I’ve noticed lately that when I ask friends how they’re doing, half the time their response is either “tired,” “exhausted,” or “beat” — it’s almost as though being worn out is just another part of our busy, modern-day lives that we’re somehow supposed to get used to. But I believe that when our bodies and minds are in sync and healthy, we should feel amazing and energized even when our schedules are full. If we’re getting enough rest, exercising and eating foods that fuel us, we should feel strong, satisfied and alert. But as most of us know, that’s easier said than done, and there are several reasons why you may be feeling mysteriously tired.
