Take 10 minutes to just breathe
Drink less coffee (if you do need caffeine try drinking matcha, green tea or oolong instead).
Do some simple yoga poses in the morning or at night before bed, such as Yin, Hatha or for the more experienced Vinyasa.
Find a stone you like and carry it with you, some excellent grounding stones are either black or red like obsedian, jet or carnelian. Although i've heard obsedian can have limiting effect on a persons confidence, so i wouldn't over use it.
Try taking some supplements from the health food store, or pharmacy such as adaptagens which i've described as also useful for balancing the hormones as well. Some good remedies are Magnesium for calming the nerves, (best taken in the morning before a meal with potassium or alternatively a banana, see below ) Gingko, Tumeric, & St.Johns wort.
Find some meditation music, and zen out.
Use some essential oils in a diffuser, some good ones are Lavender, rose and anything citris like lemon, orange or bergamot. Chamomile and frankinsense are also really great for calming the nerves.
Detox and replenish your Body\Mind by eating more vitamins and mineral rich foods, also take some pro-biotics to help eliminate any unnecessary bacteria in the gut by eating yogurt or alternatively taking a supplement. Replacing your healthy flora into the digestive system.
Take a B vitamin or instead eat Beetroots, Brocolli or even better broccoli sprouts which are 20 times more powerful, in helping to ease stress levels.
Eating seaweed, or taking spirulina since it is rich in essential minerals the body needs and even more so if you live away from ocean where these trace minerals are harder to come by.
Resulting in more instances of hypo or hyper thyroidism, gout and hormone imbalances in these regions its almost of epedemic proportions. Physical and mental imbalances becoming even more prominent for those who are either menapausal, pregnant, going through puberty or simply menstrating.
As a reflexologist, i see and am keenly aware of these defeciencies which are becoming more and more common.
Back to the topic of what foods to eat;
Flaxseed or oil will bind and flush toxins from the intestinal tract and without sounding redundant it is also great for balancing the hormones as is evening primrose oil.
A recent article I just read says 'adding flaxseed to cottage cheese' effectively gives a boost to unhealthy or dead cells and regenerizes them, almost like what a cable boost does to a car.
Lemons in water will alkalize the body and release enzymes that convert toxins so they are water soluble.
Lastly eating apples as they are high in fiber and minerals as well as many other phyto-nutrients.
These are just some of the helpful natural alternatives out there that you can find to elieviate your symptoms caused by nutrient deficiencies.
