This exercise habit is making your skin look older, according to experts

There are so many dilemmas when it comes to exercise: quantity versus quality, volume versus intensity, high impact vs low impact. But when we factor in ageing well and maintaining beautiful, radiant skin is added in as a factor, the choices suddenly become clearer.

If you want your skin to look great, don’t worry about clocking up more hours in the gym. There’s a way to efficiently do what’s necessary for your body – and it doesn’t involve excessive exercise, which can actually do more damage than good.

The next question, of course, is how? Join us in delving into this anti-ageing topic with three experts: a doctor, a personal trainer and longevity specialist. Here’s what they have to say…

How excessive workouts and stress cause cellular ageing

One of the biggest mistakes people make when it comes to working out is thinking that more activity always guarantees more benefits. However, poorly structured workouts with too much exercise or moves that are not well planned can lead to unnecessary wear and tear on your body (including your skin).

Moderate exercise boosts collagen and oxygen

This increases the risk of injury and results in chronic fatigue, which is counterproductive in the long term.

“The ideal approach is to create a structured, optimised exercise plan that stimulates key biological markers (or indicators) associated with living a long and healthy life – but without placing undue stress on the body,” explains longevity expert Gonzalo Ruíz Utrilla. “What truly makes a difference [with exercise] is the type of physical challenge the body receives and how it adapts to it.”

If we overdo exercise past a certain age, we combine the stress of sport with a high allostatic load. The allostatic load is the wear and tear the body experiences as it responds to demands – not just physical, such as exercise, but also life stress. When these loads become too heavy, they can over-activate your sympathetic nervous system.

“This excessive activation triggers chronic stress,” says the expert. “This stress not only impairs your body’s ability to repair itself but also decreases your metabolism’s flexibility, promotes continuous systemic inflammation and causes cells to age more quickly.”

The skin benefits: How moderate exercise boosts collagen and oxygen

How does working out affect blood circulation and tissue oxygenation, and what specific benefits does moderate exercise offer as far as skincare?

Dr Sofía Ruiz del Cueto, co-director of Madrid’s Mira+Cueto aesthetic clinic, states that, “When you boost blood circulation, the skin receives a greater supply of essential oxygen and vital nutrients.

“This process allows the skin to renew itself by forming necessary collagen and elastin, and repairing damaged cells while also boosting hydration. It’s also effective at speeding up the removal of waste and toxins, which stops the kind of inflammatory reactions that cause premature ageing.”

According to the doctor, “Exercise also modulates cortisol levels (a hormone related to stress), which helps prevent premature ageing.”

She advises moderate cardiovascular exercise around three to five days a week, accompanied by a sensible diet rich in protein and antioxidants, as well as adequate hydration.

Is too much exercise making your skin look older?

You may be wondering if there are certain types of exercise that should be avoided because of the potential negative impact on your skin’s appearance. “You should avoid overdoing your workouts, because too much exercise speeds up cell damage (oxidation) and increases inflammation in the body,” says the doctor.

The expert also has one big “Do” and a big “Don’t”:

Do stay hydrated before, during, and after exercise – it will keep your skin from being dehydrated, too.
Don’t exercise during peak UV exposure hours or in high temperatures.

Impact training vs. strength training: Which is better for longevity after 50?

You may have also heard the notion that impact training accelerates ageing. According to CrossFit expert and personal trainer Jesús Valor, it’s crucial to understand precisely what “impact training” means, especially after the age of 50.

“By impact training, we don’t mean those group classes where jumping is the main feature of the workout, but rather exercises that make the bones, tendons and joints truly feel that they’re being engaged,” the expert says. “This is best achieved through strength training, which is highly recommended over 50 because, particularly for women experiencing menopause and a subsequent drop in oestrogen, they need to focus on it more than ever.”

Muscle is an endocrine organ that sends internal messages. For this reason, he believes, impact workouts (adapted to individual needs) are beneficial in every sense. “There is no scientific evidence that impact training, in moderation, accelerates skin ageing,” says Valor.

He advises that as time progresses, the body’s adaptation to stimulus and recovery naturally slow down, so the quality of your workout is paramount during midlife.

Strength exercises are the most highly recommended for delaying ageing, including for your skin. We’re not talking about lifting huge amounts of weight, but about properly moving your body – it’s a win-win.

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Each time you go for a jog, ride your bike, or get active in other ways, you’re giving your brain a boost. A small new study has for the first time directly documented this phenomenon, which the researchers call “ripples” — brief bursts of electrical activity in a part of the brain called the hippocampus.

While exercise is known to improve memory, scientists have mostly studied this effect by using behavioral tests or brain imaging methods like MRIs, says Michelle Voss, PhD, one of the study’s authors, a professor, and the director of the Health, Brain, and Cognitive Lab at the University of Iowa in Iowa City.

But she says these approaches can’t precisely identify where “ripples” originate, particularly in the deep brain structures like the hippocampus, a part of the brain strongly connected to memory and learning, she says.

The current study, published in Brain Communications, recorded electrical activity directly, using surgically implanted (intracranial) electrodes. “This allowed us to observe how exercise changes the brain’s memory circuits in real time,” Dr. Voss says.

20-Minute Bursts of Exercise Increase Brain Ripples

To conduct the study, the researchers recruited 14 participants between ages 17 and 50 with drug-resistant epilepsy. The subjects had already been fitted with intracranial electrodes as part of their preparation for surgical epilepsy treatment.

The participants performed a 5-minute warm-up and then rode a stationary bike for 20 minutes at a pace they could maintain. Researchers recorded their brain activity before and after the biking session.

The electrodes showed an increased rate of so-called sharp-wave ripples from the hippocampus and connections with cortical regions of the brain, which are involved in learning and memory.

“Sharp-wave ripples have long been known from animal studies to play a central role in memory,” Voss says, adding that recent studies using intracranial recordings in humans also support the importance of ripples for human memory.

“Our findings are the first to show that exercise can modulate these ripple signals in the human brain,” she says.

Researchers also observed that larger increases in heart rate during exercise were associated with larger changes in ripple activity in cortical networks, Voss adds.

What’s Already Known About Exercise, Memory, and Learning

“We know that exercise is the number-one thing we can do to enhance our memory and learning,” says Catherine Franssen, PhD, an assistant professor in the School of Life Sciences and Sustainability at Virginia Commonwealth University in Richmond. “Exercise will enhance both our ability to learn new things and our ability to remember previously learned things.”

Movement helps pump oxygenated, nutrient-rich blood to the brain, says Dr. Franssen, who was not involved with the new study: “We’re able to activate those brain cells more effectively and energize them.”

The increased blood flow stimulates the growth of new neurons and enhances the production of brain-derived neurotrophic factor (BDNF), a molecule that strengthens connections between brain cells and supports learning, says the neurologist David Perlmutter, MD, who was not involved with the latest study.

Exercise helps build connections between neurons, which deepens and strengthens brain networks, Franssen says.

Physical activity also improves metabolism, which improves insulin sensitivity, helping blood sugar regulation and giving the brain a “more stable and reliable supply of fuel,” Dr. Perlmutter says.

“This is critically important because the brain is an energy-intensive organ, consuming roughly 20 percent of the body’s energy despite representing only a small fraction of body weight,” he adds.

The Research Has Limitations

Voss says researchers were careful to “exclude signals that contained epileptic activity. However, of course, we can’t statistically control for the accumulated effects of having epilepsy on the brain.”

The exercise-brain ripple patterns observed in the current study also closely match those observed in healthy adults using noninvasive brain imaging, such as MRI, she added.

“That convergence across very different methods is one of the strongest indicators that the effects are not specific to epilepsy, but reflect a more general human brain response to exercise,” Voss said.

Researchers also didn’t directly test memory performance, Voss notes. “While hippocampal ripples are strongly linked to memory processing in decades of neuroscience research, the next step will be to measure how exercise-related changes in ripples relate to memory performance in the same individuals.”

Future studies should also compare exercise with other everyday activities, such as sitting quietly or light movement, to determine how specific these effects are to aerobic exercise at the intensity that was studied, she says.

Satisfy Your Brain’s Exercise Craving

It’s never too early or too late to start exercising for brain health, Franssen says.

People of any age, from grade-school children to people in their nineties, can benefit from increased physical activity, Perlmutter says. “My recommendation is to consider taking advantage of the connection between physical activity and brain health across the entire range of human aging.”

Any type of exercise is great, Franssen says, but especially “repetitive behaviors,” like swimming, jogging, and walking.

“Sometimes we let the hugeness of putting in a huge fitness routine get in our way,” she says. “Having a little exercise snack every so often is also very important to improving cognition.”

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Increasing our level of physical fitness leads to a bigger release of brain-boosting proteins following one session of exercise, a new study led by a UCL researcher has found.

The study, published in Brain Research, took a group of inactive unfit participants through a 12-week training programme of cycling three times per week and made them fitter. Researchers found as their fitness increased, so did the amount of brain-derived neurotrophic factor (BDNF) released following exercise, resulting in improved brain function.

Just 15 minutes of moderate to vigorous aerobic exercise releases BDNF, a brain protein which is known to support the formation of new neurons and new synapses (connections between brain cells), and maintains the health of existing neurons. This is the first study to show that for unfit people, just 12 weeks of consistent training can boost the brain’s response to a single 15-minute workout.

The study, led by Dr Flaminia Ronca (UCL Surgery & Interventional Science, and the Institute of Sport, Exercise and Health), involved 30 participants – 23 male and seven female – taking part in the 12-week programme. To assess fitness levels throughout the programme, participants completed VO2max tests every six weeks, which measures the maximum rate of oxygen your body can consume and use during intense exercise.

BDNF levels were measured pre- and post-VO2max testing, alongside a series of cognitive and memory tests, while also measuring changes in brain activity in the prefrontal cortex – where executive functions such as decision-making, emotion regulation, attention and impulsivity are controlled.

By the final week of the trial, results showed that baseline levels of BDNF did not change, but participants did show a larger spike of BDNF following intense exercise, compared to how their brains responded to intense exercise before the 12-week programme. This was linked to improvements in VO2max (aerobic fitness).

Higher overall BDNF levels and stronger exercise-induced increases were also associated with changes in activity across key areas of the prefrontal cortex during attention and inhibition tasks, though not during memory tasks.

Overall, the results showed that increasing physical fitness can enhance the brain’s ability to produce BDNF in response to acute bouts of exercise, which can have a strong positive influence on neural activity.

Lead author Dr Flaminia Ronca said: “We’ve known for a while that exercise is good for our brain, but the mechanisms through which this occurs are still being disentangled. The most exciting finding from our study is that if we become fitter, our brains benefit even more from a single session of exercise, and this can change in only six weeks.”
