Sleep is one of the most important pillars of health. 

Our bodies and our brains are designed to function during the day and rest at night.

Circadian rhythms are 24-hour cycles which are kept in time by light and dark cycles.

These rhythms can become disrupted by changing our exposure to light which can affect our sleep and make us feel sluggish during the day. Everything from our immune-system function, our gut function, our muscle strength and our hormones show a daily rhythm.


 

We often think of sleep as the third pillar of health underneath diet and exercise but Matthew believes sleep is the first pillar on which all others sit.
