Sleep is essential for our physical and cognitive functioning. Without adequate rest, we cannot operate at 100% and our endurance may be lower. For people who exercise regularly, sleep is even more important. This is because the body needs time to repair the damage that occurs during exercise. If you don't get enough sleep, you may be undermining your workout.

Sleep is when the muscles in your body repair damage that occurs during exercise
Exercise is a form of physical stress that causes micro-tears in your muscle fibres. These tears are what cause muscle soreness and fatigue after a workout. Sleep gives your body the time it needs to repair this damage and rebuild the muscle tissue. Without enough sleep, your body doesn't have time to repair and recover, which can lead to slower recovery times and a greater rate of perceived exhaustion.
The amount of sleep you need depends on the intensity of your workouts. High-intensity physical activity requires longer recovery times, so people who engage in this type of exercise regularly need to compensate with quality sleep to allow their bodies to recharge.
It's important to prioritise sleep alongside your fitness regimen. Sleep is just as important as eating healthily and exercising consistently. If you regularly neglect your body's need for sleep, you may be putting your body at greater risk for injury.

Sleep deprivation can lead to slower recovery time
Sleep is when the muscles in your body get the chance to grow and repair damage that occurs during exercise. When you don't get adequate sleep, you may be undermining your workout. Sleep deprivation can lead to slower recovery time. If you exercise consistently, you might need more sleep to compensate for the longer recovery time that high-intensity physical activity requires. The greatest benefits come from more intense exercise: a 2013 NSF survey shows that people who exercise vigorously reported significantly fewer sleep concerns than people who reported little to no physical activity.
Sleep is vital to your workout schedule, although it won't affect how your body responds to exercise. Instead, you're likely to run out of energy faster if you have less sleep, and your level of endurance may be lower. If you're not getting the recommended seven to eight hours of sleep per night, you need to rethink your schedule so you can make sure you do. You can't have one without the other; both are absolutely essential to you being able to operate at 100 per cent – not just in the gym, but in your everyday life, too.
For people who are physically active, sleep deprivation carries its own risks: a slower recovery time and a greater rate of perceived exhaustion. Long-term sleep deprivation has been linked to major health problems such as obesity, diabetes, and high blood pressure. A recent study shows that sleeping as little as six hours per night can have surprisingly negative effects on otherwise healthy adults.
It's important to stay committed to your fitness regimen, but don't prioritise that over getting quality sleep at night. Sleep is just as important as eating healthfully and exercising consistently. If you regularly neglect your body's needs, your body will suffer and you will be at greater risk for injury.
