SleepDeprivation-1939 (Photo credit: DonJinTX)

The Therapy Book had another great BLOG on how light affects us.  The BLOG says, “A 2001 study revealed that sleep deprivation could lead to insulin resistance, a risk factor for the development of adult onset diabetes. A 2002 study showed chronic sleep deprivation could decrease immune function and make a person more susceptible to infection.” “high levels of cortisol and its precursor, adrenocorticotropic hormone” can lead to stress and lower our immune systems response. Hormones are epigenetic triggers. They trigger genes in each cell that respond to the stimulus. Sometimes this response is good and healthy and sometimes it’s bad and unhealthy. Our bodies are not trying to make us unhealthy only react to our environment.
