Irritation of the skin can be caused by all sorts of things, but it is particularly prevalent in the hot summer months. Here’s how to treat a range of ailments.
Any chemical that comes into contact with your skin can cause irritation, especially if you already have skin damage or eczema. At this time of year, sunscreen is a prime offender. Sunscreens contain components – such as zinc oxide or titanium dioxide – that block UV rays or chemicals – benzophenone, for example – that reduce the harmful effects of UV. You can be allergic to either type, but benzophenone allergy is more common. The clue is in the timing and distribution; if you come up in an itchy rash in areas where you apply the most cream, then stop using it, take an antihistamine and try other methods of protection against sun damage.Once the rash calms down, try a sunscreen designed for babies; they tend to be the most hypoallergenic.
Itchy skin can be part of a generalised allergic reaction; and prescribed, herbal or over-the-counter medicines are a common cause. The rash will be itchy, red and look blotchy or like raised hives. It can start up to several weeks after beginning a new drug, gets better when you stop the drug and flares up again (often worse) if you restart. Any drug can cause an allergic reaction – even if you have taken it before with impunity. Antihistamines (eg cetirizine), steroid creams and moisturisers may help, but there’s no substitute for identifying the likely culprit and stopping it, with medical advice.
A food allergy can cause a raised, itchy rash (hives). You may get an itchy sensation in the mouth, swelling of lips and roof of mouth, may feel or be sick and then come out in a rash. Mild food allergies may just cause a rash, though you usually get at least a bit of lip tingling as you eat the offending food. Hairy fruits such as kiwi are a common allergen. Allergic reactions often get worse with repeated exposure, but if it’s a food that you don’t eat often, it can be hard to identify it. Allergy testing is available but it helps if you have some idea about likely triggers. Take an antihistamine as soon as possible. A severe allergic reaction (anaphylaxis) is rare but potentially life-threatening; anyone who has difficulty breathing or tightening of the throat associated with an allergic reaction should see a doctor and consider carrying adrenaline at all times.
