Should you exercise or sleep? (Photo: Freepik)Many fitness buffs drag themselves out of bed to exercise even if they haven’t met their sleep requirements. While the duration of hours varies from person to person, the question is whether it’s advisable to rest it out? Dr Manjusha Agarwal, senior consultant, internal medicine, Gleneagles Hospital, Parel, Mumbai, said that when you haven’t slept well, it can be difficult to decide whether to sleep in or push yourself to go to the gym. From the perspective of sleep science, if you have not slept well, then prioritising recovery over exercise is usually the best choice, experts urge.
Sleep is the time when your body repairs muscles, balances hormones, restores energy, and supports your immune system. If you force yourself to exercise after a poor night of sleep, you may feel tired, unfocused, and more likely to injure yourself. Your workout quality will also be low because your body is already running on very little energy, said Dr Agarwal.
Poor sleep compromises the balance of hormones, reduces cognitive alertness, and increases the risk of injury due to slow reaction times, said Dr Anil Ramakrishna, senior consultant, neurology, SPARSH Hospital, Yelahanka, Bangalore.
“Skipping sleep to exercise also leads to an increase in the level of cholesterol, impacts the quality of workout and impairs the recovery of muscles,” he described.
If you slept less than 5–6 hours, it’s better to skip or delay your workout and get some extra rest, stressed Dr Agarwal.
“Even 60–90 minutes of additional sleep can improve mood, focus, and physical performance. You can always do a light activity later in the day, such as walking, stretching, yoga, or a short home workout. However, if you slept slightly less than usual but still feel okay, like 6 hours, you can choose a gentler form of exercise instead of a heavy gym session,” said Dr Agarwal.

A short nap for recovery, or allowing your body additional rest in the morning, helps regulate the circadian rhythm and supports metabolic function. “Once rested, an individual can engage in light movements like stretching or a low-intensity walk later in the day without stressing their body system,” said Dr Ramakrishna.
Avoid intense cardio or heavy weights on such days. The main rule is that sleep comes first. A well-rested body performs better, burns more calories, builds muscle faster, and stays healthier in the long run.
