen years than before. Circadian Rhythms (daily biological clock) seems to slow down as young people progress through the middle school years. At the same time, the sleep pressure system appears to change in a way that makes it easier to stay awake longer, though without changing the amount of sleep that is needed.
Moreover, many teens have a "technological playground" in their bedrooms: television, computer with 24/7 Internet access, telephones, electronic game stations, MP3 players, and so forth. These technologies provide instant and constant contact with peers. Societal and media pressure to consume these technologies is now higher than ever. Yet society also requires that teens go to school at a time of day that is at odds with their biological and social lives. So we see teens turn to caffeine, late-night Internet and cramming in activity after activity as a means to keep awake.
Problems emerge for lack of sleepFor some, grades begin to suffer as they struggle to keep awake during class and while doing homework. And others may simply feel moody, never knowing how to feel or do their best. Worse still, many teens suffer from both physical and mental illness.
The earlier teens can start this good sleep habit, the easier it will be for them to stay healthy, happy and smart.
A. Sleep experts recommend teens keep consistent sleep and wake schedule

D. The sleep-wake bio-regulatory factors appear to change significantly during adolescence
E. Some teenagers struggle to wake up in the morning, often resulting in late or missed school
F. Teens may be driven to things that can wake them up because they'll fall asleep if they do not
G. However, it is indicated that most teens fall short of this goal, many by a considerable amount.
Life is just like a box. Inside it are happiness and sorrow, failure and success, hope and despair. Life is a learning process. Experiences in it teach us new lessons and make us a better person.
Love
Love plays a key role in our life. Love makes you feel wanted. Without love a person could become cruel and violent. In the early stage of our life, our parents are the ones who show us with unconditional love and care. They tell us what is right or wrong, good or bad. {#blank#}1{#/blank#}.It is only after marriage and having kids that a person understands and becomes sensitive to the feelings of others. Kids make a person responsible and mature and help us to understand life better.
Happiness and Sorrow
Materialistic happiness is shortlived, but happiness achieved by bringing a smile on others gives a certain level of fulfillment. {#blank#}2{#/blank#}.No mind is happy without peace. We realize the true worth of happiness when we are in sorrow. Sorrow is basically due to death of a loved one, failure and despair. But these things are temporary and pass away.
Failure and Success
{#blank#}3{#/blank#}.It helps us to touch the sky, teaches us to survive and shows us a specific way.
Hope and Despair
Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience. {#blank#}4{#/blank#}, because after every night there is a day. Nothing remains the same. We have only one choice—keep moving on in life and be hopeful.
Life teaches us not to regret over yesterday, for it has passed and is beyond our control. Tomorrow is unknown, for it could either be right or dull. {#blank#}5{#/blank#}, so that we will enjoy a better tomorrow.
