The warning signs to monitor for sunshine deficiency

Sunlight is essential for your health—boosting mood, strengthening bones, and supporting overall wellness. However, many people unknowingly suffer from sunlight deficiency, especially during the colder months. Here are six warning signs to look out for and tips to safely enjoy the sun’s benefits.
1. You’re feeling moody or depressed
If you’re feeling down during winter, it may not just be the weather. Lack of sunlight reduces serotonin levels, which can trigger seasonal affective disorder (SAD). A daily dose of sunlight—or even blue light therapy—can brighten your mood.
2. You’re gaining weight
Low sunlight exposure affects vitamin D and nitric oxide levels, slowing metabolism and encouraging weight gain. Studies also link vitamin D deficiency to reduced energy production and muscle weakness. Boost your metabolism by exercising outdoors to soak up those rays.
3. Your bones ache
Achy bones and stiff joints might signal a vitamin D deficiency caused by lack of sunlight. Without enough vitamin D, your body struggles to absorb calcium, increasing the risk of conditions like osteoporosis. Spend time outside to keep your bones healthy and strong.
4. You’re exhausted and not sleeping well
Sunlight helps regulate your circadian rhythm, ensuring better sleep quality. Insufficient sunlight can disrupt this internal clock, causing fatigue and even insomnia. Step outside during the day to reset your rhythm and boost your energy levels.
5. You keep getting sick
Sunlight exposure enhances immune function by stimulating the production of immune cells. If you’re frequently battling colds or infections, a lack of sunlight might be to blame. Just 10 minutes of sunlight can boost your immunity and protect you from illnesses.
6. You’re overusing sunscreen
While sunscreen is vital for preventing skin damage, too much can block the absorption of UVB rays needed for vitamin D production. The Skin Cancer Foundation suggests 10-15 minutes of unprotected sun exposure two to three times a week to balance safety with health benefits.
Safe sunlight tips
You don’t need blazing heat or clear skies to benefit from sunlight. Even on overcast days, UV rays can penetrate the clouds and help you meet your vitamin D needs. Prioritize moderate sun exposure to stay healthy and energized all year long.
