SLEEP TO BOOST YOUR IMMUNE SYSTEM

Sleep can help you protect yourself against COVID-19 and other viruses

It was World Sleep Day on 13 March, so it seems like a good time to look at how sleep can help protect against illness. Sleep helps build and promote a strong immune system.  Lack of sleep compromises your immune system.

Lack of sleep can make you sick

Research has shown that people who don’t get quality sleep or enough sleep are more likely to get sick after being exposed to a virus. Lack of sleep can also affect how fast you recover if you do get sick. 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, or when you’re under stress. Sleep deprivation may decrease production of these protective cytokines. In addition, infection-fighting antibodies and cells are reduced during periods when you don’t get enough sleep. Cytokines are both produced and released during sleep, therefore making sleep even more important.  Chronic sleep loss can also reduce the effectiveness of flu vaccines by reducing your body’s ability to respond. According to the Sleep Foundation (US) to stay healthy, especially during the influenza season, you need to get the recommended seven to eight hours of sleep a night. This will help keep your immune system strong, whilst also protecting you from other health issues including heart disease, diabetes, and obesity. 

Of course, just getting enough sleep is not the only way of building a strong immune system and guarding against illness. One should also:

  • Wash your hands with soap regularly
  • Avoid close contact with people who are ill
  • Take vitamin C and/or multivitamin supplement
  • Eat well
  • Get a flu injection

Are you sleeping enough?

Blue light from electronic devices, televisions and LED lights reduces the body’s ability to manufacture the sleep hormone melatonin, which is needed for good quality sleep.  SleepSpec are amber tinted glasses that absorb blue light in our environment and allow the body to produce melatonin.

Melatonin helps boost immune system

Aside from assisting the body to sleep, melatonin is also an essential hormone for immune support and disease prevention. As we age, our T-cells, which regulate our immune response and fight disease, become less effective; this in turn breaks down our immune systems. Melatonin increases T-cell activity, which creates a more powerful antibody response and helps us fight viruses. It also supports the thyroid, which bolsters our immune system.
