I remember a trip to Thailand in which I didn’t sleep all night long. It is often like that for people when they travel. So why is it we often don’t sleep well when we are not in our own homes? Scientists think they have the answer.
Researchers at Brown University looked into this phenomena and found that the left hemisphere of the brain stayed more active and awake during “slow wave” sleep on that first night away from home. In effect the left hemisphere”kept an eye open” during the night during that first night and scientists believe this activity is used as a sort of protective device.
Researchers noted this and began to electrically stimulated that part of the brain and noted that subjects where quicker to wake and get up when this stimulation occurred to the left hemisphere vs. the right on this first night.
Many follow up studies are planned and in the future it is hoped that the researchers will actually find a way to let us weary travelers sleep just a little better. Wouldn’t that be a dream!
