Meditation can help you sleep better by calming you down before bed. It can help put you into a deeper state of calmness and relaxation by reducing the stress of the passing day.
Meditation helps center you and brings you back to the present moment. This means that it can help you focus more on the now, rather than on what happened that day, or what may happen in the future. It can help reduce stress, anxiety, pressure, and other negative feelings and emotions.
For many people, these are the exact reasons why they are not getting a good night's sleep, and since mediation can help with those issue, it can be a great way to prepare yourself for bed, and a great way to end the day.
