  • But supplementation with glutamine (a specific amino acid widely thought to improve immune function) hasn’t shown much benefit.
  • In those with low vitamin D status, the protection was even greater reducing the risk of respiratory infection by almost a half compared with placebo.

Prolonged bouts of strenuous exercise have been shown to result in transient depression of white blood cell (leukocyte) functions and it is suggested that such changes create an “open window” of decreased host protection, during which viruses and bacteria can gain a foothold, increasing the risk of developing an infection (Walsh et al. )

But, again, check with your health professional. But they can also cause respiratory illnesses such as the flu, bronchitis, and pneumonia. More recently, some interesting research from the University of Colorado demonstrated that in a population of couch potato office workers, introducing six bouts of five-minute brisk walking throughout the day was more effective than a 30-minute daily gym-like workout for overall health, including improving mood and decreasing fatigue. These antibodies or WBCs circulate more rapidly, so they could detect illnesses earlier than they might have before. Apart from exercise, a good night’s sleep is another way to keep your immune system humming.

  • Tipton (2020).
  • The brief rise in body temperature during and right after exercise may prevent bacteria from growing.
