I've tried to explain this problem to a doctor but she didn't believe me. Sunlight makes me sleepy. When I am in a place with natural lighting I am very tired, I can't focus, I have trouble keeping my eyes open, I'm disoriented, my mind is foggy, I have every symptom of severe fatigue. When I move into a room with little or no natural light, my mind clears and I wake up. I am alert and focused at night or in moderate artficial lighting. Strong fluorescent or full spectrum lights cause the sleepiness as well, but not as severely as sunlight. Even if I have had a full night's sleep and have only been awake for an hour or two, I can fall asleep in a sunny room. This doesn't happen in a dark or artificially lit room.

I know this isn't caused by sleep deprivation, depression, caffeine or drug withdrawal, or any of the normal causes of fatigue because I am only affected in sunlight, never in dark or artificial light. As soon as I walk into a sunny room I get sleepy and disoriented, but when I go back into a dark or artificially lit room I wake up again. My fatigue is being caused by sunlight - what I need to know is what could be behind this and if there's any treatment.

  • You have extreme photophobia and need to be examined by an opthalmologist to determine if you need treatment for something serious with your eyes.

  • I get the same thing! I cant go out till the day is almost over, if i want to be able to some degree enjoy it. If i go out earlier i cant function, and i wont recover till the next day or 2!Thank you to both of you. People seem to disregard this as being a symptom. This is one of my most frustrating symptoms. It also takes me a day or two to recover. I have barely left the house at all in the last 6 months. I also have extreme heat sensitivity, spasms and pain in my eyes that have effected my vision, burning prickly feeling in my skin, chronic diareha, my teeth are falling out, unbearable back/neck/head pain, and I fall a lot now. I get confused often. I am not sad, and I don't "freak out" about things that are not a big deal. Bad doctors are a big deal. I do physical therapy exercises most everyday. I eat a mostly all organic diet and take vitamins. I brush twice a day with a very soft bristle brush and floss three times a week. I am not on any medication or drugs of any kind. My feet and hands fall asleep at least 5 times a day. I have no idea what is wrong with me and my doctor does not care.

There are conditions in which the sun can affect one and trigger off symptoms.. autoimmune conditions. Offhand thou i cant think of the names of the ones i've heard about in the past.. umm one is Systemic Mastocytosis, sun can trigger it off but your case doesnt appear at all like the one person i know has this (as that is an allergic autoimmune response), so i think it's something else. There is another autoimmune condition .. it starts with a "P" which sun triggers off but i cant remember the symptoms either. These sun triggering conditions are rare and ones most doctors will miss diagnosing due to lack of knowledge on them. These illnesses do cause tiredness in response to sun. Keep hunting for the name of what you have got.

  • I just found the name of one of the other conditions in which the sun can cause issues in. Porphyria (ive no idea what symptoms it causes so anyone here with problems will have to find that out themselves). It can cause burning skin like one poster mentioned thou. http://www.drinkdeeplyanddream.com/realvampire/porphyria-info.html

  • omg.. im not the only one! i never understand how all the other people dont feel the same way. like no one i ever meet ever said they felt the same way. i always thought im kinda crazy for it and try to ignore it... but its kinda difficult when you feel like fainting and get moody and irritated and drowsy etc. i never feel that way at night or when the sun is down. its always when its bright sunny and lots of people around.. it makes me feel so awful
