You’d assume that the night time after a grueling exercise would convey some well-earned, much-needed deep sleep. However surprisingly, it’s not unusual to have issue falling or staying asleep the night time after a tough session. You may really feel like your physique remains to be buzzing, or that as drained as your physique feels, you simply can’t totally calm down.
It seems, this may very well be an indication that you just’re overdoing it or that your exercise routine may use some tweaking. Right here’s what the consultants say about why you’ll be able to’t sleep post-workout, what it means in your physique, and tips on how to alter your coaching if difficult exercises are resulting in stressed nights.
First issues first: This is how train impacts your sleep
“Train is often superb in your sleep,” says train physiologist and coach Sharon Gam, PhD, CSCS, ACE-HC. Figuring out sometimes improves the time it takes to go to sleep, the variety of instances you get up in the course of the night time, and your complete time asleep—each within the long-term and on the night time that you just’ve exercised.

Gam says train has additionally been discovered to alleviate signs of melancholy and nervousness, that are each linked to sleep issues, and that it helps handle physique composition, which might scale back the danger of sleep problems like sleep apnea.
Train also can scale back daytime sleepiness, says Kathy Nguyen, MD, a main care sports activities drugs doctor at Memorial Hermann Medical Group. “That helps regulate our circadian rhythm in order that we are able to have correct sleep at night time, relatively than feeling drained all through the day,” she says.
And as you may count on, “lots of people report that in larger coaching volumes, they’re extra drained, and so they sleep higher,” says Laura Norris, a RRCA-certified working coach and licensed private coach. “You want extra sleep once you train extra.”
Why you could be having hassle sleeping post-workout
However there’s a flip facet to the connection between sleep and train, and in case you discover that your exercises are negatively impacting your capability to fall and keep asleep, it may very well be for a couple of causes.
“Whenever you train, it releases these hormones and neurotransmitters that put you in a stimulated state and prompts your sympathetic nervous system, which is your flight-or-flight system,” Gam says. “However to fall asleep, you want the other—you want the parasympathetic nervous system to be ramping up. And for most individuals, that’s what occurs.”
However in some instances, that flight-or-flight response may very well be sticking round for too lengthy—and messing up your sleep. One purpose why: “Somebody might have lots of life stress that’s piling on high of that train stress response and never letting the restoration response take over,” Gam says.
That stress response may additionally keep for too lengthy if somebody is a newbie whose nervous system isn’t but tailored to train, Gam says, or if somebody has dramatically ramped up their coaching unexpectedly. Or, it may very well be that you just’re simply doing intense exercise too close to bedtime. “It does take a while in your physique to shift out of stress mode and into that relaxation mode,” she says. Intense train additionally will increase your core physique temperature and coronary heart price, Dr. Nguyen says, which might take some time to drop and might intervene with sleep if it occurs too near bedtime.
If hassle sleeping post-exercise is a persistent downside, it may very well be that you just’re overtraining, and/or presumably underfueling, Norris says. “If an athlete is noticing that they chronically discover train disrupts their sleep, they need to have a look at in the event that they’re doing an excessive amount of depth or an excessive amount of coaching load, and so they need to have a look at in the event that they’re underfueling, whether or not round exercises or all through the day,” she says. “Not sufficient carbohydrates will depart your physique in additional of a stress response, and that may elevate cortisol ranges.”
If it’s a one-off time the place you’ll be able to’t sleep, or it’s after an enormous race, it’s not a priority, Norris says. However when it’s a sample, you need to look at your coaching and dietary habits.
To offer your physique sufficient time to ramp down after large exercises, goal to complete them no less than three hours earlier than bedtime.
Easy methods to fall—and keep—asleep after a tough exercise
1. Save intense train for earlier within the day
To offer your physique sufficient time to ramp down after large exercises, goal to complete them no less than three hours earlier than bedtime, Dr. Nguyen suggests. That ought to permit your cortisol ranges, physique temperature and coronary heart price to return to regular. (Simpler exercise classes gained’t have the identical sort of hormonal response, and may be carried out nearer to bedtime, Norris says.)
One more reason to get your powerful classes carried out lengthy earlier than it’s time to hit the hay? “Whenever you’re doing intense train, it’s possible you’ll be ingesting extra water, so that you’re working to the restroom extra usually,” Dr. Nguyen says. “That’s one of many greatest causes folks get up in the course of the night time.”
2. Use caffeine properly
“Some athletes use lots of caffeine round train classes,” Norris says. “Possibly they understand it or perhaps they don’t, but it surely’s in lots of sports activities diet merchandise.” Learn the labels in your gels, pre-workouts, and drink mixes so you realize precisely how a lot caffeine you’re consuming, and skip it totally for late-in-the-day exercises.
3. Prioritize your cooldown
“The post-workout cooldown is what basically places the brakes on the sympathetic nervous system and the stress response and begins to ramp up that parasympathetic nervous system and restoration response,” Gam says. She recommends spending 5 minutes post-workout doing deep stomach respiratory, ensuring your exhale is longer than your inhale. “That may gradual your coronary heart price and inform your parasympathetic nervous system to begin working.”
4. Concentrate on fueling
Prioritize fueling round your exercises and all through the day to keep away from the high-cortisol response that may include being underfueled. A certain signal you may use some extra energy in your food plan? If you happen to’re waking up in the course of the night time since you’re hungry, Norris says. If that’s the case, she recommends a pre-bed snack.
5. Maintain observe of your habits
Gam suggests preserving a log of your sleep and train so you’ll be able to concentrate on any patterns that emerge. “Log which exercises you’re doing, the way you slept that night time, and the way you’re feeling,” she says. “Have a look and see: ‘Am I doing lots of intense exercises and having some points sleeping? Possibly I must drop my depth down.’ Do this for a few weeks, see the way you reply, and make changes from there.”
6. Be cautious of overtraining
If hassle sleeping is coinciding with different signs like excessive muscle soreness or stiffness, lack of urge for food, fatigue or irritability, it’s potential that you’ve overtraining syndrome, which is a diagnosable medical situation and sometimes deserves a full break (of a number of days to a number of weeks, relying on the severity) from train, Gam says.
“If it’s not fairly to that time, however anyone is simply discovering that they’re having a tough time sleeping, I’d nonetheless have a look at their depth and their quantity and take just a little step again,” Gam says. “In the event that they’re used to doing lots of high-intensity coaching, sprinkle in some extra moderate-intensity coaching or reduce their complete exercise time just a little bit to offer their physique extra of an opportunity to recuperate.”
