Why you need to avoid excessive sunlight

Nairobi, the bustling capital of Kenya is blessed with a tropical climate that brings forth warm and sunny
days for most of the year. However, for the past few days, temperatures have gone up due to excessive sunlight.

Excessive exposure to sunlight can have far-reaching effects on the health and well-being of its residents. As the sun’s rays become increasingly intense due to global climate change, it is crucial to understand the potential consequences and take necessary measures to mitigate their impact. Here are some of real-time quick facts on sun effects.

Sunburn and Skin Damage
This occurs due to prolonged exposure to ultraviolet (UV) radiation. With an increased intensity of sunlight, the risk of sunburn and skin damage rises significantly. Overexposure to UV rays can lead to painful burns, premature aging, and an increased risk of skin cancer. To avoid this, individuals must take measures like wearing hats, sunglasses, and using sunscreen with a high SPF regularly. It is of importance to note that there are some sunscreens that are not good for skin. These are mostly counterfeited products but are branded as legit ones. So one must be cautious when buying one because it can cause catastrophic effects.

Dehydration and Heat-related Illnesses
Excessive sunlight and soaring temperatures can contribute to dehydration and a higher risk of heat-
related illnesses. Nairobi residents, particularly those who work outdoors or engage in physical
activities are susceptible to heat exhaustion and heatstroke. Symptoms range from fatigue and
dizziness to nausea and in severe cases, organ failure. Adequate hydration, seeking shade during peak
sunny hours and taking frequent breaks in cool environments are crucial to prevent such illnesses.

Eye Damage
Intense sunlight also poses a threat to eyes. Prolonged exposure to UV radiation can
cause various eye conditions, including cataracts, macular degeneration, and photokeratitis (sunburn of
the cornea). These conditions can lead to vision impairment or even permanent blindness. Wearing UV-
protective sunglasses and wide-brimmed hats can significantly reduce the risk of eye damage caused by
excess sunlight.

Vitamin D Deficiency
While excessive sunlight can be harmful, it is essential to strike a balance, as sunlight is also the primary
source of vitamin D. In Nairobi, where many people spend a significant portion of their time indoors due
to work or other commitments, lack of exposure to sunlight can lead to vitamin D deficiency. This
deficiency can result in weakened bones, increased susceptibility to infections, and even mental health
disorders. A sensible approach would be to seek moderate sun exposure, especially during the early
morning or late afternoon when UV rays are less intense.

Impact on Mental Health

The scorching Nairobi sun can have an indirect impact on mental health as well. The relentless heat can
cause discomfort and irritability, affecting individuals’ overall well-being and productivity. Additionally,
extended periods of hot weather may exacerbate feelings of restlessness, anxiety, and depression.
Encouraging the use of cooling systems, maintaining hydration, and promoting indoor activities during
peak sun hours can help alleviate the adverse effects on mental health.

Excess sunlight in Nairobi brings both benefits and challenges to its residents. While enjoying the
warmth and beauty of sunny days, it is crucial to acknowledge and address the potential health risks
associated with overexposure to the sun’s rays. By adopting preventive measures such as sun
protection, staying hydrated, and seeking shade, Nairobi residents can minimize the adverse effects of
excessive sunlight on their skin, eyes, and overall well-being. Striking a balance between sun exposure
and protection is key to embracing the sun while safeguarding our health in this vibrant African city.
