If you didn't sleep well the night before, you've probably experienced symptoms like irritability and poor concentration. In the long-term, poor sleep quality is also linked to adverse physical health conditions. It helps to create a bedtime routine and an optimal environment to fall asleep and stay asleep. As I learned from my Insider Reviews colleagues, this environment can include products like a weighted blanket (or its smaller relative, the weighted eye mask), comfortable sleepwear, and a good old-fashioned bedtime story.
