The seasons when hemorrhoids are more likely to have acute attacks would be winter and summer. The dry air and less movement in winter may lead to dry stools and constipation in patients. In addition, the cold weather in winter may cause spasms in the blood vessels within the hemorrhoids, thus aggravating the stasis of the hemorrhoids, both of which may lead to acute attacks of hemorrhoids in winter. The heat and loss of water in the summer may also lead to dry stools and constipation. In addition, patients sweat more in the summertime, especially some people with deep buttock grooves, which can lead to severe dampness around the anus, potentially leading to an acute attack of hemorrhoids. So, no matter what season it is, usually hemorrhoid patients should eat more vegetables and fruits, drink more water, keep their bowels open, and need to pay attention to the cleanliness of the anal area after pooping.
