Battling sleepless nights? Here are the health risks you could face
By Katemarthason Okudo, May 15, 2026Across many parts of Kenya, especially in a busy city, sleepless nights have slowly become part of daily life. Early morning commutes, long working hours, studies, side hustles, and endless screen time are stretching the day far beyond what the body can comfortably handle.
For many people, going to bed late and waking up early has become routine rather than an exception.
What makes this trend more concerning is that most people do not even notice the damage at first. The body adapts to tiredness, and people continue pushing through fatigue with strong tea or coffee. Over time, this creates a cycle where rest becomes less of a priority, even when the body clearly needs it.
Health specialists warn that this kind of routine sleep loss is not harmless. It builds up slowly and affects both physical and mental well-being in ways that are easy to ignore in the beginning.
How lack of sleep affects the body and mind
Sleep is the time when the body repairs itself, balances hormones, and supports brain function. Without enough of it, several systems begin to slow down. People may experience reduced concentration, mood changes, frequent headaches, and low energy during the day.
Poor sleep has been linked to more serious health risks. These include high blood pressure, weakened immunity, weight gain, and increased stress levels. Mental health is also affected, with higher chances of anxiety and depression when sleep is consistently disrupted.
The World Health Organization explains that quality sleep is essential for maintaining overall health and preventing non-communicable diseases. Similarly, the Centers for Disease Control and Prevention recommends at least seven hours of sleep for adults to support proper body and brain function.
Despite these warnings, many people continue to underestimate how serious a lack of sleep can become, especially when symptoms are not immediately visible.
Modern lifestyle pressures are making rest harder
One of the biggest causes of sleepless nights in Kenya is the pressure of modern living. Many people are multitasking multiple responsibilities just to keep up with rising living costs. This often means extending work hours or using nighttime to complete unfinished tasks.
Technology has also changed sleeping habits. Phones and laptops keep the brain active late into the night, with social media, entertainment, and work emails delaying rest time. The blue light from screens can interfere with the body’s natural sleep cycle, making it harder to fall asleep even when someone is tired.
Stress is another major factor. Financial worries, job insecurity, and daily urban challenges often follow people into bed. Instead of resting, the mind continues processing the day’s problems, leading to restless or broken sleep.
Experts recommend setting boundaries around screen use, maintaining a consistent sleep schedule, and creating a calm sleeping environment. Even small changes, when done consistently, can improve sleep quality over time.
