Slow loading pages increases users' blood pressure: Study

Other reasons for major increase include pop-up ads, auto-play music and broken pages

Slow loading pages increases users' blood pressure: Study
According to a study by UX agency Cyber Duck, slow loading pages cause website users the most stress and see a 21% increase in their blood pressure. Average blood pressure levels jumped from 111 mm Hg to 134 mm Hg. This led to an increase of 21% in blood pressure levels. 
 
The average page load times of the websites used in the study were between 8.8-10.5 seconds and participants used words such as ‘frustrating’ and ‘excruciating’ to describe the page load speeds. Participants felt anything above five seconds for a page load time is ‘inconvenient’ and ‘unacceptable’. 

In second place come multiple pop-ups. They caused participants’ blood pressures to rise from 108 mm Hg to 130 mm Hg. The pop-ups participants saw during the experiment included newsletter subscriptions, discount codes, sale awareness and trial offer pop-ups. Participants stated that the use of multiple pop-ups was ‘annoying’ and ‘unnecessary’. 

In third place on this list is 'auto-play music' as participants’ blood pressure elevated by an average of 20%, from 106 mm Hg to 127 mm Hg. Users thought the unwelcome blaring of auto-play music on the websites was ‘infuriating’ and ‘disruptive’.
 
In comparison, auto-play videos fared better in fifth place as participants’ blood pressure surged from 104 mm Hg to 121 mm Hg, a 16% increase. Even though users found auto-play videos ‘distracting’, they said it was easier for them to spot and turn off the source of the sound compared to auto-play music.
