I just presented an interactive seminar on stress relief for life and work for a professional business organization so it's front and center for me.
Before thinking about stress relief, ask yourself what stresses you out. Maybe your response to stress needs an adjustment.
When I'm stressed, I go to a relaxing place in my mind. With my background in hypnosis, I've put together a CD with guided meditations. The CD called "Restore" will be out real soon and can help you de-stress and balance.
Try crunching and munching on some almonds, dark chocolate, oatmeal and tuna fish. The vitamins in them can help you relax and create a better mood. Who ever said, chocolate was forbidden? In moderation, it's loaded with antioxidants that can help you fight off the negative effects of stress.
