Keeping Cool and Energised. A Functional Medicine Guide to Summer Heat

Functional Medicine

While we all look forward to the brighter days and longer evenings of summer, the rising temperatures can actually place a significant demand on our physical biology. In our clinic, we often see patients who find themselves struggling with unexpected fatigue, digestive issues, and brain fog as soon as the weather warms up.

If you find that the heat leaves you feeling drained rather than energised, please know that this is not just in your mind. There are clear, physical reasons why your body is working overtime to adapt to the season.

What We See in Our Patients During the Summer

When the temperature rises, your body has to work incredibly hard to maintain its core temperature. We often observe a few key shifts in our patients during this time.

Digestive sluggishness and bloating

To keep you cool, your cardiovascular system redirects blood flow away from your internal organs and pushes it toward the surface of your skin. This is why you might look flushed when you are hot. However, because blood flow to your digestive tract is reduced, your stomach acid and enzyme production can slow down. This is why many people lose their appetite in the summer or find themselves struggling with bloating and indigestion after eating meals that they usually digest with ease.

The fatigue of mineral depletion

When we sweat, we do not just lose water. We also lose vital minerals known as electrolytes, including sodium, potassium, and magnesium. Many people try to combat the heat by drinking litres of plain water. While staying hydrated is important, drinking too much plain water without replacing these minerals can actually dilute your system. This dilution can lead to headaches, muscle weakness, and a sense of exhaustion.

Histamine and inflammation flares

For some of our patients, particularly those with autoimmune conditions or histamine sensitivities, the physical stress of heat can act as a trigger. Heat can cause mast cells to release more histamine into the bloodstream, which can lead to increased skin rashes, puffiness, and seasonal allergy symptoms.
