A new Harvard study is re-affirming the assertion that reading light-emitting e-books before bed, like computer tablets, could have a detrimental effect on sleep, which can in turn lead to serious health problems.
You may already be familiar with the suggestions that too much exposure to light, both before and after we go to bed, can be disruptive to our sleep patterns. The problem is that, as diurnal creatures, our bodies respond poorly to suppressed releases of the brain chemical melatonin, which is emitted when we're exposed to darkness. And when we're deprived of sleep, we become prone to some rather serious conditions, including an increased risk of breast cancer, colorectal cancer, and prostate cancer. At the same time, the subsequent triggering of cortisol introduces another set of problems related to body-fat levels, insulin resistance, and systematic inflammation.
What the heck? Note the reference to "light-emitting e-books" only, not e-ink displays, but this still sounds serious.
