Shutting the sun out of your life is bad for your health. Sunlight is essential for life on Earth as it drives natural processes such as photosynthesis in plants and regulates climate and weather patterns. However, it also benefits your health and mood.
It also boosts your mood by triggering several biological processes that influence mental well-being. Here’s how sunlight helps you feel happier and more energised:
Reduces stress: By being outdoors in sunlight helps lower the level of cortisol, the body’s primary stress hormone. High cortisol levels are associated with feelings of stress and anxiety. By reducing cortisol, sunlight promotes relaxation and reduces tension, leading to an overall improvement in mental well-being.
Combats Seasonal Affective Disorder (SAD): Seasonal Affective Disorder (SAD) is a type of depression that occurs in the fall and winter when daylight hours are shorter. Sunlight helps counteract the symptoms of SAD by increasing serotonin production and improving overall mood. Light therapy, which mimics natural sunlight, is often used to treat SAD.
Boosts Vitamin D: Low levels of vitamin D are associated with depression and mood disorders. Sunlight helps the skin produce vitamin D, which has been linked to brain function and mood regulation. Ensuring adequate sunlight exposure helps maintain optimal vitamin D levels, which can reduce the risk of depression and improve emotional stability.
Increases serotonin levels: Sunlight stimulates the brain to produce serotonin, a neurotransmitter that regulates mood, emotions, and focus. Higher serotonin levels contribute to feelings of happiness and calm. According to Archana Singhal, Counselor and Family Therapist, Founder, Mindwell Counsel, Delhi, “Exposure to sunlight triggers the brain to release more serotonin, which helps improve mood and promotes a sense of calm and focus. This is why people often feel happier and energetic on sunny days.”
Improves cognitive function: Regular exposure to sunlight can improve cognitive function and mental clarity. Natural light increases alertness and enhances brain function, leading to better concentration, improved memory, and clearer thinking. This is partly due to the mood-boosting effects of serotonin and dopamine, which help keep the brain functioning optimally.
Sunlight’s mood-boosting effects go beyond just serotonin production. It also influences endorphins, dopamine, hormonal balance, cognitive function, and immune health. By encouraging outdoor activity, social interaction, and connecting with nature, sunlight creates a holistic sense of well-being that enhances mood and emotional resilience.
