Trees Provide Habitat for Wildlife. It is only natural that wherever trees are planted, wildlife and other plants are sure to follow. Trees provide shelter and food for a variety of birds and small animals, such as squirrels and beavers.
The only real medical reason you could be unusually tired during your period is if you have anemia, which is an iron deficiency. For some women who are anemic and have a very heavy period, the first day can be a doozy. However, this group is in the minority.
During the womanâs menstrual cycle these cells are influenced by the hormone production and imbalance. Endometriosis can cause nausea, bloating, diarrhea, rectal pain, and abdominal cramping. Perhaps the most common symptom of endometriosis is not the nausea but debilitating pain. Endometriosis can be so severe that it can require surgery and perhaps a full hysterectomy. However endometriosis is not the primary cause of nausea during periods.
