As someone who regularly only gets 3-4 hours of sleep a night due to schedule, the quality of my sleep is absolutely paramount. Not only do I not function without good, deep, quality sleep, but it affects my mood, my physical recovery from work and working out and my productivity at work and family the next day. Products like this help you naturally fall into a deeper sleep rhythm faster, resulting in more quality sleep, even on less hours. These are an absolute game changer, allowing me to keep my necessary schedule without sacrificing the recovery and recharge from sleep.
