It is sometimes known as winter depression because symptoms are more severe during the winter months. Symptoms often begin in autumn as the days start getting shorter and is usually more severe during the months of December, January, and February. SAD can be a serious mental Illness.

It is thought that the cause, is that the brain is exposed to less natural light & vitamin D during autumn and winter, and this disrupts the brain’s production of melatonin (The sleep hormone) and serotonin ( The mood hormone).  It can also disrupt the body clock.

  • During periods of depression, it is important to try and maintain a balanced diet and active lifestyle.
  • Regular exercise is thought to help as it lifts the mood although this can prove challenging if you are feeling depressed.
