We might consider sunlight as the “original” light therapy. We observe and experience for ourselves the physiological, emotional and mental health benefits that sunlight brings to all living things. Conversely, limited sunlight exposure for prolonged periods can create physical, emotional and mental health challenges. This is particularly common during the winter season, when daylight hours are much fewer. For many of us, especially during the colder months, the sun is already setting by the time we have wrapped up the day’s commitments. Indoor UV tanning can help to supplement the natural sunlight that we need to stay healthy in mind and in body.
UV rays have often been associated with improved energy and elevated mood, potentially due to increased serotonin levels. UV rays, in some cases, have also been demonstrated to lower hunger hormones and increase norepinephrine, which is a hormone that breaks down fat and converts white fat, which stores energy, into brown fat, which burns energy. Sunlight, which contains UVB, induces our skin to synthesize the vitamin D3, which is crucial for various bodily functions, including maintaining strong bones, regulating the immunes system, and supporting mental health. Exposure to UVB rays also causes our skin to produce beta-endorphins, which are hormones that help to reduce pain. UVB rays are known to have anti-inflammatory properties that can be beneficial for certain skin conditions, such as acne, psoriasis, and eczema.
Although most of us are somewhat affected by reduced sunlight exposure, certain individuals develop a more significant condition termed, Seasonal Affective Disorder (SAD), which is a form of depression believed to be caused by a hormonal imbalance that is commonly triggered during the shorter days of winter. Generally, levels of melatonin (a sleep-related hormone) in the body are higher at night and lower in the morning. For people with SAD, however, the cycle is often delayed, and melatonin levels remain elevated into the morning, causing them to oversleep or leaving them fatigued. Meanwhile, the brain’s internal clock relies on early morning light to keep circadian rhythms in sync with local time, but the late sunrises of winter deny our bodies that essential signal. Depression can result when we have to keep waking up while it is still dark.
When combined with our powerful whole body red light therapy, our UV indoor tanning sessions can help to increase mood and energy, boost Vitamin D and serotonin levels, and may even reduce symptoms associated with Seasonal Affective Disorder.
When managing symptoms related to SAD, it’s important to also prioritize sleep, a balanced diet and exercise. And, of course, always consult with your doctor or mental health provider before starting any treatment plan for symptoms related to SAD.
