After exercising you tend to get a surge of energy :) This could be why. If it helps you could take Melotonin or look up various tips on how to relax and sleep after exercising.

Because your activity just peaked and has to easy down. The physiological changes made through the recent activity prevents, to a certain degree, rest until the body has eased off from its active state.

After you exercise, your body is in full energy release. That's you you have trouble falling asleep after exercising. You need to make sure that you give at least 2 hours time for your body to cool down before you can go back to sleep. If you really have to workout at night, try doing low intensity workouts. That helps a lot.

You have trouble sleeping after exercising because you may be too tense. Do not over work out, but don't under work out either.

This is because you have not exercised to the point of exhaustion, therefore your heart rate is likely to still be too high for you to rest comfortably

You may have trouble sleeping after exercising because your heart rate is probably high after exercising

Exercise gets your heard rate up, making you more awake. It helps to not work out an hour before you go to bed or to cool down after your workout to get your heart rate back down

After exercise your heart is racing and you're very awake. If you are going to exercise before sleeping try to do a calming exercise like yoga.

When you exercise, the exercise releases endorphins in your body. This rush of hormones which can often cause you to feel perky and awake and have additional energy!

Maybe you exercised too much or too "strongly" for your body, try to reduce exercise and see. If it keeps going like this see your doctor.

Normally if I can't sleep after exercising, it is normally because I am pumped up after my workout. I generally have spent time trying to increase my heart rate, and when I sleep, my heart rate goes down. While my brain focuses on trying to slow down my heart, it is hard to tell my brain to make me sleep.

what does exercise do? It not only wakes you up but almost all the important muscles in your body too in a manner of speaking wake up. That is why those who don't exercise become lethargic and fall into a lethargy induced slumber. After exercise all the doors and windows of your body shop are open. One by one you start closing the windows and doors before sweet slumber pulls down the shutter of your body shop

A lot of the time, it's difficult to allow your body to shut itself down after you vamp it up a bunch.

Even when you finish a workout, the body takes a long time to calm down. Endorphins and other chemicals have been released to make you more alert and energetic. Your body is also slow to fully cool down and calm down after exercise, and until this happens, you will be fighting an uphill battle when trying to relax and sleep. In fact, exercise can cause your core temperature to be increased for four or five hours after working out. Finish you exercise routine 3 to 4 hours before bed or do it during the day or morning.

I have a feeling to believe that is because your adrenaline is pumped up and it stops your body from being anything but active.
September 24th, 2015 3:18am
Excising before going to sleep makes your body get energized and it is difficult for your body to be tired after physical activity

From scientific research, after exercise your body becomes more "active" in essence, by exercising, your making yourself more awake, so when you come to get into bed, your body will disagree with you and wants to stay up longer

Exercise causes adrenaline production. It's generally recommended not to do any heavy exercise 1-2 hours before bed. If you're tired you're more likely to not exercise as well as you would have if you had the energy you had earlier in the day as well.

Sometimes, right after a workout, we have all these hormones like adrenaline going through our bodies like crazy, making us all pumped up for the day — that's one of the reasons many people choose to work out first thing in the morning, to jump start their day! If you work out several hours before going to sleep, this could be solved. If it still doesn't help much, maybe a workout earlier in the day could really be the jolt of energy your day needs! That's really good news — I wish I had that kind of energy-booster :) Good luck!

You may have trouble sleeping after exercise, because your body is super excited. You need some time to calm down and put the blood pressure, heart beat etc to a normal condition.
October 22nd, 2015 2:35am
Your body needs to calm down and your muscles need you relax before your brain can actually rest into a sleep.
October 22nd, 2015 11:48am
Because when you get pumped up from exercise, it makes you more awake and happy.
October 22nd, 2015 5:37pm
Exercising boosts your adrenaline and endorphins, which can keep you feeling "up" long after you've stopped. I know fitness experts recommend leaving at least two hours from when you stop exercising to the time you need to be in bed.

your blood is pumping and your heart rate and blood pressure go up, try doing some yoga or listening to relaxing music afterward

It's possible that you're having trouble sleeping after you exercise because your body isn't used to being so active. Your heart has to pump harder and more often than usual, and your body has to try and readjust to find some kind of balance with the activity. So it's likely that you might just need to do some calming exercises, like mindfulness or yoga nidra, to try to naturally calm your mind/body down. Your mind and your body are very often correlated, so if your brain starts to calm down, your body will naturally follow suit, or vice versa.

After exercise your body is pumping with energy and in turn it becomes harder to sleep, it's hard to calm yourself after exercising. Maybe try exercising in the morning or early after noon.

Exercise is great, but it also gets your heart rate up and your body ready for more activity. Therefore, sleeping right after exercise can be difficult.

Simply put, it's most likely because cortisol significantly increases after exercise (especially after heavy/intensive exercise). Cortisol is associated with anxiety and wakefulness. My tip is to not intensively exercise too close to sleep and/or to only do some light exercise before your desired bed time.

I have the same problem, my doctor said it was probably because your brain and body needs time to calm down, try waiting until the afternoon to exercise, then eat your dinner or shower, and then sleep. Those kinds of things can help your mind and body calm down.
