Lights Off, Phone Off
Bright lights and technology play a large part in sleep patterns. The human brain is wired to use the sun to know naturally when it's time to wake up and go to sleep. The increased use of technology, particularly mobile phones, tablets, and laptop computers, is wreaking havoc on internal body clocks.
Melatonin, a chemical produced in the body at the onset of night time, tells the body when it's time to start "shutting down" and getting ready to sleep. When people spend their evenings and bedtime staring at an intensely bright phone screen, their bodies just don't know what to think.
Using your phone before bed can delay your ability to properly fall asleep by up to an hour. An easy tip (or not, depending on how addicted you are to your phone) is to try not to use your phone, tablet, or computer from about an hour before you plan on going to bed. Also, dimming the lights or turning off the television early can also help.
