Hello. I am a chiropractor so I understand how important it is to get back to basics and especially "natural" basics. I teach basic concepts.
1) Good nutrition(as best you can).
2)Get at least 7-8 hours sleep per night,if possible.
3)exercise 3-4 days per week at least 30-45 minutes each(aerobic is better than lifting weights) if your time is limited.
4)If possible,keep your spine aliened so you can reduce pinched nerves and increase communication between your body and brain and allow better functioning.
It sounds simple but as we all know it is not with our busy lives, so I suggest not to stress over it and do the best we can each day and try to improve with time. My patients appreciate this approach over making them feel guilty for not being "perfect" like some doctors do. I hope this response helps someone. Have a good day.
