Prevent From Colds and Flu

Protect Yourself to Prevent Colds and Flu

During the late fall and throughout winter, most people are cooped up inside, often times sharing space with others who may be sneezing and sniffling. You may not be able to completely prevent colds and flu this time of year, but by practicing good hygiene and being careful to avoid cold germs, you may escape cold and flu season unscathed.

#1. Drink Plenty of Fluids

General good health practices keep your body strong and ready to fend off cold germs and the flu virus. And that includes drinking plenty of water. In fact, one recent study found that staying hydrated may boost a particular immune response to enable your body to better fight the viruses. Stay hydrated by drinking a lot of fluids, especially water, and by avoiding caffeinated drinks. Shoot for six to eight glasses of water per day, more if the weather is hot, says Elder.

#2. Exercise to Strengthen Your Immunity

Exercise not only makes you feel great and helps you stay fit, but it also boosts your immune system and can help prevent cold and flu viruses from making you sick. Additionally, warding off extra weight is important for overall health, particularly when it comes to preventing colds and flu. A recent study found that overweight and obese people were more likely to fall ill or be injured, and researchers determined that higher BMI indicated an increased risk of injury and illness.

#3. Take Probiotics

Probiotics are "good" bacteria that can help keep the body healthy and protect it from "bad" bacteria — and there's even some thought that taking probiotics may help to prevent cold and flu viruses. In fact, a recent study found that regular use of probiotics kept people healthier and reduced the incidence of upper respiratory infections (like the common cold). Consider eating foods that contain probiotics or taking probiotic supplements to prevent flu.

#4. Eat Healthy Foods

A healthy diet can strengthen your immune system — and help you prevent flu and cold viruses from attacking. "Fruits, vegetables, low-fat proteins, and complex carbohydrates are the keys to good nutrition that will stoke your immune system," says Elder. A recent study found that providing seniors with plenty of nutrients powered their immune systems and helped them to prevent the flu virus.
