Whether you use one of the best sleep trackers or even a particular pillow, everyone is different when it comes to the requirements for a good night's sleep. I've heard it all – listening to heavy metal, having a fan on all night, feet hanging off the edge of the bed – whatever works I guess.
After recently reviewing the Groov-e Serenity, I realised that listening to certain sounds before bed made me feel a lot sleepier than normal. I started relying on it almost every night, especially after a long or stressful day. However, a new addition to my bedside table has recently made an appearance, and now I'm not sure I can go back.
