The Role of Hormones in Human Behaviour

Endocrine System

• This system comprises of glands that secrete hormones directly into the bloodstream.
• These hormones can influence our mood, metabolism, growth and development.

Oxytocin

• Often referred to as the ‘love hormone’. It plays a vital role in social bonding, sexual reproduction and during and after childbirth.
• Oxytocin can also stimulate empathetic responses and improve mood.

Cortisol

• Known as ‘stress hormone’. It helps the body respond to stress effectively.
• High levels of cortisol over a prolonged period can lead to anxiety and depression.

Adrenaline

• It prepares the body for ‘fight or flight’ response. This hormone increases heart rate, blood pressure and boosts energy supplies.

Testosterone

• Found in both sexes, but men have higher levels. It’s related to aggression, sexual drive, dominance, and physical strength.

Estrogen and Progesterone

• Primary female hormones, critical in menstrual cycle, pregnancy and menopause.
• They have significant effects on mood and are linked to premenstrual syndrome (PMS).
