It’s the time when the body and brain detox, recover, rebuild and restore. We can go many months without food, a few weeks without water, but only a few days without sleep. Even a single night of poor sleep can take several nights worth of good sleep to overcome.
Sleep restores the body and improves energy levels, which has a positive impact on your mood, mental acuity, cognitive performance, and overall well being.
Lack of sleep has been linked to cognitive decline and an increased risk of conditions such as Alzheimer’s and dementia.
When you sleep your heart rate slows down, heart rate variability increases, and blood pressure decreases, therefore the heart and vascular system are able to rest and recover. Alternatively lack of sleep can be linked to an increased risk of heart conditions such as heart attack, heart disease, and heart failure.
Poor sleep can wreak havoc on your hormone production, especially growth hormone and testosterone. Want to dominate in the gym? Then dominate your sleep!
