Have ever noticed that you feel yourself better, more energized, less stressed and faster in loosing extra weight in a particular season every year? There is a scientific explanation for that! A recent large Israeli study found that we have an internal seasonal(!) clock, which somehow lines up our hormones with the seasons!

According to the study, we, humans, like other mammals, may have a physiological peak season for our basic biological functions. A review of millions of blood tests has shown that our different hormones fall into clear seasonal patterns, although these changes are small in magnitude.

The study showed that hormones from the pituitary gland, which help control reproduction, metabolism, stress and lactation, were mostly found to peak in late summer. Peripheral organs that are under the control of the pituitary, like those that produce our sex hormones or the thyroid hormone, are on their highest level in winter. Testosterone, estradiol, and progesterone, on the other hand, reach their highest level in late winter or spring.

Why this alignment between our hormonal changes and the nature seasons happens is still to be investigated. But the researchers believe that there is a natural, year-long feedback loop between the pituitary gland and peripheral glands in the body. For example, the pituitary hormones, which are uniquely tuned to sunlight, could be feeding the other organs over the course of a year, allowing them to grow in functional mass in a way that aligns with the seasons.
