Nobody is sure why dogs sleep so much. The amount of sleep that an animal needs depends upon its species. Horses and cows may sleep only three or four hours daily, because they require long hours of grazing to supply their bodies with sufficient food. Bats and opossums may sleep closer to 20 hours. The various breeds of dogs also seem to have different sleep requirements. Some very large breeds of dogs, like Newfoundlands, Saint Bernards, and mastiffs, often spend a great deal of their lives sleeping â perhaps up to sixteen or even eighteen hours a day.
When it comes to eating before exercise, it's all about timing. No matter what time of day you choose to exercise, make sure to plan your workout two to three hours after your meal. Going overboard with too much food right before a workout will leave you feeling sluggish and can lead to stomach discomfort.
Eating and exercise go hand in hand. When and what you eat can be important to how you feel when you exercise, whether it's a casual workout or training for a competition. Consider these eating and exercise tips. If you exercise in the morning, get up early enough to finish breakfast at least one hour before your workout. Be well-fueled going into a workout. Studies suggest eating or drinking carbohydrates before exercise can improve workout performance and may allow you to work out for a longer duration or higher intensity.
