An NHS surgeon and TikToker has revealed the important correlation between sunlight and your body – advising that getting your hit of the great outdoors is the most important thing you can do every morning.

Dr Karan Rajan, a surgeon and lecturer at the University of Sunderland, shares his experience and knowledge with his 4.7 million followers on TikTok.

In a recent clip, he informs his viewers about the one thing you should do every morning without fail.

Dr Karan goes on to explain that the best way to regulate your circadian rhythm – energy, focus, physical and mental health – is to receive as much sunlight as possible.

However, a sunny day isn’t necessary for this to work, as going on an early morning walk or even just looking outside your window during overcast weather can still do wonders for the body.

Dr Karan further explains that going a few days without ample sunlight exposure can cause some major biological disruptions to several body systems.

Adrenaline, cortisone and serotonin production will be affected, as well as vitamin D synthesis and regular sleep/wake cycles, which cause physical and mental health consequences.

In the clip, Dr Karan adds: “Remember, even through cloud cover, sunlight still works for you.

“Unless you live underground or in a cave, you should be doing this – get some sunlight first thing in the morning.”
