Seasonal Affective Disorder (SAD) is a type of depression that typically occurs during the fall and winter months when daylight hours are shorter. It’s thought to be triggered by reduced sunlight, which can disrupt the body’s internal clock, lower serotonin levels (impacting mood), and affect melatonin production (which regulates sleep). Common symptoms include low energy, oversleeping, changes in appetite (especially cravings for carbs), and feeling depressed or withdrawn. People with SAD often find relief through light therapy, exercise, outdoor time, and other supportive practices. This is around the time that I make sure I double up on my Vitamin D3 supplementation, but make sure to take Vitamin D3 with K2. #seasonaffectivedisorder #sad #nurse #nursepractitioner
