From dry chapped skin to seasonal sniffles to holiday overindulgence, this time of year presents a unique set of health challenges. Here are 30 easy ways to stay looking and feeling your best during the cold-weather months.

1. Naturalize Your Hand Sanitizer: Most hand sanitizers are made with medicinal-grade ethyl alcohol, which can be a skin irritant. It may also hamper natural oil production, leaving skin dry and flaky. Use products with naturally sourced alcohol and anti-microbial essential oils.

2. Supercharge Your Immunity: Studies show that NAC (N-acetylcysteine), vitamin C, zinc, and selenium work well.

3. Halt Party Pig-Outs: To curb your appetite, have a cup of miso soup, bone broth, or an apple before heading to holiday events.

4. Eat Oysters: They’re the richest source of immune-boosting zinc.
