How? When you train, stress hormones are released such as adrenaline and cortisol. Usually these would then lower back down after a workout, but if your body is constantly being put under the stress of exercise, the stress hormones stay active, in turn, making it difficult to get the best quality sleep possible. Then this can lead to even more exhaustion. Taking rest allows your hormones to stay balanced for a restful night’s sleep.
