Some light-based treatments might help calm down angry, inflamed skin by copying how sunlight naturally balances certain chemicals in your skin, which could make conditions like eczema or psoriasis...
In people with certain skin conditions like psoriasis and eczema, their bodies make too much of two harmful chemicals that combine to create a damaging substance, which throws off their natural...
When your skin is exposed to sunlight, it releases a natural substance called nitric oxide that helps calm down harmful molecules in your skin and keeps things balanced — but this doesn't work right...
When there's less sunlight in winter or far from the equator, your skin makes less nitric oxide from sunlight, which can upset the balance in your skin and make conditions like psoriasis or eczema...
When mice with hardened arteries and ongoing stress get regular exercise, their artery plaques become smaller and more stable, thanks to a specific biological switch being turned off.
In mice, a protein called Kif4 helps move another protein, TARM1, to the surface of certain immune cells, making them stick more to blood vessel walls and causing more inflammation.
In mice, a natural brain protein called BDNF helps calm down immune cells that cause inflammation by blocking a specific chemical signal, which in turn reduces the release of harmful inflammatory...
When mice under long-term stress and with clogged arteries get to run on a wheel, their body produces a protein that calms down harmful immune cells, which helps reduce artery inflammation and keeps...
If you have heart disease and feel really stressed, working out regularly might help your body produce more of a brain-friendly chemical and reduce harmful inflammation in your blood.
When healthy young men don't get enough sleep for a few nights, their stress hormone (cortisol) actually goes down—but their blood sugar control gets worse. This suggests that something other than...
If you don't get enough sleep for a few nights, your body might start having trouble managing blood sugar, causing insulin levels to rise. But if you stay up all night instead, it doesn't have the...
If you don't get enough sleep for a few nights in a row, your body becomes less efficient at using sugar for energy—but if you stay up all night just once, it doesn't have the same effect. Missing...

Most of what people eat in Western countries today comes from plant-based foods like white bread, sugar, and vegetable oils — so much so that it’s like eating like a super-vegan, even if they’re not...
People with low levels of vitamin B12 in their blood may have more damage in their brain, like the insulation around nerve fibers breaking down and the brain shrinking over time.
Doctors use average blood test numbers to decide what's 'normal,' but those averages include sick people, so healthy people might be told they're unhealthy—and real health problems might be missed.
Working out your body helps it make more of certain natural chemicals that help repair muscles, create more energy factories in your cells, and slow down the wear and tear that comes with getting...
Not getting enough sleep for a long time—less than 6 hours a night—may greatly raise your chances of getting Alzheimer’s disease. And if you go without enough sleep for a week (less than 5 hours a...
When your skin is exposed to sunlight, it releases a substance that helps relax your blood vessels, which can lower your blood pressure.
Getting sunlight may help your brain grow new cells and repair itself by boosting a special protein called BDNF.
Eating harmful substances or not getting enough essential nutrients can mess up your body’s ability to fix itself, make enzymes work right, and stay balanced.
What you eat directly affects how well your body uses energy and how likely you are to get sick, because food gives your body the raw materials it needs to function.
The more medications people take, the worse their overall health seems to get.
