So, to make the most of the vulnerable winter weather sun, timing is critical.

“The best time to step out is in the afternoon, when the sun is at its highest point, making UVB rays surprisingly stronger than early morning or late evening. However, because the winter sun is so weak, a person may also need over an hour of illumination to produce what takes simply fifteen minutes in the summer months,” he adds.

How do diet and exercise help during this time

Daily exercise and diet must be adapted accordingly to overcome the winter restrictions.

“Since the morning sunshine is quite limited, changing your diet would be the most preferable way to prevent a deficiency. One must include rich sources of vitamin D in their meals, such as fatty fish (salmon and mackerel), egg yolks, and UV-exposed mushrooms. Everyday items like milk, juices, and cereals can also help in providing a major boost,” suggests Dr Kumar.

Without enough intake, you may experience severe deficiency symptoms.

“There may be pain in the bones and lower back, muscle weakness, fatigue, hair loss, and increased susceptibility to infections owing to a weakened immune system,” he adds.

People with health issues linked to low vitamin D levels should consult a healthcare professional and consider testing rather than relying on symptoms alone.
