Intrusive thoughts are unwanted thoughts or mental images that make people feel uncomfortable. They're common, affecting some six million Americans and can be effectively managed using tools such as cognitive behavioral therapy. They can be associated with mental health disorders such as obsessive-compulsive disorder or post-traumatic stress disorder, but many people who experience them don't meet the criteria for a mental health disorder. The thoughts may be triggered by stress or anxiety.

It's impossible to never worry about your health - but are you worrying about the right things? Popular fears and Google and TikTok searches suggest our top concerns may bypass common health issues. So what should concern us and what can we do about it?

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

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.

A 2023 study suggests excessive TV-watching, defined as four or more hours a day, is associated with higher risk of developing brain-based disorders such as dementia, depression, and Parkinson's disease.

Forgiveness is defined by replacing ill will toward an offender with goodwill. A 2023 study suggests forgiveness boosts mental health by reducing depression and anxiety levels. Other evidence suggests physical benefits as well. Studies indicate forgiveness also eases stress, improves sleep, and lowers blood pressure and heart rate. Being unable to forgive can raise blood pressure, which can affect overall heart health. Some people are innately better at forgiving, but Harvard experts say all people can learn skills that help them forgive.

Cold symptoms can worsen at night for several reasons. Immune cells become more active at night, creating inflammation that aggravates respiratory symptoms. Lower cortisol levels also fuel symptoms, and lying down allows mucus to pool at the back of the throat.
