Expert Opinion: How Sleep Affects Your Immunity

Sleep is essential for overall health, including immune function. When you don't get enough sleep, your body produces more stress hormones, such as cortisol, which can suppress immune function. Lack of sleep can also disrupt the production of cytokines, proteins that help regulate the immune system. Additionally, sleep helps to clear away waste products from the brain, including beta-amyloid plaques, which are associated with Alzheimer's disease. Sleep also helps to regulate the production of melatonin, a hormone that has antioxidant and anti-inflammatory effects. Melatonin can help to protect the cells in your immune system from damage, and it can also improve the function of immune cells. In summary, sleep is essential for a healthy immune system. When you don't get enough sleep, you are more likely to get sick and your body may take longer to recover from illness. Aim for 7-8 hours of sleep each night to support optimal immune function. Here are some additional tips for getting a good night's sleep: * Establish a regular sleep schedule and stick to it as much as possible, even on weekends. * Create a relaxing bedtime routine to help you wind down before bed. * Make sure your bedroom is dark, quiet, and cool. * Avoid caffeine and alcohol before bed. * Get regular exercise, but not too close to bedtime. * If you have trouble sleeping, talk to your doctor. There are many treatments available to help improve sleep. By following these tips, you can improve your sleep and boost your immune system.
