Your iPad could be causing you serious sleep problems and you may not know it especially if you watch movies or surf the web on your tablet before bedtime.

A study by the Lighting Research Center at Rensselaer Polytechnic Institute in upstate New York says under regular conditions, the hormone melatonin signals the body that it is night and helps make you drowsy and you fall asleep.

 However the research shows that an iPad set at maximum brightness for at least two hours suppresses the normal night-time release of melatonin which is a crucial hormone in the body's clock, also known as the circadian system in effect delaying your sleep.

 Longterm, over many years, it could lead to a disruption of the circadian system and result in serious health complications, according to the study published in Scientific American.

The scientists expressed hope that the next generation of tablets will be more 'circadian friendly.' One possible answer is adding a feature that would allow the user to switch to white text on a black screen at night so as to limit the exposure to light.

In the meantime, tablet users are advised to turn down the brightness on their devices before bed, or better yet, turn them off altogether.
