Protective measures of electromagnetic allergy

For the low-frequency electromagnetic field, it is suggested to adopt the method of "careful avoidance", that is, to determine the field, find out the source and reduce the exposure. Measure 1: detect the electromagnetic field in the environment. The second measure: reduce exposure to electromagnetic waves. The third measure: stay away from electromagnetic waves and have a good sleep. The fourth measure: effectively isolate the external invasion of electromagnetic waves.
