Why is it called “beauty sleep” even though you wake up looking like a hot mess?
<|assistant|>
It's called "beauty sleep" because when you sleep, your body produces human growth hormone which helps repair muscle cells, build lean mass, improve skin quality, and gives your skin a chance to replenish and rejuvenate itself overnight which gives you that radiant look the next day. However, when you wake up you may look like a hot mess due to make-up, dirt, and other environmental factors that were not washed or addressed during your sleep.
