Public health experts are urging Nigerians to make regular exposure to sunshine, particularly early morning sun, a part of their routine.
According to these experts, soaking up the sun can help lower blood pressure levels and even reduce mortality from cardiovascular issues.
Studies have revealed a link between exposure to sunlight and lower blood pressure levels. It is believed that sunlight triggers the release of nitrogen oxides from the skin, which subsequently expands blood vessels, thus lowering blood pressure. This effect may also have a protective effect against metabolic syndrome.
The experts, including Professor Tanimola Akande from the University of Ilorin and public health physician Dr. David Adetola, highlighted the benefits of sunlight in boosting the body’s vitamin D supply. Professor Akande emphasized the importance of early morning sunlight between 7 am and 9 am for optimal vitamin D generation.
However, the experts cautioned against excessive exposure to sunlight, particularly after 10 am, as it can be harmful. The recommended duration of sunlight exposure is typically 5 to 15 minutes, depending on an individual’s skin type. Dark-skinned individuals may require up to 30 minutes. The use of sunscreen is also advised for prolonged exposure.
Lack of sunlight can lead to vitamin D deficiency, which is crucial for bone health. Exposure to sunlight improves bone health and decreases the risk of diseases in both children and adults.
Additionally, studies have shown that sunlight exposure can reduce blood pressure, increase blood flow, and even alleviate certain autoimmune diseases.
While it is essential to protect oneself from excessive sunlight to prevent skin cancer, researchers argue that limiting sunlight exposure excessively may increase the risk of prevalent cardiovascular conditions.
A study conducted at the Universities of Southampton and Edinburgh demonstrated that sunlight exposure can reduce blood pressure by altering nitric oxide levels in the skin and blood.
Multiple studies have also reported a correlation between increased sun exposure, reduced blood pressure, and lower cardiovascular mortality. Sunlight exposure has benefits beyond vitamin D production. It stimulates the release of nitric oxide, promotes the production of beta-endorphin, and regulates circadian rhythms, all of which contribute to lifelong health and well-being.
In conclusion, these findings emphasize the importance of embracing sunlight in moderation as a means of maintaining overall health, lowering blood pressure, and reducing the risk of cardiovascular issues.
