I've now done this for 3 mornings. I find joy in listening to all the birds joining in for the dawn chorus.
Also, I've noticed that my mood, sleep & cognitive function has improved a lot.
I sit outside with warm blankets & cup of tea, so I'm comfortable.
For some reason, I have completly made the decision to wake up super early in the morning & sit outside in the cold, just in time to hear the birds go off all at once.
