- Impaired Motor Skills: It can negatively impact your coordination and reaction times, increasing the risk of accidents and injuries, especially while driving or operating heavy machinery.
- Weakened Immune System: A good night’s rest is essential for proper immune function. Lack of can weaken your body's defences against infections, making you more likely to fall ill.

- Impaired Long-Term Health: Consistently not getting enough sleep over time has been linked to a shorter lifespan and an increased risk of chronic diseases.
It's important to note that the effects of sleep deprivation can vary from person to person and depend on factors such as age, overall health and individual needs. To maintain optimal health and well-being, it's recommended to prioritise getting enough high-quality sleep on a regular basis.
How Much Sleep Do I need?
It is recommended to get at least seven to nine hours per night. If you're experiencing persistent sleep problems or deprivation, consider seeking guidance from a healthcare professional.
Causes of Lack of Sleep
Lack of can result from a variety of factors, both external and internal. Here are some common causes of deprivation:
- Poor Sleeping Habits (Sleep Hygiene): Engaging in behaviours that disrupt your natural sleep-wake cycle can lead to deprivation. This includes irregular slumber schedules, excessive napping during the day and using electronic devices before bedtime.
- Stress and Anxiety: High levels of stress, worry and anxiety can make it difficult to relax and fall asleep. Racing thoughts and a preoccupied mind can prevent you from getting adequate rest.
- Work Schedule and Shift Work: Jobs that require irregular or overnight shifts can disrupt the body's natural circadian rhythm, making it challenging to establish a consistent routine.
- Electronic Devices: The blue light emitted by smartphones, tablets, computers and TVs can interfere with the production of melatonin, a hormone that regulates sleep. Using these devices close to bedtime can make it harder to fall asleep.
- Caffeine and Stimulants: Consuming caffeine, nicotine, or other stimulants close to bedtime can disrupt sleep by making it harder to fall asleep and reducing quality.
- Medical Conditions: Certain medical conditions, such as chronic pain, asthma, allergies, gastroesophageal reflux disease (GERD) and disorders like insomnia or sleep apnoea, can lead to an inadequate night's rest.
- Medications: Some medications, including certain antidepressants, stimulants and decongestants, can interfere with sleep and contribute to sleep deprivation.
- Environmental Factors: Noise, light, temperature, and uncomfortable bedding can all affect your ability to fall and stay asleep.
- Lifestyle Factors: Alcohol consumption, particularly close to bedtime, can disrupt the sleep cycle and lead to fragmented sleep.
- Travel and Time Zone Changes: Rapid travel across multiple time zones (jet lag) can disrupt your body's internal clock, leading to difficulty falling and staying asleep in the new time zone.
- Life Transitions: Major life changes, such as childbirth, caring for a newborn, or adjusting to a new job or living situation, can disrupt sleep patterns.
- Age: Sleep patterns and needs change over the course of a lifetime. Adolescents and young adults may experience shifts in their sleep-wake cycle due to hormonal changes, while older adults might have more fragmented sleep due to factors like medical conditions or medication use.
- Substance Abuse: Drug or alcohol use can disrupt sleep patterns and lead to deprivation.
Supplements To Improve Your Sleep
Several supplements are believed to promote a better night's rest by addressing various factors that affect sleep quality and duration.
However, it's important to note that while some people may find these supplements helpful, individual responses can vary. Before adding any supplements to your routine, it's a good idea to consult with a healthcare professional, especially if you have underlying health conditions or are taking other medications.

- 5 Hydroxytryptophan (5-HTP): 5-HTP is a compound that the body converts into serotonin, a neurotransmitter that plays a role in mood and sleep regulation. Some studies suggest that 5-HTP supplementation may also improve quality.
- Passion Flower (Passiflora incarnata): Passionflower is a herbal remedy that has been used to treat anxiety and insomnia. It may help improve sleep quality by promoting relaxation.
- Vitamin B6: Vitamin B6 is involved in the production of melatonin, a hormone that regulates sleep. Ensuring adequate levels of vitamin B6 may support healthy sleep patterns.
