Before you optimise your sleep, make sure you’ve got the foundations right.
Good sleep isn’t simply about the number of hours you spend in bed. Duration, regularity and timing all play a role.
For most adults, 7-9 hours of sleep per night is a useful general guide, although individual sleep needs vary.
It’s also worth looking beyond your sleep tracker. If you’re regularly struggling to wake, feeling sleepy during the day, finding it difficult to concentrate or relying heavily on caffeine to get through the day, it may be worth looking more closely at your sleep.
Consistency matters too. Keeping your sleep and wake times reasonably regular can help support your body’s sleep-wake rhythm.
Before adding another device, supplement or sleep intervention, ask yourself:
Am I giving myself enough time to sleep?
Is my sleep-wake schedule reasonably consistent?
Am I supporting my body clock with appropriate light and daily routines?
The basics aren’t always the most exciting part of health optimisation, but they’re often the place to start.
Get the foundations right. Then personalise.
If persistent sleep difficulties are affecting your health, wellbeing or daytime functioning, speak with your GP or an appropriately qualified healthcare professional.
