Traya Report: South India Is the Country's Sleep Deprivation Capital, Chennai and Coimbatore Top the Charts

If India's sleeplessness had a capital region, it would be the South. That is the unambiguous finding of the Traya Hair Test Report, an analysis of 4,89,721 hair test responses from men across 20 states and 50 cities. Every one of the five cities where men report the worst sleep is southern: Chennai at 30.9% disturbed sleep, Coimbatore at 30.4%, Vijayawada at 29.8%, Visakhapatnam at 29.3% and Hyderabad at 27.6%. 

The national average for disturbed sleep is 22.1%. The southern cluster does not merely exceed it; it occupies an entirely different band. In Chennai, adding the 11.6% of men who report slight problems during sleep to those reporting disturbed sleep means that more than four men in ten are not sleeping properly. In no northern city does the combined figure come close. 

Tamil Nadu Leads Both Traya Report Tables 

The state rankings confirm that this is not a city level quirk. Tamil Nadu leads India in disturbed sleep at 30.4%, followed by Andhra Pradesh at 29.8% and Telangana at 27.6%. And the pattern is not confined to sleep. Tamil Nadu also tops the country's stress table, with 10.2% of its men reporting high stress, while the city stress rankings are led by Vijayawada at 10.6%, Salem at 10.5%, Coimbatore at 10.4% and Chennai at 9.9%, four southern cities in the national top five. 

Within Tamil Nadu, the report's coverage is deep: 12,800 respondents in Chennai, 3,775 in Coimbatore and 1,837 in Salem, giving the state one of the most thoroughly measured samples in the dataset. Whatever is driving the numbers, it is not a small sample artefact. 

The Contrast With the Rest of India 

Set the southern figures against the country's best sleepers and the gap is stark. In Jodhpur, only 17.4% of men report disturbed sleep; in Patna, Jaipur and Varanasi the figure sits at roughly 17.8%. Rajasthan and Bihar, at 17.6% each, report the soundest sleep among all states. A man in Chennai is nearly twice as likely to be sleeping badly as a man in Jodhpur. 

The report does not diagnose causes, and the candidates are many: the density and pace of the southern urban economy, the region's concentration of IT and manufacturing work with its long hours and night shifts, commute times, screen habits, or simply a greater willingness among southern respondents to report a problem at all. Establishing which of these matters, and how much, is work for researchers. 

What the data does establish, at a scale that is hard to argue with, is the pattern itself. The South is India's economic showcase, its technology corridor and its manufacturing floor. On this evidence, it is also the part of the country where men's rest is being spent fastest, and the region with the most riding on the question of how to get it back.
