From: The sleep loss insult of Spring Daylight Savings in the US is observable in Twitter activity
Normalized Twitter activity between 12 p.m. Sunday and 12 p.m. Monday prior to and following the 2012 Spring Forward event for each state. Red indicates an aggregation of data from the specified period over 4 weeks before the Spring Forward Event. Blue indicates data from the single 24 h period after Spring Forward has occurred. Dots are indicative of ‘raw’ data, while the corresponding curves demonstrate Gaussian smoothing. Texas exhibits the largest change following Spring Forward. Curves for nearly all states have aligned by Monday morning. The BSF peaks are slightly higher than the SF peaks in some states, largely due to televised events Before Spring Forward such as the Oscars. The Sunday of Spring Forward does not have a regularly scheduled popular television event, and as a result the SF curves have lower amplitude
