Here’s how good sleep strengthens the immune system:
Production of cytokines: During sleep, the body produces proteins called cytokines, which help regulate the immune response. Certain cytokines are essential for fighting infections and inflammation. Lack of sleep can reduce cytokine production, weakening the immune response.
Cell repair and regeneration: Sleep is a time when the body repairs and regenerates cells, including immune cells. This helps maintain a strong and effective immune system.
Strengthening immune memory: During sleep, the immune system strengthens its “memory” of previous pathogens, which improves the body’s response to future infections.
Hormonal regulation: Sleep influences the production of hormones like cortisol, which affect immune function. Poor-quality sleep can disrupt hormone balance, weakening the immune response.
In summary, quality sleep helps the body better prepare for and respond to infections, while also promoting optimal recovery.
