Taking your smartphone to bed is the best way to end up with insomnia. Smartphones cause insomnia because they are distracting. The sounds and vibrations of calls, notifications, and messages can stop people from sleeping or even wake them from sleep. People who take their phones to bed can also end up checking social media and more, causing them to sleep much later than they intended. If that was not enough, smartphones and almost every other tech gadget with a screen emit a blue light that the brain mistakes for daylight. This causes the brain to lower the secretion of melatonin—the hormone that tells our body it is time for bed. This is usually not a problem during the day but becomes one when we are trying to get some sleep at night. I know it is a mistake, but still, I take it with me to bed every single night. Do you?
