Is Working Out Before Bed Bad for You? We Investigate

You already know that exercise delivers plenty of mind and body benefits. Working out reduces stress, boosts your metabolism, and pumps feel-good endorphins and adrenaline throughout your body. However, the very same effects that make exercise so beneficial (like an increased heart rate and body temperature) might also wreak havoc on your sleep if you sweat too close to bedtime. 

So what’s a girl to do if the only chance she gets to work out is after dinner? We went to the experts to find out the pros and cons of a late-night workout.

The Good (and the Bad)

First, the good news: It’s a myth that late-night exercise automatically equals a poor night’s sleep. “Overall, the benefits of regular exercise and the effects of exercise on sleep regulation outweigh most of the potential downsides,” says Mimosa Gordon, a fitness and Pilates expert based in New York City. 

Research backs this up too—a 2011 study found that pre-bedtime workouts are completely fine and won’t interrupt sleep. In other words, if you sleep well and working out close to bedtime is the best timeframe for you, then go for it, says Gordon. 

That said, with most things in health and wellness, it really depends on the individual. “Some people tolerate pre-bedtime workouts well—I do it all of the time,” agrees W. Chris Winter, MD, double board-certified sleep specialist and author of The Sleep Solution: Why Your Sleep Is Broken and How To Fix It. “In fact, for certain populations (e.g. patients with restless legs), it can be very beneficial to exercise before sleep.” 

But for others, pre-bedtime workouts tend to activate and exacerbate sleep-onset insomnia, AKA your ability to fall asleep when you get in bed. Plus, certain workouts are more likely to disrupt your sleep, namely vigorous aerobic exercise, Gordon adds. “Incorporating VO2 maximum efforts, such as sprinting, close to bedtime can elevate adrenaline levels and possibly cause disturbed sleep or wake-ups in the middle of the night.” 

So which workouts should you do before bed? Gordon recommends sticking to light to moderate aerobic exercise, resistance training, or relaxing workouts like yoga, which are more likely to help overall sleep quality.

To ensure a good night of sleep post-workout, consider these tips, too:

 “Nutrition is an important consideration for late-night training,” Gordon says. It’s important to note that if you put in a lot of effort, such as a long endurance run or a heavy weight-training session, you’ll need to refuel before you go to sleep. “Don’t have a big meal, but do take in some calories after a workout that demands it.” Think: a PB&J on whole-wheat bread, cereal and yogurt, or a post-workout smoothie.

Cool Down

Another boon for better sleep is a post-workout shower. After we shower or bathe in warm water, our body temperature takes a dip, and a cooler body temperature helps signal to our body it’s time to sleep, Gordon notes. Also, Winter suggests helping your body stay cool at night by wearing minimal layers to bed, turning down the thermostat, or even investing in a product like the Ooler sleep system that can actively cool you once in bed. All are helpful.

Dim the Lights

Finally, exercise usually happens in a bright environment, which is bad news for inducing sleep. The reason: Darkness signals to your brain that it’s time to release melatonin, the “sleep hormone” that helps us doze off, while bright light suppresses it. Keep your environment as dark as possible if you must work out late at night, Winter suggests, and dim the lights as soon as you get back home.
