It can help, although it won’t fix every type of insomnia. The idea of a sleep routine is to have you go to sleep at roughly the same time every night and to have you engage in a series of relaxing activities at least an hour before bed. Common candidates such as taking a warm shower, listening to some soft music, and taking some CBD for sleep — visit https://vidaoptimacbd.com/collections/cbd-for-sleep if you haven’t heard of the latter.
The purpose of a routine is to calm you down. Too often we go to bed with the stress of a busy day still coursing through our bodies, which can make falling asleep much harder. Stress is part of the human flight or fight instinct, our response to predators, and we find it hard to fall asleep in a state of stress.
That said, there are plenty of cases of insomnia that are caused by issues much deeper than just stress. So while a sleep routine can work and is worth a try, if your sleep problems persist after you implement said routine, you should talk to a sleep specialist.
