Hypnotic relaxation
This guided relaxation track is free to use, you can listen to it directly from this webpage. The best time to listen is before you go to sleep, it will help you relax and help you improve your sleep.
To add to this experience, I suggest getting yourself into a positive mindset by recounting to yourself all the positives of your day, even better, write them down!
Please note: Do not listen to this whilst driving, operating machinery or any other situation where your full attention is required.
