Recently I found evidence that fasting can harm our sleep.
A small Moroccan study from 2001 found that those fasting for Ramadan took longer to fall asleep during their month of fasting and experienced less of the deep, rejuvenating sleep that our bodies need the most.
It would appear that our eating habits strongly influence our internal biological clocks, which affects our body temperature and sleep health.
Yet more evidence on just how important a healthy diet and lifestyle are when it comes to sleep, then.
