Avoiding Prolonged Indoor Living Without Natural Light

Extended indoor living devoid of natural light and fresh air can significantly impact health. The studies referenced [4, 5, 19] show how reduced sunlight and inadequate indoor conditions contribute to reduced vitamin D levels, which are vital for both physical and mental well-being. During the COVID-19 pandemic, limited sunlight exposure led to vitamin D deficiencies in children, highlighting a vulnerability to associated health issues as evidenced by studies such as [3] and [18]. Moreover, poor indoor air quality, as discussed in references [9, 13], further compounds these health challenges, affecting respiratory health and cognitive function.
