While we often hear about the dangers of too much sun exposure, it is rare we discuss the major health benefits of getting enough sunlight day-to-day. If you’re a nurse who works frequent night shifts, you may be wondering how you can still get your dose of serotonin if you’re not seeing the sun as much as the average Joe. In this blog, we offer some suggestions, as well as serving a reminder of why sunlight is so important for us.
Why is sunlight important?
Research has suggested that exposure to sunlight can help boost serotonin levels (regulating your mood and concentration). On the other hand, melatonin is released at night to help you sleep. However, when we don’t get enough sunlight our brain can produce less serotonin, which can lead to feelings of unhappiness and even depression in some cases. This is why low moods are often connected to the changing of the seasons (e.g. SAD).
Additional benefits:
Vitamin D: Sunlight is a natural source of vitamin D, and exposure to sunlight helps the skin produce this essential vitamin. Vitamin D is crucial for maintaining strong bones, supporting the immune system, and promoting overall health.
Improved sleep: Exposure to natural light, especially in the morning, can help regulate the body's internal clock (circadian rhythm), leading to better sleep patterns and improved sleep quality.
Skin health: Moderate sunlight exposure can benefit skin health by helping to alleviate certain skin conditions, such as psoriasis, eczema, and acne
Cancer prevention: Adequate vitamin D levels, obtained through sunlight exposure, have been associated with a reduced risk of certain cancers, including breast, colon, and prostate cancers.*It's important to note that while sunlight has numerous health benefits, excessive sun exposure without proper protection can lead to skin damage and increase the risk of skin cancer.
I’m working night shifts…how can I still get the benefits of sunlight?
If you’re asleep during the day ahead of your late night shift, you might be wondering how you can still get the health-boosting benefits of sunlight and keep your serotonin levels strong. One solution is something known as ‘light therapy’ or ‘phototherapy’ where you can get the same benefits from a lightbox as you do from the sun. This will help trick your brain into creating serotonin and cut down on excess melatonin. If you are frequently working nights it may also be worth taking vitamin D supplements. Some people also recommend blue-light blocking glasses to maintain a consistent circadian rhythm.
