2 hours agoOne dangerous habit you do before bed could actually be doing a lot more harm to your body than you realise – falling asleep with the TV on. However, brain health expert Lev Fomchenkoc has warned that going to sleep with the TV can actually cause huge health problems including memory decline, mood changes, and reduced cognitive performance. The blue light stops your brain from producing melatonin, the sleep hormone that makes you feel tired. When blue light interferes with this process, you’re not only delaying sleep, but also fragmenting the deep sleep phases where your brain does its most important repair work,” Fomchenkoc added. Even though your body might be asleep, your brain is still working to process the constant sound coming from the TV.
