Why Australians are sleeping worse—and what to do about it

Ask any Brisbane GP what's changed in their clinic over the past five years, and sleep complaints sit high on the list. Australians are sleeping worse than ever, and the causes are closer to home than many realise.

The culprits are familiar: blue light exposure from phones and laptops late into the evening, the pressure to stay contactable for work, and rising temperatures that make our bedrooms uncomfortably warm. For Brisbane residents, the humidity and heat during our long summer months—lasting well into May—create additional sleep stress that our bodies struggle to regulate.

"Sleep isn't a luxury; it's a cornerstone of wellness," says Dr Sarah Chen, a sleep health advocate who works across South Bank clinics. "But we're treating it like one."

The data backs this up. Recent surveys show one in three Australian adults now report poor sleep quality, up significantly from a decade ago. In Brisbane's fast-paced suburbs like Fortitude Valley and New Farm, where late-night culture and flexible work schedules are the norm, sleep disruption is even more pronounced.

So what works? Experts consistently point to lifestyle adjustments that cost nothing and require only consistency.

Start with your evening routine. Put your phone away by 9 p.m.—at least 90 minutes before bed. The blue light genuinely disrupts melatonin production. If work demands late responses, set an automatic email reply stating you'll respond the next morning.

Move your body earlier in the day. A 20-minute walk through New Farm Park or along the Brisbane River parklands in the morning or early afternoon—not after 6 p.m.—helps regulate your circadian rhythm. Exercise improves sleep quality without the stimulation that evening workouts can cause.

Cool your bedroom deliberately. Brisbane's summer nights can push indoor temperatures above 26°C. A pedestal fan costs $30–50 and makes a measurable difference. If you can, keep your bedroom temperature between 16–18°C for optimal sleep.

Establish a consistent bedtime. Your body thrives on routine. Going to bed and waking at the same time—even on weekends—strengthens your internal sleep clock.

Watch your caffeine window. Cut off caffeine by 2 p.m. That 3 p.m. coffee from your local South Bank café might feel necessary, but it's likely stealing hours of sleep at night.

If poor sleep persists despite these changes, consult your GP. Sleep disorders like sleep apnoea are common and treatable—but only when identified. Your wellness journey can't truly begin until you're rested.
