In modern society, one reason for not being able to sleep is the use of electronics just before going to bed. This is psychologically and physically stimulating in such a way that adversely affects your sleep. Whether you’re playing a video game or checking the weather or emails, using a cellphone in bed could delay your sleep. All electronic devices such as TVs, smartphones, tablets or laptops affect your circadian rhythms.
The release of melatonin, the sleep-inducing hormone, is suppressed. This is mostly due to the artificial blue light that these devices emit. The more electronic devices used before bedtime, the harder it becomes to fall asleep. Alertness is increased at a time when you should be starting to feel sleepy. Further studies on light emissions from screens are currently being done, so more answers on exactly how they affect sleep should be forthcoming.
Another factor that affects sleep is that these devices hold your attention and keep your brain engaged at a time when you should be winding down for the night. In combination with the excessive blue light exposure, it’s no wonder that your brain feels stimulated and alert instead of pleasantly relaxed and sleepy.
Try to turn off all electronic devices at least half an hour before bedtime. The earlier in the evening this is done, the better but keep to whatever feels realistic. Reading a book in bed is a good substitute for being on a cell phone prior to going to sleep. Studies have revealed that texting late at night affects a teenager’s quality of sleep and grades. It may be helpful to establish an electronic gadget curfew for the whole family.
