Sleep & Gym

A good night's sleep is essential for overall health and wellbeing. According to the New Zealand Ministry of Health, around 30% of adults in New Zealand experience sleep problems. Regular exercise, particularly at the gym, can significantly improve sleep quality. In this article, we'll explore the connection between sleep and exercise, and how a gym routine can help reset your circadian rhythm.

The Science of Sleep and Exercise

Research has shown that regular physical activity can help improve sleep quality by reducing stress and anxiety, and regulating the body's circadian rhythm. A study found that exercise can increase the amount of deep sleep and rapid eye movement (REM) sleep, leading to better sleep quality and duration. In New Zealand, the organisation Exercise NZ offers a subsidised gym scheme, which can help make gym memberships more affordable and accessible to those who need it.

Best Time to Work Out for Sleep

The timing of your workout can impact your sleep. Exercising too close to bedtime can actually interfere with sleep, as it can stimulate the body and brain. It's recommended to finish your workout a few hours before bedtime to allow your body time to wind down. For example, if you plan to go to bed at 10pm, try to finish your workout by 6-7pm. This can help regulate your circadian rhythm and improve the quality of your sleep.

How a Gym Routine Resets Your Circadian Rhythm

A consistent gym routine can help regulate your body's internal clock and improve the quality of your sleep. Exercise can help expose your body to natural light, which is essential for regulating the circadian rhythm. Additionally, the physical activity and social interaction at the gym can help increase alertness and energy levels during the day, making it easier to fall asleep at night. With Exercise NZ's subsidised gym scheme, you can enjoy discounts of 40-70% off gym memberships, making it more affordable to prioritise your sleep and fitness.

Practical Steps to Improve Sleep with Exercise

Incorporating physical activity into your daily routine can have a significant impact on sleep quality. Start by finding a gym that suits your needs and schedule, and aim to exercise for at least 30 minutes, 3-4 times a week. You can also try incorporating relaxation techniques, such as meditation or deep breathing, into your bedtime routine to help improve sleep quality.
