Working night shift and/or rotating shifts can make sleeping difficult. I have previously suggested using a sleep mask or blacking out any windows to ensure your bedroom is dark. I also advocate using a fan or white noise machine to help block out noise to aid your rest.
Here is another suggestion: Download a Delta Waves app. Delta Waves aid in achieving deep, restorative sleep.
I have been using this for several months and I have had the best rest in a long time.
Open the app on your phone, tablet or computer and set the volume at the desired level. The app takes care of the rest. Make sure to set your alarm or you may not wake up on time!
