It's now understood that many factors influence a person's ability to lose weight —not just burning more calories than are taken in. A new study supports the idea that people using sleep hygiene tips to get sufficient sleep consume fewer calories than people who are sleep-deprived.

Sleep supplements, such as cannabidiol (CBD), melatonin, valerian, and chamomile promise a better night's sleep. But there is little evidence showing that they are effective. In addition, supplements aren't regulated, so it's not always clear if a formula contains what's listed on the label. Experts say that behavioral strategies are a better way to improve sleep. These include getting more exercise, going to bed and waking up at the same time each day, and sleeping in a cool, dark room.

A 2021 study verified that intermittent fasting may be an effective weight-loss strategy. It also seemed to improve some measures of risk for cardiovascular disease, such as lowering blood pressure, cholesterol, and blood sugar.

In 2022, Americans are projected to spend $35.6 billion on dietary supplements, even though there is little, if any, evidence of benefits. Loopholes in guidelines and clever marketing allow companies to promote these products with misleading promises.

Many habits can contribute to poor brain health, but four areas can have the most influence. They are the four S's: sitting, socializing, sleep, and stress.

Adopting simple lifestyle changes may help.

An observational study published in the February 2022 issue of Preventive Medicine suggests that laughing with friends is associated with a 30% reduced risk of developing functional disability—problems performing essential everyday activities.

A small, randomized trial published online Jan. 3, 2022, by JAMA Network Open suggests that aquatic or pool therapy is more effective at reducing chronic low back pain than physical therapy.

According to the CDC, about 42% of men ages 60 and older are obese. But fat in itself is not the issue, as the body needs a certain amount of fat to stay healthy. The amount of stored fat, and especially its location in the body, have the greatest impact on health. Consuming too many calories and not getting enough exercise both contribute to stored fat, but people can reduce their amounts by watching calorie intake and increasing exercise, in particular with resistance training for men.
