In these autumn months, it is a perfect time to start to gather your energy, so you have plenty to carry you through the darker, deeper months of winter. Just as during the harvest festivals, where we celebrate the abundance of harvest and store/freeze/can/preserve what we need until the bounty returns next year; your energy system mirrors this natural occurrence.
There are some wonderful physical/energetic and nutritional aids that you can bring in at this time of year to help the transition from the yang-fuelled summer months into the cooler autumn months, and it feels important to understand what happens energetically as you move through the seasons.
Hopefully, wherever you are, you have had the opportunity to stock up on the amazing abundance of sun energy that was plentiful in Europe this summer. Vitamin D is carried into your whole-body system, firstly through your aura, and then your skin, and this is also how you bring in the vital yang energy of the sun. From October to March, the sun is not strong enough or high enough in the sky to allow the vitamin D conversion in the skin to take place, and so for some people it will become important to supplement with Vitamin D as you progress further into the colder months. But for now, as long as you were able to spend time outdoors over the summer and expose your bare skin to the sun, your natural stocks of Vitamin D should be plentiful.
When I worked in clinical practice, I used to start testing clients to see if they needed vitamin D supplements in January, but most did not need it until February or March when their stores had become depleted and weather conditions weren't yet right to top up their levels naturally.
