According to Wikipedia a drug is any substance (other than food that provides nutrtional support ) that causes a temporary physiological change in the body.
People typically begin to lose 1 to 2% of their muscle mass each year starting in their 30s or 40s unless they’re already doing weights, so the older cyclists had much more room for improvement.
Imagine starting your car in sub-zero temperatures and putting it into gear without waiting for the engine to warm up. That’s a disaster waiting to happen.
The same is true for the human body. Without water to wake up and turn on the body in the morning, you may be running on empty. This is especially true if you skip breakfast.
A glass of cool water right after you wake up tells your body that it’s time to get going. Like a gently flowing stream that pushes along debris and rocks, your circulatory system needs fluid to get rid of stubborn free radicals and residue from burned calories used by your metabolism during the night.
Drinking water before eating helps you feel fuller. This means you’ll be less likely to scarf your food down. When you’re hydrated the stomach is also prepared for food. Water wakes up taste buds and moisturizes the stomach lining so brittle or acidic foods won’t be uncomfortable. Having a glass of water moistens the mouth and clears out leftover tastes from earlier food, drinks or smoking in anticipation of the coming meal or snack.
If you’re hungry between meals, pour yourself a tall glass of fresh drinking water first to see if you’re dehydrated. Sometimes people think they’re hungry when they’re really just thirsty. Drinking water before a snack or with one will help you feel full faster, helping keep calorie intake in check.
Depending on the temperature, humidity and your body’s fluid levels, you may need one or several large glasses of water to protect you against dehydration during and after your workouts. Hydration is essential to protect you against heat stroke in warm weather and frostbite in cold temperatures. Your body’s circulation plays a protective role in both extremes of temperature and needs water to function properly.
Following vigorous exercise, you may need to drink a lot of water to replace fluids lost through perspiration and urination.
If you’re feeling the need for a nap but can’t take one, have a glass or two of water instead.
