It does so both precisely, by creating it hard for people to fall asleep, and obliquely, by inducing the timing of our interior clock and thereby disturbing our favorite time to sleep.

Light stimulate our interior clock over specific light sensor cells in the retina of our eyes. These cells, which inhabit the same space as the rods and cones that create vision viable, inform the brain whether it is a day or night, and our sleep forms are set consequently.

The innovation of the electric light bulb in the late 19th century, we are now revealed to more light at nighttime than we had been revealed all over our evolution. This moderately new pattern of light coverage is nearly convinced to have disturbed our patterns of sleep. Contact to light in the late evening tends to pause the phase of our interior clock and control us to favor later sleep times. Contact to light in the middle of the night can have more capricious effects, but can surely be enough to cause our interior clock to be reset, and may make it hard to return to sleep.

This is likely because our bodies are programmed to react to stressful and potentially dangerous conditions by waking up. Stress, even that caused by daily concerns, can promote this arousal response and make restful sleep more hard to achieve.
