Exercise causing increased metabolism in your body. It released more energy, producing heat and sweating ,your muscles are more active (contracted) and blood supply to organs increased. For sleeping your body needs to be in a relaxed state, relaxation of muscles, low brain funtion level., low metabolic rate....

I don't know why I have trouble sleeping after exercise. Maybe because my body is tired but my brain is still too active which gives me trouble with trying to fall asleep.

Exercise before sleep can cause stress on the body and mind. The stress winds up the body preparing it for action and can cause you to suffer insomnia.

Your body is probably heated up and physically awake after exercise. I have this problem too sometimes. If you don't already, I would recommend doing some stretching or yoga after a workout to help "cool down" from the exercise.

When you exercise, your heart rate increases and the body prepares itself for extended physical activity, so when you immediately lie down afterwards, it can take a while for the body to make adjustments.

Here is my take on this question... You want the room to be dark. You're pineal gland releases a hormone called melatonin as a response to darkness, and it's function is to help you get to sleep. It has antioxidant properties, along with many other functions, but you will be taking it to sleep. There is a fall off in melatonin release by the pituitary with aging, Supplementing this dietary supplement might counteract this? Consult with you're physician first though. This is one of the reasons people have more difficulty sleeping as they get older. So, try the melatonin if you're having trouble. The other thing you can do is to have a cup of herbal tea right before bedtime. And sweeten the tea with either sugar or honey. That's right. Real sugar. A teaspoon of sugar is about 5 grams of carb, which won't do a lot to hinder your weight loss, but it will be enough to shut down ketone production long enough to get you to sleep. And if you think a teaspoon of sugar isn't all that much, remember, it's the total amount circulating in your blood if you have a normal blood sugar.

Because during exercises you inhale and exhale rapidly so you get hyper-oxygenated and so you get energetic. It's like drinking redbull in the middle of the night (do you expect any sleep afterwards?)

After exercise, you'll have high blood pressure, which difficult to relax or sleep. If you force your body to sleep, maybe, at midnight, you could suffer from high headache, caused by the pressure (i felt them). So, relax after exercise and take time before go to bed.

Exercise wakes up your body, try to relax 2 hours before going to bed in order for your body to feel rested

That is because your body is in a "hyped up" stage. It is in full mode and is anticipating more action. That is why after you exercise, drinking a glass of milk can help since it lowers stress levels and helps you relax making it easier to dose off. Another method is to take a warm bath before going to bed.

Exercise is an exhilarating activity, unlike sleeping. It's actually recommended that one exercise during study breaks to help keep themselves awake and attentive. If you find yourself having difficulty sleeping at night, and you exercise around that time as well, you may want to consider exercising earlier in the day instead.

Usually when the heart speeds up and begins racing, other internal organs kind of speed or slow to allow for exercise. Once exercise has stopped it may take a while for our body, and mind, to stop racing and allow us some good quality exhaustion.

Trouble sleeping after exercise is mainly caused by the increased levels of adrenaline after a workout. Because the hormones which is produced during workout has the potential to keep you awake at night, unless the hormones has the proper time to return to normal before you go to bed. Therefore, it is essential to exercise before bedtime to avoid any sleep troubles as the body needs to calm and relaxed to sleep well.
August 21st, 2015 5:15pm
Exercise causing adrenaline to run through your body. Adrenaline is a rush of energy. When you have a lot of energy, your body has a hard time relaxing quickly. When the body is not relaxed, it's difficult to fall asleep. Many suggest doing exercise in the morning or earlier in the day. Others say it's best not to do exercise a half hour before going to bed.

the heart usually beats really fast after any kind of exercise . the brain relieves endorphins. That keeps us awake , and the muscles also work after you have done exercise.
August 22nd, 2015 8:20pm
Because your body is still active and takes a while for it to get back to normal so you can fall asleep
August 22nd, 2015 9:20pm
When a person exercises a chemical in the body called endorphins is realsed, which triggers energy.
August 28th, 2015 12:07pm
Stimulation - endorphins. Although some forms of exercise may calm one down, such as gentle forms of yoga.
August 29th, 2015 12:40am
Exercise raises your endorphin level, and gets your circulation going. Its best to exercise in the morning because your body needs to rest and rejuvenate at night.
August 29th, 2015 3:15pm
Maybe because your pulse rate is increased and blood tends to pump faster so it's not easy to sleep at that point in time
August 30th, 2015 6:58pm
Be used your heart rate is high. just like when you drink caffeine, the heart rate does up and can't sleep at all
September 2nd, 2015 4:00am
It could be a number of reasons, but often times a hard workout will trigger the body to produce endorphins. An endorphin is a chemical compounds that ups your mood and is considered a stimulant. If you do a hard workout before bed, you may be producing endorphins that disrupt your ability to sleep.

Exercise can affect you physiologically and get your body wired up so it can often be difficult to wind down and sleep soon after. The gets used to working hard, pumping more blood, and increases in heart rate so often exercising in the morning or after work can get you feeling energetic enough to deal with the demands of the day!

There is good causes for it: endorfine and adrenaline. Once you exercise , your body produces them both and you will be awake and actually feeling very well !! So, if you exercise ( and that is good!!)avoid doing so at night, if possible.
September 3rd, 2015 3:55pm
maybe because you're out of breath, and exhausted because of the sweat. Take a cold bath and relax yourself before sleeping.
September 4th, 2015 8:32pm
This is called post-workout insomnia. You might be reacting to the increased adrenaline in your body. My best advice is to avoid intensely working out less than 3 hours before when you plan to go to sleep. Hope this helps x
September 5th, 2015 2:19pm
Because by doing exercise, you get your adrenaline going and wake everything up! However exercise can actually help you sleep if you do it earlier on, before you are going to sleep
September 6th, 2015 4:44am
Exercise can work as a stimulant in the body, raising heart rate, breath rate, and other measures generally associated with being alert and active. This cause sleep to be more difficult.
September 6th, 2015 3:12pm
If it's right after, your endorphins and energy is still running high. Your blood is pumping from the exercise, you feel energized and ready to go. Exercise makes you awake, even if your body feels physically tired. My suggestion is to work out at least an hour but ideally two before the time you need to go to bed.
September 8th, 2015 3:25am
I don't know the reason why, but I do know that it is advisable not to exercise too close to bedtime. I think that is referring to vigorous exercise, however, because I know for those who have restless legs, stretching sometimes helps.
