Deep sleep is 1 of the 4 stages of sleep.

It’s critical for performance and longevity. Specifically:

• 💪 Recovery and growth
• 🦠 Immune system function
• 💥 Removing toxins
• 🧠 Memory consolidation
  

Most need 1-2 hours of deep sleep each night.

My sleep tracker tells me I’m on the lower end of that.

Even if the tracker isn’t super accurate, there aren’t many downsides to chasing more deep sleep.

Unsurprisingly it’s the usual stuff that helps (good sleep habits, exercise, diet, stress, etc).

And interestingly there’s emerging research linking fibre intake with deep sleep.

Even if the research isn't conclusive, fibre is elite for our gut health.

In fact, a meta-analysis of over a million people found for every 10g increase in fibre, there’s a 10% reduction in risk of mortality.

We want to aim for at least 30g a day.

We get fibre from foods like fruit, veg, nuts.

Psyllium husk is a cheap and easy way to jack up our intake (you can grab it from the supermarket).

Throw a spoonful in a smoothie, shake or yoghurt.

An easy habit to start for our performance and longevity.
