For many, the long holiday weekend means it's time for a family trip. When you are checking your to-do list before you jet off, make sure to check your health twice. From shopping to meeting with friends and traveling for break - it is important to stay healthy to make the most out of the break.

John Revis, MD, Internal Medicine at NorthShore, offers tips for keeping healthy while on the go:

• Plan ahead. Take the time to sit and plan out everything you have to do. Writing everything out will help decrease your anxiety – be sure to create a to-do list or put it in a calendar. When you are filling in your calendar, do not overbook yourself and be sure to include breaks.
• Prepare your snacks. When you are out shopping or traveling, plan your snacks in advance. Be sure to stop at the store and grab nutrient-dense foods. Think of foods with the most minerals and least amount of calories; such as a handful of nuts, string cheese, mixed seeds and low-fat yogurt. Having nutrient-dense food on hand will help while you are out and about.
• Blend your breakfast. If you have to leave early or quickly in the mornings, try making a smoothie. Add in some leafy greens for your nutrients, Greek yogurt for protein and anything else you would like to make it tasty for you.
• Fuel up. Running through malls or traveling on airplanes can dehydrate you. Bring a reusable water bottle, these allow you to fill up at water fountains for free. Be sure to drink enough water so your pee is a light yellow – which means you are properly hydrated.
• Wash the germs away. Before you sit on a plane, train or at a restaurant table, be sure to wipe down the tabletops, arm rests and any other surfaces to kill the germs from the previous occupant. Wash your hands or use hand sanitizer before you eat – your hands are your biggest germ enemies. They have touched elevator buttons, ATMs, doorknobs and many other public germ-breeding grounds.
• Steer clear of treats. It is so easy to convince yourself that because you have been on your feet all day from shopping or traveling that you can reward yourself with a sweet treat. Indulging here and there when you burn minimal calories adds up! Instead, reach for one of your snacks that you have already prepared.
• Rest up. During the busy season, be sure to give your body at least 8 hours of sleep every night. If you do not consistently get a good night of sleep, you increase your chances for catching a cold because you have worn down your immune system.
