Cooler Nights and Brighter Days Boost Sleep in Dementia Patients

A large-scale study shows that indoor environmental changes—such as cooler bedroom temperatures at night and brighter indoor light during the day—can significantly improve sleep in people living with dementia. Researchers analyzed over 26,000 days of data using contactless sensors placed in participants’ homes.

Extreme Heat Makes People More Negative

A large-scale global study shows that extreme heat affects not just our bodies, but also our emotions. Researchers analyzed over a billion social media posts and found that when temperatures exceeded 95°F (35°C), expressed sentiments became more negative, particularly in lower-income countries where effects were three times stronger.

How Cool Touch Travels From Skin to Brain

A groundbreaking study has mapped the full neural circuit that carries cool temperature signals from the skin to the brain. The pathway begins with molecular sensors in the skin, which activate neurons that send signals to the spinal cord, where the message is amplified before reaching the brain.

Heat Waves Reduce Politicians’ Speech Complexity

High temperatures lead to simpler language in parliamentary speeches. Analyzing seven million speeches from 28,000 politicians, researchers discovered that heat negatively impacts cognitive abilities. This effect was more pronounced in older politicians. The findings highlight the broader impacts of climate change on human performance and decision-making.

How the Brain Perceives Cooling Sensation

A new study delves into how our brains perceive temperature, particularly through the cooling sensation experienced when eating something like a chilled mint cookie. The study focuses on TRPM8 receptors in the mouth, which are activated by cold temperatures and menthol, explaining why mint tastes more intense when cold.
