How much sleep keeps cognitive decline at bay?

Sleeping six hours or less is associated with impaired cognition, mostly in memory, as well as an increase in the protein that can form brain plaque. Sleeping nine hours or more is also linked to cognitive problems, especially in decision making.

Exposure to traffic noise linked to higher dementia risk

A decade or more of high exposure to traffic noise may increase dementia risk.

Healthy sleep patterns linked to lower risk of heart rhythm problems

People with healthy sleep habits may be less likely to have atrial fibrillation and bradyarrhythmia. Healthy sleep patterns include sleeping seven to eight hours a night and rarely or never having insomnia or daytime drowsiness.

Gifts that promote relaxation and resilience

An array of products that encourage people to relax can be good holiday gifts for friends and loved ones who need to reduce their stress levels. Suggestions include a year’s subscription to a meditation app; yoga props such as a mat, blocks, and straps; devices that enable self-massage of the upper body; and products that may foster sound sleep, such as a weighted blanket, a noise machine, and scented bath salts.

Do weighted blankets help with insomnia?

Insomnia affects approximately 10% of adults in the United States, and it is common with mental illness. Insomnia is unlikely to get better on its own if not actively treated. Many people are interested in treatment options that do not involve prescription medications, and a study from Sweden investigated the effectiveness of a weighted blanket on insomnia symptoms for people with insomnia and mental health problems.

Going to sleep late at night associated with obesity, big bellies

An international study published online June 1, 2021, by JAMA Network Open found that middle-aged and older adults had an increased risk of being obese or having a big belly if they went to sleep late, compared with a bedtime between 8 p.m. and 10 p.m.

Can blue light-blocking glasses improve your sleep?

Exposure to blue light during the daytime is desirable: it helps synchronize the body's circadian clock and helps people stay alert. But stimulation from certain wavelengths of blue light in the hours leading up to bedtime can interfere with sleep. Glasses that block stimulating blue light, whether prescription or not, are being touted as helping with sleep, but the evidence is questionable.

Cancer survivors' sleep is affected long after treatment

According to a new study, many people who have survived cancer treatment experience poor sleep long after treatment has ended. These people also reported emotional distress, financial hardship, and concern that their cancer might return. Many sleep disorders can be treated successfully, but an accurate diagnosis is essential to choosing the correct treatment.

What are the best ways to trim my waist?

Attacking visceral fat found deep inside the abdomen, around the organs, is the best way to reduce waist size. Doing more aerobic and resistance exercise, limiting sugary foods and beverages, getting enough sleep, and managing stress can help.

Embrace healthy habits for a robust memory

Healthy lifestyle habits may contribute to better brain health and sharper thinking skills. For example, getting at least seven hours of sleep each night gives the brain time to consolidate and store information and also flush out waste—including Alzheimer’s disease–related toxins. Eating a healthy diet helps ward off "mini" strokes that kill brain cells and lead to cognitive decline. Other healthy lifestyle habits that may help cognition include exercising, managing stress, and practicing mindfulness.
