6 Everyday Choices That Quietly Weaken Your Body’s Immunity (3 of 4)

Neglecting To Exercise On a Regular Basis

Consistent exercise is one of the best habits you can take advantage of to support your health. Exercise helps to support circulation, which encourages white blood cells to travel efficiently throughout the body, which also reduces inflammation. However, many people don’t move enough, or they move too much.

A lifestyle that is more sedentary can make your immune system more sluggish. In contrast, high-intensity exercise without enough recovery time can actually suppress the immune system. The key to exercise for the best immune system response is balance. Regular exercise that is moderate—like brisk walking, cycling, or strength training a few times each week are great options that provide immune support without overworking the body.

Overindulging in Nicotine or Alcohol

Social habits like smoking and drinking might seem harmless if done in moderation, but there is a cumulative cost to the immune system. Alcohol can disrupt the gut barrier, which allows dangerous pathogens to circulate the body. It can also disrupt sleep patterns and quality, and can deplete vitamins in the body that are essential for immune repair.

Meanwhile, nicotine can reduce oxygen flow and constrict blood flow, ultimately impairing the immune cell’s ability to reach infection sites. Cutting back on both drinking and smoking, or quitting altogether, will give your body a chance to rebuild necessary defenses in just a matter of weeks.
