Sleep is critical to good health. When we are not sleeping properly many things go out of whack: our cortisol levels decline, our sex drive declines, we age more quickly, our bodies don't produce the HGH that is needs...so many more. Lack of sleep messes us up!
The trouble is when people can't sleep, we tend to look at the immediate problem: take something to sleep. But it is more than that. It is our food, our exercise our state of mind, our stress level, our environment..so many factors.
You are already active 30 mins a day, that is great, what about your diet throughout the day?
Everyone is different and reacts differently to different foods but here are some common hindrances to sleep: high fat foods (at anytime throughout the day), caffeine (unless it is a natural green tea and used mid day), some medications contain caffeine and you may not even know it! -- alcohol, even that "one glass of wine" may not be right for you.
I have been using a nutritional system for 8 years. I only sleep about 6 hours a night AND I feel totally rested and ready for my day. I have the energy of a 16 year (with far better judgement) and I experience about 360 well days every year. Food, the right food, all day long is the key to overall health...including sleep.
Another thing to look at is your state of mind/stress levels. Are you waking up because you don't feel there is enough time in the day to get everything done? Maybe you are stressing about completing stuff or the kids. It may not be noticeable on the surface, but if you gave it some thought, you may be surprised at what you find.
What about prayer or meditation before bed or when you wake up? You tube has some great guided meditations for deep sleep or for a 30 minute refresher - do some research and find something that works for you.
And who knows...it could be the Spring forward thing...in reverse! ;)
