I tend to take a few minutes out of my day to practice meditation/mindfulness in the evening. It helps me wind down before sleeping, reflect on my day, set goals for the next day, and it helps ease any worries/anxieties I may have. I practice mindfulness in two different ways, depending on how much time I have and how I feel. I take into account how stressed I have felt during the day and how my mood at that time is as well. If I am in a bad mood doing intense practice using an app or video helps lift that mood.
The First Way
If I have time or I am feeling particularly anxious, I like to use a mindfulness app (Calm or Headspace are my favourites) or use a YouTube video. I usually do this in bed, so I can go straight to sleep after. I put my headphones in, get comfortable, either lying down or sitting in a comfortable position, choose a practice to listen to, and follow the gentle instructions. I prefer this way as I like the relaxing music they often have in the background as it blocks out any distractions, but if it is a late evening and I feel drained, I prefer to do the method below.
The Second Way
This way is something I have kind of made up myself after doing plenty of mindfulness videos. I do it without the help of an app. I lie in bed, get comfortable, close my eyes and bring my attention to the breath. Blocking out any sounds/activities around me can be a little tricky, but it is definitely possible with a bit of focus. In your head, begin to count to ten, take a deep breath in through the nose. Repeat this as you breathe out through your mouth. Feeling the rise and fall of your chest helps to focus on the practice. I repeat this until I feel completely relaxed.
I hope this helps to give guidance on how to practice a couple of forms of mindfulness. I am no professional by any means, and there is plenty of direction out there through videos and apps such as Calm and Headspace. There are many different ways you can practice mindfulness throughout the day, not just in the evenings; this is just what works best for me.
