I found that in order to really unwind, I needed more. I started reading about mindfulness which led me to meditation. This is a practice that teaches you how to live in the moment. That in order to function and do the things we need to do, we need honest time that our minds and bodies can recuperate. Even something as simple as a 5 minute practice in the morning can make a huge difference. I find that I like to meditate right before bed as that's when I have a tendency to think the most. It's a nice way for me to unwind and focus, allowing me to let go of all my thoughts so I can actually get a decent nights sleep. I found that by adding meditation to my nightly ritual, I was able to be much more productive because I had honest time to wind down. Also, mindfulness has transferred to other areas of my life so now I can focus on one task at a time and get it done quicker and with greater success.
Although it might not be for everyone I still suggest you give it try, you might find it actually really helps!
Here is a meditation practice I enjoy listening to before bed. If you try it, let me know what you think.
