Morning sunlight can be a powerful ally for our health, according to specialists cited by the Polish publication Medonet. Here’s what they say about 30 minutes of sun exposure before 10:00am.
The benefits of morning sun exposure
Exposure to sunlight for 30 minutes before 10 a.m. helps regulate the circadian rhythm, improves mood and increases energy levels, according to Professor Claas Lahmann from the University Hospital Freiburg.
“Sunlight in the morning is the best alarm clock for our internal rhythm.”
This simple habit stimulates the production of serotonin, known as the “hormone of happiness”.
Correct exposure to sunlight can not only make us happier, but it can also contribute to a better quality of sleep.
“Studies show that people who spend about 30 minutes in the sun before 10 a.m. fall asleep earlier and have a more restful sleep,” adds Lahmann.
In addition, social interactions may increase when we are more active, which has an additional benefit to our well-being.
However, excessive exposure to light can disrupt the circadian rhythm.
“This can cause difficulty falling asleep and irritability the next day. However, in the summer we need less sleep than in the winter – a reduction of 30 minutes to an hour is completely fine,” says Professor Lahmann.
The impact of sunlight on heart health
Sunlight can also positively influence cardiovascular health. Professor Thomas Münzel, from the University of Mainz, points out that “sunlight can cause the skin to release substances that dilate blood vessels, such as nitric oxide, slightly reducing blood pressure.”
However, he warns, “the dosage is essential, especially this summer, it is extremely important to differentiate between the beneficial natural light and the dangerous heat.”
Prolonged exposure to intense heat can lead to serious cardiovascular problems, such as low blood pressure, dehydration, or an increased risk of heart attack and stroke.
“Heat should be treated as seriously as ice in winter,” warns Münzel, recommending physical activity early in the morning or late in the evening, proper hydration, wearing light clothing and avoiding sun exposure during lunchtime.
Sunlight also helps improve cognitive functions
In addition to the physical benefits, sunlight also contributes to the improvement of cognitive functions. Vitamin D, produced by the skin under the influence of UV-B rays, plays an essential role in brain health. Studies have shown that deficiency of this vitamin is associated with concentration problems, information processing difficulties and emotional instability.
“After correcting the deficiency, approximately 50% of these disorders improved,” says research cited by Medonet.
Moderate sun exposure also supports the immune system and helps protect the central nervous system, according to a study by the University of Münster.
What are the risks of sun exposure?
Although exposure to the sun has many benefits, we must be aware of the associated risks. Direct and prolonged contact with the sun’s rays can lead to burns, premature aging of the skin or even skin cancer.
Also, high temperatures can have a negative impact on the digestive system. UV rays help reduce stress and boost immunity, but excessive heat can lead to gastrointestinal problems, such as indigestion or infections caused by spoiled food. Professors Lahmann and Münzel advise adapting our behavior to extreme weather conditions to prevent risks.
To reap the benefits of sunlight, exposure must be moderate and controlled. It is essential that we gradually get our skin used to the sun and always use sunscreen.
