Rheumatoid arthritis (RA) affects two to three times as many women as men. Scientists are uncovering RA's potential genetic and hormonal underpinnings, which point to potential reasons why women are more vulnerable. The newest treatments, called Janus kinase (JAK) inhibitors, resulted from research that has teased out delicate differences in immune system pathways. They block numerous proteins that ramp up inflammation fundamental to RA. The wide array of drug options now available for RA help doctors personalize therapies to each patient.

Certain strategies can help people avoid flare-ups of diseases that seem to be affected by cold weather. For example, people with psoriasis can ward off dry skin (which causes flare-ups) by taking short, lukewarm showers, using a humidifier at home, and moisturizing with cream-based emollients. People with asthma should try to do outdoor activities during warmer parts of the day, take a puff of a rescue inhaler before going out, and wear a mask when outdoors. And people with arthritis can exercise and try heat therapy.
