Facts About Sleep
- Human’s sleep is governed by daily Circadian Rhythm. We possess different types of rhythms, some rhythms make us feel sleepy, hungry, or sated, tired or active across the 24 hour clock. Often, we don’t realize the rhythms in our body, it seems to be from the autonomous nervous system. Anything that adapts to temperature changes and dark or light changes in our environment, all possess a natural cyclical rhythm.
- Human needs about 6-7 hours of sleep to reset the body’s function.
- Only human wants to delay or abort the sleep cycle, other animals and plants do not just follow their natural sleep and wake up cycle.
- Circadian rhythm allows us to preserve our internal representation of our outside world so that we can sync our own survival behaviors to match with the external events. Our body maintains a cyclical rhythm for when to release hormone level, feeling active, sleepy, hungry, or exhausted or tired.
Sleep irregularity significantly affects Pain
Surprisingly, chronic pain also has its circadian rhythm, some of us perceive more pain in the morning and others feel a lot more pain in the evening hours. We also can be affected by weather and temperature. Some of us do not like a cloudy windy day because we can feel that chronic back pain is moving lower and more severe. Circadian patterns in pain can be thought of as the changes of hypothalamic pituitary adrenal axis and its cortisol output along with changes in the hormone of melatonin in the evening. Melatonin is the most important sleep inducing hormone.
So pain and sleep are interrelated. Pain disrupts sleep, causes less sleep, prevents long and deep sleep process. In fact, in recent researches, sleep does have a much more effect on pain than pain has effect on sleep. Sleep disruption is much more the real cause of increase pain. The good news is human can have more control of sleep than we think we are.
So managing sleep is consequential in the pain management. If you miss sleep, your tolerance of pain is lower immediately the next morning and your feeling of pain is substantially increased.
