EMFSA Environmental Health Update: July 2026

The EMFSA Environmental Health Update: July 2026 brings together research, regulation, and reporting across electromagnetic fields, climate, and public health. From electrical safety hazards facing children to Italian court rulings on the precautionary principle, this edition covers a wide range of topics relevant to environmental health in South Africa and beyond.

Children and Electrical Safety

Our lead story examines electrical hazards facing children that extend far beyond wall sockets. From button batteries in greeting cards to lithium-ion fires in e-scooters, the risks span everyday products, wearable tech, and viral social media trends. This article synthesizes recent medical case reports, regulatory updates, and safety guidance — from water safety to e-bikes, LED illumination, and social media challenges.

Mobile Network Exposure Follows Human Activity

A new study tracking RF-EMF exposure across ten European countries found that mobile network radiation rises and falls in lockstep with human activity. Nighttime levels dropped by up to 48% compared to daytime peaks. Over 17 months of continuous monitoring, researchers documented predictable daily cycles and modest weekend dips. It’s a reminder that a quick spot measurement can miss the bigger picture. [Read a breakdown of the study.]

Heat, Climate, and Technology

This month’s newsletter explores three interconnected climate stories.

• First: heat domes in the U.S. Midwest are creating atmospheric conditions causing radio, TV, and microwave signals to travel hundreds of miles farther than usual — disrupting communications across the region. 
• Second: data centres contribute to localized “data heat islands” with significant environmental impact, warming land around them by up to 16°F. 
• Third: extreme heat events are triggering new liability trends in insurance, with engineers potentially facing professional liability claims where infrastructure design proves inadequate.

Nature, Tranquillity, and Public Health

Two studies reinforce the importance of considering not only environmental hazards but also the health benefits of restorative environments. A review in Noise & Health proposes tranquillity should be regarded as an environmental determinant of health. Another experimental study found that both restored forest and birdsong promote psychological well-being. These findings have particular relevance for South Africa, where access to safe, well-maintained green spaces remains limited in many townships and underserved communities.

The Precautionary Principle in Consumer Law

Italy’s Supreme Court (Court of Cassation) issued a new ruling on manufacturer responsibilities. Manufacturers may now have a duty to warn consumers when scientific uncertainty surrounds potential risks.

The decision shifts focus from proven harm to informed consumer choice. Companies must provide sufficient information even when risks remain unproven.

Importantly, the ruling does not establish that mobile phone RF exposure causes disease. However, it acknowledges that scientific uncertainty does not remove the need for precautionary information where potential risk cannot be excluded.
