Quick Answer: If you are always tired, start with the most fixable causes first: check your sleep hours, improve your sleep environment, cut late caffeine, and drink more water. If these don't help within 2-3 weeks, book a blood panel (thyroid, iron, vitamin D, glucose). If you snore or wake unrefreshed despite adequate sleep, ask about a sleep apnea referral.

Reading Time: 7 minutes
Most guides about being always tired start with a long list of possible causes. This one starts with what to do. The causes are worth understanding, but what most people actually need is a clear sequence of steps -- starting with the most likely and most fixable -- so they can stop being tired rather than just knowing more about why they are tired.
This guide is structured as a practical sequence. Work through it in order. Most people find their answer within the first two steps.
Note: Persistent fatigue that lasts more than 4 weeks or is accompanied by other symptoms should be evaluated by your family doctor. This guide covers the lifestyle and environmental causes that account for the majority of cases.
Start Here: The Honest Sleep Audit
Before anything else, an honest accounting of your actual sleep. Not what you intend to do or think you do -- what you actually do, on average, across the week.
Your Sleep Audit Questions
- How many hours are you actually in bed, asleep? (Not lying awake, not scrolling -- actually asleep.) Most adults need 7-9 hours.
- What time do you go to bed on weekdays? Weekends? A difference of 2+ hours is "social jetlag" and significantly impairs sleep quality.
- Do you wake feeling rested? If you sleep 8 hours and still wake exhausted, it is a quality problem, not a duration problem.
- Do you rely on an alarm to wake you? If you consistently need an alarm and feel terrible when it goes off, you are likely not getting enough sleep.
- Do you fall asleep within 5 minutes of lying down? That is a sign of significant sleep deprivation -- most rested people take 10-20 minutes.
If the audit reveals you are getting 6 hours most nights, that is your answer. Chronic sleep restriction to 6 hours produces impairment equivalent to two days of total sleep deprivation after two weeks, according to research from the University of Pennsylvania. Most people in this state habituate to feeling impaired and lose accurate awareness of how tired they actually are.
The fix: increase time in bed by 30-60 minutes per night and hold a consistent wake time. Do this for 2 weeks before concluding the fatigue has another cause.
Fix the Sleep Environment First
If duration is adequate but quality is poor, the sleeping environment is the next place to look. Environmental factors are often the least obvious and the most fixable.
| Factor | Optimal Range | Quick Fix |
|---|---|---|
| Room temperature | 16-19°C (61-67°F) | Lower thermostat, lighter bedding, open window in summer |
| Light | Completely dark | Blackout curtains or sleep mask; turn phone face down |
| Noise | Below 40 dB (quiet room level) | Earplugs or white noise machine |
| Humidity | 40-50% | Cool-mist humidifier in winter |
| Mattress comfort | No pain, no pressure points on waking | Assess if you wake with stiffness or need to reposition frequently |
The mattress factor is worth pausing on. An unsupportive or uncomfortable mattress causes micro-arousals through the night -- brief partial wakenings that fragment sleep architecture without fully waking the sleeper. The person wakes feeling tired but cannot identify why, because they have no memory of waking. If you regularly wake with back, hip, or shoulder soreness, or if you and your partner both feel worse in the morning than you did before you had your current mattress, this is worth investigating.
Brad, Owner at Mattress Miracle (since 1997): "When a customer comes in saying they're tired all the time and they've had their mattress for 12 years, I always ask: do you feel better on holiday? When you sleep somewhere else? If the answer is yes, that tells you something. The mattress is usually part of the story. I've seen customers come back genuinely surprised at how different they feel after a few weeks on a properly matched mattress. Not cured of everything -- but noticeably better."
We carry a range of mattresses at our Brantford showroom that can be tried in person. Our team includes Dorothy, our sleep specialist, who helps customers match mattress firmness and support to their sleeping position and body type.
Daytime Habits That Cause Night Fatigue
Several common habits during the day directly undermine sleep quality at night -- creating a cycle where bad sleep leads to compensatory behaviours that make sleep worse.
The Caffeine-Fatigue Loop
Caffeine has a half-life of 5-7 hours in most adults (longer in slow metabolisers, shorter in fast metabolisers, affected by hormonal contraceptives and certain medications). A 3 p.m. coffee still has 50% of its caffeine content at 8-10 p.m. This does not always prevent sleep onset, but it can suppress deep sleep and REM. Reduced sleep quality leads to greater fatigue the next day, which leads to more caffeine to compensate, which leads to worse sleep quality. Cutting caffeine after noon for 2 weeks is a reliable way to test whether this loop is contributing to your fatigue.
Other daytime habits worth examining:
- Alcohol in the evening: Alcohol is sedating but disrupts sleep architecture. It suppresses REM in the first half of the night. You wake having technically slept, but without the restorative REM that helps you feel rested.
- No physical activity: Sedentary people consistently report more fatigue in studies -- not because they need to rest, but because physical inactivity reduces the quality of sleep that night. Even a 20-minute walk most days makes a measurable difference to sleep depth.
- Late and heavy meals: Eating a large meal within 2-3 hours of bed activates digestion and raises core body temperature, both of which impede sleep onset and quality.
- Screen use before bed: Blue light from phones, tablets, and televisions suppresses melatonin. A dimmer evening (low-blue lighting, screen break 1 hour before bed) allows melatonin to rise naturally.
When to Get Blood Tests
If you have genuinely addressed sleep duration, environment, and the common daytime habit issues for 2-3 weeks and still feel always tired, a blood panel is the sensible next step. This is a straightforward request to make of your family doctor and can rule out or confirm the most common medical causes in one visit.
Ask Your Doctor for These Tests
Request: CBC (complete blood count -- checks for anaemia), TSH and T4 (thyroid function), 25-OH Vitamin D (vitamin D level), fasting glucose and HbA1c (blood sugar), ferritin (iron stores -- can be low even when standard iron tests look normal), and B12. These together cover the vast majority of medical causes of unexplained fatigue. Most are routine and covered under provincial health plans in Ontario.
Vitamin D deficiency is particularly common in Ontario. From October through March, the sun angle is too low for UVB to trigger skin synthesis of vitamin D. Most Ontarians develop some degree of deficiency over winter. Fatigue, low mood, and impaired immune function are the most common symptoms. Supplementation (typically 1,000-2,000 IU daily -- confirm with your doctor) is inexpensive and fast-acting.
The Sleep Apnea Checklist
Obstructive sleep apnea (OSA) is estimated to affect 1 in 4 Canadian adults over 30, and the majority are undiagnosed. OSA causes the airway to collapse repeatedly during sleep, producing micro-awakenings that the sleeper does not remember. The result: you spend 8 hours in bed but get almost none of the deep or REM sleep you need. You wake feeling like you have not slept.
Sleep Apnea Risk Factors (Talk to Your Doctor If You Have 3 or More)
- You or a bed partner reports snoring most nights
- A bed partner has observed you stop breathing or gasp during sleep
- You regularly wake with a headache
- You have a dry or sore throat most mornings despite good hydration
- You feel exhausted despite 7-9 hours in bed
- You are overweight (BMI over 30 -- a significant risk factor)
- You have a large neck circumference (over 40 cm for women, over 43 cm for men)
- You fall asleep easily in the day (in meetings, watching TV, as a passenger in a car)
If you have 3 or more of the above, ask your doctor for a sleep apnea referral. A home sleep test is now widely available in Ontario -- you no longer need to spend a night in a sleep lab for the initial assessment. Sleep apnea is highly treatable (CPAP, oral devices, or positional therapy depending on severity), and treatment often produces dramatic improvements in daytime energy within weeks.
A Two-Week Fatigue Action Plan
| Week | Focus | Specific Actions |
|---|---|---|
| Week 1, Days 1-3 | Sleep audit + environment | Check room temperature (lower to 18°C if needed), blackout curtains, no caffeine after noon |
| Week 1, Days 4-7 | Consistency + hydration | Set consistent wake time (same on weekends), aim for 7.5-8 hours in bed, 2L+ water daily |
| Week 2, Days 8-10 | Activity + evening habits | 20-minute walk daily, no screens 45 min before bed, no alcohol on weeknights |
| Week 2, Days 11-14 | Assess + decide next step | Still tired? Book doctor appointment: blood panel + sleep apnea discussion |
In Brantford and Area: Winter Fatigue Is Real
Ontario winters from November through March reduce natural light dramatically. Brantford's latitude means short daylight hours, often overcast skies, and significantly reduced outdoor activity for most people. This combination -- less light exposure, lower vitamin D, less physical movement, and heated dry air -- creates real seasonal fatigue for many residents. If your tiredness is distinctly worse in winter, addressing these environmental factors specifically (morning bright light exposure, vitamin D, humidifier, maintaining activity despite weather) is as important as the general fatigue steps above.

What should I do first if I am always tired?
Start with the most fixable causes: ensure you are getting 7-9 hours of actual sleep per night, check your bedroom temperature (should be 16-19°C), eliminate caffeine after noon for 2 weeks, and increase water intake. If you address these consistently for 2-3 weeks and fatigue persists, book a blood panel with your doctor covering thyroid, iron (ferritin), vitamin D, and blood glucose.
How do I know if my tiredness is from sleep apnea?
Key signs: you snore, a partner has observed you stop breathing or gasp, you wake with morning headaches or dry mouth, and you feel unrefreshed despite 7-9 hours in bed. If you have 3 or more of these, ask your family doctor for a sleep apnea referral. Home sleep tests are now available in Ontario and do not require an overnight hospital stay.
Could my mattress be making me always tired?
Yes. An uncomfortable mattress causes micro-awakenings that fragment deep and REM sleep without fully waking you. If you regularly wake with pain or stiffness, need to reposition frequently through the night, or feel better sleeping elsewhere, your mattress is likely contributing. Mattress Miracle at 441½ West Street, Brantford, can help you assess and find a better match.
How long does it take to recover from chronic sleep deprivation?
Partial recovery from mild-to-moderate sleep deprivation can occur with 2-3 nights of adequate sleep, but full cognitive and physical recovery from chronic deprivation takes longer -- typically 1-3 weeks of consistently good sleep. Do not expect results in 2-3 days if the deficit has been building for months.
When should I see a doctor about being always tired?
See a doctor if fatigue has persisted for more than 4 weeks without improvement, if you have additional symptoms (unexplained weight change, fever, swollen glands, persistent low mood, pain), or if fatigue is severe enough to affect work or daily life. A blood panel and discussion of sleep apnea risk are the standard starting point.
