So to paraphrase – a good sleep hygiene routine is to:
1.) Avoid Blue Screens 1 Hour before Bed
2.) Practise something soothing – Warm Tea, Book, Podcast or Music (Avoid Heavy Metal maybs)
3.) Have a regular routine every night that factors in the hours (7-8) you’ll need in the horizontal position.
4.) Set the temperature and atmosphere in your sleeping palace to be just right!
