Most of us spend hours indoors without realizing that lack of sunlight may silently affect both our mind and physical health. Several research reports indicate that sunlight helps increase serotonin, the brain chemical linked to feeling calm and happy. Without enough of it, especially in winter, many people experience Seasonal Affective Disorder (SAD), a form of depression triggered by low light exposure (JAMA Psychiatry, 2018).
But that is not all; sunlight is also important for making vitamin D, which supports your bones, immune system, muscles, and even heart health. Low levels have been linked with fatigue, bone weakness, poor sleep, and higher risk of chronic illnesses (The Lancet, 2021).
So how much of sunlight do we need? Experts suggest 10-30 minutes of direct sunlight on the skin (like face, arms, or hands) at least 3-4 times a week, ideally during mid-morning or early afternoon, when the sun is not too harsh. The exact amount can vary by skin tone, location, and also season.
Do you notice changes in your mood, sleep, or energy during seasons with less sun?
How much sunlight do you actually get each week?
What easy habits could help indoor workers, students, or shift workers get healthier sun exposure?
Absolutely. I’ve noticed how just a short walk in the sun can instantly boost my mood and clarity. With busy schedules, it’s easy to forget how essential natural light is. I’m now trying to take short sun breaks during late mornings just 10 to 15 mins near a window or stepping outside between tasks. It really helps. We often underestimate how sunlight is nature’s free medicine.
Many people spend their days confined to office cubicles, which can lead to less exposure to sun. Thankfully, more companies are starting to take notice! They’re encouraging their employees to step outside for a refreshing stroll in the sun every now and then. It’s a simple yet effective way to boost morale and promote well-being during the workday!
I definitely observe my mood sliding throughout prolonged periods of grey skies. Just taking a stroll outdoors on a beautiful day often seems to lift up my mood.
Perhaps schools and businesses could offer some regular sun breaks or perhaps walking meetings that encourage people to spend some time outdoors.
@manishakalita I completely agree. These sorts of breaks should be there, as that can largely help towards a healthy mind and also will play a role towards maintaining a good physical health.
@Ayushi32 Seasonal Affective Disorder is a very common issue (sadness during rainy and winter, when sunlight doesn’t come often) and happens to many. Try spending some time under warm tone yellow light at night or anytime when you can as that can hugely help. Have a check on your vitamin D levels, and gut health, as these two can help in the formation of necessary hormones in ample amount to protect against any low mood or sadness during this time.
Yes, I do feel more tired and low during days with less sunlight. I don’t get much sun regularly, especially during busy weeks indoors. I think simple habits like short morning walks, sitting near windows can really help us get the sunlight we need.
I have observed that my physical and mental health are significantly improved by a decent amount of sunlight every day, around an hour is usually sufficient. Indoor workers could take chort breaks to expose themselves to as little as 20 minutes of sunlight for some benefit.
@caryn Thank you for sharing your personal experience and yes, both physical and mental health can drastically improve within a month through optimal sunlight doses. 10-12 mins of sunlight per day is enough for the vitamin D production.
Yes during winter we do feel bit more lazy than in summer
It depends upon how much your body ask for and it’s not like medicine that this is the dose you have to take , it’s like take sunbath as much as you want
For kids playing outside and for adults just take sun bath or walk in morning sunlight that will help
@Prajal I liked this explanation very much. You have put it in such simple words. But sometimes, longer durations of sunbath in high intensity sunlight (between 11 am- 2 pm) can be harmful for skin in long run, causing melanoma (skin cancer). If one wants to stay longer in the sun, they can use proper sunscreen or sun block and this should be done very few a times per month without making it a regular routine. Research says, 10-12 minutes of sunlight in the arms just 5 days a week is enough for optimal health.
