Blue lights from cell phones, computers, overhead lights etc. does the following:

  • Causes your body to produce sugar (called up regulating carbohydrate metabolism)
  • Takes calcium from your bones
  • Dehydrates you
  • Ruins your sleep by affecting your melatonin
  • Adversely affects your CRITICAL circadian rhythm

How To

Blocking artificial light from your eyes from screens is the highest priority, but from your skin as well.

  • Do not sit next to or under a strong light before bedtime. That literally makes you pre-diabetic and compounds with any carbohydrates that you’re eating already.
  • Receive sunlight in your naked eyes first thing in the morning to begin melatonin production in your eyes that promotes melatonin production in the pineal gland.
  • Gym outside or, if you can, turn of the lights and use natural light in which to work out
  • Turn off the lights in your home and office whenever you can and use natural light – saves a few bucks too
  • Limit cell phone, computer and gadget use – especially before bed.  Take regular breaks if you have to work at a computer for long periods
  • Use a blue light filter and or glasses


The benefits of direct sunlight (no sun cream) and or Vitamin D supplements are widely written about… and make sense.  Those reading this with children know that pediatric doctors tell you get your newborn out in the sun… so why stop?  I am not advocating extended periods in direct sunlight or any experience that will lead to getting sunburn however the benefits of direct sunlight include –

  • Lowers blood pressure
  • Improves brain function
  • Improves bone health
  • Enhances the immune system (and therefore by reasoning actually reduces your likelihood of cancers and other diseases)
  • Improves sleep

I indicated on my how page that to me your gut feel matters and for this I personally think of the days I have in the outdoors and usually out in the sun… feel better or worse at the end of the day?

How To

I live in a tropical country and so have a few times a day out in the sun for a few minutes at a time… and I try and do this barefoot.  I am aware this is contrary to WHO guidelines so please read the disclaimer and make your own decision.  If you follow these guidelines the darker you are the more time you’ll need.

If you are not able to get sensible amounts of direct sunlight regularly you want to consider Vitamin D supplements.
