Your body naturally follows a circadian rhythm of 24 hours. It is like an internal clock, that triggers and maintains your sleep. It is controlled by external factors (light or darkness) and internal ones like chemicals: Adenosine (building the desire of sleep), Melatonin (producing drowsy feelings to signal your body to sleep) and Cortisol (triggering your body to wake up). (World Economic Forum, 2019)
A Harvard study showed the consequences for people on a schedule that gradually shifted the timing of their circadian rhythms. Their blood sugar levels increased, leading to a prediabetic state, and levels of leptin, a hormone that leaves people feeling full after a meal, went down. (Harvard Health Publishing, 2020)
Moreover, blue light at night can mess up skin’s natural circadian rhythm impacting their natural night-time repair process, which can lead to visible signs of ageing, and dark circles under the eyes. (Bazaar, 2020)
Do not fight the signs your body sends you in the evening. When you are tired, go to sleep! Blue light tricks your body into thinking it’s daytime, so be sure that your bedroom is dark and avoid using electronics before bed. You can also use “night modes yellow lights” if your devices are equipped with.
