May 30, The importance of habits for immune system health Our immune system is a complex network of tissues, cells and organs that protect our body from harmful pathogens and foreign substances. Habit 1: Eating a nutrient-rich diet A nutrient-rich diet is one of the most important habits for a robust immune system.

Habit 2: Staying hydrated Drinking enough water is essential for overall health, but it is significant for immune system health. Habit 3: Getting enough sleep Sleep is often overlooked in immune system health, but it is crucial.

You can also add vegetables to soups and stews, smoothies, and salads. Sleep is when we repair our cells, especially our brain cells, and when we do most of our digesting and absorbing of nutrients. Not getting enough sleep can lead to higher levels of stress hormones and it can cause more inflammation in the body.
