Why Sleep Matters for Covid – Your Immune System
Your immune system and sleep are connected. Sleep loss impacts your immune response and, in turn, your immune system alters your sleep. If you are trying to help fight against Covid-19, getting consistent quality sleep will be one of your primary methods of helping fight this disease and ensuring optimal recovery.
Molecules called cytokines are signaling molecules in the immune system and the brain. Sleep deprivation decreases your body’s production of cytokines and inhibit your immune response to deadly illness like Covid-19, as well as other diseases like:
- Flu
- Cold
- Chronic inflammation
Specifically, lack of sleep prevents your immune system from building up its forces, meaning that your immune system will be overloaded by illness and will likely take longer to recover.
During illness, increased levels of pro-inflammatory cytokines correspond with increased fatigue, which is why you feel tired when you are sick. It’s your body’s way of telling you to sleep more and recover quicker from your illness.
The key point here – along with a disclaimer – is that sleep may help you boost your immune system and protect you from, or mitigate, Covid-19 impacts on your health. However, Covid-19 is not well understood and underlying conditions and other factors may also render good-sleep a non-factor. That being said, getting plenty of sleep this winter and/or if you have signs of Covid probably won’t hurt!
