LACK OF SLEEP

LACK OF SLEEP

One week of bad sleep can “switch off” hundreds of genes and raise the risk of a host of illnesses including obesity and heart disease, scientists claim.

Latest research from the University of Surrey has found that as little as one week of inadequate sleep is enough to alter the activity of hundreds of human genes.

Latest research from the University of Surrey has found that as little as one week of inadequate sleep is enough to alter the activity of hundreds of human genes. The research monitored the activity of all genes of the human genome and found that inadequate sleep (less than 6 hours a night) affects the activity of over 700 of our genes. These included genes which are linked to controlling inflammation, immunity, and the response to stress.

Furthermore, the research shows that inadequate sleep reduced the number of genes that normally peak and wane in expression throughout the 24-hour day from 1,855 to 1,481. The authors found that the number of genes affected by sleep deprivation was seven times higher after a week of insufficient sleep.

Sleep deficiency leads to a host of significant health conditions including obesity, heart disease, and cognitive impairment, but until now scientists were unclear how gene expression patterns were altered by insufficient sleep. These ‘gene expression’ patterns provide important clues on the potential molecular mechanisms linking sleep and overall health.

Derk-Jan Dijk, Director of the Sleep Research Centre at the University of Surrey says:

“This research has helped us to understand the effects of insufficient sleep on gene expression. Now that we have identified these effects we can use this information to further investigate the links between gene expression and overall health.”

The research was conducted by an interdisciplinary team of researchers consisting of physiologists, sleep and circadian rhythm experts and experts in functional genomics and bioinformatics.

Colin Smith, Professor of functional genomics at the University of Surrey says: “The current interest in sleep and circadian rhythms as determinants of health and disease is a vital area of research. By combining our expertise in sleep and ‘genomics’ (the study of the full complement of our genes), we are starting to make breakthroughs that will have an impact on our understanding and treatment of poor health arising from insufficient sleep.”

solan teen kills leopard

Solan—In a shocking incident on Monday, an 18-year-old youth, Pravesh, survived a vicious leopard attack in Sarli village of Arki subdivision. The teenager reportedly fought the leopard for nearly 12 minutes before breaking its jaw, killing the animal on the spot.

Quick Thinking Saved His Life

Pravesh told the media that he was walking from the fields to a nearby shop in the morning to fetch milk when the leopard, hidden in the crops, lunged at him. Noticing the leopard’s tail, he attempted to run but fell after a short distance. During the attack, he covered his neck with his hands to protect himself from fatal bites.

The teenager continued to struggle with the leopard, repeatedly attempting to put distance between himself and the predator. In a desperate move, he grabbed the leopard by its mouth, twisted its jaw, and broke it, killing the animal instantly. Pravesh sustained multiple injuries, including deep claw marks, and is currently receiving treatment at Arki Hospital. Police and forest department teams have launched an investigation into the incident.

Serious Allegations of HP Forest Department’s Negligence

One of Pravesh’s relatives accused the forest department of negligence, noting that similar attacks had occurred in the area previously.

Earlier, a leopard had attempted to attack a scooter rider, who managed to escape. The family said they had informed the forest department on March 6 about potential danger, but no concrete action was taken. Villagers waited for three hours for a forest team to arrive, but none came. When the Block Officer eventually visited, he reportedly told villagers to ensure their own safety. Requests for cages to capture the leopard were also denied, with officials asking for written complaints instead.

Himachal weather forecast August

SHIMLA | 7 August 2025 –The India Meteorological Department (IMD) has forecast light to moderate rainfall across Himachal Pradesh over the next two weeks, with isolated heavy to very heavy showers likely over the low hills, plains, and adjoining mid-hill regions. While the ongoing monsoon remains vital for agriculture, it also brings an elevated risk of localized flooding and landslides.

Week of August 8–14

Maximum temperatures will range from 22°C to 34°C, depending on elevation—22°C to 28°C in high hills, 26°C to 30°C in mid-hills, and up to 34°C in lower regions. Minimum temperatures are expected to remain near normal, between 12°C and 24°C. Cooler conditions may persist in districts like Kullu and Lahaul-Spiti.

Week of August 15–21

Similar rainfall patterns are expected to continue, with scattered heavy rain episodes. Temperature trends will remain stable, though slightly below-normal maximum temperatures are likely in parts of Lahaul-Spiti, Mandi, Kangra, and Kullu districts.

Outlook for Late August

Rainfall is expected to remain broadly normal, with region-specific variations. Districts such as Kinnaur, Shimla, and Sirmaur may see below-normal precipitation, while Una, Kangra, Hamirpur, Bilaspur, and Solan are likely to receive above-average rainfall. Both maximum and minimum temperatures are forecast to stay close to seasonal norms.

Officials at the Meteorological Centre in Shimla have urged residents and local authorities to remain alert for sudden heavy downpours, which could disrupt road connectivity and trigger landslides—especially along vulnerable hillside routes. Past monsoon episodes have blocked key highways, including routes between Mandi and Kullu and near Banjar, underscoring the ongoing challenges in the region.

This advisory comes as Himachal Pradesh continues to face the dual pressures of sustaining its agriculture-dependent economy while managing the life and infrastructure risks posed by an active monsoon. Continued vigilance and preparedness remain crucial.
