What are the Health Benefits of Sunshine?
For decades, many doctors have said that less is more when it comes to sun exposure. Ultraviolet light from the sun can age the skin and cause skin cancer, and people can get vitamin D from food or supplements instead.
But in recent years, some scientists have questioned this thinking after research suggested that moderate sun exposure may, at least in certain contexts, have some benefits. And that vitamin D supplements may not always be a good substitute.
'The 'never go outside without S.P.F. 50' approach treated sun exposure as if it were universally harmful,' said Dr. Lucy McBride, an internal medicine physician in Washington, D.C. But 'moderate, thoughtful sun exposure,' in accordance with your risk factors, she added, 'may offer benefits we're still discovering.'
Sunshine has a bright side.
It's undeniable that the sun's rays can damage your skin in ways that result in premature skin aging and cancer, said Dr. Elizabeth Ko, an internal medicine physician at UCLA Health who has written about the health effects of sun exposure.
But researchers have also identified a handful of potential, if limited, associations between sun exposure and health benefits.

Moon phase today: What the moon will look like on July 7, 2025
Ever wonder why the moon looks different every night? Well, that's because of a thing called the lunar cycle. This is a recurring series of eight unique phases of the moon's visibility. The whole cycle takes about 29.5 days (according to NASA), and these different phases happen as the Sun lights up different parts of the moon whilst it orbits Earth. The moon is always there, but what we see on Earth changes depending on how much it is lit up. See what's happening with the moon tonight, July 6. What is today's moon phase? As of Monday, July 7, the moon phase is Waxing Gibbous. From Earth, 89% of the moon will appear visible (according to NASA's Daily Moon Observation). This is the 12th day of the lunar cycle, and the moon is so close to being full. Some of the most notable things to spot with your bare eye tonight are the Aristarchus Plateau, the Mare Serenitatis, and the Mare Tranquillitatis. With binoculars, you'll also be able to catch a glimpse of the Posidonius Crater, the Alphonsus Crater, and the Clavius Crater. Add a telescope and you'll also spot Apollo 17, Fra Mauro Highlands, and Caucasus Mountains. When is the next full moon? This month's full moon will take place on July 10. The last full moon was on June 11. What are moon phases? Moon phases are caused by the 29.5-day cycle of the moon's orbit, which changes the angles between the Sun, Moon, and Earth. Moon phases are how the moon looks from Earth as it goes around us. We always see the same side of the moon, but how much of it is lit up by the Sun changes depending on where it is in its orbit. This is how we get full moons, half moons, and moons that appear completely invisible. There are eight main moon phases, and they follow a repeating cycle: New Moon - The moon is between Earth and the sun, so the side we see is dark (in other words, it's invisible to the eye). Waxing Crescent - A small sliver of light appears on the right side (Northern Hemisphere). First Quarter - Half of the moon is lit on the right side. It looks like a half-moon. Waxing Gibbous - More than half is lit up, but it's not quite full yet. Full Moon - The whole face of the moon is illuminated and fully visible. Waning Gibbous - The moon starts losing light on the right side. Last Quarter (or Third Quarter) - Another half-moon, but now the left side is lit. Waning Crescent - A thin sliver of light remains on the left side before going dark again.

The One Thing You Should Never, Ever Do in the Hour After Eating Lunch, According to a Cardiologist
The One Thing You Should Never, Ever Do in the Hour After Eating Lunch, According to a Cardiologist originally appeared on Parade. No matter what your health goals are, you likely start each day with the best of intentions. You have a healthy breakfast, full of fiber and protein. You enjoy a cup of coffee, which is known to support both brain and heart health. Maybe you even go for a walk or get a workout in. But by the time afternoon hits, it's easy for healthy habits to fall by the wayside. There's too much to do and not enough time, which can lead to doing (and eating) what's most convenient, even if it isn't healthy. And there's one common afternoon habit, in particular, that a cardiologist wishes people wouldn't do because it's detrimental to heart health. 🩺SIGN UP for tips to stay healthy & fit with the top moves, clean eats, health trends & more delivered right to your inbox twice a week💊 You're likely familiar with the afternoon slump. Typically, it happens about an hour after eating lunch. Blood sugar drops and tiredness sets in, making it hard to get through the rest of the day. To overcome it, many people turn to an energy drink. But Dr. Bhavna Suri, MD, a cardiologist with Manhattan Cardiology and contributor to LabFinder, wishes this habit would be left Suri explains that energy drinks can negatively impact heart health. 'Drinking these substances in excess sometimes speeds up our heart rate too much, or can cause some extra heartbeats, called ectopy,' she says, explaining that when this happens, it can lead to palpitations or a feeling of fluttering in the I'm a Cardiologist, and This 'Relaxing' Habit Is Actually Harming Your Heart Health Scientific research backs this up, showing that too much caffeine puts stress on the cardiovascular system, increasing the risk of arrhythmia. Other studies show that drinking energy drinks can cause blood pressure to go up. Drinking soda isn't any better. Scientific research shows that regularly drinking soda increases the risk of cardiovascular disease. Unfortunately, the same is true of diet soda. Another reason why Dr. Suri warns against using energy drinks to overcome an afternoon slump is because they can get in the way of getting a good night's sleep. Scientific research shows that not getting enough sleep on a regular basis increases the risk of cardiovascular disease. Related: Okay, so energy drinks and soda are out. What is a more heart-healthy way to get through the afternoon? Dr. Suri recommends taking a walk after lunch and getting some sunshine to help wake the body up. 'Incorporating a 15-minute walk [into your afternoon] can get blood circulating and can be good for your blood pressure and energy levels,' she says. Instead of downing an energy drink that can lead to heart palpitations, you'll be doing something that a wealth of scientific research has shown reduces the risk of cardiovascular Dr. Suri says that there's a way to craft your lunch in a way that will make experiencing an afternoon slump less likely. 'Having a protein-rich meal as opposed to high carbohydrates at lunch can improve energy levels,' she says. This is because simple carbs (like bread, chips, soda and pastries) increase blood sugar levels and then cause them to drop, which leads to a decrease in energy levels. But protein-based foods like chicken, tofu, beans and chickpeas don't spike blood sugar, which will keep energy levels more steady. Building an after-lunch walk into your daily routine is a way to keep your healthy habits going throughout the afternoon. By making a conscious effort to support your health in the morning and afternoon, you'll be more likely to keep it up in the evening too. Soon, your afternoon walk will become such an integral part of your routine that it will become automatic. And that's bound to benefit your heart both now and in the future.
