It is the start of BST, which means that the clocks have changed again 🌜🌑🌛
Evidence is showing that this means so much more than just an hour less in bed. Recent studies suggest that this twice-yearly schedule shift can have a detrimental impact on our health.
We all have a body clock inside of us which follows a natural rhythm (our circadian rhythm). This rhythm shapes physical, mental and behavioural changes in us that follow a 24-hour cycle, and it regulates things like alertness, sleepiness, appetite and mood.
Shifting our sleep/wake times by as little as one hour on an ongoing basis, can have a dramatic impact on our circadian rhythm, and can result in low energy levels, disrupted sleep, dysregulated appetite, and wildly fluctuating or low mood.
To top it all off, recent studies show that disruption to habitual sleep patterns also has a profound effect on cardiovascular health.
What can you do if you find yourself impacted by the clock change?
🌞 The main thing you can do is make sure you get some exposure to natural light every day. Our circadian rhythms are highly influenced by this. Try to get outside every morning, as early as you can after you get up and aim to get 20-30 mins of light exposure. For an even more impactful light prescription, try to get out for a similar period of time as dusk approaches too.
🌜 Establishing a standard sleep and wake time and sticking to it can help you to adjust more quickly to the change. Avoiding caffeine and other stimulants past midday, and avoiding electronic light stimulation in the evening can all help you to drop off more easily and get a more restful night.
🌞 Consider layering in some extra self-care strategies for the next few weeks as you adjust to help you regulate your mood more effectively and get better sleep. Breathwork would always be my primary go to for this, because it's simple and easy to incorporate into your schedule.
On the plus side, at least at this time of the year, we get the benefit of increasing daylight hours, which supports our mental health positively.
