Hormones

• Stress - When we experience stress, our bodies release hormones like epinephrine (adrenaline), cortisol, and norepinephrine.
• Cortisol helps your body respond to stress, regulate blood sugar, and fight infections. 
• Increased stress leads to increased blood pressure and heart rate, muscle tension, and the digestive system slamming to a halt, resulting in nausea, vomiting, and diarrhea.
• Moods - production of serotonin – serotonin is a hormone that affects your mood, appetite and sleep; a lack of sunlight may lead to lower serotonin levels, which is linked to feelings of depressios
• Sleep - Melatonin plays an important role in regulating human sleep
• Relationships - oxytocin's role in various behaviors, including orgasm, social recognition, bonding, and maternal behavior. 
• Happy hormone - Dopamine: Often called the "happy hormone," dopamine results in feelings of well-being. A primary driver of the brain's reward system
