The Role of Sleep in Immune Function

Adequate sleep is essential for a strong immune system. Find out how sleep deprivation affects your body's ability to fight off infections and illnesses.

Sleep: Your Body's Natural Defense

We often underestimate the power of a good night's sleep. Beyond just feeling rested, sleep plays a critical role in maintaining a robust immune system.

How Sleep Affects Immunity

During sleep, your immune system releases proteins called cytokines, some of which help promote sleep. Certain cytokines need to increase when you have an infection or inflammation.

The Risks of Sleep Deprivation

Lack of sleep can decrease production of these protective cytokines. In addition, infection-fighting antibodies and cells are reduced during periods when you don't get enough sleep.

Tips for Better Sleep

• Stick to a consistent sleep schedule.
• Create a restful environment, free of screens and bright lights.
• Avoid caffeine and heavy meals close to bedtime.

Prioritize your sleep to keep your immune system functioning at its best.
