Mobile phone radiation: what the SAR value means

The smartphone is our closest companion, often closer to the body than any other device. That is why it is worth knowing how it transmits and how to reduce exposure with little effort.

How does a phone emit radiation?

A phone only transmits when it exchanges data: during calls, browsing or background updates. How strongly it transmits depends mainly on reception. With a good connection to the base station it can reduce its transmission power considerably; with poor reception it transmits more strongly.

What is the SAR value?

The specific absorption rate (SAR) indicates how much radiation power the body absorbs, measured in watts per kilogram. It is determined for each model under the least favourable conditions. The limit for head and body is 2 W/kg.

What you can do yourself

1. Keep your distance. Radiation decreases quickly with distance. Even a few centimetres make a difference.
2. Use headphones. Wired and Bluetooth headphones have a SAR value many times lower than the phone itself.
3. Wait while connecting. Only hold the phone to your ear once the call is connected.
4. Avoid poor reception. In trains, lifts or basements, prefer writing messages to calling.
5. Don't charge next to your pillow. Charge your phone outside the bedroom at night or use airplane mode.

Less screen, more calm

Whether radiation or constant notifications: our nervous system needs breaks. Your phone's focus mode, fixed offline times and a classic alarm clock are simple steps towards calmer evenings.
