I bring on a D vitamin to help with the happy and replace that vitamin that was previously provided by the sun. I also use an alarm that introduces light into the room to help me to wake up at a good hour, despite the sun not being up! It's definitely important to find the right methods for doing this.
Conversely, on the bed time routine end of things, having a set of steps that is independent of the sunshine is a good way of letting the body know it's time to wind down/go to bed and get sleepy on it's own. I love a warm shower, lotion, listening to a chill podcast or ambient noise, and maybe some lavender in the diffuser, all help me. --Shannon (team member)
