Spring fever: why the spring sun is good for your body and mind

Lentekriebels: waarom de lentezon goed is voor je lichaam én geest

🌱 Spring has sprung!

Astronomical spring has begun and the clocks have gone forward again: that means longer days, more sun and… spring fever! But did you know that the sun's rays not only ensure a good mood, but also have a significant influence on your physical and mental health?

☀️ Sunlight and your psyche: how it works

Sunlight has a proven positive effect on our mental health. On sunny days, our serotonin levels are higher than on dark days. But what exactly does serotonin do?

😊 What is Serotonin (and Why Do You Want More of It)?

Serotonin is known as the 'happiness hormone'. It is a neurotransmitter: a substance that transmits signals in your brain and influences your mood, sleep, appetite and even your pain threshold.


If you have a serotonin deficiency, you may experience symptoms such as:

  • Depression

  • Insomnia

  • Fatigue

  • Bowel problems

  • Low pain threshold

🧠 Your gut: the second brain

As much as 90-95% of serotonin is produced in your intestines. Your intestinal flora therefore plays an essential role in your mental well-being. If your intestinal flora is out of balance, serotonin production can also be disrupted.
You can support healthy intestinal flora with:

  • A good probiotic

  • Fiber-rich diet

  • Magnesium and B12 (necessary for conversion to melatonin)

An orthomolecular nutritional advisor or therapist can help you balance your intestines and serotonin levels.

😴 From serotonin to melatonin: better sleep thanks to sun and nutrition

Serotonin is also the precursor to melatonin – your natural sleep hormone. With the help of co-factors such as magnesium and B12, serotonin is converted to melatonin. So: the better your serotonin production, the better you sleep.

🌞 The spring sun as a natural booster

In spring and summer we naturally produce more serotonin, simply because there is more sunlight. That is why you often feel happier and more energetic in these seasons.
A daily dose of sunlight of 15 to 30 minutes can make a difference. Make sure you:

  • Roll up your sleeves

  • Take off your sunglasses

  • Exposing your skin to the sun

This also stimulates the production of vitamin D , which is essential for your resistance, mood and bone health.

💡 Tip: how to make the most of spring

  • Get outside every day, preferably in the morning sun

  • Eat a varied diet with sufficient fiber, B12 and magnesium

  • Consider probiotics for intestinal complaints

  • Are you sleeping badly or feeling depressed? Get guidance from an orthomolecular specialist

Enjoy the spring, the sun and your renewed energy. Your body (and mind) will thank you!
