I've been dealing with a bad cough for about a week now and I already took azithral for 5 days once a day. The thing is, for the past 3 days, I've noticed that my morning sputum has streaks of blood in it, even though the cough has gotten a bit better but it's not totally gone. Today, I actually felt a little dizzy while working. My appetite seems pretty normal, it's even increased a bit compared to before. Also, I do smoke quite a bit. Could you advise me on what might be going on or what I should do?

Vitamin D Absorption from Sunlight

Morning Sun vs. Evening Sun

1. UVB rays: Vitamin D is produced in the skin upon exposure to UVB rays from the sun.
2. Morning sun: UVB rays are more intense during morning hours (7-10 am), making it a better time for vitamin D production.
3. Evening sun: While some UVB rays are still present in the evening (4-6 pm), the intensity is significantly lower, making it less effective for vitamin D production.

Tips for Vitamin D Production from Sunlight

1. Expose skin: Expose your face, arms, and legs to sunlight for 10-15 minutes, 2-3 times a week.
2. Avoid peak hours: Avoid sun exposure during peak hours (11 am-3 pm) to minimize skin damage and skin cancer risk.
3. Supplement if necessary: If you're unable to get enough sunlight or have a severe deficiency, consult your doctor about vitamin D supplements.

Remember to always practice sun safety, such as seeking shade, wearing protective clothing, and applying sunscreen with at least SPF 30.
