In December 2014, a study looking at sleep quality after reading from smartphones and tablets in the evening was reported in The Independent and at the BBC.

The study found the level of sleep hormone melatonin is lowered after using these devices and this has 2 main effects;

  • it takes longer to fall asleep
  • the amount of dream sleep is reduced

The result is tiredness the following morning and difficulty waking up and feeling alert, particularly in teenagers who naturally stay up late and sleep in. Also, there are concerns that exposure to blue light can cause eye strain and fatigue, short-sightedness and even age-related macular degeneration in later life. The iPad, in particular,  has the highest amount of brightness measured in the study.
