Balancing the Ayurvedic Medicine's Constitution of Vata can help increase mental clarity, inspiration, balanced energy in the day and rest at night, regulated digestion, as well as many other strengths. Fall is the time of Vata and with that can come Vata imbalances. Using different oils to warm and moisten one's system is optimal.  Oils such as Sesame or olive oil are very nourishing during the dry season, sesame is also warming as the weather turns colder.
    Regular exercise and a regular schedule helps to regulate Vata.  Exercises such as Yoga or Tai Chi help balance the Vata elements of Ether (space) and Air. It is helpful to hold the yoga poses for longer periods of time when balancing the wind like movements of Vata. Grounding, resting, staying warm all help with this King of a Dosha, constitution.  Vata is the constitution of the Fall season.

Be well.

According to Sage Patanjali (sutra 2.50), "Modifications of the breath are either internal, external or stopped; they are to be regulated by space, time and number and are either long or short". In this context space represents either a specific point of focus within the body (e.g. lower spine) or the left/right nostril, time means the duration of the breath and number means the number of inhalations and exhalations or retentions. Following these guidelines, a large number of breathing techniques have been documented in the Hatha Yoga Pradeepika, the ancient text on Hatha Yoga. Over the years, many new techniques as well as different variations on the classical techniques have emerged and are widely practiced.
