Registered Dietitian, Ashley Koff, shares three simple things that can keep you healthy and happy during the holiday season (as well as all year round).You can't live in a bubble in order to stay healthy... you wouldn't even want to, because part of optimal overall health is being mentally and socially stimulated.

Registered Dietitian, Ashley Koff, believes there are actually three simple things that can keep you healthy and happy during the holiday season (and all year round).

She joins Naturally Savvy host, Lisa Davis, to share these top three tips.

Sleep

No pill, no food, no exercise can replace what sleep can do for you from a health perspective.

Try to stick with a reasonable bedtime, and aim for five out of seven nights of good sleep. More than two nights out of your routine will throw you off. Remember, it's about quality, not just the amount of hours you get. You might get into bed, but your brain could still be buzzing.

Finally, do things during the day that will engage your energy or energize you more.

Hydration

This is probably the easiest tip to incorporate, but the one that's forgotten about as the weather gets colder. Instead of an iced tea for your caffeine break, you may be doing a latte. People also tend to turn towards soups or other high-sodium foods this time of year, which causes you to retain water. Your body cannot do its proper detoxification and elimination when you're dehydrated, nor can it effectively use the nutrients you're ingesting.

Focus on your water consumption and get plenty of vegetables.

Incorporate Elderberry

Elderberry engages the whole spectrum of your body's immune system and can actually work very quickly to cut off the "triggers" of illness. The best way to get elderberry is either in liquid or capsule form; both will get you highly-concentrated results (just make sure you are buying organic versions).
