{"@type":"Question","name":"What UV level is dangerous?","acceptedAnswer":{"@type":"Answer","text":"WHO UV index scale: 1-2 Low, no protection needed for short exposure. 3-5 Moderate, wear sunscreen and a hat for over 30 minutes outside. 6-7 High, seek shade during midday, apply SPF 30+. 8-10 Very High, minimise direct sun 11am-3pm. 11+ Extreme, avoid outdoor exposure during peak hours. In the UK, UV 6+ is common on clear summer days May-August."}},
{"@type":"Question","name":"How long until I get sunburn today?","acceptedAnswer":{"@type":"Answer","text":"It depends on the UV index and your skin type. SunScope shows a Burn time column estimating minutes to the sunburn threshold (one Minimal Erythemal Dose). At UV 8+, fair skin types I and II can burn in under 10 minutes. Medium skin types have around 20-25 minutes. Darker skin has more natural protection but is not immune. Burn time assumes no sunscreen and no shade."}},
{"@type":"Question","name":"What is the difference between UV-A and UV-B?","acceptedAnswer":{"@type":"Answer","text":"UV-A has a longer wavelength, penetrates deeper into skin, is present throughout all daylight hours, passes through glass, and is the primary cause of long-term skin ageing. UV-B causes sunburn directly and drives vitamin D production. UV-B is strongest when the sun is high and falls sharply in morning and evening. SunScope shows both indices separately."}},
{"@type":"Question","name":"How does shade affect how hot I feel?","acceptedAnswer":{"@type":"Answer","text":"On a sunny day shade can reduce felt temperature by 8-12 degrees because it removes the direct solar radiation load. However shade does not reduce air temperature or humidity, so on very humid days you will still feel uncomfortable in shade. SunScope shows UTCI for open sun exposure, so felt temperature in shade will be noticeably lower than the figure shown."}},

{"@type":"Question","name":"How hot does a car get in the sun?","acceptedAnswer":{"@type":"Answer","text":"On a mild 20 degree day with strong sunshine, the inside of a sealed car can reach 40-45 degrees within 20 minutes and over 50 degrees within an hour. On a hot 30 degree day it can hit 60 degrees. The glass acts like a greenhouse. SunScope calculates cabin temperature hour by hour. Above 35 degrees is dangerous for a child or pet. Above 45 degrees can be fatal within minutes."}},
{"@type":"Question","name":"Does opening car windows reduce the temperature inside?","acceptedAnswer":{"@type":"Answer","text":"Yes, significantly. Open windows allow convective airflow to flush hot cabin air out, reducing heat build-up by roughly 60-80% compared to a sealed vehicle. SunScope has a Ventilation toggle in the Vehicle column that shows the estimated cabin temperature with windows open alongside the sealed figure."}},
{"@type":"Question","name":"Is it safe to leave a dog in a parked car?","acceptedAnswer":{"@type":"Answer","text":"No. On any warm or sunny day a sealed vehicle heats up rapidly to temperatures that can cause heatstroke and death in animals within minutes. Dogs are at risk at cabin temperatures above 32 degrees. SunScope Vehicle column shows hourly cabin temperature. Amber (above 35 degrees) or red (above 45 degrees) means not safe for a dog, cat, or young child, even for a few minutes."}},
