A Medical Daily news report shares the helpful and educational facts we learned about sleep in 2014.

According to the AASM, there’s a major difference between quality sleep and the amount of hours slept (obviously quantity). Most adults need at least seven hours of sleep for optimal health and productivity, though this amount will change with age. Meanwhile, getting good sleep is something else entirely. This means avoiding sleep disrupters, such as snoring, undiagnosed sleep disorders, and restless leg syndrome. Basically anything that interrupts your cycles throughout the night.
