Since the epoch-making observations of circadian rhythm in
Mimosaceae plants, sleep has been investigated for centuries
(de Mairan, 1729; Du Monceau, 1758). As a natural and
reversible state, sleep is marked by reduced responsiveness
to
external
stimuli,
relative
inactivity,
and
loss
of
consciousness. Although reduced responsiveness could
potentially introduce significant danger to survival, nearly all
animals in nature sleep. This strongly implies an adaptive role
of sleep in increasing overall fitness of an organism. Research
has shown that sleep is responsible for many vital
physiological functions, including tissue repair (Oswald, 1980),
skin
function
(Rechtschaffen,
1998),
thermoregulation
(Parmeggiani, 1986; Rechtschaffen, 1998), energy saving
(Siegel, 2005), insulin release and responsiveness (Spiegel et
al., 1999), metabolic regulation (Sharma & Kavuru, 2010),
immunological enhancement (Besedovsky et al., 2012; Imeri &
Opp, 2009), synaptic plasticity (Benington & Frank, 2003),
neuron viability (Zhang et al., 2014a), and memory formation
(Rasch & Born, 2013; Walker & Stickgold, 2006). Sleep
therefore plays an essential role in human health and is vital
for physical and psychological performance (Halson & Juliff,
2017; Thun et al., 2015; Vitale & Weydahl, 2017).
