The sleepless and wake up to depression link:
We have been fed with stories of heroes who slept very little and changed the world over our growing up years…. we say Bunkum!
Our internal body clock regulator called circadian rhythm, (wonderfully tuned by human evolution and nature’s shifts) keeps our bodies in sync with our sleep and wake up cycles in tune with sunrise and sunset cycles.
Studies have revealed beyond doubt that an out of sync body clock could be linked to depression.
Newer studies suggest that an interrupted circadian rhythm can also increase the risk of mental disorders like depression, bipolar disorder, and other mood disorders. With our current lifestyles, increased activity at night and decreased activity during the day result in a disrupted circadian rhythm.
Disrupted sleep routine cases are more susceptible to mood disorders. They are prone to have decreased feelings of well being and reduced cognitive functioning. Biological clocks are the organism’s internal timing device. They are composed of specific proteins that interact in cells throughout the body. Our biological clocks produce circadian rhythms and regulate their timing. Circadian rhythms determine nearly every biological process in our bodies which includes sleeping, hormone release, body temperature and even regulating our immune systems.
It also determines our chronotype which is the actual duration of sleep every 24 hours.
Whilst internal factors within the body produce circadian rhythms, signals from the environment also affect them. The main causative factor influencing the circadian rhythms is daylight. This light can turn on or off genes that control biological clocks. Changing the light-dark cycles can speed up, slow down or reset circadian rhythms. Biological clocks that run too fast or too slow result in disrupted circadian rhythms. Irregular rhythms have been linked to various chronic health conditions.
One of the major reasons for obesity and diabetes is associated with abnormal circadian rhythms and have also been linked to various sleep disorders such as insomnia. Biological clocks are found in nearly every tissue and organ. Many of the clock genes and proteins are similar across species. Study of the clock components of organisms like fruit flies, mold and mice, research has made important inferences about human circadian processes.
Understanding our biological clocks better could lead to treatments for various health problems in the near future.
Key takeaway: Mothers knew best when to pack off the kids to bed and tuck them in …before noisy news channels and binge TV intruded into our homes. That said, take charge put that tv off, and regulate your sleep schedules with utmost priority.
