#2 Insufficient sleep drops your testosterone and growth hormone!
Both men and women produce testosterone (T) for muscle mass, bone density, and fertility (men just produce more T than women)! With good sleep, your testosterone levels start off high in the morning and slowly drop throughout the day to a low point in the evenings.
But when we fall asleep, as long as we’re not disturbed, our testosterone can cycle back up again. Without ANY sleep, we actually miss the testosterone boost entirely. And when we chronically fail to prioritize our sleep and get less than we need, our testosterone levels remain sub-optimal, sometimes on the scale of 15-20% lower if we’ve accumulated a sleep debt.
We also produce growth hormone while asleep, a hormone that is essential for tissue repair, muscle growth, and overall vitality. Similar to testosterone, our growth hormone also peaks at night during deep sleep and is blunted with poor sleep, which impacts our ability to recover from daily wear and tear.
