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.

Health and happiness go hand in hand

People who describe themselves as happy tend to have fewer health problems, a lower risk of depression, and longer lives. Research suggests that, on average, 50% of people’s general level of happiness is determined by genetics, with the rest dependent on the individual’s perception and specific circumstances. Some research suggests that people can adopt various strategies that can increase happiness, from forming stronger social bonds to investing in experiences to interacting more with outdoor green spaces.

What’s your daily budget for saturated fat?

To help prevent high LDL cholesterol, experts recommend limiting saturated fat to 7% of total daily calories. Changes such as avoiding red and processed meats, cheese, and other full-fat dairy products can help. People can look up the saturated fat content of foods with free apps such as Lose It! or MyFitnessPal. To replace lost calories, the best choices are unsaturated fats such as liquid vegetable oils from vegetables, nuts, and seeds, as well as avocados, nuts, and nut butters.
