Constant fatigue is one of the most common problems today. Do you often feel low on energy, struggle to sleep well, or feel like your vitality is missing? We usually blame stress, work, or diet. But there’s another important factor we almost always forget: light.

Both sunlight and the artificial light in our homes affect us much more than we think. More and more studies confirm it: the light our body receives plays a fundamental role in our health and in how we feel every day.

Did you know sunlight regulates much more than vitamin D?

Our body has an internal clock that controls when we feel hungry, sleepy, energized, or ready to recover. And this clock resets itself every day thanks to sunlight.

Morning light

When natural light enters our eyes in the morning, the brain gets the signal that a new day has started. This activates internal processes that lift our mood, boost our energy, and help us think more clearly.

Nighttime darkness

As it gets dark, the brain understands it’s time to rest and begins producing melatonin. This helps us relax and drift into deep sleep.

It’s a simple, natural system that has been working for millions of years—and one our body still depends on today.

Constant fatigue caused by artificial light

We’ve replaced the natural light of the sun, which has always guided our body’s rhythm, with hours and hours under artificial lights.

Think about it: most of the day we’re indoors—at the office, at home, at the gym—almost always under LEDs or fluorescents. On top of that, we spend endless hours in front of screens: phones, computers, TVs…

This artificial light doesn’t have the same quality as sunlight. It’s loaded with blue light and lacks the full natural spectrum. That’s why, when it’s 10 p.m. and you’re staring at your phone, your brain still thinks it’s midday. This suppresses melatonin production and makes it harder to fall into deep, restorative sleep.

On top of this, there are invisible signals all around us: Wi-Fi, Bluetooth, cell towers… an overload of stimuli that stress and confuse the body, which is designed to follow the clear, simple signals of nature.

Blue light from screens and its impact on sleep

The blue light emitted by phones, computers, and TVs tricks the brain into believing it’s still daytime. This suppresses melatonin—the sleep hormone—and makes deep rest harder to achieve. Over time, this nightly exposure to blue light can lead to constant fatigue and a persistent lack of energy during the day.

The Sun is not our enemy

For years we’ve been told that the sun is dangerous and that we should avoid it. It’s true that getting sunburned is harmful, but does it really make sense to think that the sun—the very source of life on Earth—has suddenly become our number one enemy?

The problem isn’t the sun—it’s that our bodies and skin are no longer used to it. We spend almost the entire year indoors, and then suddenly in the summer we want to spend hours under the blazing sun. No wonder our skin reacts!

In contrast, getting regular and moderate sun exposure is an important part of a healthy lifestyle. It helps us produce vitamin D, balance our mood, reduce inflammation, and provides many other benefits.

After spending time in the sun, your skin needs hydration. In this case, you can use Ringana’s natural aftersun, a soothing and moisturising cream that nourishes the skin and provides an antioxidant effect. Perfect for caring for your skin naturally, without toxins or artificial additives.

What can you do? 4 simple steps to recharge your batteries

It’s clear that living in close contact with nature would be ideal. But even if we live in an urban environment, there are simple actions that can help us reconnect with natural light and regain our energy.

1. Start your day with natural light. Before checking your phone or turning on screens, step outside or open the window and let the morning light hit your face and enter your eyes (without sunglasses!). Just 10–15 minutes is enough for your body to understand it’s time to get going. This morning exposure helps reset your internal clock and generate natural energy for the whole day.

2. Take your midday break outdoors. If you work in an office, use your lunch break to get outside. Even a 15-minute walk in the midday sun will recharge your batteries and offset the negative effects of spending so many hours under artificial light.

3. Protect yourself from artificial light in the evening and at night. As the sun begins to set, it’s time to help your body understand that the day is winding down.

• Night mode on screens: Turn on the blue light filter on your phone and computer. Most devices have a “Night Shift” or “Eye Comfort” setting.
• Blue light blocking glasses: If you spend many hours in front of screens in the evening, blue light blocking glasses can be a fantastic investment to help you sleep better.

4. Do a “clean-up” in your bedroom. Your bedroom should be a sanctuary for rest.

• Turn off Wi-Fi at night: It takes no effort and gives your body a break from artificial signals for 8 hours.
• Keep your phone away and on airplane mode: Leave your phone away from the bed and in airplane mode. Your alarm will still work, but you’ll avoid the temptation to check it and reduce exposure to radiation.

Everything starts with a small change. Step outside, breathe, and let your body reconnect with its natural rhythm. When your body receives the signals it needs, you can reduce constant fatigue, regain energy and mental clarity. And if you want to keep improving, here are 6 simple strategies to boost your memory, which will also help you keep your mind sharp and active.
