This video was about using technology before bed.
Sleep works by a part of your brain acting like a clock which detects the brightness of light. When it’s dark your brain tells another part of your body to realise melatonin which makes you sleepy if there is lighter your body reduces the amount of melatonin. it is important to sleep well so we can concentrate learn and remember. I now understand why we should not use technology before bed. I also understand how we sleep and why we need sleep. Who found out that technology interrupts our sleep?
