Does it really matter if you get enough sleep? Absolutely! Not only
does the
quantity of your sleep matter, but the quality of your sleep is
important as
well. People whose sleep is interrupted a lot or is cut short might not
get
enough of certain stages of sleep. In other words, how well rested you
are and
how well you function the next day depend on your total sleep time and how much
of the various stages of sleep you get each night. So when considering what new mattress to buy consider how important a good night's sleep is and why buying the cheapest option isn't always the best.
Performance: We need sleep to think clearly, react quickly,
and create
memories. Inf act, the pathways in the brain that help us learn and
remember are
very active when we sleep. Studies show that people who are taught
mentally
challenging tasks do better after a good night's sleep. Other research
suggests
that sleep is needed for creative problem solving.
Skimping on sleep has a price. Cutting back by even 1 hour can make
it tough
to focus the next day and can slow your response time. Studies also find
that
when you lack sleep, you are more likely to make bad decisions and take
more
risks. This can result in lower performance on the job or in school and a
greater risk for a car crash.
Mood: Sleep also affects mood. Insufficient sleep can make you
irritable and is linked to poor behavior and trouble with relationships,
especially among children and teens. People who chronically lack sleep
are also
more likely to become depressed.
Health: Sleep is also
important for good health. Studies show that not getting enough sleep or
getting
poor quality sleep on a regular basis increases the risk of having high
blood
pressure, heart
disease, and other medical
conditions.
In addition, during sleep, your body produces valuable hormones. Deep
sleep
triggers more release of growth
hormone, which
fuels growth in children, and helps build muscle mass and repair cells
and
tissues in children and adults. Another type of hormone that increases
during sleep works to fight various
infections. This might explain why a good night's sleep helps keep you
from
getting sick-and helps you recover when you do get sick.
Hormones released during sleep also affect how the body uses energy.
Studies
find that the less people sleep, the more likely they are to be overweight
or
obese, to develop diabetes,
and to prefer eating foods that are high in calories
and carbohydrates.
