Bright Light Confuses Mind

IPad May Cause Insomnia

When used just before going to bed, the new iPad and other glowing gadgets like laptops may confuse the mind enough to think it's daytime. That confusion may result in delayed sleep, reports CNN. The stimulating light may be enough to disrupt your normal circadian rhythm, the brain's sleep clock. CNN reports that since the iPad's light shines directly into your eyes from a close distance, the gadget may be more likely to disrupt sleep than a television located across the room or a lamp that doesn't direct light into the eyes. The blue light coming from phones and laptops may worsen the brain's confusion since blue light is less common during the evening. Rensselaer Polytechnic Institute professor Figueiro suggests wearing sunglasses with orange lenses to block the blue light at night!
