Do you find that as you age you get less and less quality sleep? You’re not alone. A study published in Science explains why sleep seems to deteriorate as we age. The study found that “aging correlated with enhanced spontaneous activity of wake-promoting brain areas during sleep” due to the increase in activity of hypocretin-expressing neurons, “raising the chances of brief arousals and thus causing sleep to be more fragmented.” Understanding this will allow for more effective sleep aids and treatments for those of us who are experiencing age-related sleep deterioration.
