Things that weaken immunity
According to several studies, high sugar intake can suppress the immune system by around 45% for almost 5 hours.
A child that regularly consumes sugar will have a lower chance of successfully fighting off potential infections, so they are more likely to get sick.
Stress has an evident negative impact on the quality of life of anyone who has it, including children. It can also significantly weaken the immune system.
When we are stressed, we produce more cortisol. This is why it is called the stress hormone. Cortisol puts the body on edge and prepares it for fight or flight.
Low vitamin d
If levels are low, your immune system suffers greatly, and you are more likely to get sick and take longer to get back on your feet.
