10 Tips to Keep You & Your Family Healthy This Winter

The medical field has long known that people are more prone to catching colds and flus during the cold winter months. Previously, scientists primarily attributed this to people living and breathing together in enclosed environments. But cold temperatures also make our immune system sluggish and prevent our bodies from fighting off infection, according to a 2015 PBS report, "Scientists Finally Prove Why Cold Weather Makes You Sick." Now, amid the COVID-19 pandemic, taking extra precautions during the winter to maintain health is incredibly vital.

1. Keep Your Home Warm

Maintaining warmth is essential to ward off winter-related illnesses. Keep your home comfortably warm by setting your thermostat between 68° and 75 F. Optimum daytime temperatures for living areas are 70° to 72°F. At night, set the thermostat just a couple of degrees cooler for your bedrooms. What's comfortable varies from person to person, so if you feel cold at 72°, turn it up a notch or two.

2. Dress in Layers

Layer your clothing, whether at home or outside. Wear a t-shirt or cami, long sleeve shirt or blouse and a sweater over the top. This way, you can set your thermostat at a moderate temperature and peel off layers to maintain the perfect comfort level. Layers will also ensure you maintain comfort when you go out. We lose most of our body heat through the extremities, so it's vital to keep hands, head and feet warm.

3. Eat Healthily

A healthy diet is essential year-round, but during the cold winter months, certain foods are particularly beneficial to the immune system. The much-criticized starchy potato is high in vitamins B6 and C, both of which boost immunity.

Collards, kale and chard, among other dark leafy greens, are high in vitamins A, C and K, and winter squash, including pumpkin, butternut, spaghetti and acorn, is high in beta-carotene. Our bodies convert beta-carotene to vitamin A, another vital source that boosts the immune system.

Several fruits are also particularly beneficial and protect against winter-related ailments. Citrus fruits are a rich source of vitamin C. Kiwi packs even more of a C punch than oranges. Other fruits that help keep your immune system strong include pomegranates, blueberries, cherries and even bananas.

4. Drink Plenty of Water

Dehydration causes a host of health complications. Despite this, most people don't drink nearly enough water. As a result, health experts say they're in a state of chronic dehydration. According to the report, "Prevalence of Inadequate Hydration Among U.S. Children and Disparities by Gender and Race/Ethnicity: National Health and Nutrition Examination Survey," half of all children are dehydrated.

How much water should you drink each day? A commonly repeated recommendation is eight 8-ounce glasses per day. But why would a 100-pound inactive woman need the same intake as an active 220-pound man?

It turns out there's a formula to determine how much water you should consume. Divide your weight by 2.2. Next, if you're under 30, multiply by 40; between ages 30 to 55, multiply by 35; if older than 55, multiply by 30. Now divide your result by 28.3 for the number of ounces you should drink daily. Divide this by 8 to determine the number of cups.

5. Wash Your Hands

One of the best ways to reduce the spread of germs is by washing your hands regularly. This not only reduces the risk of transferring your bacteria to others, it reduces the chance that you'll transfer bacteria to yourself.

When someone with a cold, flu or coronavirus touches a doorknob, handrail, gas pump or other objects, their germs get transferred to the object. Bacteria can survive this way for days. If you come along and touch the germ-ridden object, the bacteria transfer to your hands. Then, when you scratch your nose or grab a cookie to eat, you become infected.

When you wash your hands, use soap and warm water. Rub between your fingers and underneath your fingernails. Then rinse your hands for 20 seconds and dry them thoroughly. In public restrooms, use a paper towel to turn off the water and open the restroom door after you've washed your hands.

6. Keep Active

An active lifestyle is crucial to a healthy heart, lungs and bones. But a moderately active lifestyle also improves your immune system, according to a 2010 study, "Exercise and Respiratory Tract Viral Infections." Prolonged intense exercise suppresses the immune system, however.

The key is to exercise regularly but in moderation. Unless you're trying out for the Olympics, a 20-mile run won't likely serve you well. Instead, opt for a brisk walk for 30 to 60 minutes daily. If you want to do something more vigorous, try 20- to 30-minute runs or aerobic workouts several times a week with weightlifting in between.

7. Avoid Public Places During Outbreaks

If we learned anything during 2020, it's important to avoid public places and to practice social distancing during a pandemic. When you hear of a flu or virus outbreak in your area, stay home if possible. This will serve double-duty by keeping you out of the cold that makes you more susceptible.

8. Take an Antiviral Medication

If you're exposed to the flu, be proactive and nip it in the bud with a prescription for Relenza or Tamiflu. The only catch is there's a short window of opportunity for these medications to be effective. These treatments must begin within 48 hours of the onset of symptoms, so as soon as you feel signs of the flu coming on, call your doctor. If your doctor can't see you right away, go to an urgent care.

9. Get a Massage

According to a 2010 study for Cedars-Sinai Medical Center, Swedish massage increases lymphocytes, improving the immune system's effectiveness. So now you have the perfect excuse to exchange massages with your partner to help stave off illness.

10. Get Your Zs

When we rest, our bodies release cytokines, which promote sleep and ward off infection. When we don't get enough sleep, we're deprived of the protective cytokines, leaving us more susceptible to infection.

Sleep requirements vary, but children should get at least 10 hours of sleep each night. Teens require nine to 10 and adults seven to eight.
