3 Utilize Light
As mentioned, there are many different cues that the body uses to know whether it is time to sleep or not. When trying to ‘hack’ any system, you need to think about all of the different inputs present – and the human body is no different.
This is why it’s important to consider using light as a cue for when to sleep and when not to. The bright light that is in the bluer spectrum, has the effect of waking us up and stimulating the production of cortisol. Blocking this light, on the other hand, can help to encourage the production of melatonin and other sleep hormones.
This is why it’s very important not to look at phone screens, computer games, or other bright lights just before bed. Blue blocking shades can help with this.
