I remember reading an article a few years ago about the potential impact that eating breakfast can have on your sleep quality.
The article was relating the advice of Dr Nerina Ramlakhan (the author of Tired But Wired) who says:
"There are these fallacies swirling around that not eating before bed, or not eating lettuce or tuna, can help you sleep, but it's more crucial that you eat breakfast first thing in the morning, in what I call a 'metabolic window'. It's a timeframe in which you can give your body an important message. It tells it that in your world there is an adequate supply of food, it can relax, and that it can fall into sleep mode when it needs to."
I read the book review in the Independent years ago but thought about it today while eating my breakfast (scrambled eggs, bacon, avocado and tomato, in case you were wondering).
If you're not getting great quality sleep and you skip breakfast, why not try a simple change in eating habits and see if your sleep improves?
