For many people, the holiday season brings up all kinds of anxiety and stress triggered by the thought of family gatherings, relationship, finance, expectations of others and expectations of your Self, the physical, mental and emotional demands of entertaining or being social when perhaps you are not feeling up to it. These physical, mental and emotional demands can deplete your energy reserves and compromise your immune system making you more susceptible to colds and flu which is the last thing you want for holidays.
From the perspective of body-mind-heart-soul health and wellness, the following are some helpful tips to minimize your anxiety and stress levels on all four levels of your being through the holidays :

Physical Level: Make sure you take extra good care of your physical body during the holidays:

Recently, I came across one of the most insightful young men in the consciousness movement I have come across, Leo Babauta, creator of the critically acclaimed Blog Zen Habits, named best blog of 2010, by Time Magazine. I am honored to be able to offer Leo Babauta's second e-book, the Zen Habits Handbook for Life — a series of his best articles on making your life simpler, on becoming happier, and on getting more productive.
Leo put this e-book together at the request of a number of readers, who wanted the essential Zen Habits articles gathered in an e-book format. I’m certain you’ll enjoy it!
What will this book teach you to do? Basically the same things that Zen Habits aims for overall: how to simplify your life, how to live a happier life, how to be more productive with less stress, how to achieve your dreams. Think of it as a little handbook for a better life, in a convenient e-book format.

Emotional Level: The holiday season brings up “triggers” in everyone. Understanding that you are not alone in feeling anxious or stressed, will help you to be more tolerant of others when they act or say something that feels abrupt, hurtful or inconsiderate.

Spiritual Level: Bring purpose and meaning into your holiday experience. Spirituality is personal to each person and even the agnostic can look for deeper meaning and connection to one Self and others from a philosophical perspective.
