Sleep research
Sleep robs us of roughly 1/3 of our lives. With a global population of
7b, this equates to 2,300m Disability Adjusted Life Years (DALYs) per
year. Compare this to cancer which globally
costs 169m
DALYs/year, or cardiovascular disease which
cost 63m
DALY/year. Indeed the entire global cost of all
diseases, 1,500m
DALYs/year, is less than DALYs lost to sleep.
Funding by the NIH for sleep research in FY 2015 amounted
to $233m
out of a total
of $30.3b
for FY 2015 for all diseases, or less than 1%.
8 hours of sleep doesn't don't seem intrinsic to the human condition,
rather it is an evolutionary adaption to the diurnal world (around
which other evolutionary adaptions have doubtless formed). Drugs such
as modafinil suggest that we can readily
get by on 2.5 hours of sleep per night with few serious side effects.
What is called for is more research on why we sleep, the side effects
of taking drugs such as modifinil for prolonged periods of time, and
the development of other similar drugs. What is promised is not,
reducing the time lost to sleep to zero, but to perhaps a less
expensive 2.5 hours a day.
