In 1967 the humanistic psychologist Dr. Sidney Jourard made an informal study of touch. He travelled to several countries observing how many times people touched one another in informal settings... In Puerto Rico he counted 180 touches an hour between two people. In Mexico City it was 185. In Paris it was 115. In Florida it was two and in London it was a big fat zero.
In the winter we have to go against our natural inclination to reduce our activity levels as its dark and miserable in the outside, as well as endeavouring to be more disciplined in our eating patterns - despite the encompassing festive season - aiming to keep evening and night-time carbohydrate intake low, especially those of the simple variety e.g. white pasta, white bread, white rice, baked/roast potatoes, baked goods, soft drinks, desserts etc, to reduce insulin demand. For serious cases of rhythmic misalignment bright light therapy can also be used.
