A shot in the dark here. Twice l've noticed that sleeping on a hard surface (e.g. going camping, or sleeping on the same camping mat, but on the hard floor inside a house) has had an earthing effect on me, giving me what feels like a deep refreshing sleep (if sleep is had).
Has anybody tried this? Does it calm your T?
Caveat: l mean sleeping on the hard floor / hard ground, but it must be on a camping mat / yoga mat nonetheless (otherwise you'll just be hurting all night!).
