With my local supermarket requiring you to use sanitiser in these times, along with anti-bacterial wipes being around the place; I have noticed that after using these types of products, I get a headache very quickly.
At work we currently have two products that I use "when needed"
E-Vap, Instant Hand Sanitiser 485ml (contains 720g/litre Ethyl Alcohol)
Reynard Health Supplies Premier Disinfectant Wipes (Alcohol and Fragrance Free)
Both cause headaches, the E-Vap is slightly quicker (8 minutes vs 11) and both last for approx 30 minutes
So, before I Google does anyone know what could cause this (I am obviously not going to ask a doctor ..)
