Sleep in Calgary: Long Days, Sleep Studies

In short

Calgary sits at 51°N: the sun sets after 9:50 pm in June and before 4:40 pm in December. Sleep studies ordered by a physician are generally covered by Alberta Health Care, with the Foothills Medical Centre Sleep Centre as the main academic public centre (over 1,600 referrals a year). CPAP is not covered by Alberta Health for most residents. Health Link (811) is the advice line.

Longest day about 16.6 hours (Mid-June), shortest about 7.9 hours (Mid-December) — a swing of 8.7 hours. Clocks change twice a year (second Sunday in March, first Sunday in November).

Your body clock is set mainly by morning light, so the shape of these bars is the shape of your year: a 8.7-hour swing between the longest and shortest days changes when you feel sleepy, how easily you wake, and — for many people — mood. The guides below explain what to do with that.

What is different about sleeping in Calgary

Calgary’s summer evenings are famously long — light until nearly 10 pm in June — which is wonderful for patios and hard on bedtimes, especially for children and for anyone trying to fall asleep before 11. Blackout blinds are not a luxury here.

Winter brings the opposite: under eight hours of daylight in December, though Calgary’s dry, sunny climate means the light that does exist is bright. Ten minutes outside at lunchtime is worth more than an hour by a window.

Shift work is common across the energy sector, healthcare and transport. If you rotate shifts, the shift-work guide covers anchor sleep, light timing and the drive home — which matters on Calgary’s winter roads.

Getting a sleep study in Calgary

The rules are set at the provincial level. In short: In Alberta, a sleep study ordered by a physician for a medical reason is generally covered by the Alberta Health Care Insurance Plan (AHCIP), with the level of coverage depending on the type of test and whether the facility is enrolled with Alberta Health Services. CPAP therapy is not covered by Alberta Health for most residents; funding is limited to programs such as Income Support, AISH, and — for severe sleep-disordered breathing — Alberta Aids to Daily Living.
