No evidence suggests that nicotine patches promote weight loss. Nicotine suppresses appetite but also raises health risks such as high blood pressure and narrowed arteries. People can talk to a doctor about medically supervised weight loss.
Many spices inhibit damaging inflammation that can cause or worsen a variety of chronic diseases. Four beloved holiday spices—cinnamon, cloves, ginger, and turmeric—boast a variety of health benefits, but need to be used liberally to maximize the effects. People can challenge their palates to use more spices all year long by trying new recipes, testing spices in restaurant or ready-made meals, and bringing spice-laden dishes their ancestors once enjoyed to their own tables.
Researchers have found that high blood pressure, diabetes, and smoking had the greatest association with the likelihood of a dementia diagnosis as people age. Managing these issues could offer protection.
A variety of health conditions can be influenced by sleep position. Side sleeping helps people breathe easier, hampers heartburn, and is safer during pregnancy, but it may aggravate joint pain. Back sleeping keeps the spine straighter, but can intensify breathing problems, worsen heartburn, and cause other problems during pregnancy. People should talk to their doctor if they have a health condition that could be affected by the way they sleep, but otherwise can sleep in the position that is most comfortable for them.
X-rays can detect a broken bone, dislocation, or joint problem. People should seek an x-ray if an injury results in severe pain; severe or persistent swelling or bruising; difficulty moving or bearing weight; or a noticeable deformity.
Over-the-counter cold remedies can be helpful, but they must be carefully considered before use. They contain drugs that can cause serious side effects, interact with other medications, and worsen certain health conditions. For example, decongestants can help ease a stuffy nose but also can increase blood pressure and heart rate. And cough suppressants can help someone stop coughing, but taking too much can cause dizziness, confusion, or even changes in mood or thinking.
A 2025 study of 250 people found that the brain can tell the immune system to prepare for impending infection even before a microbe enters the body. Scientists asked volunteers to don virtual reality headsets that showed various virtual people approaching them. Some of those approaching appeared to be healthy and others appeared to be sick. Brain scans and blood tests showed that participants’ brains activated their immune systems when a virtual sick person simply came near them.
A 2025 study suggests that respiratory syncytial virus (RSV) can lead to heart-related complications, such as a heart attack, chronic heart failure, or an irregular heartbeat—even in people without a previous heart condition.
A 2025 study that included 97,000 people found that those who ate the most cruciferous vegetables—between 20 and 40 grams per day—had a 17% lower risk of developing colon cancer, compared with people who ate the least.
While a healthy eating plan is crucial for health, bending the rules on occasion probably won’t hurt most people. One strategy to try is the 90-10 rule—eating healthy foods 90% of the time and splurging on unhealthy foods 10% of the time. For example, if someone eats three meals a day for a week, for a total of 21 meals, the person would be able to splurge on 10% (about two) of the meals. Dietitians warn that applying the 90-10 rule to every meal can lead to trouble, such as weight gain.
