Why should you turn off wifi at night?

How many of you find yourselves sleeping with the phone next to your head and with the wifi constantly on? Have you ever thought switching wifi off for the night could be part of the solution, leading to better health of your family?


Electromagnetic fields (EMFs), also called radio frequency, emitted from wireless devices can affect your health. With wifi being one of the main sources of EMFs in your home, switching it off at night could be a simple step to help you get a healthier sleep and to reduce your exposure by a third.

Let us explain why.

If you are new to the topic of radio frequencies, microwave radiation and EMFs, start with our article titled The Beginner’s Guide to Electromagnetic Radiation

Done it? 


Then let’s answer the main question and have a look at the Bioinitiative report on the effects of EMFs on health. Compiled by 29 independent scientists and health experts from around the world, this report is only one of many reliable resources available online that shows evidence of the effects and possible risks from wireless technologies and electromagnetic fields.


According to this report, bioeffects (effects on the human, animal or cell biology) are clearly established and take place at very low levels of exposure to electromagnetic fields and radiofrequency radiation, be it from a mobile or cordless phone use, mobile phone masts, WI-FI, and wireless utility ‘smart’ meters that produce whole-body exposure. 


Studies quoted in the report show that these exposures can not only cause DNA damage, but can also cause oxidative stress (think faster ageing and disease) and can be carcinogenic. There have also been studies showing the impact on sperm function, brain and the nervous system as well as behaviour in offspring.


So the more we are exposed to these fields and wireless radiation, the more the body needs to keep up to keep everything in check and combat this source of stress.


This is exactly why switching off your wifi during night time is one of the very simple things to do to help combat the issue of EMFs. It is not the only solution, but reducing the exposure time by 7 or 8 hours a day, where possible, is definitely worth it.


Tips to help you sleep better

How does blue light affect your sleep?

Have you ever found yourself staring at a computer screen for hours, working, studying, browsing or watching a movie? You would stay up until very late, only to find yourself wide awake as soon as your head hits the pillow.

Although there are a few key things that can impact your sleep quality (link to blog), how much time you spend using your wireless devices is one of the major influencers of how well you will sleep.

And it is mainly because of blue light.

Are all EMFs (Electromagnetic Fields) harmful?

Interested in keeping your family healthy? If so, the chances are you’ve come across the term ‘EMFs’ (Electromagnetic fields), specifically in connection with mobile phones, wifi routers, laptops or smart meters. Due to their unfavorable impact on our wellbeing, the reputation EMFs have earned is very much a negative one. 

But are they all the same? Are they all harmful?

The answer is NO. They aren’t.

What is mobile phone Specific Absorption Rate (SAR): safety and health concerns

Both you and I are only two of the five billion mobile phone users out there. Our phones have become a daily necessity for us. Have you ever wondered how much radiation you absorb when making a phone call, downloading a file or simply when keeping a phone in your pocket? How safe is it? And how did SAR come about?

Microwave Emissions from Mobile Phones Exceed Safety Limits

In his scientific report from early 2019, Prof. Om. P. Gandhi shows that mobile phones fail the Specific Absorption Rate (SAR) safety limits both in Europe and the USA. He recommends that the regulators change current compliance testing methods.

As consumers, we generally think that all electronic products we use, including mobile phones, are safe to use.  When it comes to mobile phones and other wireless technology, one of the safety tests that a product needs to pass before it’s released to the market is a Specific Absorption Rate (SAR) test. The results of such test reveal whether the product is above or below a set safety limit.

Prof Gandhi reveals that the current safety standards and the way these tests are carried out are not providing us, the consumers, with true results. And because of that, we can’t rely on them. We’ll explain why.

How harmful is radiation?

This question is frequently asked of our customer service team. To answer this question, we have to distinguish between the different sorts of radiation. Most of these, e.g. radioactive radiation or low-frequency electromagnetic fields, are accurately graded and classified and their effects known. So we know precisely the levels above which they become harmful, and what we can do about it.
