Motion Sickness: Prevention, Causes, and Treatment Tips

Motion sickness, or travel sickness, occurs when the movement of a car, train, or boat you are traveling in causes a mismatch between the signals from the balance sensors in your ear and the sense of balance you get through your eyesight. Think of being on a boat - it feels like it's rocking (the sensor in your ear tells your brain you're in motion), but when you look at the horizon, it's flat and still (your eyes tell your brain that you're stationary). This mismatch can cause some people to have symptoms of nausea, dizziness, headaches, and feeling genuinely unwell. If you are on a mode of transport for more than a couple of days (such as on a cruise), the majority of people will find their body adapts, and the symptoms improve. It is not known why some people suffer from motion sickness more than others. It is more common in women and people who suffer from migraines. It is also very common in children; however, the majority will grow out of it through their teenage years.

Insect Bites or Stings: Symptoms and Treatment

The majority of insect bites/stings can be managed at home and should heal within 3 - 5 days. They tend to cause a round, red, swollen lump that can be painful (typically with insect stings) or itchy (typically with insect bites). Some insects can bite a number of times, causing multiple lumps across an area of the body. There may be a small allergic reaction to the bite or sting, which will be seen as a wider red/swollen ring around the bites. The most common stings are from bees and wasps. In a small number of people, an insect sting can cause a serious and dangerous allergic reaction (known to medical professionals as anaphylaxis). The symptoms of this can be feeling dizzy, sick, or faint, and swelling, particularly in the mouth and face resulting in difficulty breathing. If you suspect this is happening, call 911 immediately.

Hydration, Dehydration & Heatstroke: Treatment

Ensuring adequate hydration to help our bodies remain healthy can be a tough task, especially in hot conditions, and during strenuous activities or exercise. Hot temperatures and increased water and salt losses can lead to dehydration. Mild dehydration may be felt as thirst, headache, mild dizziness, reduced need to urinate, and dry skin. In its more severe form, dehydration can result in reduced alertness, fatigue, muscle cramps, loss of consciousness, and long-term damage to your kidneys.
