Women's hearts are said to bloom like flowers in spring and now this long-held belief seems to have a scientific basis as the sunshine at this time of year can effect their hormones.
The longer daylight hours increase the secretion of serotonin, which makes people happier and more motivated. There is a spike in the chemical when the season changes from winter to spring, and women, who tend to be more sensitive to emotional changes, usually show a stronger reaction. However, such dramatic mood swings can also make them more vulnerable to feelings of depression.
On the plus side, the spring sun generates more estrogen to women's inflame passions, while on the down side, the bigger swings in temperature between day and night can trigger violent shifts in mood and cause fatigue.
Flowers also play a part in women's changing moods. The bright colors of spring flowers can cause their hearts to flutter, but as they wither away the corresponding emotion can often be close to melancholia.
This spring women will likely enjoy happier days as the weather is forecast to be much warmer than in previous years. Due to the unusually warm weather, cherry blossoms came in full bloom 13 days earlier than usual in Seoul.
