Light plays a crucial role in regulating our sleep/wake cycles, as our internal body clock is directly influenced by the natural rising and setting of the sun.
This is where our Bodyclock wake-up lights come to the rescue, with their gradual sunrise and fading sunset. Mimicking the subtle light and colour changes of the sun rising and setting, clinical trials have shown that lights such as Bodyclock improve the quality of sleep and awakening.
So, if you are feeling sleepy during the day because you’re struggling with your sleep/wake cycles, a bright light box could really help recharge your batteries. Using bright light therapy in the morning and evening will also cue the feeling of dawn and dusk, helping to further regulate your circadian rhythms.
Try and get some light exposure first thing, or if you can’t get outside, use one of our SAD and energy lights over breakfast. This will push your body clock earlier in time and make it easier to fall asleep. A dawn simulator like Bodyclock that wakes you gently with a gradual sunrise, could also help reset your clock.
Utilising a Bodyclock, where light gently increases to full brightness, could help to reduce the symptoms of sleep inertia (a desire to return to sleep) and gradually awaken, whilst stabilising your body clock at the same time.
It is possible to push your body clock later in time by using a bright light box for 30 min in the early evening finishing at least 1 hour before you want to go to bed.
Use a bright light box in the morning to shift your body clock to an earlier time. Alternatively, you could use a Bodyclock wake-up light to reduce sleep inertia and to help shift your body clock to waking earlier naturally.
An unstable sleep pattern could indicate that your body clock is receiving weak light signals. Using bright light therapy in the morning and evening will cue the feeling of dawn and dusk, helping you to regulate your sleep/wake cycle.
Getting your body to fully adapt to a rapidly changing shift schedule just isn’t possible, due to the fact your internal clock doesn’t instantly reset to a new light/dark cycle.
This means that sleep may be very disrupted when working shifts as your body clock will be completely out of sync. It may be beneficial to use a dawn simulator or a bright light box upon awakening to boost alertness levels and minimise sleep inertia upon awakening.
