Rising temperatures cost Kerala residents 88 hours of sleep a year

Have you found yourself tossing and turning at night, unable to sleep despite the monsoon season in Kerala? If you live in the state, you are not alone. Rising temperatures and humidity, driven by global warming, are beginning to disrupt people's sleep cycles across the state. A new report by climate research organisation 'Climate Trends' reveals that the average resident in Kerala is now losing up to 88 hours of sleep every year due to rising temperatures compared to the 1970 baseline.

Sleepless nights in tropical paradise
The study, which analysed data from 1,338 cities worldwide, including 107 in India, highlights a concerning trend: sleep deprivation is rapidly emerging as a significant environmental health issue. The findings suggest that warm nights have more than doubled since 1970. Even during months like Karkidakam, traditionally known for cool monsoon rains, residents are increasingly complaining of stifling night-time heat.

How Kerala cities compare
While Chennai tops the list of sleep-deprived Indian cities, with residents losing an average of 93 hours of sleep annually, major urban areas in Kerala are close behind. People in Kozhikode, Kochi, and Kannur lose about 89 hours of sleep per year, while those in Thiruvananthapuram lose about 86 hours. This marks a sharp decline in sleep quality, directly linked to the region's changing climate.

National urban trends
The impact is being felt across metropolitan India. The study reveals that residents in Mumbai lose 84 hours of sleep annually, followed by Kolkata at 80 hours, Ahmedabad at 78 hours, and Hyderabad at 75 hours. Interestingly, cooler, inland cities fare slightly better but still experience significant sleep loss, with Bengaluru residents losing 67 hours, Delhi 66 hours, and Pune 65 hours. As global temperatures continue to rise, experts warn that sleep deprivation could trigger broader public health challenges, ranging from cardiovascular issues to diminished mental well-being.

How to improve sleep quality?
Here are a few expert tips to improve our sleep quality while living in places with hot weather.
a) Block direct sunlight from entering your bedroom. Even during the day, keep your blinds or curtains closed
b) Use light, cotton sheets. Pillowcases and socks kept in sealed plastic bags in the refrigerator for a few minutes before bed can also keep you cool.
c) Avoid foods that increase body temperature and eat what's easy to digest.
d) Wear soft, cotton clothing that is breathable.
e) Avoid having drinks like tea late during the day.
