Yes, regular workouts promote good sleep. Your body needs some activity to feel good and sleep at the end of the day.
But does that mean that you can embrace intense workouts and overtrain to the point that you break down? No. In fact, your sleep quality goes for a toss if you do that.
Intense exercise can be stressful and it has some side effects if you don't listen to your body's limits and warnings. Read on to know more...
Intense weight training could be strenuous on your system. When your mind and body fail to take that load, your sleep patterns may take a hit. Mood swings may occur. Your overall performance may also dip.
When researchers observed the sleep patterns of two groups of people engaging in various types of workouts, they realised that performance, moods and sleep patterns get affected if the body is stretched beyond its limits in the workouts.
The effect is too obvious especially after a week of intense workouts. Anger, tension, depression, fatigue, mood swings and insomnia are considered as the side effects of over training.
What are the reasons? Blame adrenaline and cortisol. When the body is strained, it feels stressed up and that releases cortisol and adrenaline. They are the hormones which may affect the sleep.
Also, exercises release norepinephrine. This hormone speeds up your heart rate, boosts circulation to your muscles and helps your mind stay alert. When the levels of such hormones rise towards the evening, you may find it tough to fall asleep.
Cortisol, on the other hand, may try to help you by keeping your muscles active. The body tries to postpone sleep when the whole system is filled with hormones which are trying hard to stay active and alert.
What's the moral of this story? Well, over-training could kill your sleep. In the long run, recovering from the soreness becomes a challenge when your sleep quality dips. Moderation is advisable. Talk to your gym instructor about that.
