A good nights sleep is always a good thing, Sleep is a time of recovery, rebuilding and to relax. 

What happens to us during sleep?

Well testosterone and other adaptive hormones repair organs, strengthen and rebuild muscles, and rejuvenate body systems. The immune system’s white blood cells kick into high gear, and macrophages and leukocytes multiply rapidly and induce healthy flora to prevail over harmful bacteria. Sleep also activates the release of human growth hormone (HGH), which helps the body burn fat. As you sleep, regions of the brain responsible for emotional and social function are rested so that you can face the day refreshed, a restorative night’s sleep helps the brain solidify weak memories that might otherwise fade over time.

As the daylight starts to recede and night falls upon us its wise to start reducing the use of Electronic gadgets, from computers to televisions to all things digital, emitting blue light, a sustained and vivid hue on the electromagnetic spectrum. For instance a light referencing scale, a candle light burns at 1800K, incandescent indoor light burns at 3000K, ultraviolet sunlight at peak midday intensity burns at 5500K, and the blue light emitted from most computer monitors burns at 6500K! 

Such high levels cause a spike in cortisol, which inhibits sleep, encourages sugar cravings, elevates your hunger hormone, increases insulin production (which promotes fat storage while you sleep), and compromises leptin signalling (which can blunt satiety sensations and hamper fat metabolism

 We know it’s not always possible to reduce digital emitting blue light but we should always be aware of what is throwing us out of balance at night and to try and reduce as much as we can to have that good nights sleep, After all we will be more productive alert and creative for the next day.

If you really do have to be using a device that emits blue light in the evening then you can always try Flux which makes the color of your screen/display adapt to the time of day, warm at night and like sunlight during the day. Click here to find out more.
