Sleep deprivation is extremely dangerous for brain, scientific research found


“We show for the first time that portions of synapses are literally eaten by astrocytes because of sleep loss,” researcher Michele Bellesi said. Increased microglial activity has been linked to many brain disorders, including Alzheimer’s disease. Astrocytic phagocytosis of synaptic elements shows a further significant increase after prolonged and severe sleep loss. Without any doubts, this is a serious warning. The National Sleep Foundation has even updated its recommended hours of sleep as a guide to keep everyone safe. So how much sleep is enough sleep ? Newborns and infants should have about 12 to 17 hours of sleep. Toddlers and preschoolers need approximately 10 to 14 hours of sleep. School age children from 6-13 years old need about at least nine hours of sleep while teenagers up to 17 years old should get between 8 and 10 hours. Younger adults aged 18 to 25 and adults aged 26-64 need about seven to nine hours of sleep and older adults who are 65 years old and above require seven to eight hours of sleep. Take care for yourself !
