Heat and Hydration

Heat exhaustion

Don’t Ignore the Signs of Dehydration

Riding may not appear to be a very physical activity to some, but motorcyclists are vulnerable to dehydration due to the drying effect of the wind and exposure to the weather. Many of the symptoms of dehydration can affect your judgement and impair your ability to operate a motorcycle safely.

Mild to moderate dehydration is likely to cause:

  • Dry, sticky mouth
  • Sleepiness or tiredness — children are likely to be less active than usual
  • Thirst
  • Decreased urine output
  • Headache
  • Dizziness or lightheadedness

Severe dehydration, a medical emergency, can cause:

  • Extreme thirst
  • Irritability and confusion
  • Very dry mouth, skin and mucous membranes
  • Little or no urination — any urine that is produced will be darker than normal
  • Low blood pressure
  • Rapid heartbeat
  • Rapid breathing
  • In the most serious cases, delirium or unconsciousness

You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment. The safest approach is preventing dehydration in the first place. Keep an eye on how much fluid you lose during your ride and drink enough liquids to replace what you’ve lost.

10 tips to beat dehydration while riding

  1. Don’t drink too much alcohol the night before a ride. It has a diuretic effect which means it causes you to urinate more water than you take in, which means you are losing fluid. And you can’t counteract that by drinking lots of water because most of it will go out in your urine. Obviously, don’t drink alcohol while you are riding!
  2. Start drinking water as soon as you wake and keep sipping water right up until you get on your bike. It takes about half an hour for water to reach your muscles. Guzzling water just before a ride is not good as it can make your stomach to cramp.
  3. Wear ventilated motorcycle clothing. Leathers may protect you better in a crash, but they create a “microclimate” which impairs your ability to lose heat. As a result you will produce more sweat to decrease your core temp. Instead, wear a flow-through jacket. There are heaps of options on the market. Make sure they have vents in the back so the air flows through. Also, loosen the sleeves so you get plenty of air on your wrists which have a lot of blood vessels close to the skin to effectively cool you down. However, be aware that a flow-through jacket cools you down because it is drying the sweat off your skin which can lead to dehydration. Don’t be fooled by your level of coolness; you still need to keep drinking.
  4. Don’t be tempted to remove your jacket in the heat! Exposed skin may feel cooler, but that’s because the sweat is evaporating quicker, but that is just making you more dehydrated. And while your skin feels cool, you’ll be tricked into staying in the sun longer which leads to sunburn. That also leads to dehydration because your body needs water to repair and renew damaged skin.
  5. Get a water-dispensing unit so you can continue to take small sips of water while you are riding.
  6. Stop more often than usual and hang out in the shade or in an air-conditioned cafe. Since you are drinking lots of fluids, you will probably need to stop anyway!
  7. While you’re stopped, have a coffee, but take it easy. No need to swear off your favorite caramel latte, but avoid excess coffee. That also goes for caffeinated drinks such as Red Bull. High levels of caffeine have a diuretic effect just like alcohol.
  8. While having a coffee break, avoid having too many sweet cakes, donuts and muffins. Sugar can dehydrate you if it gets to very high levels in your blood. This can happen if you are a diabetic, take certain medications or have an infection or some organ diseases. Sugar causes your kidneys to produce more urine to eliminate the sugar, leading to dehydration. Likewise, don’t drink too many sugary drinks. Best to stick to plain water, real fruit juices with no added sugar or drinks such as Gatorade that replace salts and minerals lost in sweat.
  9. We’ve talked a lot about urine and it’s important that you monitor the color. It should be a straw color. If it’s too dark, you are dehydrated.
  10. Sweat also depletes your body of sodium and if it becomes too low, it can cause many of the same symptoms as dehydration. The average diet probably has enough sodium, but it’s good to have a little bit of salt on your meals or drink sports drinks that have a sodium supplement. However, beware of sports drinks with caffeine and sugar.
