If you use a tablet like the iPad or Android device, you might not have a great night's rest. Why? According to researches, the light that is transmitted could trick the brain into thinking it's daytime. According to the Daily Mail:

That is because this type of light mimics daylight, convincing the brain that it is still daytime.

Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours.

By contrast, light which is more orange or red in tone does not suppress melatonin production, perhaps because our brains recognise it as a cue that the day is ending.

Neurologists have known for years that staring at screens late in the evening can disrupt sleep - be they television screens, computer screens or mobile phone screens.

However, because mobiles and tablets are by nature portable - not to say addictive - more people are taking them into the bedroom.

Have you noticed that your sleep has been getting worse if you take a tablet into the bedroom? Do you think it's a good idea to bring tablets into the bedroom? Personally, I haven't noticed any difference in my sleep but who knows.
