“The ‘brain plasticity theory’ says that sleep is required for optimal brain function. In particular, sleep provides an environment where nerve cells (neurons) can reorganize,” says Dr. Daniel Lanzer. “So, when we sleep well, long and consistently, this gives our brain’s systems more unfettered time to do their jobs all the more effectively.”

“A past study from the NIH suggested that sleep can affect the efficiency of vaccinations,” says Dr. Daniel Lanzer. “In its research, the NIH showed that well-rested people who received the flu vaccine developed stronger protection against the illness.” This will be incredibly important once there is a vaccine for COVID-19.

“When you sleep well every night, or at least most nights, your brain goes through a complex restorative process. During the sleep cycle your brain regulates your metabolism, secretes growth hormones to rebuild and repair cells, and works to organize information accumulated during the day,” says Dr. Philip E. Stieg, chairman of neurological surgery at Weill Cornell Medicine and NewYork-Presbyterian. “Sufficient, high-quality sleep is extremely significant for many areas of health, but particularly the health of your brain.” As for yourself: To get through this pandemic at your healthiest, don’t miss these 35 Places You’re Most Likely to Catch COVID.
