#7pmSwitchOff – How does Blue Light Affect Sleep?

Light is the most powerful cue for shifting the phase or resetting the time of the circadian clock. In an evening, the blue light that emits from devices (including TVs) suppresses the natural production of melatonin – the hormone you need to feel sleepy – and plays havoc with your body’s circadian rhythms making it harder to fall asleep and stay asleep.” – The Sleep Council

If you’ve been following me for a while you’ll know that I have a social media free day every week (#SwitchOffSundays since summer 2017). I find this incredibly beneficial though for the rest of the week I notice it can be all too easy to slip into the habit of scrolling late in the evenings when I should either be winding down for bed (or already asleep) A great sleep workshop in August with with Tamu from Live Three Sixty and Greg Fearon reaffirmed what I already knew deep down – that I needed to take some steps to improve my sleep routine.

Compared to four/five years ago I definitely see and feel that I cannot take sleep for granted. And even on those days where I think I’ve had a great night’s sleep I can wake up still feeling tired. After keeping a journal to track this I saw that this always happened when I had been on my phone close to bedtime. With this in mind I’ve decided to start switching off from social media at 7pm each day.

If this resonates with you too then why not join me for #7pmSwitchOff.
