Circadian rhythm refers to the changes that occur in organisms over a 24-hour period. Rest and activity patterns throughout the day are one way to explore components of circadian rhythm. One study found that more fragmented and weaker circadian rest activity rhythms and having peak activity time later in the day were linked to an increased risk for dementia.
Evidence shows that weight management outcomes are shaped not only by diet and exercise but also by timing, adherence, and clinical support. Initiating structured interventions early in the year aligns behavioral momentum with metabolic and medical strategies to improve long-term weight loss and disease risk reduction.
Breathing is the most fundamental rhythm of life. But have you ever thought that within each inhale and exhale lies an important code for measuring physical health — lung capacity? Now, there's no need for complex instruments. Just open the Treelet Health APP and use your phone's microphone to complete a lung capacity test, easily keeping track of your respiratory vitality. Today, we will comprehensively interpret the mysteries of lung capacity and how to make good use of this new function to protect respiratory health.
Medical News Today has recently covered several pieces of research that support a strong link between sleep and dementia risk. One of these studies, using MRI scans, found that people with a weaker glymphatic system—which clears toxins from the brain during sleep—have a higher risk of dementia. Another study found that moderate to severe obstructive sleep apnea may raise the risk of tiny brain bleeds, which could increase the chances of dementia and stroke. And another study suggested that people with chronic insomnia may be at a greater risk of developing dementia or mild cognitive impairment, which has been linked to faster brain aging.
Vitamin B12 is a critical component of the diet and can be found in animal food sources. Vitamin B12 and its available forms have been the subject of ongoing research. A recent comprehensive review discusses key aspects of vitamin B12 and components of natural versus synthetic forms of the vitamin.
In 2013, Alcohol Change UK started the “Dry January” campaign, where people could commit to abstaining from drinking alcohol for the entire month. In January 2025, about 200,000 people worldwide signed up to participate in Dry January. A new study reports that abstaining from alcohol for just one month can offer meaningful physical and psychological improvements.
With progress in diagnosis and treatment, more people are surviving cancer than ever before. However, long-term health issues after cancer treatment may affect a person’s longevity. Research has now found that cancer survivors who follow a heart-healthy lifestyle can improve their chances of living longer. The study suggests that seven behaviors, including being physically active, eating a balanced diet, and quitting smoking, not only reduce a person’s overall mortality risk by 38%, but are also associated with reduced cancer mortality.
Past research shows that engaging in creative activities can help keep your brain healthy as you age. A new study has found that not only can creative pursuits help with brain health, they may also help delay brain aging. Researchers discovered that those with long-term involvement in creative activities have a more ‘youthful’ brain age on average.
Skin health is affected by multiple factors but one area of interest is how gut health relates to skin health. A scoping review discussed the available research on how probiotics, prebiotics, and synbiotics impact the skin. The review identified the substantial research conducted in this area and provided suggestions for future research.
Recent studies have highlighted the potential health benefits of coffee, particularly its influence on longevity and reducing chronic disease risk. A study suggests that consuming 3 to 4 cups of coffee daily could increase lifespan and may add 5 extra years of life. A recent review also indicates that 3 to 5 cups of coffee a day could decrease mortality and lower the risk of some diseases. A third piece of research further suggests the health benefits of drinking coffee, especially in women as they get older.

A new study from researchers at the University of Florida examined brain aging in a group of middle-aged and older adults, many of whom had chronic pain. ‘Brain age’ refers to how old the brain appears on MRI scans, which the scientists compared to the participants’ actual age. The researchers learned that people who had healthier lifestyle behaviors were more likely to have a younger brain age, which was true even in people with chronic pain.
