It turns out that sunlight that is effective in converting dehydro-cholesterol compounds into pre-vitamin D is not sunlight in the morning
Dream – During the Covid-19 pandemic, sunbathing has become a routine every morning. Sunbathing in the morning is believed to be able to increase the body’s immune system so that it can be avoided from Covid-19 infection.
Being unique, this vitamin can be produced by the body itself by involving exposure to sunlight.
According to dr. Jeff Aloys in ‘Virtual Launching Holisticare D3 1000’ Wednesday, May 5, 2021, sunlight causes dehydro-cholesterol compounds in the skin to turn into pre-vitamin D. The pre-vitamin D is then metabolized in the body to produce active vitamin D.
However, it turns out that sunlight that is effective in converting dehydro-cholesterol compounds into pre-vitamin D is not sunlight in the morning, but sun exposure at 10 am to 1 pm.

This is the optimal hour
This internal medicine doctor said that sunlight which is effective in the formation of vitamin D in the body is a type of UV B light with a wavelength of 280 to 320 nanometers.
“So there is a length of 280 to 320 nanometers, this is only found in the sun during the day at 10 to 1 in the afternoon,” added dr. Jeff.
In order not to increase the risk of skin cancer due to sun exposure during the day, the doctor who practices at the Brawijaya Hospital in Jakarta said that 12 noon was the optimal time for sunbathing because the risk of triggering skin cancer at that time was relatively low.
“The most optimal at 12 noon because the wavelength of UV B rays does not exceed 320 nanometers. If it exceeds 320 nanometers, that is the risk of causing cancer,” he concluded.
