Posted on April 11th, 2018
You may already be aware of the effects of sleep deprivation on your health and happiness. While the effects can be subtle at first, you may eventually notice increased impulsiveness, difficulty concentrating, weight gain or chronic pain. When you don’t get enough rest, life becomes a struggle. If you struggle to turn off your brain and fall asleep, you may have already tried some of the many recommended sleep solutions.
