Sleep, sleep, and more sleep. Sleep is so good for our bodies, and too often we let it fall by the wayside. When we sleep, our bodies have a chance to restore, rebuild, and reconnect. It’s also an opportunity for your mind to relax. Sleep, your circadian rhythms, and your immune system are all interconnected, and when you don’t get enough sleep, your immune system is suppressed, and you’re more susceptible to catching something to make you sick. Adults on average need seven to nine hours of sleep per night.
