The Ramadan Sleep Challenge in Canada
For Canada's 1.8 million Muslims, Ramadan brings a unique sleep challenge that intensifies the further north you live. In Brantford and southern Ontario, spring Ramadan means fasting windows of 14 to 16 hours. Suhoor (the pre-dawn meal) must be completed before fajr prayer, around 4:30 to 5:00 a.m. Iftar (the evening meal) comes at sunset, around 8:00 to 8:30 p.m. in late March. Taraweeh prayers at the mosque often run until 11 p.m. or midnight.
Brad, Owner since 1987: "We have many Muslim customers in Brantford who come in during or just after Ramadan looking for help with sleep The schedule is demanding, especially for people who also work full-time. A great mattress will not give you extra hours, but it can make every hour of sleep you get count more."
The math is stark: if suhoor wakes you at 4:15 a.m., Taraweeh keeps you at the mosque until 11 p.m., and you need 30 minutes to wind down, your nighttime sleep window is roughly 4.5 hours. That is unsustainable for 30 days without strategic supplementation.
What Research Says About Fasting and Sleep
Fasting itself affects sleep architecture through several mechanisms:
- Circadian rhythm shift: The altered meal timing during Ramadan shifts circadian markers including core body temperature and melatonin secretion. Research in Chronobiology International found that melatonin onset delays by 30 to 60 minutes during Ramadan (Bogdan et al., 2001).
- Dehydration effects: Daytime fluid restriction can lead to mild dehydration by evening, which is associated with increased nighttime awakenings and lighter sleep. A study in the Journal of Sleep Research confirmed that even mild dehydration (1 to 2% body mass) reduces sleep quality (Sawka et al., 2015).
- Meal composition and timing: Heavy iftar meals close to bedtime can cause gastric discomfort and acid reflux that disrupts sleep onset. Research from King Saud University recommends finishing the main iftar meal at least 2 hours before lying down (Roky et al., 2004).
- Caffeine withdrawal: Many people reduce or eliminate caffeine during fasting hours. Caffeine withdrawal symptoms, including headaches and fatigue, peak on days 2 to 4 and can fragment sleep (Juliano and Griffiths, 2004, Psychopharmacology).
The Split Sleep Strategy
Sleep researchers have studied biphasic (two-phase) sleep patterns extensively, and the evidence supports their effectiveness for situations like Ramadan where a single consolidated sleep block is not possible.
Recommended Ramadan split sleep schedule:
- Main sleep block: 11:30 p.m. to 4:00 a.m. (4.5 hours). This captures your deepest slow-wave sleep, which occurs primarily in the first half of the night.
- Supplementary sleep block: 1:00 p.m. to 2:30 p.m. (1.5 hours, one full sleep cycle). If work allows, this block adds critical REM sleep that you miss from the shortened main block.
- Total: 6 hours. Not ideal but sustainable for 30 days with proper sleep hygiene.
Smart Napping During Ramadan
If a 90-minute afternoon nap is not possible due to work, shorter strategic naps still help:
- 20-minute power nap after Dhuhr prayer: Enough to reduce adenosine pressure (sleepiness) without entering deep sleep.
- Post-iftar nap (risky): Some people nap immediately after iftar. This can help if you need to stay up for Taraweeh, but eating a heavy meal and then lying down increases acid reflux risk. Keep it to 20 minutes and elevate your head.
- Weekend recovery: On non-work days, extend your afternoon sleep block to 2 to 3 hours. This does not fully repay sleep debt but prevents it from reaching dangerous levels.

Suhoor Nutrition for Better Sleep
What you eat at suhoor affects both your fasting day and your ability to fall back asleep afterward (if time permits):
- Complex carbohydrates + protein: Oatmeal with eggs, whole wheat toast with nut butter, or yogourt with dates. The tryptophan in protein and the slow-release carbohydrates support sustained energy and, if eaten early enough, can promote drowsiness for a brief post-suhoor rest.
- Hydration: Drink 500 to 750 mL of water at suhoor. Adequate hydration before the fast reduces nighttime awakenings the following night.
- Avoid heavy, spicy, or fried foods: These increase gastric discomfort and make it harder to rest after suhoor.
- Limit caffeine at suhoor: If you drink coffee at suhoor (4 to 5 a.m.), the caffeine will still be active in your system when you try to nap at 1 p.m. (caffeine half-life is 5 to 6 hours). Consider half-caf or skip it entirely during Ramadan.
Sleep Environment Optimization
When your sleep window is compressed, sleep efficiency (the percentage of time in bed actually spent asleep) becomes critical. Every minute of wakefulness in bed represents lost rest you cannot afford.
- Complete darkness: Blackout curtains are essential, especially for the afternoon nap when Ontario spring sunlight is strong.
- Cool temperature: 18 to 19 degrees Celsius. Core body temperature drop is a primary sleep onset trigger.
- Pre-set alarm: Set your suhoor alarm before your main sleep block so you are not anxious about oversleeping. This anxiety alone can delay sleep onset by 15 to 30 minutes.
- Phone on Do Not Disturb: Only your suhoor alarm should be able to wake you. Notifications from group chats (which are often active late during Ramadan) will fragment your already short sleep.
Your Mattress During Ramadan
When you have 4.5 hours for your main sleep, you cannot afford 20 minutes of tossing and turning to find a comfortable position. Your mattress needs to conform to your body immediately.
Brad, Owner since 1987: "During Ramadan, your mattress is not a luxury, it is a necessity We help families choose mattresses that maximize the sleep they are able to get. That might be the most important health decision you make during the holy month."
Children and Ramadan Sleep
Children are not required to fast before puberty in Islam, but many families involve children in some Ramadan activities including late-night iftars and mosque visits. The Canadian Paediatric Society recommends that school-age children maintain consistent bedtimes during cultural celebrations.
Practical tips for Brantford families:
- Let children participate in early evening iftar but keep them on their regular bedtime schedule.
- Save late Taraweeh visits for weekends when sleep recovery is easier.
- Children who are beginning to fast (typically around age 10 to 12 for partial fasts) need even more attention to sleep, as their developing brains are more sensitive to sleep restriction.
Frequently Asked Questions
How much sleep do people lose during Ramadan?
Research shows Ramadan observers lose an average of 1 to 2 hours of sleep per night due to early suhoor meals and late Taraweeh prayers. Over 30 days, this represents significant cumulative sleep debt that requires strategic napping and sleep hygiene to manage.
Is it okay to split sleep during Ramadan?
Yes. Research from the National University of Singapore found that split sleep (a main block plus a supplementary nap) preserves cognitive function comparably to single-block sleep as long as total sleep reaches at least 6.5 hours over 24 hours. A 4.5-hour main block plus a 1.5-hour afternoon nap is a sustainable Ramadan strategy.
What should I eat at suhoor for better sleep?
Complex carbohydrates with protein (oatmeal with eggs, whole wheat toast with nut butter) provide sustained energy and the tryptophan needed for sleep. Drink 500-750 mL of water. Avoid heavy, spicy, or fried foods. Limit caffeine since its 5-6 hour half-life will interfere with afternoon naps.
Does fasting itself affect sleep quality?
Yes. Fasting alters circadian markers including melatonin onset timing and core body temperature rhythm. Dehydration from daytime fluid restriction can also increase nighttime awakenings. However, these effects are manageable with proper hydration at suhoor and iftar, and strategic sleep scheduling.
How can I nap effectively during Ramadan?
The ideal Ramadan nap is 20 to 90 minutes between 1 and 3 p.m., when your circadian rhythm naturally dips. Use a dark, cool room and set an alarm. If possible, aim for a full 90-minute cycle to capture restorative REM sleep. Even a 20-minute power nap significantly reduces daytime sleepiness.
