Surely you have bing-watched your favorite series on Netflix, tucked inside a blanket with a hot cup of chocolate during a lazy weekend. We keep our eyes glued to the computer screen deep into the night, and shift bed time. But then comes Monday, and the body wants to remain inside the same warm blanket. Our body clock shifts and it wants to sleep late, and wake up later. Is there any way to reset the body to normal time? Get it refreshed for the week?
Ellen, Andrew and colleagues from University of Colorado find that exposing the body to natural light is an easy fix for the disrupted body rhythm. They find that spending a weekend under artificial light shifts the body clock to a later period, but that such delay can be prevented by weekend camping under natural sunlight. So to all people who feel the blues on Monday, pitch a tent. To know in detail on this phenomena, please listen to Ellen.
