How to Survive the Workday When You‘re Sick, Tired, or Just Not Feeling It

Feeling like you won‘t make it through the day? Read this post before you call it quits.

We‘ve all experienced the dread of dragging ourselves into work when we‘re under the weather, exhausted, or seriously unmotivated. In fact, a recent survey by staffing firm Accountemps found that 74% of professionals admit to frequently going to work tired, with 31% saying it happens "very often."

According to a report by GlobalWebIndex, 80% of internet users suffer the effects of workplace fatigue, with 33% experiencing it regularly. Fatigue at work isn‘t just unpleasant – it‘s unproductive and costly too. The American Productivity Audit estimates that fatigue costs employers $136 billion annually in health-related lost productivity.

While it‘s crucial to stay home and rest when you have a serious illness, more often it‘s a milder case of the "blahs" that we have to push through. As someone who struggles with chronic fatigue on top of a packed work schedule, I‘ve picked up a few strategies over the years for making it to 5pm when I‘m stuck in a fog.

Whether you‘re fighting off the office cold that‘s going around, up all night with a sick kid, or just really not feeling your to-do list today, these tips will help you rally your energy and focus to power through the most important parts of your workday.

1. Prioritize self-care, even when you‘re swamped

When you‘re feeling crummy, it‘s tempting to put your head down and plow through without coming up for air. But neglecting basic human needs like food, water and rest will only tank your energy levels further. No matter how much you have to get done, commit to prioritizing these self-care essentials:

• Aim for 7-9 hours of sleep per night and keep a consistent sleep schedule. A study by the American Academy of Sleep Medicine found that even an hour of sleep debt requires four days to recover performance back to normal levels.
• Set reminders to drink water regularly and aim for at least 2 liters per day. Dehydration causes fatigue, headaches, and difficulty concentrating. Keep a large water bottle visible on your desk.
• Eat balanced meals and snacks every 3-4 hours. Don‘t settle for vending machine fare – pack nourishing, easy-to-digest options like overnight oats, hummus and veggies, or trail mix.
• Get up and walk around every 60-90 minutes, even just to the water cooler and back. Sitting still too long worsens fatigue and brain fog. Set a timer if needed!
• Take mini-breaks to reset with deep breathing, stretching, or a guided meditation app. Research shows taking multiple short breaks replenishes energy and motivation better than a few longer ones.
• If you‘re able to, take a quick 20-minute power nap on your lunch break. NASA found that naps improve alertness by 54% and performance by 34%, with benefits lasting 2-3 hours.

2. Tackle your most important tasks (MITs) first

Mark Twain famously said "If it‘s your job to eat a frog, it‘s best to do it first thing in the morning." He meant that if you have an important task before you, you should tackle it first before anything else. This productivity tactic is even more crucial on low-energy days.

When you‘re trudging through brain fog, you may only have a few quality hours in you. Set yourself up for a sense of accomplishment by knocking out 1-3 MITs early on. Scan your to-do list and ask:

• Which tasks will have the biggest positive impact or negative consequences if left incomplete?
• What absolutely must get done to keep key projects on track and stakeholders happy?
• Which items can only I do or would take too long to explain to someone else?

Once you‘ve identified your MITs, block off focused time first thing to make headway on them before distractions and decision fatigue set in. Save more routine work and meetings for later in the day when your motivation starts to flag.

According to the Pareto Principle, 80% of results tend to come from just 20% of efforts. On days where you‘re running on fumes, investing your energy strategically in high-impact work delivers the best ROI.

3. Communicate proactively with your team

One survey found that more than a third of U.S. workers believe their employer expects them to come to work even when they‘re sick. And according to a study by Robert Half, 57% of workers sometimes go to work sick because they don‘t want to fall behind on assignments.

However, if you‘re truly too sick to be productive (fever, vomiting, dizziness, explosive cough, etc.), the responsible thing is to stay home and rest so you don‘t spread illness or prolong your own recovery. Your team will appreciate you keeping your germs to yourself.

Send a brief email letting key people know you‘re taking a sick day and update your Slack status and voicemail message if applicable. Reassure them that you‘ll be back in action ASAP and ask a colleague to be on point for urgent matters in your absence.

If you‘re toughing it out at reduced capacity, communicate early about what people can expect from you. For example:

• "Hey team, I‘m under the weather so not firing on all cylinders today. I‘ll be prioritizing the presentation for Client X but may need to bump some other items to tomorrow. Let me know if anything is truly urgent and I‘ll do my best!"

• "Hi [manager], I wanted to give you a heads up that I was up all night with a sick kid so I‘m pretty exhausted and foggy today. I‘m going to focus on critical tasks but I may be slower than usual to respond to messages. I‘ll make sure [important item] stays on track!"

Most colleagues will be understanding as long as you‘re upfront about your limitations and don‘t leave them hanging on joint projects.

4. Optimize your environment for productivity

The right surroundings can make the difference between struggling to keep your head up and finding a (fatigued) state of flow. If you can‘t focus in a busy open office today, book a small conference room or see if you can work from home.

Wherever you are, optimize your environment to maximize whatever energy you can muster:

• Aim for good lighting that‘s not too bright or dim. Consider a SAD lamp if you‘re prone to winter doldrums.

• Adjust the thermostat so you‘re not too hot or cold. Research shows the ideal temperature for productivity is around 71.6°F (22°C).

• Use noise-canceling headphones or a white noise machine to block distractions. Let chatty colleagues know you‘re buckling down on something important.

• Clear your desk of clutter, dirty dishes, and visual chaos. Add a cheerful plant or family photo for motivation.

• Stock up on any supplies you might need handy: water, healthy snacks, lip balm, hand sanitizer, a cozy sweater, etc. Wear your comfiest work-appropriate clothes.

5. Harness your natural energy rhythms

Are you a morning person who nods off after lunch? Or do you perk up as the day progresses? Our bodies have natural productivity cycles influenced by sleep patterns, diet, stress, and age.

By tuning into your personal energy ebbs and flows, you can make the most of peak periods and cut yourself some slack during lulls. Try tracking your mood and output for a few days and look for patterns:

• Which hours do you get your best work done? Schedule MITs and focus time then.
• When do you like to collaborate with others or do more social tasks like meetings? Plan those for moderate energy periods.
• What times of day do you consistently slump? Use breaks to rejuvenate and batch low-effort tasks like email catch-up.

On low-energy days, it‘s especially important to ride the waves rather than fighting the current. Work heartily when you‘re in the zone but be ready to switch gears if you feel your focus sliding. Powering through usually just leads to diminishing returns.

6. Pep-talk your way through a tough day

We all know the physical symptoms of being sick or fatigued. But did you know the way you talk to yourself about how you‘re feeling also has a huge impact on your perceived energy levels and motivation?

Researchers have found that positive self-talk improves performance in stressful situations. So instead of internally grumbling "I‘m so useless today" or "There‘s no way I can focus," try reframing with more supportive messages:

• "I‘m doing my best under tough circumstances."
• "I‘m listening to my body and managing my energy wisely."
• "I‘ve gotten through days like this before. I can handle it."
• "I‘m allowed to be gentle with myself. I don‘t have to be perfect."
• "This is temporary. I‘ll feel more like myself again soon."

Treat yourself like you would a good friend who called you up feeling crummy and overwhelmed. Remind yourself that having a low-energy day doesn‘t make you lazy or incompetent. You‘re human and you‘re dealing with a lot! Encouragement and self-compassion will get you a lot farther than beating yourself up.

7. Know when it‘s time to throw in the towel

We‘ve all had those days where we‘re so checked out we read the same sentence 10 times or realize we just poured orange juice in our coffee by mistake. Sometimes despite your best efforts to rally, your body and brain refuse to cooperate and it‘s in your best interest to call it quits.

Signs you should pack it in and rest:

• Severe symptoms like high fever (100.4°F/38°C or higher), difficulty breathing, chest pain, or fainting
• Inability to keep food/liquids down, signs of dehydration
• Dizziness, confusion, or trouble staying awake
• Lack of focus leading to serious errors or safety concerns
• Contagious illness lasting more than a couple days without improvement

If your gut (or a medical professional) says you need a full sick day – or two or three – trust it. Yes, your work is important but your health and wellbeing are even more so. No job is worth ending up in the hospital or taking weeks to recover because you didn‘t take care of yourself upfront.

8. Invest in your long-term wellness and resilience

Powering through an occasional "off" day is admirable and sometimes necessary. But if you find yourself white-knuckling your way through most workdays, it‘s time to take a step back and make a change. Chronic fatigue and illness are often a sign of wider imbalance or burnout.

To build your physical and mental resilience in the long run:

• Prioritize 7-9 hours of sleep per night. Create a wind-down routine to help you shift into relaxation mode.
• Move your body most days, even if it‘s just a 20-minute lunch break stroll. Regular exercise boosts energy and immunity.
• Nourish yourself with mostly whole, unprocessed foods. Studies show diet significantly impacts mood and cognition.
• Find stress outlets like journaling, therapy, meditation apps, or talking to a trusted friend.
• Make time for the people and activities that light you up outside of work. Hobbies and social connection are potent antidotes to burnout.
• Advocate for yourself at work by setting boundaries, saying no when you need to, and taking allotted time off. You can‘t pour from an empty cup!

Finally, if you find yourself constantly battling fatigue, recurring illness, or low mood, don‘t write it off as normal work stress. Check in with your doctor to rule out underlying health conditions like depression, sleep apnea, or hormonal imbalances. These are highly treatable with the right combination of medical support and lifestyle changes.

The bottom line on surviving the workday when you‘re not at 100%

We‘re all human. It‘s okay (and inevitable) to have days where you‘re not your usual energetic, on-top-of-everything self. The goal is to equip yourself with smart strategies for riding out the storm as best you can without compromising your health or drowning in guilt.

The most important thing is to be kind to yourself, ask for help if you need it, and recognize that this too shall pass. Focus on what you can control: staying hydrated, prioritizing rest, pacing your effort, and maintaining a compassionate mindset.

And if you‘re more than just a little bit tired and your tank is chronically running on empty, don‘t ignore the warning signs. Dig deeper to uncover what changes you can make – in your physical health, mental wellbeing, and work-life balance – to feel more energized and resilient in the big picture. You (and your immune system) are worth it.
