The National Sleep Foundation claims two-thirds of Americans are losing sleep due to late-night use of electronic devices like PCs, televisions and cell phones:
According to Reuters, 95 percent of Americans participating in the study use an electronic device within an hour of going to bed. This is problematic because the use of most technological devices increases alertness and stimulates the brain. In addition, the artificial light from the screens of these gadgets suppress the release of the sleep-promoting hormone melatonin. This has led to sleep deprivation in two-thirds of Americans.
The Sleep in America poll shows that the most sleep deprived age group are those ages 13 to 18, who stay up late at night texting before falling asleep. More than half of kids in this age group text an hour before bed most nights, and report an average of seven hours and 26 minutes of sleep per night. Sleep researchers suggest a minimum of nine hours and 15 minutes.
