Ah, sleep. There’s nothing quite like a good night’s rest. Tucked in under the covers and catching some zzzz’s for eight hours… What? You’re not familiar? Let’s look at some ways to address that. Sleep is probably the most under-rated protective health measure out there. Without deep, restorative sleep, your body cannot complete the processes of healing and regeneration that are meant to take place during sleep. The number of hours of sleep necessary varies some but it is generally advised to get between six and eight hours of sleep per night.
