Men's hormones Recent researchinvestigating cognition in men suggests that, just like in women, gonadal hormones influence mood and behaviour. In particular, low levels of testosterone can lead to an age-related condition called andropause. Credit: AI-generated image (disclaimer) Andropause is sometim...
precipitation, humidity, and sunlight duration. Mounting evidence suggests that weather patterns may influence mood, behaviour, and overall mental well-being. Higher ambient temperatures have been associated with an increased suicide or self-harm burden [68,211,212], mental health-related mortality, an...

Vertebrates indicate their genetic sex to conspecifics using secondary sexual signals, and signal expression is often activated by sex hormones. Among vertebrate signaling modalities, the least is known about how hormones influence chemical signaling. Our study species, the red-sided garter snake (Thamno...
As soon as your brain senses danger, it goes into fight-or-flight mode and sends orders to outposts in the adrenal and pituitary glands to mobilize the hormones adrenaline and cortisol. These in turn send reinforcements to different areas of the body to increase blood pressure, heart rate,...
Stress is a major factor involved in influencing the way a normal body works. It affects the production, regulation, and maintenance of hormones. It can be classified as internal or external, and it relates to emotional, physical and mental circumstances that put a strain on th...
Engaging in regular physical activity like cycling releases endorphins, often referred to as "feel-good" hormones, which help to reduce stress, anxiety, and depression. The rhythmic nature of cycling can also have a meditative effect, allowing you to clear your mind and focus on the present ...
The most extensively studied dimorphic trait in humans is facial dimorphism. While some sexually dimorphic facial traits are mediated by prenatal exposure to sex hormones7, dimorphism reaches full expression after puberty, due to the influence of androgens and estrogens8,9. High levels of testosterone...

emotions can also be influenced by other factors such as the food we consume and our physiology. If we consume healthy food like chicken, eggs, seaweed, bananas, we will have sufficient amino acids to build happy hormones like dopamine and serotonin, which will help to elevate our overall moo...
