so we'll finalize today's lesson with
0:02
just a reminder of our takeaways the
0:04
first is that we sleep in stages and
0:06
cycles that there are four main sleep
0:10
stages that progress from light sleep to
0:12
deep sleep and that the combination of
0:15
these sleep stages make up a sleep cycle
0:18
and that there are anywhere from four to
0:20
six sleep cycles per sleep
0:22
interval the next is that there are
0:25
factors that affect our body's
0:27
biological clock or circadian rhythm
0:29
those factors could be our sleep
0:32
environment such as the amount of light
0:35
that we're exposed to or how heavy the
0:37
meals are we eat prior to sleep as well
0:39
as our behaviors such as our exercise
0:42
behaviors our lifestyle and also our
0:45
genetics and then finally restful sleep
0:49
both in the short term and the long term
0:50
is beneficial for our health through our
0:52
immunity our ability to avoid colds our
0:55
metabolism our ability to resist the
0:58
urge to pursue high calorie foods but
1:01
also our memory consolidation to
1:04
remember the factors that we experience
1:06
throughout the day and also our
1:08
stability of our mood so sleep overall
1:11
is a robust way to make sure that we are
1:13
healthy functioning
