A 2023 study found that people who said they ate the most tomatoes (more than 110 grams per day, for three years) experienced a 36% reduction in hypertension, compared with people who said they ate the least tomatoes per day (less than 44 grams).

A 2023 study suggests that having diabetes may be tied to a higher risk of developing colorectal cancer than not having diabetes.

A 2023 study found that pet owners who lived alone had slower rates of cognitive decline compared with people who lived alone but had no pets. Living with a dog or cat may help ease loneliness — an important risk factor for cognitive decline.

It may take a combination of approaches to ease the discomfort of a sciatica flare-up. Strategies include staying active, modifying activities to make them less demanding on the back, stretching, using hot or cold therapy, meditating, and using oral or topical painkillers. If the flare-up lasts longer than a week or two and isn’t responding to home remedies, it’s time to make a doctor appointment. The doctor might order imaging tests and prescribe a prescription anti-inflammatory drug, such as oral or injected prednisone.

In most cases, bee, wasp, or hornet stings can be treated with simple remedies. For example, placing a cold pack on the sting site helps reduce swelling. Applying over-the-counter hydrocortisone cream helps relieve swelling and itching, too. Taking an antihistamine—such as fexofenadine (Allegra) or loratadine (Claritin)—also eases itching. If symptoms persist for a few days, it’s time to call a doctor. If a severe allergic response develops—indicated by difficulty breathing or hives—it’s crucial to call 911 for help and get an injection of epinephrine as soon as possible.

Tinnitus is widely believed to be caused by hearing loss. But that theory hasn’t explained the cause of the problem for people with normal hearing tests who still have tinnitus. Increasing evidence suggests that some of these people have “hidden” hearing loss: damage to the auditory nerve—which carries sound signals from the ear to the brain—that isn’t picked up by conventional tests. The evidence offers hope that if perhaps one day auditory nerve fibers can be regenerated, it might help reduce the perception of tinnitus.

It’s dangerous to keep unneeded or expired medications around the house. But it’s bad for the environment to simply flush or throw away the drugs. It’s best to dispose of them by bringing them to a drug take-back site (such as a drugstore or law enforcement office) or a medical waste collection site (such as the local landfill). As a last resort, it’s okay to toss medications into the trash with careful preparation. The FDA recommends mixing medicines with unappealing substances, such as cat litter or used coffee grounds; placing the mixture in a sealable plastic bag or container; and throwing the bag or container in the trash.
