Sleep

Sleep is a naturally recurring state of mind characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but is more easily reversed than the state of hibernation or of being comatose. Mammalian sleep occurs in repeating periods, in which the body alternates between two highly distinct modes known as non-REM and REM sleep. REM stands for "rapid eye movement" but involves many other aspects including virtual paralysis of the body.

During sleep, most systems in an animal are in an anabolic state, building up the immune, nervous, skeletal, and muscular systems. Sleep in non-human animals is observed in mammals, birds, reptiles, amphibians, and fish, and, in some form, in insects and even in simpler animals such as nematodes. The internal circadian clock promotes sleep daily at night in diurnal species (such as humans) and in the day in nocturnal organisms (such as rodents). However, sleep patterns vary widely among animals and among different individual humans. Industrialization and artificial light have substantially altered human sleep habits in the last 100 years.

Sam Harris

Samuel Benjamin "Sam" Harris (born April 9, 1967) is an American author, philosopher, and neuroscientist. Harris is the co-founder and chief executive of Project Reason, a non-profit organization that promotes science and secularism, and host of the podcast: Waking Up with Sam Harris. As an author, he wrote the book The End of Faith, which was published in 2004 and appeared on The New York Times Best Seller list for 33 weeks. The book also won the PEN/Martha Albrand Award for First Nonfiction in 2005. In 2006, Harris published the book Letter to a Christian Nation as a response to criticism of The End of Faith. This work was followed by The Moral Landscape, published in 2010, in which Harris argues that science can help answer moral problems and can aid the facilitation of human well-being. He subsequently published a long-form essay Lying in 2011, the short book Free Will in 2012, Waking Up: A Guide to Spirituality Without Religion in 2014 and Islam and the Future of Tolerance: A Dialogue in 2015.
