Does lack of sleep hold you back on the running track? Here’s the research

Is insufficient sleep stopping you from achieving your true fitness potential? Sleep longer, run faster.

We all need our sleep. Personally, I feel a lot better after getting a full night’s rest, and I’m not yawning my way through the day. Researchers have found that a lack of sleep increases your risk of a range of conditions, including depression, diabetes, high blood pressure, stroke, and heart attack. All the more reason to prioritize your sleep.

I know I’m not functioning at my best if I haven’t got enough shut eye, so I certainly wouldn’t be trying to run a marathon or anything on those days. Research shows that runners who sleep less hours actually do take longer to cross that finish line, highlighting a connection between running performance and sleep.

How sleep deprivation affects running performance

Sleep deprivation slows down your reaction time and impairs brain functioning, so it feels a lot more challenging to finish that run. 

Sprinting

An interesting study concluded that after extended sleep, athletes notably increased their speed and were able to sprint faster. Basketball players had better shooting accuracy with their free throw percentage increasing by 9%. To add to that, the athletes were less fatigued and they reported improved overall ratings of mental and physical well-being during games and practices.

High-intensity training takes a hit

Not getting enough rest also negatively impacts high-intensity training. For example, research reveals that male athletes ran slower sprints when they didn’t get enough rest. Their heart rates were also higher and they breathed faster while doing these intense workouts on insufficient sleep.

Long-distance running

If you can’t handle sprinting or short bouts of exercise after limited sleep, long-distance running and exercises lasting more than 30 minutes might be even tougher. In one study, runners performed 30-minute treadmill sessions at their usual pace. The researchers found the following results when the runners had poor sleep:

  • There was more lactate build-up during steady-state exercises.
  • They were only able to cover shorter distances.
  • Running felt more difficult during long distances.

Concluding thoughts

Research is mounting showing that a lack of sleep will hold you back from maximizing your fitness potential. Poor sleep negatively affects your pace, performance, tiredness, sense of well-being, and more. If you’re planning on going running or working out within 2-4 hours before bedtime, it might be best to stick to moderate intensity. Research shows ultra-endurance runners had better sleep efficiency after moderate-intensity runs compared to higher-intensity runs. Try to wind down and avoid moderate activities within an hour of bedtime.

Lots of elite runners recommend including certain proven practices in your bedtime routine to help you relax and unwind, such as using foam rollers or massagers, taking a hot bath, reading, and doing other calming activities.

Why Peloton’s Kirsten Ferguson takes an hour for herself — and you should too
Kirsten Ferguson on using movement to heal
Kirsten Ferguson

In the hustle of daily life, it’s easy to think of fitness only in terms of physical results — chasing muscle tone, weight loss, or personal records. But for Peloton instructor Kirsten Ferguson, working out is just as much about mental strength as it is about physical gains. I had a conversation with Kirsten to talk about how movement, even in its simplest form, can be a lifeline for emotional well-being.

Through her Peloton classes, Kirsten encourages people to carve out time just for themselves, something she practices daily. In our conversation, she opened up about why she dedicates one hour every day to herself, how to reframe exercise as self-care, and how parents can work through the guilt of taking that time. Whether it’s a full workout or just a few mindful moments of movement, showing up for yourself can have a profound impact on your mental health.

While many people say running is hard on your joints, others state the opposite. Here at The Manual, we’ve covered many of the proven benefits of running, from improving mood to lowering the risk of heart disease and helping to stabilize blood sugar. We’ve also looked at previous research on running and joint health that concludes regularly running strengthens joints and protects against osteoarthritis later in life.

It’s a common misconception that running is inherently bad for your hips, knees, and bone health. Researchers continue to prove otherwise, with growing research showing that this natural form of movement can be protective against knee arthritis, among other benefits. The advantages of frequent running are abundant. Recently, researchers explored whether running heightens the risk of arthritis. Let’s delve into the new study.

I tried the Google Pixel Watch 3 after years with Apple — here’s what shocked me
What surprised me about this fitness watch
Google Pixel Watch 3

I've always been a fan of Apple products for every device, from my iPhone to my Mac to my Apple Watch. There's something safe about sticking with what you know. Though there's comfort to be found in familiarity, the safe choice isn't necessarily always the best one.

Playing it safe and sticking with what you know also means you might not be aware of what's out there that could be a better fit for your needs. When I stepped outside of my comfort zone to try the Google Pixel Watch 3, I learned a few things. Here's what surprised me most about trying the Google Pixel Watch 3.
