Sleep deprivation and poor sleep quality.

Sleep deprivation and poor sleep quality affect concentration, memory, and decision-making and can cause feelings of anxiety, irritability, and impulsiveness. To fall asleep faster, stay asleep, and have a better night's sleep overall, build a sleep routine says Dr. Benjamin Smarr, assistant professor at the University of California San Diego specializing in neuroscience and sleep science. "Sleep is very complicated and requires many parts of your brain and body to agree," he said. "So the more familiar your pre-sleep routine is, the more likely all those parts will line up." 

Everyone has little tricks to help them achieve this ideal sleeping state, so I asked the rest of the Business Insider Reviews team to share the products they've built into their nightly routines. 

Unsurprisingly, many of their favorite products directly relate to our best sleep products, including the best pillows and best weighted blankets. Apps and accessories also help our team, whether filling the air with soothing scents and sounds or contributing to overall comfort and coziness.

But if you're experiencing serious sleep disturbances that consistently impact your life, the following solutions may not be adequate, and you should consider consulting a specialist. Dr. Azizi Seixas, an associate professor at the University of Miami Miller School of Medicine whose research focuses on sleep disparities, says, "If these disturbances occur for longer than a month, then the person should seek professional help. Another sign that suggests immediate intervention is needed is if the person feels physically sick as a result of sleep disturbances."
