As fitness routines, balanced diets, and wellness trends gain popularity, one crucial aspect of healthy living is often overlooked in Tanzania: getting enough sleep.
Health experts warn that poor sleeping habits are quietly affecting adults, especially those over 30, when the body’s natural ability to repair and regenerate begins to slow.
“Sleep is not optional; it is essential for your health,” said Dr. Mariam Charles, a lifestyle and wellness specialist. “Insufficient sleep can lower cognitive performance, weaken the immune system, and increase vulnerability to chronic conditions such as diabetes, hypertension, and depression. Many adults still assume that five hours of rest is adequate, but this is far from sufficient.”
Modern urban lifestyles, long working hours, and constant social media use have contributed to shorter average sleep durations. Many people stay up late to meet work demands or for leisure, often without realizing the long-term impact on their health.
Dr. Charles explained that sleep is a critical period during which the body detoxifies and renews cells. “Between midnight and 3 a.m., the body is most active in cleansing and regenerating itself.

Every day, new cells are formed, and the most effective way to support this process is through uninterrupted, restorative sleep. Naps or stimulants cannot fully replace a proper night’s rest.”
Age also plays a significant role in the body’s recovery process. “Young people recover quickly, but after 30, the regenerative capacity slows down,” Dr. Charles said. “This makes consistent, quality sleep even more important for maintaining health, energy, and overall well-being.”
Research shows that adults sleeping less than seven hours per night are at higher risk of developing metabolic disorders, heart disease, and mental health issues. Experts recommend cultivating good sleep hygiene, such as establishing a regular sleep schedule, reducing screen exposure before bed, and creating a quiet, comfortable bedroom environment.
Health professionals emphasize that while exercise and diet are essential for wellness, they cannot fully compensate for inadequate sleep. Prioritizing sufficient rest not only improves daily performance but also strengthens long-term health and resilience.
