Getting enough quality sleep is crucial for maintaining a strong and healthy immune system. During sleep, the body produces and releases cytokines, a type of protein that targets infection and inflammation, helping the immune system to fight off viruses and bacteria. Lack of sleep can weaken the immune response, making the body more susceptible to illnesses.

In addition to cytokine production, sleep also plays a role in regulating the production of antibodies and immune cells. Studies have shown that individuals who consistently get an adequate amount of sleep are less likely to get sick when exposed to viruses. It is recommended that adults aim for 7-9 hours of quality sleep each night to support proper immune function.

Key Lesson Concepts:

• Sleep is important for immune system function
• Cytokines are produced during sleep to fight infection
• Adequate sleep can reduce the risk of getting sick
• Adults should aim for 7-9 hours of sleep each night
