      Biological influences on mental health

      Lesson details

      Learning outcome

      I can describe a range of physical health factors that may influence mental health.

      Key learning points

      1. Puberty and menopause can affect mental health.
      2. Infertility and chronic illness can affect mental health for many members of a family unit.
      3. Postnatal depression can affect parents, and it can begin many months after giving birth.
      4. Looking after our bodies cannot always avoid periods of low mental health - this is no one's fault.

      Keywords

      • Biological - related to living things and life processes

      • Stigma - being judged or treated unfairly just because of a particular characteristic, situation or condition, like having a mental health condition

      • Support - the actions taken to help someone who is in a difficult or dangerous situation, such as providing care and seeking medical attention

      Common misconception

      Mental health and physical health are not linked.

      Mental health and physical health are closely linked. When our body feels strong, our mind tends to feel strong too.

      Teacher tip

      This lesson touches upon many challenging scenarios, including postnatal depression and chronic illness. Ensure that you're aware as far as possible of any triggering circumstances amongst your pupils before delivering the lesson. Provide clear signposting to further support as needed.
