Sensitivity to heat is a recognized symptom of Multiple Sclerosis (MS).External and internal increases in body temperature alike can cause either a block or the slowing down of messages moving along a nerve. This can temporarily cause the symptoms of MS to become worse. Elevating body temperature, even by ½°C, is enough to have a dramatic effect.
Symptoms usually settle again when the nerve returns to its normal temperature by resting or cooling. Internal causes of increased body temperature include fever and infection, having a very hot drink, and menstruation. External causes include hot weather and hot showers or baths. Heat sensitivity is also closely related to fatigue.
This article presents several tips to survive the summer by avoiding increases in body temperature.
Food and Fluid Intake
- Keep up liquid intake to help the body cool. Carry a water bottle whenever you leave home.
- Aim for at least an extra couple of large glasses of cool fluid a day. This helps restore body fluids lost by sweating and will help the fatigue that comes from heat. If you have problems with your bladder, just take sips of water at a time, say 2-3 mouthfuls. Even sucking on an ice cube can help.
- Drinks with caffeine such as coffee and colas increase the metabolic heat in the body and therefore should be avoided.
- Eat small meals and more often. The larger the meal, the more metabolic heat your body creates breaking down the food. Avoid foods high in protein as they also increase metabolic heat.
- Try chrysanthemum tea, which is reputed to be a cooling herb which clears the head.
- Wear a hat with a wide brim when out in the sun.
- Carry a small handheld portable fan when on outings.
- Wear a wet bandana around the neck.
- Keep a face flannel in a plastic bag in the fridge or freezer and place between your back and the car seat; this is a great way of staying cool while on the move.
- Use cotton wherever possible for trousers, skirts, shirts, tops, etc.
- T-shirts are cool, easy to put on and off if you buy a slightly bigger size; they also absorb sweat, thereby keeping you cool.
- Light colours are best, they reflect the sunlight and stop you from heating up.
- Wear cotton underwear, especially if you sit a lot and if possible wear knee highs rather than pantyhose.
- Men should avoid nylon socks; cotton is much cooler.

Planning Your Day
