Sleep is an important physiological function. Sleep is when our brain replenishes it's neurotransmitters. If you don't get quality sleep, then you don't function well the next day. Sleep deprivation affects not only our physical wellbeing, but also our mental health. Chronic sleep deprivation affects our moods and our memory. Prescription sleep medications can help, but can cause next day sedation and long term dependency and abuse issues. I recommend melatonin as a natural sleep aide that will give you restorative sleep. Try Natrol melatonin supplement and start getting a good night's sleep!
