Everything from your bed, sunlight, what you eat and more all play important role in how to sleep well at night

1. How to Sleep Well at Night
Figuring out how to sleep well at night is the key to feeling refreshed in the
mornings. The quality of sleep you're getting is more important than the
quantity. If you want to instantly fall asleep each night and wake up
energized and ready for the day, you need to find out what may be affecting
the quality of your sleep.
Sleep is a mysterious creature. Unattainable to some yet absolute bliss to
those who are lucky enough to find its warm embrace each night.
And if tonight my soul may find
her peace in sleep,
and sink in good oblivion,
and in the morning wake like a new-opened flower
then I have been dipped again in God, and new-created.
~D.H. Lawrence
The amount of time someone needs to sleep each night to be able to
perform well the next day varies from person to person. Some people
happen to function quite well on 4 hours sleep and others can't get out of
bed without 10 + hours of sleep.
For you to be able to figure out what your specific sleep needs are, you're
going to need to experiment. But first you need to figure out how to achieve
QUALITY sleep.

2. Whether someone is able to function well on
4 hours of sleep or 8 or more hours, it's not
the length of the sleep but the quality of the
sleep that affects their performance the next
day. Therefore, you need to figure out how to
get quality sleep before finding your optimal
length of sleep.
There are many factors to take into
consideration when trying to work out your
own personal sleep equation. Everything
from what's on your mind before bed, to
your diet to your exercise schedule (or lack
of one); the amount of sunlight you get, how
comfy your bed is and what you do previous
to going to bed also play important roles in
how to sleep well at night. These, and many
more factors, determine how well and restful
or how 'quality' your sleep will be.
After finding your own personal sleep equation, you will find that your
quality of sleep has increased and as a result, you will have more energy, be
more productive, mentally sharp and emotionally balanced throughout the
day.
