Integrated Body Dynamics

A little word from Rob, Co-Founder and Sports Massage therapist.

Can skin colour determine health issues depending which country we live?

Human beings evolved over thousands of years in very different climates, and these environments helped shape the way we look today. Skin colour, eye colour, body shape, and many other physical characteristics developed gradually as adaptations to the climate conditions in which populations lived.

In regions with strong sunlight, such as much of Africa and parts of Asia, darker skin evolved as a natural form of protection against intense ultraviolet (UV) radiation. Higher levels of melanin in the skin help protect against sun damage and excessive UV exposure.

Similarly, darker eye colours, particularly dark brown eyes, are often better suited to bright sunlight conditions. Over time, these evolutionary adaptations helped human populations survive and function more effectively within their environments.

Today, however, many people live in climates very different from those their ancestors evolved in. In our clinic, we often see clients with naturally darker skin tones who have spent many years living in northern countries such as the United Kingdom.

Over the years, I have personally noticed that many of these individuals do not always appear as healthy or vibrant as they potentially could be, both physically and sometimes mentally.

One thing I frequently observe is that the skin of darker-skinned individuals living in low-sunlight countries can often appear pale, dull, or lacking vitality. Rather than the warm, rich tones usually associated with healthy sun exposure, the skin can sometimes take on a tired or washed-out appearance, almost as though the body is calling out for sunlight.

There is a scientific reason why this may occur.
Darker skin contains higher levels of melanin, which is extremely beneficial in sunny climates because it protects the body from excessive UV radiation. However, melanin also reduces the skin’s ability to produce vitamin D from sunlight.

In countries with limited sunshine, especially during long winters, this can increase the risk of vitamin D deficiency in people with darker skin.

Vitamin D plays an important role in many aspects of health, including:
• bone strength,
• muscle function,
• immune health,
• hormone regulation,
• mood,
• and overall wellbeing.

When vitamin D levels become too low, people may experience:
• fatigue,
• muscle aches and weakness,
• low mood or depression,
• slower recovery,
• reduced immune function,
• and increased risk of bone-related problems.

This does not mean darker skin is unhealthy. Quite the opposite — darker skin is a highly effective evolutionary adaptation for sunny environments. Problems can arise when bodies adapted for high levels of sunlight are exposed to modern northern lifestyles characterised by:
• weak sunlight,
• long winters,
• indoor living,
• office-based work,
• and limited outdoor exposure.

In many ways, this represents a mismatch between ancient biology and modern living conditions.

Today, many health professionals recommend vitamin D supplementation during autumn and winter months, particularly for people with darker skin living in northern climates. While supplements can certainly help, I personally believe that, wherever possible, the body functions best when it can naturally produce vitamin D through healthy sunlight exposure.

My advice for people with darker skin living in low-sunlight countries is to make the most of natural sunlight during the summer months, spend time outdoors whenever possible, and, if circumstances allow, travel to sunnier climates during the darker parts of the year. Sometimes giving the body access to the environment it evolved for can have a profound effect on both physical and mental wellbeing.

People of all skin tones should use appropriate sun protection when spending prolonged periods in strong sunlight, particularly in very hot climates or during sunbathing.

And unlike me keep safe do not sunbathe in the middle of the road.
