4 Ways To Boost Your Immune System

Your immune system must always be strong to fight off infections and illnesses, but not so strong that it causes more harm than good. These science-backed tips will help you improve your immune system and keep you healthy during these cold months.

1. Drink A Lot Of Water

Dr. Lin says, "Water is important because our blood and lymph, which have immune cells in them, need water in order to flow to circulate throughout our bodies." Health experts recommend drinking at least 2 liters of water a day.

2. Reduce Stress

Stress affects your mental and physical health. It can also weaken your immune system over time if you don't get enough sleep, eat unhealthy foods, and don't drink enough water.

3. Eat Well

Ensure you consume plenty of vegetables, fruits, whole grains, lean protein, and milk products, as they provide vital nutrients and support your immune system.

4. Reduce Your Alcohol Intake

Alcohol can weaken your immune system.
