Is It Normal to Only Sneeze When Exposed to Bright Light?
As a 16-year-old male, standing at 5'9" and weighing 150 pounds, I've noticed an unusual pattern with my sneezing. I tend to sneeze rarely on my own—only when I’m exposed to bright light. In the absence of such light, sneezing doesn’t occur for me at all. I’m curious about whether this is a common phenomenon. Should this raise any concerns? Might my sneeze reflex be malfunctioning?

It's actually quite interesting that you're noticing sneezing primarily when exposed to bright light. This phenomenon is known as the "photic sneeze reflex" and is relatively common, affecting an estimated 18-35% of the population. So, no need to worry—it's not a sign of a malfunction in your sneeze reflex, but rather, a unique characteristic of how your body responds to certain stimuli.
Explanation
The photic sneeze reflex occurs when bright light (like sunlight) triggers your body's sneezing mechanism. The exact reason why this happens isn't fully understood, but it may involve the connection between your optic nerve (which responds to light) and the nerve pathways that control sneezing. For most people, this reflex is harmless and doesn't indicate any underlying health issues.
Next Steps
-
Monitor Your Symptoms: Since your sneezing is primarily triggered by bright light, note if there are other factors involved (like allergies) that could contribute to your symptoms.
-
Consider Light Conditions: When you're exposed to bright light, try wearing sunglasses or hats with brims to see if they prevent your sneezing. This may help manage the reflex in situations you find uncomfortable.
-
Stay Hydrated: Keeping your body hydrated can help your overall respiratory health, even if your sneezing is light-specific.
-
Consult if Needed: If you start to experience other symptoms (like nasal congestion, persistent sneezing unrelated to light, or any discomfort), it may be helpful to discuss this with a healthcare provider.
Overall, since you're not experiencing any other concerning symptoms, this reflex is generally benign. Just take note of your triggers and how best to manage your environment. If you have further questions or changes occur, feel free to discuss them!

Excessive Electrical Shocks Encountered
Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
Urinalysis Inquiry
Subject: Urinalysis Results Review Age: 23 Height: 5'2" Weight: 101 lbs Greetings! I would appreciate it if you could review my urinalysis findings. The test was conducted yesterday, just one day prior to the start of my menstrual cycle, and I am now currently on my period. Below are the details of my results, as I need this information to fulfill a prerequisite for my employment. Additionally, I would like to know whether my menstrual cycle may have influenced the outcome of the test. I typically experience frequent urination, yet I do not have any discomfort or pain while urinating.
Combining Ketorolac with Alcohol: Is It Safe?
Recently, I unknowingly mixed a 10mg dose of ketorolac with half a bottle of 4.5% beer. At that moment, I wasn't aware of the potential risks involved in this combination. It wasn't until I was partway through my drink that I thought to look it up. Now, I’m wondering if it’ll be fine for me to have a drink tomorrow night after stopping all ketorolac use, especially since this medication hasn’t been effective for my pain relief. To give you an idea of the timeline, I took ketorolac around 2 PM and didn’t start drinking until 11 PM.
Concerns About My Eye Condition
I'm a 19-year-old female, weighing 190 pounds and standing 5'5". Lately, I’ve noticed some troubling changes in my eyes. There are prominent, red veins extending from the inner corners of my eyes into the irises. Additionally, there are bright red streaks and pools forming at the lower part of both eyes beneath the eyelids, bordered by a yellowish hue. When I consulted two different doctors, they were unable to pinpoint the issue and simply recommended lubricating eye drops. Unfortunately, the condition seems to be deteriorating, with the redness spreading further. While there is no significant pain, keeping my eyes open feels like a struggle, and my vision has become increasingly blurry, leading to some headaches. I’ve been unwell recently, but I’m uncertain if this has any relevance to my eye problems. Any advice or insights would be immensely helpful.
Experiencing Numbness in the Right Arm or Leg?
Hello! I’m a 17-year-old assigned female at birth, weighing approximately 110 pounds and standing around 5 feet 2-3 inches tall. At the moment, I’m not taking any medications and I don’t smoke. Recently, I’ve been facing a peculiar issue where my right leg or arm occasionally becomes numb. This sensation only impacts my right side and never the left. It can occur at any time, both during day and night. Typically, the numbness in my leg arises when I’m lying in bed, although I also experience it randomly throughout the day. I’m curious if anyone has any insights or thoughts about whether this could be something more serious than just a problem with my posture, haha!
