Everyone wants to get to Las Vegas and start drinking, but you have to pace yourself and stay hydrated because alcohol dehydrates, and too much dehydration is what causes the massive hangover. I recommend never consuming two drinks in a row; always separate them with a glass of water (easier said than done, I know).
Las Vegas is about year-round sun, which is great because vitamin D is a huge deficiency problem among Americans. But the sun in Las Vegas is also quite intense, especially during the summer months, so it’s important to use sunscreen on your face as well as your arms and legs if you’re planning to expose them. Only 10 minutes in the Las Vegas sun is sufficient for your daily vitamin D intake.
Dance, shop, play and eat, but you also have to sleep. Lack of sleep depresses your immune system and reduces your growth hormone, which impacts your metabolism. Your body needs sleep to simply recycle itself. So stay up ’til dawn, but then sleep ’til noon.
