When the demands of work, a busy social life and personal goals leave us feeling stretched thin, our sleep is often the first thing that takes a beating. Usually seen as a luxury we can’t afford, adages like “I’ll sleep when I’m dead” are commonly thrown around, viewing sleep as something that’s not really necessary & often as a waste of time. This, especially when it comes to your health, couldn’t be further from the truth. Sleep is not merely a time of rest; it is a fundamental pillar of overall health, intricately tied to not only your physical fitness, but a myriad of mental & emotional health processes. To understand the connection & improving sleep for better fitness, we spoke to Abhishek Munian, a Fitness Coach, delving into the mechanisms that make sleep a critical component of a healthy and active lifestyle.
The Basics
Sleep is divided into four primary stages all responsible for their own functions in our bodies. The initial three are recognised as non-rapid eye movement (NREM) sleep, often referred to as peaceful sleep. The fourth stage, rapid eye movement (REM) sleep is also called active sleep. All of these stages are directly linked to physical recuperation and also play a specific role in preserving your brain’s cognitive abilities, ensuring your well-being and preparing you for each day.
Sleep is a time for tissue repair, muscle growth, and the consolidation of memories. Hormones crucial for physical well-being, such as growth hormone and testosterone, are primarily secreted during deep sleep.
This is the time when your body works on repairing the wear and tear of the day, from mending muscle fibres after a workout to enhancing your immune system.
The Sleep – Fitness Connection
The interplay between sleep and fitness is a relationship that extends far beyond mere coincidence or casual connection. Quality sleep plays an integral role in an effective fitness regimen & affects your;
- Energy and Performance: The most obvious link between sleep and fitness is energy. A good night’s sleep provides the necessary physical and mental energy to engage in physical activities, whether it’s a morning jog, an intense gym session, or a yoga class. Without adequate sleep, you’re likely to feel sluggish and unable to perform at your best.
- Muscle Recovery and Growth: Deep sleep is the time when your body undergoes muscle repair and growth, effectively rebuilding the tiny micro-tears in the muscle fibres that were the result of your workout. When sleep is inadequate, this crucial muscle recovery and growth phase can be compromised & may lead to slowing down of hypertrophy or overtraining, a condition where the body isn’t given ample time to heal, potentially resulting in slower recovery and performance plateaus.
- Hormonal Balance: Studies have indicated that insufficient sleep, specifically less than 7 to 9 hours per night, in men can result in reduced testosterone levels, which can have adverse effects on their overall health. Poor sleep can also disrupt the balance of hormones like leptin and ghrelin, which control hunger and fullness. This can lead to overeating and weight gain, which, in turn, can impact your fitness goals.
- Mental Focus and Coordination: Physical fitness isn’t just about the body; it’s about the mind-body connection. Sleep is essential for maintaining mental focus, coordination, and balance all of which help you in your workouts or physical fitness.
- Injury Prevention: Fatigue from lack of sleep can increase the risk of accidents and injuries during exercise. Proper rest allows your body and mind to be alert, reducing the chances of accidents that could set back your fitness routine.
Building a Healthy Sleep Relationship
Quality rest significantly impacts your physical performance, workout recovery, and even your mental focus. Optimising your sleep should be an integral part of your fitness routine, not just an option and if you feel like your sleep could do with a helping hand, the following hacks may help in improving sleep for better fitness;
- Reframing Sleep: Recognise that sleep is a non-negotiable component of your fitness regimen. Strive for 7-9 hours of restful sleep each night. Prioritise sleep as you would your workouts and nutrition.
- Consistency: Your body thrives on consistency and a regular sleep schedule helps regulate your internal body clock. Keeping a steady sleep routine, even during weekends ensures your body can anticipate when it’s time to rest, making it easier to fall asleep and wake up feeling refreshed.
- Create a Sleep-Friendly Environment: Creating an optimal sleep environment in your bedroom, characterised by darkness, quietness, and a cool temperature, is essential for promoting quality sleep. Darkness helps trigger the release of the sleep-inducing hormone melatonin, while a quiet setting minimises disruptions that can fragment your sleep. Maintaining a cool temperature ensures your body doesn’t overheat during the night, supporting uninterrupted and restorative sleep.
- Limit Screen Time: Avoiding screens before bedtime is advisable because the blue light emitted from phones, computers, and other devices interferes with our sleep-wake cycle. Blue light mimics natural daylight, which signals to our brains that it’s time to be awake and alert. Exposure to this light suppresses the production of melatonin. Consequently, using screens before bedtime can lead to difficulty falling asleep and disrupted sleep patterns, making it harder to achieve restorative rest.
- Watch Your Diet: Pay attention to your diet and beverage choices, particularly in the hours before bedtime. Steer clear of heavy meals and caffeine intake close to bedtime. These can disrupt your sleep by causing discomfort and alertness when you should be winding down. Opt for lighter, easily digestible evening meals and consider soothing, caffeine-free beverages like Chamomile tea to promote a restful night’s sleep.
- Stay Active: Engaging in regular exercise can promote better sleep patterns. But, time your workouts wisely as intense exercise too close to bedtime can actually have the opposite effect, making it more challenging to fall asleep. Aim to complete vigorous workouts at least 2-3 hours before bedtime to allow your body time to wind down, setting the stage for a peaceful night’s sleep.
