The wind is whipping around outside and can cause our Vatta (one of the three doshas, or constitutions of our body in Ayurveda) to become out of balance. This causes us to feel confused, out of sorts and possibly even develop sickness.
To restore balance:
1) Drink warm fluids
2) Use more spice in your cooking
3) Keep your head covered outdoors.
4) Take time for self care, even if it is something as simple as wrapping yourself in a warm blanket, sipping some tea and doing some deep breathing exercises.
