A good article about how to prepare your body for winter:

"Eat for the winter season. To replenish and store, eat nutritionally dense foods. Root vegetables, dark leafy greens prepared in rich broth soups and stews build blood and repair tissue. Winter is not the time for cold raw foods which are great for spring cleansing and eliminating. Rather winter is the time to deepen the well of nourishment within. Eat seasonal pumpkins, squash, apples, pears and mushrooms warm, simply cooked foods.

Exercise for the Season. Rather than continue the same exercise program throughout the year, fine tune or shift to quieter movements. Qi Gong, tai chi, restorative yoga, continuum movement, all provide an internal exploration fitting for winter. Reflective, the winter season is a time to turn towards your self and nourish your inner creative juices. Nest and prepare for quiet winter gatherings, slow down rather than reeve up for the winter holidays so they reflect the values and traditions dear to your heart.

Winter is a good time for regular acupuncture, massage, acupressure or other healing modalities that restore and rejuvenate. Bathing is a restorative activity, perfect in winter. Taking the time to prepare and immerse your self in a steaming bath encourages relaxation and contemplation."
