Eat with the seasons
"During the summer months, we're at the height of yang time; the energy of the body is flowing at its fullest and our bodies are trying to cool down," says Dr Cass.
Traditionally starts around the third week in February and lasts around six weeks.
Just as the temperatures begin to cool down, we need to eat more yang pungent and spicy flavours.
"This is the peak of yin time when everything is cold, both externally and internally, so you want to have very salty yang types of foods to help keep your extremities warm," says Dr Cass.
"As you transition back from yin to yang time and come out of hibernation, this is when sour flavours are best in preparation for becoming more physical in the upcoming warmer months. However, don't overdo it on sour foods because this can also injure the liver," says Dr Cass.
